1.1 Product Description

The Panametrics-NDTTM Model 25HP PLUS is a state-of-the-art, hand-held ultrasonicthickness, velocity and time-of-flight gage with an A-Scan display. This precisionmicroprocessor-based instrument uses pulse-echo and thru-transmission techniques tomeasure material thickness when both sides of the test material may not be easilyaccessible. The gage can also measure sound velocity and pulse transit time in most solidsand liquids.

The Model 25HP PLUS is designed with one basic goal in mind – simplicity of operation.

A wide thickness range with accurate and repeatable measurements make the 25HP PLUSextremely versatile. The gage’s three modes of operation and A-Scan display allow theuse of contact, delay line and immersion transducers.

A unique feature, Application Recall, simplifies gaging. This function allows the use ofboth Stored Standard and Custom Stored Application Setups. In general, one of the 25Stored Setups is adequate for most applications. If, however, your application requires aspecial setup, the 25HP PLUS offers 35 Custom Setup locations. Custom setups may beprogrammed by the user or by Panametrics-NDTTM.

The Model 25HP PLUS has an internal datalogger that can store over 18,000 fullydocumented thickness measurements, or 1,750 thickness readings with waveforms.Identify each measurement reading with an alphanumeric identification number up to 16alphanumeric characters in length. The identification number represents a physical

location, as determined by the user. The gage increments the identification numbersautomatically for each reading, or you can access any alphanumeric location randomly.This incremental process allows for maximum flexibility and easy review of the storedthickness readings for each location.

The Model 25HP PLUS also comes equipped with an RS-232 communications port. Thiscommunication port allows the 25HP PLUS to interface with a computer or printer todownload thickness readings, or to remotely setup and calibrate the Model 25HP PLUSfrom a host computer.

2.2 Identifying Display Elements

The gage screen is a Liquid Crystal Display (LCD) and best viewed from straight above orslightly below the surface rather than from the side. The display may be slow at

temperatures below 32oF (0oC). The figure below identifies the various sections of theModel 25HP PLUS display.

Figure 2 Identifying Display Elements

General Information: The main function of the display is to show the echo waveform andto display the thickness reading received by the transducer as measurements are made.The received echoes are amplified before being shown on the display. The waveform traceis called the A-Scan display. This type of waveform allows a skilled operator to verify thatthe gage signal being used to make a thickness measurement is the correct backwall echo

and not a noise, material anomaly, or the second multiple echo. This verificationwaveform along with all pertinent calibration information can be stored with the thicknessvalue in the internal datalogger. An experienced operator can also use the echo waveformto learn more about the quality of the measurement than is given just by the thicknessvalue, which includes observation of indications that may be too small to be measured bythe gage.

Press the [FREEZE] key to freeze the display. Adjust the thickness range (horizontalscale) or expand the measured echo by using the Zoom mode.

When operating in the Minimum orMaximum Measure mode, the waveform associatedwith a minimum or maximum reading is internally captured and recalled to the screenwhen the transducer is uncoupled. Furthermore, any waveform that is stored in thedatalogger memory can be shown on the waveform display for review or comparison tothe current measured waveform. Such recalled waveforms may have been recently savedor may have been downloaded from a computer data file.

Thickness Display: The top portion of the display shows the current Filename, IDnumber, Comments, and any previous stored thickness values.

The lower part of the display functions as a general purpose thickness measurementdisplay; as a control panel for calibrating and setting up the gage, in addition to displayingstatus conditions, error messages and warnings. The large characters are used to shownumerical values such as thickness and velocity. This area also shows flags that describethe numeric data and/or the gage operating modes, and the battery status.

2.3 Identifying Connector Configurations

The 25HP PLUS can be used with three different Pulser Receiver configurations, PulseEcho, Thru-Transmission, and Pitch Catch. Refer to the diagrams below for transducerconnection for different modes.

Figure 3 Transducer Connections

In Pulse Echo P/R configuration, connect the transducer to the Channel #1 connector.

In Thru-Transmission and Pitch Catch P/R configuration, connect the receivingtransducer to Channel #1 connector and connect the pulsing transducer to Channel #2connector.

2.4 Using the Battery Pack

The Model 25HP PLUS Gage is powered by an internal 6V battery pack usingrechargeable NiCad batteries or 6 AA alkaline batteries. The NiCad battery pack isrecharged through the Model 36CA PLUS Charger/AC Adapter unit that is supplied withthe gage. The 36CAPLUS does not recharge the alkaline batteries; you must replace thealkaline batteries after discharging. The Model 25HP PLUS can also be operated directlyfrom AC power using the Charger/Adapter.

The batteries are fully charged when shipped, but for maximum operating time, rechargebefore using. Recharge batteries only with the Model 36CA PLUS Charger/Adaptersupplied with the gage. Other chargers may reduce battery life and/or damage thebattery and void the warranty on the gage.

Even a discharged battery maintains the internal stored calibration values and thicknessdata for several weeks. However, to maintain optimum battery life, do not leavedischarged batteries for long periods of time.

2.5 Monitoring the Battery Charge

The battery charge indicator, or battery status meter, displays the percentage of batteryremaining capacity in bottom right hand corner of the display. Remember that if thebattery is charged for at least 2 hours, then 99% charge indication corresponds to over 25hours of operation. However, if the battery is charged for less than 2 hours, then 99%charge indication corresponds to proportionally fewer hours of operation.

Note: The battery charge indicator shows a rotating bar when the when the chargeris plugged in; however, it cannot be used to indicate when full charge isreached while charging. The gage displays a “C” indicating that the battery ischarging. The gage displays a “S” indicating that charging is complete.

2.6 Charging the Battery Pack

The gage operates for at least 25 hours between charges under normal conditions (4Hzmeasure update rate in Mode 1 with the Backlight turned off.) The current battery status is

always indicated in the lower right corner of the gage display. This indicator shows apercentage of the battery charge remaining. The maximum percentage that can bedisplayed is 99%. (See Monitoring the Battery Charge on page 30.)

When the battery is insufficiently charged, the gage automatically powers off to preventdamage to the battery. Recharge the battery using the Model 36CA PLUS charger.

To charge the NiCad battery pack, plug the 36CA PLUS AC Charger Adapter into anappropriate source of AC power, and plug the cable from the Charger/Adapter into thecharger socket on the top of the gage. The battery recharges whether the gage is OFF orON. Do not attempt to use the battery charge indicator to determine when batterieshave reached full charge. For a fully discharged battery, allow approximately 2 hours tofully recharge. You can use the gage for normal measurements while the Charger/ACAdapter is connected with little effect on the recharge time.

2.7 Replacing the Battery Pack

After several hundred recharges, the NiCad batteries lose the ability to hold a full charge.

To replace an old battery pack, follow these steps:




910-232B 31

1. Open the battery panel on the back of the gage case by loosening the four captivescrews.

2. Remove the battery, once the case is open, by gently pulling the black strap at the rightend of the battery.

3. Remove the plug that connects the wire from the battery pack to the circuit board ofthe gage.

4. Connect the new battery pack, and install with the label side facing outward.

5. Replace the battery panel and tighten the screws.

Note: The internal memory is maintained for over an hour when the battery isremoved. If a new battery is installed in less than an hour, no calibration orthickness data is lost.

2.8 Using AA Batteries

Non-rechargeable alkaline batteries are available for use with the Model 25HP PLUS.

To replace the NiCad Rechargeable batteries with alkaline batteries, follow these steps:

1. Remove the NiCad pack.

2. Insert 6 “AA” Alkaline batteries into provided alkaline battery holder.

3. Connect the Alkaline battery holder to the gage using the same connector as theNiCad.

4. Place the Alkaline holder into battery compartment.

5. Replace the battery panel and tighten screws.

Note: It is also possible to charge the Nicad battery outside of the Model 25HPPLUS using a special external battery charger adapter. Contact Panametrics-NDTTM for more information on external battery charging.

2.9 Discussing Theory of Operation (Standard MeasureType)

The Model 25HP PLUS operates on the “Pulse/Echo” principle. This principle works byprecisely timing the reflection of high frequency sound waves from the transducer to thefar wall of a test piece. This technique, derived from sonar, has been widely applied tonondestructive testing because it permits accurate measurement of material thicknesseven though access may be available from only one side.

The Model 25HP PLUS uses a variety of piezoelectric transducers that generate bursts ofmechanical vibrations, or sound waves, when excited by short electrical pulses. Thefrequency of these sound waves is far beyond the limit of human hearing; from one million



32 Model 25HP PLUS

to twenty million cycles per second, versus a typical limit of less than twenty thousandcycles per second for the human ear. Sound at these very high frequencies does not travelwell through air, so a coupling medium such as a drop of liquid (usually propylene glycol,glycerin, water, or oil) is used between the transducer and the test piece.

The sound waves generated by the transducer are coupled into the test piece and reflectedback from the opposite side. The same transducer then receives the reflected sound wavesand converts them into electrical pulses. The gage amplifies the received signal, digitizesa selected portion of the wavetrain, and then very precisely measures a time intervalcorresponding to one round trip of the sound waves in the test piece. This measurement ismade in one of three modes as described below. The gage, which has been calibrated to thespeed of sound in the test material, computes the thickness of the test material using therelationship:

The Model 25HP PLUS can employ any of three measurement modes to calculate pulsetransit time.

Mode 1: Use with contact transducers. In this mode, measurement is made from the initialexcitation pulse to the first returning echo from the backwall of the test piece. The “MTI”marker indicates the Measured Time Interval.

Mode 2: Use with delay line and immersion transducers. In this mode, measurement ismade between an interface echo marking the time the sound wave enters the test piece andthe first backwall echo. The “MTI” marker indicates the Measured Time Interval.

Mode 3: Use with delay line and immersion transducers. In this mode, measurement ismade between two successive backwall echoes that follow an interface echo. The “MTI”Marker indicates the Measured Time Interval.

x = the thickness of the material

Figure 4 Model 25HP PLUS Block Diagram

The figure above is a block diagram of the Model 25HP PLUS. The pulser, under thecontrol of the microprocessor, provides a unidirectional broadband spike voltage impulse

to a heavily damped broadband ultrasonic transducer. The broadband ultrasonic pulsegenerated by the transducer is coupled to the test piece by means of liquid couplant.Echoes returning from the back or inside surface of the test piece are received by thetransducer and converted to electrical signals, which in turn are fed to the receiver AGCamplifier. The microprocessor-based control and timing logic circuits both synchronizethe pulser and select the appropriate echo signals that will be used for the time intervalmeasurement.

If echoes are not detected during a given measurement period, the gage will shut down tosave power until a new measurement cycle is required. If echoes are detected, the timingcircuit will precisely measure an interval appropriate for the selected Measurement mode, and then repeat this process a number of times to obtain a stable, averaged reading.The microprocessor then uses this time interval measurement, along with sound velocityand zero offset information stored in the Random Access Memory (RAM), to calculatethickness. Finally, the thickness is shown on the LCD and updated at a selected rate.

2.10 Factors Affecting Performance and Accuracy

• Calibration: The accuracy of any ultrasonic measurement is only as good as theaccuracy and care with which the gage is calibrated. The gage is shipped from thefactory with standard setups for a number of transducers and applications. In somecases, it is desirable to optimize these setups for specific measurement situations, asdescribed in Chapter 3. In all cases, it is essential that the velocity and zerocalibrations, described in Chapter 3, are performed whenever the test material ortransducer is changed. Periodic checks with samples of known thickness arerecommended to verify that the gage is operating properly.

• Surface Roughness of the Test Piece: The best measurement accuracy is obtainedwhen both the front and back surfaces of the test piece are smooth. If the contactsurface is rough, the minimum thickness that can be measured will increase because of sound reverberating in the increased thickness of the couplant layer. Additionally, if either surface of the test piece is rough, the returning echo may be distorted due to themultiplicity of slightly different sound paths seen by the transducer, and measurementinaccuracies will result.

• Coupling Technique: In Mode 1 (contact transducer) measurements, the couplantlayer thickness is part of the measurement and is compensated by a portion of the zero

offset. If maximum accuracy is to be achieved, the coupling technique must beconsistent. This is accomplished by using a couplant of reasonably low viscosity,employing only enough couplant to achieve a reasonable reading, and applying thetransducer with uniform pressure. A little practice shows the degree of moderate tofirm pressure that produces repeatable readings. In general, smaller diametertransducers require less coupling force to squeeze out the excess couplant than largerdiameter transducers.

In all modes, tilting the transducer distorts echoes and cause inaccurate readings, asnoted below.

• Curvature of the Test Piece: A related issue involves the alignment of the transducerwith respect to the test piece. When measuring on curved surfaces, it is important toplace the transducer approximately on the centerline of the part and held as nearly

normal to the surface as possible. In some cases, a spring-loaded V-block holder ishelpful for maintaining this alignment. In general, as the radius of curvaturedecreases, the size of the transducer is reduced, and the more critical transduceralignment becomes. For very small radiuses, an immersion approach is necessary. Insome cases, it is useful to observe the waveform display via the PC Scope option as anaid in maintaining optimum alignment. Practice with the aid of a waveform displayprovides the operator a proper “feel” for the best way to hold the transducer.




910-232B 35

On curved surfaces, it is important to use only enough couplant to obtain a reading.Excess couplant forms a fillet between the transducer and the test surface where soundreverberates and possibly creates spurious signals that can trigger false readings.

• Taper or eccentricity: If the contact surface and back surface of the test piece are

tapered or eccentric with respect to each other, the return echo will be distorted due tothe variation in sound path across the width of the beam. Accuracy of measurement isreduced. In severe cases, no measurement is possible.

• Acoustic Properties of the Test Material: There are several conditions found incertain engineering materials that can potentially limit the accuracy and range of ultrasonic thickness measurements:

– Sound Scattering: In materials such as cast stainless steel, cast iron, fiberglass,and composites, sound energy will be scattered from individual crystallites in thecasting or boundaries of dissimilar materials within the fiberglass or composite.Porosity in any material can have the same effect. Gage sensitivity must beadjusted to prevent detection of these spurious scatter echoes. This compensationcan in turn limit the ability to discriminate a valid return echo from the back side

of the material, thereby restricting measurement range.

– Sound Attenuation or Absorption: In many organic materials such as low densityplastics and rubbers, sound energy is attenuated very rapidly at the frequenciesused for ultrasonic gaging. This attenuation typically increases with temperature.The maximum thickness that can be measured in these materials are often limitedby attenuation.

– Velocity Variations: An ultrasonic thickness measurement is accurate only to thedegree that material sound velocity is consistent with gage calibration. Somematerials exhibit significant variations in sound velocity from point to point. Thishappens in certain cast metals due to the changes in grain structure that result fromvaried cooling rates, and the anisotropy of sound velocity with respect to grainstructure. Fiberglass can show localized velocity variations due to changes in theresin/fiber ratio. Many plastics and rubbers show a rapid change in sound velocitywith temperature, requiring that velocity calibration be performed at thetemperature where measurements are made.

• Phase Reversal or Phase Distortion: The phase or polarity of a returning echo isdetermined by the relative acoustic impedances (density x velocity) of the boundarymaterials. The gage assumes the customary situation where the test piece is backed byair or a liquid, both of which have lower acoustic impedances than metals, ceramics,or plastics. However, in some specialized cases (such as measurement of glass orplastic liners over metal, or copper cladding over steel) this impedance relationship isreversed, and the echo appears phase reversed. In these cases, it is necessary to changethe appropriate Echo Detection polarity, as discussed in Chapter 3, in order tomaintain accuracy.



36 Model 25HP PLUS

Figure 5 Usual Case

Figure 6 Special Case

A more complex situation can occur in anisotropic or inhomogeneous materials suchas coarse-grain metal castings or certain composites, where material conditions resultin the existence of multiple sound paths within the beam area. In these cases, phasedistortion can create an echo that is neither cleanly positive nor negative. Carefulexperimentation with reference standards is necessary, in these cases, to determineeffects on measurement accuracy.

3.4 Performing a Quick Setup

Normally, custom application setups are changed by selecting the application setup listusing [RECALL SETUP]. Slew down to the desired setup name and press [MEAS]. This

process is adequate for typical setups that are changed infrequently. However, when it isnecessary to change frequently between two or more custom setups, a more direct short-cut procedure is available, known as Quick Setup.

When this Quick Setup procedure is activated, a single keystroke (held for a moment toprevent errors) quickly switches to any of the first nine custom setups.

To activate the Quick Setup feature, follow these steps:

1. Press [2nd F], [0] (SP Mode).

2. Press [ ], [ ], or [ENTER] to select Measurement.

3. Press [ ] or [ ] to select Quick Setup.

4. Press [ ] or [ ] to select On or OFF.5. Press [MEAS] to return to Measure mode.

To change the active application setup to any of the first nine custom setups when QuickSetup is activated, follow these steps:

1. Press and hold any numeric key [1] through [9] until the beep sounds (about 1 1/2seconds). The momentary message USER N is now active and is displayed on the firststatus line, and the active setup is changed to the displayed name.

Note: USER-N refers to the Nth custom setup where N is the numeric key pressed.

2. Numeric keys may be used repeatedly in this way to quickly move between setups.When preceded by the [2nd F] key, numeric keys always perform the indicatedsecond function, e.g. [2nd F], [5] selects MIN or MAX Measure mode even whenQuick Setup is activated. Quick Setup remains enabled until turned off by followingthe procedure described in step 1 above.

3.5 Using Auto Zero and the M2008

The M2008 transducer is a special low frequency transducer used to measure thick FRPand composite materials. The 25HP PLUS uses a special Auto Zero feature when usingthis transducer. This feature allows the gage to automatically adjust the Zero offset valueto compensate for any temperature changes in the delay line of the M2008. When usingthe M2008 transducer, it is necessary to periodically reset the zero calibration, especialwhen the temperature of the material or delay line changes.

Note: This function only operates with the M2008 setup.



44 Model 25HP PLUS

To use the M2008, follow these steps:

1. Recall the DEFP1-0.5/2008 default transducer setup or any custom setup that uses theM2008 transducer by pressing the [RECALL SETUP] key and then press [ ] or [ ]to highlight the setup.

2. Press [MEAS]. The gage displays the following message:

Figure 13 Recall Setup Message

3. Verify the probe is uncoupled from the material and free of couplant. Press [ZERO]. The gage displays a zero offset number and enter the measure mode.

Note: Press [ZERO] at any time to Auto adjust the Zero Off Set and compensatefor temperature changes in the delay line.

Once the transducer is zeroed, you can perform a Cal Velocity and Cal Zero.

3.6 Calibrating the Model 25HP PLUS (ThicknessMeasurement Mode)

Calibration is the process of adjusting the gage, prior to testing, to a known reference valuefor a specific material and transducer. Calibrating the gage is always necessary beforemeasuring specific material by one of the methods described below. Remember, thegage’s measurement accuracy is only as good as the calibration that is performed.

The Model 25HP PLUS calibration procedure falls into one of the following threecategories:

• Velocity and Zero Calibration

• Velocity Calibration Only

• Zero Calibration Only




910-232B 45

Note: In sections 3.5.1–3.5.3, the following notes are applicable:

Caution: Save all changes made to Active Setups. Unsaved data will be lost when adifferent application setup is recalled.

3.6.1 Velocity and Zero Calibration (Thickness Measurement Mode)

Velocity and Zero Calibration find both sound velocity and zero offset when you do notknow either of these elements. This calibration process requires two pieces of test materialof known thickness values, which are within the measurement range of both thetransducer and setup specifications. See Table 12 on page 178 for more information.

One of the test materials must be thicker than the other. The thicker piece, used to measure

velocity, should be equal to or greater than the upper range of thickness to be measured.The thinner piece, used for the zero offset, should be equal to or less than the lower rangeof minimum thickness to be measured.

To calibrate for the thickness range represented by these test samples, follow these steps:

1. Power on the gage and wait for the Measure screen display.

2. Place a drop of couplant on the surface of the thicker material sample, and couple thetransducer to the sample using moderate to firm pressure. A thickness reading appearson the display while the LOS prompt in the upper right corner of the displaydisappears.

3. Press [CAL] when a stable reading is on the display and the LOS prompt is not on the

screen. Observe the CAL (calibration) prompt on the display.4. Remain coupled to the standard test piece and ensure that there is still a stable reading

on the display. Press [VEL]. A prompt appears on the display: “Enter value for thickstandard”.

5. Remove the transducer from the sample. The thickness value remains on the display.

6. Using the numeric keys on the gage, enter the actual known thickness of the testmaterial.

· If a mistake is made or any problem is experienced during the calibration,press [MEAS] and return to Step 1.

· After completing Step 2, if the prompt CAL LOCK appears on thebottom of the display instead of CAL, then unlock the calibration byfollowing the steps below:

- Press the [MEAS] key.

- Press the [6] and [3] keys simultaneously.

- The gage will beep and display a message, CAL LOCK is off at the bottom of the gage.

- Repeat steps 1 and 2.



46 Model 25HP PLUS

Continue with the following steps:

1. Put a drop of couplant onto the thin material sample and couple the transducer to it

using moderate to firm pressure.2. Press [CAL]. A thickness reading appears on the display.

3. Remain coupled to the test piece and ensure that there is a stable reading on thedisplay. Press [ZERO]. A prompt appears on the display: “Enter value for thissample”.


5. Using the numeric keys, enter the actual known thickness of the test material.

6. Press [MEAS] to finalize the calibration.

Note: You can Lock the calibrated readings to ensure that it is not accidentally

changed. (Refer to Section 4.1.8–Calibration Lock.) From the Measuremode, press [3] and [6] simultaneously. The gage displays a message: “CALLOCK is on...”

3.6.2 Velocity Calibration Only (Thickness Measurement Mode)

Use the Velocity Calibration Only procedure when the gage is calibrated for a particulartransducer/material combination, and that same transducer is used with a differentmaterial and sound velocity. The procedure requires test material of known thickness,equal to or greater than the upper range of thickness to be measured.

To calibrate for the thickness range represented by this test sample, follow these steps:


2. Place a drop of couplant on the surface of the test material, and couple the transducerto the sample using moderate to firm pressure. A thickness reading appears on thedisplay while the LOS prompt in the upper right corner of the display disappears.

3. Press [CAL] when a stable reading is on the display and the LOS prompt is off. Thegage displays a message: “Couple to standard; press VEL or ZERO”.

4. Remain coupled to the test piece and ensure that there is still a stable reading on thedisplay. Press [VEL]. A prompt appears on the display: “Enter value for thickstandard”.


6. Use the numeric keys to enter the actual known thickness of the sample beingmeasured.

7. Press [MEAS] to finalize calibration.

Note: You can “LOCK” the calibrated readings to ensure that it is not accidentallychanged. (See Managing the Calibration Lock on page 68.) From the




910-232B 47

Measure mode, press [3] and [6] simultaneously. The gage displays amessage: “CAL LOCK is on...”

If the sound velocity of the test material is known, then enter the velocity directly.

To enter a known velocity, follow these steps:

1. Turn the gage on and wait for the Measure screen.

2. Press [VEL]. The Velocity prompt appears and the gage displays the current soundvelocity.

3. Use the numeric keys to enter the new velocity.

4. Press [MEAS].

3.6.3 Zero Calibration Only (Thickness Measurement Mode)

Use the Zero Calibration Only procedure when the gage is calibrated for a particulartransducer/material combination, but the transducer is replaced and the test materialremains the same.

Note: See Choosing a Default or User-Defined Setup on page 40 if a transducer ischanged to a different type of transducer after calibrating. See Performing aQuick Setup on page 43 to repeat this procedure.

The Zero Calibration Only procedure requires test material of known thickness,preferably near the lower end of the desired measurement range, but not below the gage’sminimum measurement range for both the transducer and setup specifications.

To calibrate for the thickness range represented by this test sample, follow these steps:


2. Place a drop of couplant on the surface of the material sample, and couple thetransducer to the sample using moderate to firm pressure. A thickness reading appearson the display while the LOS prompt in the upper right corner of the displaydisappears.

3. When a stable reading is on the display and the LOS prompt is off, press [CAL]. Thegage displays a message: “Couple to standard; press VEL or ZERO”.

4. Remain coupled to the test piece and ensure that there is still a stable reading on thedisplay. Press [ZERO]. A prompt appears on the display: “Enter value for thinstandard”.


6. Use the numeric keys to enter the actual known thickness of the sample beingmeasured.

7. Press [MEAS] to finalize the calibration.

Note: You can “LOCK” the calibrated readings to ensure that it is not accidentallychanged. (See Managing the Calibration Lock on page 68.) From the



48 Model 25HP PLUS

Measure mode, press [3] and [6] simultaneously. The gage displays amessage: “CAL LOCK is on...”

If you know the zero offset number for a particular transducer, enter it directly. See

Velocity and Zero Calibration (Thickness Measurement Mode) on page 45 to determinethe zero number for a given transducer and calibrate the gage according to the procedure(See Zero Calibration Only (Thickness Measurement Mode) on page 47 also.) Press[ZERO] to read the zero offset number. Record this number for each probe for futurereference.

Note: You must use the same transducer cable lengths in order to maintainaccuracy of the zero offset number recorded for each probe. This rule isespecially true when using cable lengths over 10 ft. (approximately 3Meters) in 0.0001" or 0.001mm resolution.

To enter a known zero offset number, follow these steps:


2. Press [ZERO]. The gage displays the prompt: “Enter value for zero”. The gagedisplays the zero offset number to which it is presently calibrated.

3. Use the numeric keys to enter the new zero offset.

4. Press [MEAS] to enter the new zero offset into the gage.

3.6.3.1 Perform a Single Point Calibration in Velocity or Time of Flight Mode

This calibration procedure should not be used if the gage is set to Thickness Measurementtype. A one point calibration requires a Reference Standard with a known mechanical

Thickness and Sound Velocity.To perform a single point calibration, follow these steps:

1. Recall the desired Default or custom transducer setup. (See Choosing a Default orUser-Defined Setup on page 40.)

2. Press [VEL/THICK]and enter the known velocity of the reference standard using thenumeric keys. Press [MEAS].

3. Couple to the Reference of standard. Press [CAL] when you are getting a steadythickness reading.

4. Press [VEL/THICK] or [ZERO/THIN], and enter the known thickness of thestandard using the numeric keys.

5. Press [MEAS] to complete the calibration.

3.6.3.2 Perform a Two Point Calibration in Velocity or Time of Flight Mode

A two point calibration requires two reference standards or the same material velocitywith known thickness. The velocity value does not need to be known.

To perform a two point calibration, follow these steps:




910-232B 49

1. Recall the desired default or custom transducer setup. (See Choosing a Default orUser-Defined Setup on page 40.)

2. Couple to the thick reference standards and press [CAL].

3. Press [VEL/THICK] when the thickness reading becomes stable.

4. Uncouple the transducer from the material and enter the know thickness of thereference standard using the numeric keys.

5. Couple to the thin reference standard and press [CAL].

6. Press [ZERO/THIN] when the thickness reading becomes stable.

7. Uncouple the transducer from the material and enter the know thickness of thereference standard using the numeric keys.

8. Press [MEAS] to complete the calibration.

3.6.3.3 Making Thickness Measurements (Thickness Measurement Mode)

To make thickness measurements, follow these steps:

1. Verify the 25HP PLUS is in Thickness Measurement mode. (See SelectingMeasurement Types on page 39.)

2. Perform both the Cal Velocity and Cal Zero procedure. (See Velocity and ZeroCalibration (Thickness Measurement Mode) on page 45.)

3. Apply couplant to the measurement location and couple the transducer to the sampleand the thickness should be shown on the display.

3.6.3.4 Making Velocity Measurements (Velocity Measurement Mode)

The gage displays the material Velocity.



50 Model 25HP PLUS

3.6.3.5 Making Velocity Measurements with Optional Digital Caliper

In order to make Velocity measurements, the mechanical thickness of the material beingmeasured must be input in to the Model 25HP PLUS. This thickness is known as the REFValue. An optional HPV/C Digital Caliper and HPP/CC interface cable allows the Model25HP PLUS to receive this REF (reference) thickness directly from a digital caliper.Measure the mechanical thickness with the digital caliper and press the Set key, and theREF thickness automatically updates to the new value; this makes it fast and easy tomeasure the sound velocity of material with varying thickness.

Perform the following four procedures using the HPV/C Digital Caliper with the Model25HP PLUS

To make a cable connection, follow these steps:

1. Remove the RS232 environmental plug from the caliper. The plug is located in theRS232 port above the Fowler Sylvac label on the caliper.

2. Insert the HPP/CC cable into the caliper’s RS232 slot with the words OPTO RS 232

facing down.

3. Plug the other end of the HPP/CC cable into the RS232 port of the 25HP PLUS .

To set up the units on the HPV/C Digital Caliper, follow these steps:

1. Press the Set button or Mode button to power on the digital caliper.

Note: To power off the caliper press and hold the Set button for 2 seconds.

2. Press the Mode button. SET is displayed (active for 3 seconds.)

3. Press the Mode button twice. UNIT is displayed (active for 3 seconds.)

4. Press the Set button to toggle between Inch and MM.

To set up the 25HP PLUS Velocity/Thickness gage, follow these steps:

1. Power on the 25HP PLUS.

2. Press [2ndF],[0] (SP Mode).

3. Press [ ] or [ ] to highlight the Measurement option. Press [ENTER].

4. Press [ ] or [ ] to highlight the Meas Type option.

5. Press [ ] or[ ] to set the mode to VEL.

Note: The digital caliper only works when the gage is in Velocity mode.

6. Press [Meas].

7. Press [2ndF],[0] (SP Mode).

8. Press [ ] or [ ] to highlight the Communication option. Press [ENTER].




910-232B 51

9. Press [ ] or [ ] to highlight the Caliper Setting option.

10. Press [ ] or[ ] to select the On option.

Note: The digital caliper only works when the communication is set to Calipermode.

11. Press [Meas].

12. Calibrate the gage.

To send the digital caliper Thickness Reading to the Model 25HP PLUS, follow thesesteps:

1. Use the digital caliper to measure the thickness of the material.

2. Press the Set button. The displayed thickness value is transferred to the Model 25HP

PLUS and is displayed in the REF VALUE Box.3. Couple the transducer to the location that was mechanically measured and the gage

displays the velocity of the material.

3.6.3.6 Making Time of Flight (TOF) Measurements

To make TOF measurements, follow these steps:

1. Verify the 25HP PLUS is in Velocity Measurement mode. (See SelectingMeasurement Types on page 39.)

2. Perform either a one point or two point calibration.

3. Apply couplant to the measurement location and couple the transducer to the sampleand the Time of Flight should be shown on the display.

3.7 Adjusting the Range

The range of the waveform display is the distance spanned by the horizontal axis of thedisplay in the non Zoom mode. (See Operating the Zoom Mode on page 53.) The left endof the horizontal-axis is always zero thickness, and the right end is the thicknessrepresenting the endpoint of the range unless the delay was adjusted. There are fixedranges available for each transducer frequency. The available ranges are also materialvelocity dependent; for steel they are:

.500 in (10.0mm)

1.00 in (20.0mm)

2.00 in (50.0mm)

5.00 in (100.0mm)

10.00 in (200.0mm)



52 Model 25HP PLUS

20.00 in (508.0mm)

25.00 in (635.0mm)

40.00 in (1016.0mm) Thru-Transmission only

50.00 in (1270.0mm) Thru-Transmission onlyThese selectable ranges let you adjust the thickness span of the waveform display toencompass only the thickness range being measured and thus obtain maximum waveformresolution for each application. The range setting affects the waveform display only. Youcan still make measurements even when the display range does not encompass thethickness being measured.

To change the range at any time the display is active, follow these steps:

1. Press [RANGE]. The waveform range changes to the next higher available range.

2. Continue to press [RANGE] until the desired range is obtained. The range valuerecycles to the minimum range value following the maximum range value.

Tip: Press [ ] prior to pressing [RANGE] to either increase or decrease therange direction. You can change the range direction back to increasingvalues by pressing [ ] prior to pressing [RANGE] again.

3.8 Operating the Delay Function

The Range Delay of the waveform display adjusts the beginning of the horizontal span inthe non Zoom mode. The left end of the horizontal-axis is normally set to zero thickness.The Delay function allows you to adjust the left end of the horizontal axis so the waveform

can be centred over a portion of the waveform that occurs later in time. This function isvery useful when using delay line or immersion transducers or when measuring thickmaterial so that the measured echoes can be seen in greater detail.

To operate the Delay function, follow these steps:

1. Press [2ndF], [Range] (DELAY).

2. Press [ ] or [ ] to adjust the waveform Delay.




910-232B 53

Figure 14 Displaying the Waveform Delay

3.9 Operating the Zoom Mode

The Zoom mode allows the thickness region surrounding the measured echoes to expandto full screen width. The resulting zoomed waveform depends on the Measurement modethat the gage is using. The zoom adjusts the Range and Delay so the measured echoes areon screen are shown in the greatest detail. The Zoom mode also tracks the measuredechoes adjusting the Range and Delay automatically, always keeping the measuredechoes on the waveform screen.

3.9.1 Zoom in Mode 1

Zoom in Mode 1 centers the first Backwall echo on the screen.

Figure 15 Comparing Normal Display to Zoom in Mode 1


Zoom in Mode 2 adjusts the Waveform Range and Delay so that the Interface Echo andFirst Backwall echo are shown on the Waveform screen.




54 Model 25HP PLUS

Note: In the Zoom mode, the gage automatically adjusts the Range and Delay totrack the Interface and first Backwall echo. If you adjust the Range, the gageremains at the selected Range and automatically adjusts the Delay to track the Interface Echo.


Zoom in Mode 3 adjusts the Waveform Range and Delay so that the Interface Echo andSecond Measured Backwall echoes are shown on the Waveform screen.


Note: In Zoom mode, the gage automatically adjusts the Range and Delay to track the Interface and second Backwall echo. If you adjust the Range, the gageremains at the selected Range and automatically adjusts the Delay to track the Interface Echo.

3.10 Using the Backlight

The display has the greatest contrast when viewed in bright light. However, it is easilyreadable in subdued light or even complete darkness by using the built-in backlight.

To activate the backlight, press the orange key with the lightbulb symbol. Deactivate thebacklight by pressing the lightbulb key again. See Managing the Backlight on page 72 formore information.

Note: Use the backlight only when needed because it drains the battery about threetimes faster when activated.

4 Managing Special Gage Functions andSP Modes

This chapter describes how to operate the Model 25HP PLUS using special functions andmodes.


• Operating Gage Functions

• Operating SP Modes

• Saving Key Selection

4.1 Operating Gage Functions

The Model 25HP PLUS has many thickness measurement features. Although the featuresoutlined in this section are not required for basic thickness operation, they can make thegage a more powerful, versatile instrument.

4.1.1 Selecting a Differential Mode

The Model 25HP PLUS has two Differential modes

• Normal Differential

• Percent Ratio

Normal Differential: Shows the actual thickness along with the difference between theactual thickness measurement and a user set reference value.

[(Normal Differential) = (Actual Thickness) – (Differential Reference Value)]

The actual thickness appears on the thickness display and the differential thicknessappears in the differential display area. See the following figure:



58 Model 25HP PLUS

Figure 18 Normal Differential Mode

Percent Ratio: Shows the actual thickness along with the percent difference from a userset reference value.

[(Percent Ratio)] = [(Actual Thickness) - (Differential Reference Value)] /(DifferentialReference Value)]*(100)

The actual thickness appears on the thickness display and the Percent Ratio thicknessappears in the differential display area as shown below:

Figure 19 Percent Ratio Differential Mode

4.1.2 Using the Measurement Display Update Rate

The Measurement Display Update Rate is the rate that the measured thickness value andwaveforms are updated on the display, which can be adjusted between 4, 8, 12, 16, 20measurements per second. Some of the update rates allow averaging without QBAR (seenote below), and averaging with QBAR. The default measurement rate is 4 measurementsper second.

Differential Value

Active Thickness

Percent Differential

Actual Value




910-232B 59

Note: Averaging is used for the highest degree of accuracy/stability. A fivemeasurement running average is calculated and displayed at the selectedmeasurement update rate.

The QBAR (quality bar), is an indicator of measurement stability shown tothe right of the thickness value. The length of the QBAR is proportional tothe measurement stability. A short QBAR indicates relatively unstablereadings that vary from one to the next. A long QBAR indicates stablereadings, that is, readings that do not vary from one another. Averaging withQBAR aids in finding optimum transducer coupling in some applications.

A combination of the measured material, measurement rate setting, resolution selected,transducer being used, speed of placement, and movement of the transducer affect howfast the least significant digit of the thickness value changes. In general, you should use ameasurement rate and technique that yields fast response to transducer placement andmovement without encountering distracting “jitter” of the least significant digit.

The current display update rate is near the bottom left in the thickness measurement box.

Figure 20 Displaying the Measurement Update Rate

To change the measurement rate, follow these steps:

1. Press [2nd F], [4] (MEAS RATE).

2. Press [ ] or [ ] to select the desired rate. The available setting are:

4Hz 16Hz Averaging

8Hz 16Hz Averaging QBAR

12Hz 20Hz Averaging

16Hz 20Hz Averaging QBAR20Hz

3. Press [MEAS] to return to the Measure mode using the new measure rate.

Update Rate 4Hz



60 Model 25HP PLUS

Note: When Min or Max Measure is selected, the Measure Rate is temporarilyforced to “20/sec.” When the Min or Max mode is exited, the Measure Rateis restored to its previous value.

4.1.3 Using the Minimum Thickness Mode

The Minimum mode displays the smallest thickness measured since theMinimum modewas selected or since it was reset. The Minimum mode is useful when it is important todetermine the thinnest reading obtained while making a series of readings on a test piece.The fastest display update rate is automatically activated when entering the Minimum mode. When leaving the Minimum mode, the display update rate is restored to itsprevious state.

The current thickness is displayed in the main thickness display and the minimum isdisplayed in the Min thickness area.

Figure 21 Displaying the Minimum Thickness

Note: In some situations, you can capture a false minimum reading when thetransducer is lifted from the test piece. This is possible when using excess

couplant, particularly on smooth surfaces, causing the gage to read thethickness of a couplant drop as the transducer is lifted. To avoid thisproblem, use the Freeze function in conjunction with the MinimumThickness mode to freeze the waveform prior to uncoupling the transducer.Once the transducer is uncoupled and free of couplant, press [FREEZE]again to unfreeze the display and recall the minimum thickness andwaveform.

To select a Min Measure mode from the Measure, Differential Measure, or AlarmMeasure mode, follow these steps:

1. Press [2ndF], [5] (MIN/MAX). The MIN thickness displays only when the gage is ina Min Measure mode.

2. Press [MEAS] to reset the held minimum value so that the minimum for a new seriesof measurements can be found.

The thickness display will blank indicating that the old minimum value is reset.Saving or sending a minimum reading also resets the minimum value.

3. Press [2ndF], [5] (MIN/MAX) twice to exit from a Min Measure mode and return tothe Measure, Differential Measure, or Alarm Measure mode.

Note: The [2nd F], [5] (MIN/MAX) cycles from Measure, to Min Measure, to MaxMeasure, and back to Measure, etc.

4.1.4 Using the Maximum Thickness Mode

The Maximum mode displays the greatest thickness measured since the Maximum modewas selected or since it was reset. The Maximum mode is useful when it is important todetermine the Maximum thickness reading obtained while making a series of readings ona test piece. The fastest display update rate is automatically selected when entering theMaximum mode. When leaving the Maximum mode the display update rate is restoredto its previous state.

The current thickness is displayed in the main thickness display and the maximumthickness is displayed in the Max thickness area. The Maximum thickness replaces themain thickness display when the transducer is uncoupled or a (LOS) Loss of Signal

occurs.

62 Model 25HP PLUS

Note: In some situations, you can capture a false minimum reading when thetransducer is lifted from the test piece. This is possible when using excesscouplant, particularly on smooth surfaces, causing the gage to read thethickness of a couplant drop as the transducer is lifted. To avoid this

problem, use the Freeze function in conjunction with the MinimumThickness mode to freeze the waveform prior to uncoupling the transducer.Once the transducer is uncoupled and free of couplant, press [FREEZE]again to unfreeze the display and recall the minimum thickness andwaveform.

To select a Maximum Measure mode from the Measure, Differential Measure, orAlarm Measure mode, follow these steps:

1. Press [2ndF], [5] (MIN/MAX) twice. The Max thickness display shows when thegage is in a Max Measure mode and the thickness display shows the actual measuredthickness.

2. Press [MEAS] to reset the held Maximum value so that the Maximum for a new seriesof measurements can be found.

The thickness display will blank indicating that the old Maximum value is reset.Saving or sending a Maximum reading also resets the Maximum value.

3. Press [2ndF], [5] (MIN/MAX) to exit from a Max Measure mode and return to theMeasure, Differential Measure, or Alarm Measure mode.

Note: The [2nd F], [5] (MIN/MAX) cycles from Measure, to Min Measure, to MaxMeasure, and back to Measure, etc.

4.1.5 Managing High/Low Alarms

The Model 25HP PLUS has two different alarm modes: Standard Alarm and PreviousThickness Alarm. These alarms are audible beeps that warn you when measurements arebelow or above the alarm set points.

4.1.5.1 Activating the Standard Alarm

The Standard Alarm feature lets you view and change the Low Alarm Reference Value,High Alarm Reference Value, and to turn the visual and audible alarm functions ON/OFF.The Alarm Reference Values are thickness set points that have the current gage units andresolution. When an Alarm Measure mode is selected, the alarm condition occurs when

any displayed reading (either actual, minimum, or maximum) is either less than the LowAlarm Reference Value or greater than the High Alarm Reference Value.

The alarm condition is indicated by a flashing alarm flag located in the Thickness displayarea and a repeated audible beep as shown in the figure below:

4.1.6 Changing the Thickness Resolution

The resolution, i.e. the number of thickness value digits shown to the right of the decimalpoint, may be changed from the keyboard. This option may be useful in some applications

in which the extra precision of the last digit is not required, or where extremely roughoutside or inside surfaces make the last thickness display digit unreliable. The resolutionsare selectable; Standard (factory default) is 0.001" or 0.01mm; Low is 0.01" or 0.1mm.

• Standard (factory default): .001" or .01mm

• Low: .01" or .1mm

• High: .0001" or .001mm

The resolution selection affects all displays and data output of values with thickness units.This includes measured thickness, differential reference value, and alarm set points.

Note: The velocity is always reported with full five digit resolution.

To change the resolution while in the Measure mode, press [2ndF], [2] (RESOL). Thenew resolution is indicated by the position of the decimal point.

4.1.6.1 Velocity Resolution

The resolution, the number of digits shown to the right of the decimal point, can bechanged from the keyboard. This option is useful in some applications where the extraprecision of the last digit is not required. The resolution in velocity mode is selectable,standard 0.0001in/ µsec (00.001mm/ µsec), and low 0.001in/ µsec (00.01mm/ µsec).

4.1.6.2 Time of Flight ResolutionThe resolution, the number of digits shown to the right of the decimal point, is fixed at000.01µsec.

5 Using Custom Setups

In addition to providing programmed standard transducer setups, the Model 25HP PLUS

permits you to create custom setups by changing a series of pulser/receiver and gatingparameters. Use custom setups when the measurement requirements of a particularapplication are not optimally met by one of the standard setups. In some cases, a Model25HP PLUS ships from the factory pre-programmed with one or more custom setups tomeet special customer requirements. However, you may want to create your own customsetups. Once adjustments are made, you can name and store these setup parameters in oneof the 35 user defined setup locations. This feature gives the Model 25HP PLUS theflexibility to change quickly between transducer and application setups by selecting thesetup name from a stored list or using the Quick setup recall feature.

Note: The adjustments described in this section should be made only by a qualifiedtechnician who is familiar with the basic theory of ultrasonic gaging and theinterpretation of ultrasonic waveforms.

Many of these adjustments are interactive, and all of them have an effect on themeasurement range and/or measurement accuracy of the Model 25HP PLUS. In mostcases, do not attempt adjustments without monitoring waveforms. Additionally, whenestablishing a custom setup for a specific application, it is essential to verify performanceon reference standards representing the material(s) and thickness range to measure.

5.1 Managing the Detect Mode Function

The Detect Mode function selects Mode 1, Mode 2, or Mode 3 measurements. SeeDtectMode and EchWindow Parameters on page 91 for further explanation.

Mode 1: Measures the time of flight between the Main Bang and the first backwall echousing a direct contact transducer.

5.2 Defining a Setup Name

A user defined name has up to 16 alphanumeric characters used to name and describe thestored setup.

5.3 Defining a Probe Type

The probe type indicates the transducer type selected in the Active Setup. Each probe typeselected should match the frequency of the transducer being used for proper Pulser/

Receiver performance.

5.4 Varying Pulser Power Effects

You can adjust the excitation pulse (Main Bang) voltage in three steps of 30, 60, and 110Volts. Higher voltages may provide greater penetration at the expense of near surfaceresolution, especially in Mode 1, while lower voltages may provide better near surfaceresolution at the expense of penetration. For most applications the 110 Volt settingprovides the best signal-to-noise ratio for returning echoes. The Pulser Power does thefollowing:

• Indicates the voltage used to drive the transducer that is selected

• Affects the amount of energy going into the transducer and the size of the Initial Pulse

Figure 42 Pulser Power set to 110 Volts shows a larger initial pulse

5.5 Defining Maximum Gain

You can adjust the maximum available receiver gain from 0.0dB to 79.6dB. The Model25HP PLUS uses Automatic Gain Control (AGC) and Time Dependent Gain (TDG)functions to automatically adjust receiver gain to an optimum level when an echo isdetected. When no echo is detected (LOS prompt), the gain rises to the maximum level setby the Initial Gain, Slope, and Maximum Gain. If the maximum gain is set too high, thegage may hang up on transducer noise or other spurious signals; if it is set too low,returning echoes may not be high enough for detection.

In general, for a given application the Max Gain should be set high enough that all echoesof interest are detected, but a steady LOS prompt is displayed when the transducer is notcoupled to a test piece. The Max Gain indicates the Maximum (Time dependent) receivergain possible and is used to amplify echoes that are further out in time.

Note: The Max Gain can never be lower then initial Gain and has a maximum valueof 80.0dB.

Using Custom Setups

910-232B 89

Figure 43 Maximum Gain

5.6 Defining Initial Gain

Initial Gain and TDG Slope are part of a Time Dependent Gain system that may be used tooptimize near-surface resolution while providing a higher maximum gain for thicker

samples. You can adjust the Initial Gain from 0dB to the maximum defined by the MaxGain setting. This parameter sets an upper limit on receiver gain in the vicinity of theexcitation pulse (Mode 1) or interface echo (Modes 2 and 3). By effectively making theexcitation pulse or interface echo smaller, the TDG system permits detection of echoesoccurring close to pulse or echo in time.

The TDG system is also used in measurements of highly scattering materials, such as castmetals and fiberglass, to minimize detection of scatter echoes occurring ahead of thebackwall. From the initial gain level, receiver gain slopes up to the maximum gain level atthe rate determined by the TDG Slope setting. The Initial Gain setting is most critical inapplications where minimum thickness measurements must be optimized, and shouldalways be set with the aid of a reference standard representing that minimum. In caseswhere the minimum thickness capability is less important than penetration, and scatter

echoes are not a problem, Initial Gain can be set equal to Max Gain. The Initial Gain doesthe following:

• Indicates the initial (time dependent) receiver gain currently selected

• Amplifies echoes that are close to the Main Bang or interface echoes

• Starts at Time Zero and extends to:

– the Main Bang Blank in Mode 1

– the end of the Interface Blank in Mode 2 and 3

5.7 Defining TDG Slope

The Time Dependent Gain (TDG) Slope function controls the rate at which the receivergain slopes up from the Initial Gain level to the Max Gain level. You can set the Slope from

0.0 to 26.5dB per microsecond. Generally, TDG Slope should be set as high as possible toreach maximum gain as quickly as possible without having the gage hang up on spurioussignals.

• Rate of increase of the receiver (Time dependent) Gain from Initial Gain to Max Gain

• Slope helps suppress reflections from grain structure or fibers

• Slope adjusts from 0.0dB to 26.52 dB/µSec

• Point in time that the Gain starts to slope is:

– the Main Bang Blank in Mode 1

– the End of the Interface Blank in Mode 2 and 3

Figure 45 TDG Slope

5.8 Viewing the Main Bang Blank

The Main Bang Blank is effectively a blank zone that protects the receiver from falsereadings generated by the Main Bang. This blank or dead zone (up to 18 microsecondsfrom the excitation pulse) prevents you from detecting echoes of the trailing edge of theexcitation pulse as if it were a backwall or interface echo. The Main Bang Blank indicatesthe point in time where the gage begins to search for echoes.

In Modes 2 and 3, the setting of the Main Bang Blank is not critical; set at some pointbetween the end of excitation pulse ringdown and the interface echo.

In Mode 1, however, the length of the Main Bang Blank determines the minimumthickness that can be measured, and it must be positioned with care after selecting theInitial Gain level. In Mode 1, set just past the Initial Pulse. If the Main Bang Blank is tooshort, then the gage hangs up on the excitation pulse and readings are not be possible. If the

Main Bang Blank is too long, then the minimum measurable thickness is unnecessarilyrestricted. Make sure that the Main Bang Blank is always set before the interface echofrom the shortest water path when using immersion transducers.

In general, set the Main Bang Blank just beyond the point where the gage hangs up, andtest with the transducer both coupled to and uncoupled from the test material to ensureaccurate measurements.

5.9 Viewing the Echo Window

The Echo Window is the time interval in each Main Bang period during which the gage isenabled to detect Echoes. The Echo Window interval begins at the end of the Main BangBlank. The end of the Echo Window depends on the DtectMode and EchWindowparameters as shown in the following table:

Initial Pulse

DtectMode = 1 DtectMode = 2 or 3

Echo Window Starts: At end of Main BangBlank

At end of Main Blank

Table 8 DtectMode and EchWindow Parameters



92 Model 25HP PLUS

In Mode 1, the Echo Window can usually be set to any value greater than the round-trippulse transit time in the thickest or slowest piece of material to be measured. The exactsetting is not critical as long as it is long enough to include the farthest echo of interest. InModes 2 and 3, the Echo Window is limited to the time interval between successiveinterface echoes. The end of the Echo Window must be set ahead of the second interfaceecho to prevent an incorrect detection, which in turn determines a maximum measurable

thickness for Mode 2 and Mode 3 setups. In applications involving Mode 2 and Mode 3 immersion measurements, the echo placement must apply throughout the range of waterpaths to be used.

5.9.1 Managing the P/R Config

The 25HP PLUS has three different Pulser Receiver settings, Pulse echo, Thru-Transmission and Pitch Catch. Each of these setting is described below.

Pulse Echo: Is used with one single element transducer located on one side of thematerial. The same transducer is used to both send and receive the ultrasonic signal. PulseEcho is the most commonly used Pulser Receiver configuration and can be used in Mode1, 2 and 3.

Figure 50 Pulse Echo Configuration

Thru-Transmission: Is used with two single element transducer located on either side ofthe material. One transducer is used to send the ultrasonic signal and the other is used toreceive the ultrasonic signal. This Pulser Receiver configuration is most commonly usedon very attenuating materials were it is not possible for the ultrasonic sound energy to

make a round trip. Thru- Transmission is limited to mode1 measurements.

5.9.2 Echo 1 Detect and Echo 2 Detect

Echo 1 Detect and Echo 2 Detect select positive or negative polarity echo detection asdetermined by application requirements. Selection is dependant on mode of

measurement and type of test material.

Note: Positive and negative polarity refer to processed echoes displayed on thewaveform display.

Mode 1: Using contact transducers, Echo 1 is the backwall echo and Echo 2 is

not applicable. Echo 1 is normally negative, except when measuring materialof low acoustic impedance bonded to a material of high impedance (such asplastic or rubber over metal), where the echo is phase-reversed and positivedetection for Echo 1 is appropriate.

Mode 2: Using delay line or immersion transducers, Echo 1 is the interface

echo and Echo 2 is the backwall echo. Echo 1 is normally positive for highimpedance materials such as metals and ceramics, and negative for lowimpedance materials such as most plastics. Echo 2 is normally negative unlessthe backwall echo represents the sort of low-to-high impedance boundary

described above.

Mode 3: Using delay line or immersion transducers, Echo 1 is the interfaceecho and Echo 2 represents the backwall echoes. Since Mode 3 generally

involves measurement of high impedance materials, the general rule is to setEcho 1 positive and Echo 2 negative. In some special cases involving difficultgeometries, phase distortion may cause the positive side of the backwall echoes

to be better defined than the negative side; in such cases set Echo 2 positive.

Figure 54 Echo 1 Detection Negative



96 Model 25HP PLUS

Figure 55 Negative Detection Steel Back by Air

Figure 56 Positive Detection Plastic Bonded to Steel

5.9.3 Interface Blank

Use Interface Blank in Modes 2 and 3 only. Interface Blank represents a blank or deadzone up to 20 microseconds in length that follows the leading edge of the interface echo.In Mode 2, the Interface Blank prevents detection of trailing lobes or cycles of theinterface echo, which might otherwise be detected as backwall echoes, resulting in a hang-up condition.

The Interface Blank should be set as short as possible to avoid unnecessarily restrictingminimum measurable thickness. The Initial Gain function often helps reduce interfaceecho amplitude and permit use of a shorter interface blank. Check Interface Blank settingswith the transducer both coupled to and uncoupled from the test material.

In Mode 3, the Interface Blank selects which pair of backwall echoes are measured. Inmost conditions, the Interface Blank would be set just short of the first backwall echo.However, as a practical matter, the first backwall echo from thin materials is oftendistorted or lost in the interface ringdown, and with some challenging geometries (such astight radii) later pairs of backwall echoes may be cleaner than early ones. In these cases, setthe Interface Blank to a length that insures detection of a clean and well-defined pair ofbackwall echoes, even if echoes are not the first two.

5.9.4 Mode 3 Echo Blank

The function of Mode 3 Echo Blank in Mode 3 is analogous to that of Interface Blank inMode 2 or Main Bang Blank in Mode 1. This function creates a blank or dead zone up to

20 microseconds long following the leading edge of the first detected backwall echo, toprevent detection of trailing lobes or cycles of that echo and the resulting gage hang-up.Because Mode 3 Echo Blank limits minimum measurable thickness, set the controls asshort as possible; typically no longer than a few hundred nanoseconds. Special cases maybe an exception where mode conversion effects on curved samples cause significantspurious signals between legitimate echo peaks; in such cases set the Mode 3 Echo Blankas long as necessary to prevent detection of the spurious signals.

Managing the Datalogger

910-232B 101

6 Managing the Datalogger

Two very useful and powerful features of the Model 25HP PLUS are the internal

datalogger and the two-way serial communication (RS-232) interface. The operation ofthe Datalogger and data transmission are discussed in this section. (See Appendix C -Serial Interface on page 187 for more information.)

An optional Bar Code Wand is available. (See Appendix F - Accessories and ReplacementParts on page 221.) This bar code wand directs measurement location ID numbers into thegage by simply scanning bar code labels. The Bar Code Wand plugs directly into the gageI/O connector.

6.1 Understanding the Datalogger

The Model 25HP PLUS datalogger has an extensive built-in file and data managementsystem. Each thickness reading and/or waveform is stored and tagged with an

alphanumeric identification number and file name with descriptive fields. A completedescription of the measurement type, gage calibration and setup parameters is storedalong with each reading. The following are just a few datalogger functions:

• Store the waveform display with any thickness measurement

• Recall stored data to the gage displays, printed out, or sent to a computer

• Receive previously transmitted thickness and waveform data back from a computer



102 Model 25HP PLUS

• View current datalogger settings while simultaneously taking measurements as,shown below:

Figure 64 Identifying Datalogger Settings

You can store either thickness measurements only or thickness measurements with anassociated waveform. When each measurement is stored, the gage also stores a completedescription of the measurement conditions with the measurement. The additional datastored with each thickness value includes:

• File Name

• File Header Data

• Identifier

• Units (in or mm)

• LOS (Loss of Signal)

• Differential Mode

• Differential Reference Value

• Alarm Mode

• Alarm Status

• Alarm Set Points

• Minimum or Maximum Mode

• Minimum or Maximum Reading• Velocity

• Resolution

• Transducer Setup Number and Information

910-232B 103

When a waveform is stored, the following additional information is stored with it:

• Zoom Status

• Horizontal Axis Limits

• Detection Marker Position• Delay

• Range

• Rectification Mode

You can store a maximum of 18,000 thickness values without waveforms at any one timein the standard Model 25HP PLUS version. You can also store up to 1,700 thicknessvalues with waveforms. The memory is expandible in two increments of 1 MB each. Thefirst memory upgrade allows a maximum of 36,000 thickness values or 3,400 waveformswith thickness values. The second memory upgrade allows a maximum of 54,000thickness values or 5,100 waveforms with thickness values. Contact Panametrics-NDTTM for details about how to upgrade the memory.

6.2 Organizing the Datalogger

The Model 25HP PLUS datalogger is a flexible file based system. Every measurementstored into the datalogger is tagged with an file name and identification number (IDnumber). The file name and ID number may be thought of as the name of the place in thegage memory where the measurement data is stored. This description usually correspondsto the physical location numbers of each measurement point in the actual application. IDnumbers may also be associated with up to four Comments. The database can store a userdefined number of files with descriptive headers and each file has a user defined numberof identifiers.

When stored data is printed or loaded into a computer and later recalled back to the gage,each measurement is always uniquely identified by the file name and ID number where itwas initially stored.

6.2.1 File Name Structure

File names consist of up to eight alphanumeric characters. Allowable characters are asfollows:

0 1 2 3 4 5 6 7 8 9

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

- . #The total number of files is only limited by the number of identifiers. The file name islimited to eight DOS legal file name characters.

6.2.2 Identifier (ID Number) Structure

ID numbers consist of up to 16 alphanumeric characters. Allowable characters are asfollows:



104 Model 25HP PLUS

0 1 2 3 4 5 6 7 8 9


space - . / , : # *

The allowable number of ID numbers within a file is dependent on the total number ofidentifiers in the datalogger. There are no restrictions on the use of any allowed characterat any position in an ID number except that you cannot use a space as either the first or lastcharacter of the ID number.

6.2.3 File Name Header Structure

The file name header is a series of fields designed for additional descriptive informationpertaining to a file. These fields include the following:

File Description

Inspector ID

Location-Note

Each field in the header consists of from 0 to 32 alphanumeric characters. Allowablecharacters are as follows:

0 1 2 3 4 5 6 7 8 9


space - . / , : # *

here are no restrictions on the use of any allowed character at any position in a header fieldexcept that you cannot use a space as either the first or last character of the ID number.

The following screen shows the fields that are available in the header for usercustomization:

Figure 65 Creating a File Name

6.2.4 Comment Structure

Use Comments to annotate individual measurement sites in the database for unusualmeasurement conditions. Save these notes with or without the thickness measurementdata as a permanent record of conditions encountered at the time of the survey.




910-232B 105

Typical Comments are:

• THIN AREA

• THICK AREA

• OUT OF TOLERANCE• MIN THICKNESS

• MAX THICKNESS

• NO READING

• SEE WAVEFORM

A comment is a 16 character text note that can attach to a thickness reading in the database.The gage is capable of storing a maximum of 26 different comments per file, each ofwhich is identified by a comment code letter A, B, ...Z. Comments are user definable foreach file and can be alphanumeric. You can store 1 to 4 comments per thickness reading.Allowable characters are as follows:

0 1 2 3 4 5 6 7 8 9


space - . / , : # *

There are no restrictions on the use of any allowed character at any position in a commentexcept that you cannot use a space as either the first or last character of the ID number.

All comments stored with a reading appear as their associated letter code in the flagssection of the transmitted output. The full definition of each comment is written out in itsentirety in a comment table once transferred to a computer or printer.You can also viewComment code definitions on the gage display as shown below.

5. Highlight a file type and press [ENTER].

6.3.3.1 Incremental

After entering a starting ID number (up to 16 alphanumeric characters long) the gageautomatically increments to the subsequent ID numbers using the following incrementingrules:

• Only that portion of an ID number consisting of digits and letters (no punctuationmarks) beginning with the right-most character and extending leftward to the first

punctuation mark or to the left-most character (whichever comes first) can increment.• Digits are cycled 0, 1, 2, ..., 9, 0, etc. The 9 to 0 transition is done only after

incrementing the character to the left. Letters are cycled A, B, C, ..., Z, A, etc. The Z toA transition is done only after incrementing the character to the left. In either case, if there is no character to the left, or if the character to the left is a punctuation mark thenthe ID number cannot increment.

• If an ID number cannot increment, then after a reading is saved, an long error beepsounds and the momentary message “CANNOT INCREMENT” is shown on thewaveform display. Subsequent saves overwrite readings if you do not manuallychange the ID number first.

Note: To make the gage increment through a range of numbers several digits widewhile beginning with a single digit ID number, the maximum number of digit positions must be entered initially using leading zeroes. See Example 1.

6.3.3.4 2-D Matrix Grid

A grid is a sequence of ID numbers arranged to describe a path through a two-dimensionalor three-dimensional matrix. Each part of the ID number corresponds to a particularmatrix dimension.

A 2-D (two-dimensional) sequence begins with the ID number that refers to the firstcolumn and the first row. Then the column (or row) increments one value at a time until thesequence reaches the last column (or row) value while the other dimension value staysconstant. At this point the other dimension increments from its first to its last value. Thiscontinues until the ID number that refers to the last column and last row is reached. Note,either the columns or the rows can be selected to increment first. Refer to the followingfigure.

Figure 76 General Grid Database

How is a grid used? A grid structure may associate one dimension of the grid (e.g., thecolumns) with the physical parts whose wall thickness is to be measured. The particularmeasurement points on each part are then associated with the other dimension of the grid(e.g., the rows). See the following figure.



118 Model 25HP PLUS

Figure 77 One Grid for 75 Identical Parts

Alternatively, the rows and columns of a grid may refer to a two dimensional map ofmeasurement points on the surface of one part. In this case a different grid is made for eachpart. See the following figure.

6.3.3.6 3-D Matrix Grid

A 3-D Matrix Grid is a sequence of multi-part ID numbers arranged to describe a paththrough a three-dimensional matrix. Each part of the ID number corresponds to aparticular matrix dimension.

A 3-D (three-dimensional) sequence begins with the ID number that refers to the firstcolumn, the first row and the first point. Then the point (or column, or row) increments onevalue at a time until the sequence reaches the last point (or column, or row) value while theother two dimension values stay constant. At this point another dimension incrementsfrom its first to its last value. This continues until the ID number that refers to the lastcolumn, last row and last point is reached. You can select either the columns, rows orpoints to increment first.

How is a 3-D Grid Used? A three-dimensional grid structure may associate two-

dimensions of the grid (e.g., the columns and rows) with the physical coordinates on thepart whose wall thickness is to be measured. The particular measurement points on eachpart are then associated with the third dimension of the grid (e.g., the points). This scenarioallows multiple readings to be stored at each grid coordinate.

Example 6:

Start Column = AEnd Column = FStart Row = 1End Row = 4Start Point = XEnd Point = Z

Resulting file would contain the following list of ID numbers

A1XA1Y

A1ZA2X.

.

.A4Z

B1X

B1Y...F4Z

6.3.3.7 3-D Custom

A 3-D custom file is a special file type designed for 3-D file application where two of thedimensions are user defined custom lists. This allows you to define the custom Row andCustom point as a list of user defined items. The first dimension is the column referring toa starting and ending vertical column. The second dimension is the Custom Row referringto a user defined custom list of rows. The third dimension is the Custom Point referring toa user defined custom list of points. When these three dimension are defined, the result isa single ID number formed to precisely identify the exact location for each thicknessreading:

Example 7:

ColumnStart column = 01

End column = 10

Custom Row = (TOP, Middle, Bottom)Custom Point = LEFT and RightIncrement first by Custom Point and Second by Column

The resulting file would contain the following list of ID numbers:01TOP-LEFT01TOP-RIGHT02TOP-LEFT02TOP-RIGHT

Note: Copying a comment table to a file that has existing stored comments mayredefine the meaning of existing stored comments. For example, if A = HotSurfaces in the original comment table and you copy a comment table whereA = Painted Surfaces, it changes the definition of A, and thus changes themeaning of any previous stored A comments.

6.10 Saving Data

Store displayed thickness value or both the thickness and waveform in the datalogger

using the [SAVE] key. All of the appropriate calibration and setup parameters are alsostored simultaneously. (See Understanding the Datalogger on page 101 for a completedescription of what is stored in the datalogger.)

If a measurement is already stored at the current ID number, pressing [SAVE] overwritesthe old thickness reading with the current thickness reading unless the overwriteprotection feature is enabled. (See Operating the ID Overwrite Protection on page 75.)

If you do not want to save a measurement at a specific ID, press [SAVE] while nomeasurement is taken. The gage will store an LOS condition and —-.—- at the specific IDnumber.

6.10.1 Saving Thickness Readings

To save a thickness reading, do the following:

While the thickness value is being displayed, press [SAVE].

An audible beep indicates that the reading is saved. The displayed thickness value andsetup information is stored at the current ID number in the current file. If the thicknessdisplay is blank when [SAVE] is pressed, then “——-” is saved in place of a value.




910-232B 139

The ID number is automatically updated to the next ID number in the sequence. The newID number is indicated on the display. If the ID number cannot be updated a long beepsounds and the gage displays a message explaining why the ID was unable to update. Inthis case, the ID number on the display remains unchanged.

6.10.2 Saving Thickness and Waveform

To save a thickness and waveform, do the following:

While the thickness value is displayed, press [2nd F], [SAVE].

An audible beep indicates that the reading is saved. The displayed thickness value,waveform and setup information are stored at the current ID number in the current file. Ifthe thickness display is blank when you press [SAVE], then “——-” is saved in place of avalue.

The ID number is automatically updated to the next ID number in the sequence. The newID number is indicated on the display. If the ID number cannot be updated a long beep

sounds and the gage displays a message explaining why the ID was unable to update. Inthis case, the ID number on the display remains unchanged.

6.10.3 Saving Comments

Up to four comments may be stored at each identifier within a file.

To save a comment, follow these steps:

1. Press [2nd F], [ID#] (Note). The Notes table opens, similar to the display shownbelow.

Figure 100 Selecting a Comment from the Notes Table

2. Press [ ] and [ ] to highlight the desired comment to be stored. Press [ENTER]. Theselected comment is marked with a square in the box to the left of the comment lettercode.

Repeat this step up to four comments.



140 Model 25HP PLUS

3. Press [MEAS]. The next time [SAVE] is pressed these comment codes will be savedwith the thickness at the current ID number.

(See Creating or Editing Comment Tables from the Model 25HP PLUS on page 135for more information.)

Note: The comment codes are automatically untagged every time you press[SAVE]. Therefore, you must select the desired comment code before usingit.

6.11 Using the Review ID Mode

The review ID mode has three purposes:

• Review datalogger contents by scanning through stored ID locations in the active file.

• Move within the database and change the current ID location to any location thatalready exists in the database.

• Change the current ID location to any location that already exists in the database forthe purposes of editing that ID location.

To review stored thickness values and waveforms or move to an existing id location,follow these steps:

1. From the Measure mode, press [ID#]. The following data is displayed on the screen:

• Current ID Location

• Current File Name

• Stored Thickness Value• Stored Waveform (if any) with Status Flags (described in figure below)

• Stored Comments or Notes

Datalogger Flags: The area composed of four small boxes in the upper right corner ofthe waveform area is reserved for status flags describing the displayed storedthickness values. The flags are the same single letter abbreviations for status wordsthat are transmitted by the gage using the Sending commands. (See ManagingCommunications / Data Transfer on page 149.) The flags that are defined for each boxare described in the figure below.

The Review mode is indicated by ID Review section in the center of the display. Anexample is shown in the figure below:

4. Press [2nd F], [ ] to jump to the last ID Location in the file. Press [2nd F], [ ] to jump the first ID Location in the file.

5. Press [ID#] at any time to edit the displayed ID Location. (See Using the Edit ID Mode

on page 141.)6. Press [MEAS] to return to the Measure mode with the current ID Location changed

to the ID Location selected in the ID Review mode.

7. Press [2nd F], [MEAS] to return to the Measure mode with the current ID numberunchanged. The current ID Location will be the last active ID Location in theMeasure mode.

6.12 Using the Edit ID Mode

The ID Edit mode is generally used for one of two purposes:

• To change the current ID Location to a different ID Location already in the database.This mode is useful when using a large database and it would take too long to locatethe desired ID using the [ ] and [ ] keys.

• To change the current ID Location to a new ID, which does not yet exist in thedatabase. This mode is useful when a user wishes to include additional measurementpoints to the active file. Additional ID Locations can be added anywhere in thedatabase (beginning, middle, end.)

7.2 Receiving (Downloading) Files from a Computer

The same type of datalogger information, which you can send to a computer, can also bereceived or downloaded from a computer into the gage. This has two benefits:

• Retrieve thickness survey data, previously saved with ID numbers and stored in acomputer file, to the gage months or years later at the next survey date. Use thisretrieved data for three purposes:

– Guides you through the measurement sequence using the ID numbers.

– Compare current values, at the measurement site, with previous thickness values.

– Use the previous survey setup data to manually or automatically verify that thecurrent measurement setup identical.

• Create ID number sequences in a computer and then download to the gage. Thisexternally created sequence can guide you through the prescribed measurementlocation path. The ID sequence created in the computer must have setup information.The setup can be the gage default setup or any other desired sequence of setups.

The data downloaded to the Model 25HP PLUS gage must be in the same preciseformat in which data is transmitted. Panametrics-NDTTM recommends using theoptional WIN25DL PLUS Interface Program to handle all functions of interfacing,storing, and creating Model 25HP PLUS data. Other database and editor software maywork, but depends on the software design functionality. Please contact Panametrics-NDT for information on additional software data management programs.



154 Model 25HP PLUS

To Download a Data file to the Gage

7.3 Uploading/Downloading a Stored Transducer Setupto a Computer

The Model 25HP PLUS can store up to 35 custom user defined Transducers Setups. Sendthese Transducer Setups to the optional WIN25DL PLUS interface program, allowingyou to save a copy of all Transducer setups on the computer. You can also send theseTransducer Setups back to the Model 25HP PLUS. This feature is very useful to setupmultiple Model 25HP PLUS gages with the same Custom transducer setup.

7.4 Setting up Serial Communications

The Model 25HP PLUS can transmit stored data and displayed readings over its I/O(Input/Output) RS-232 cable to any device with an RS-232 serial interface connector. TheModel 25HP PLUS can also receive and execute commands sent from any device with aserial interface. Such devices include personal computers and printers. See Appendix E -Remote Control Via RS-232 on page 213 for a detailed list of Remote Control Commands.

In order to enable the Model 25HP PLUS to communicate with another device, you mustuse the correct cable and the same communication parameters must be set into the gageand the other device. These topics are discussed in the next two sections.

7.4.1 Defining RS-232 Cables

The Model 25HP PLUS must be connected to the computer with the proper cable. Sinceall computers do not have the same serial port connector, the correct cable must be orderedfrom Panametrics-NDTTM. One RS-232 cable is included with every Model 25HP PLUS,which you can specify at the time of order.

Panametrics-NDT offers the following cables that are compatible with most computer andprinter serial connectors:




910-232B 155

Note: Even matching cables and connectors do not guarantee compatibility. Toverify that a particular device serial port connector is compatible with Model25HP PLUS cable, compare the wiring information in Appendix C with theserial port wiring information given in the operators manual for the remotedevice. If there is a wiring compatibility problem, sometimes software orhardware switches may be set to change the connections. Otherwise,Panametrics-NDTTM may be able to supply a special cable for theapplication.

7.4.2 Setting up Communication Parameters

Maintaining and Troubleshooting the Model 25HP PLUS

910-232B 163

8 Maintaining and Troubleshooting theModel 25HP PLUS

This section describes how to maintain your Model 25HP PLUS by applying routing careand maintenance. Also, this section describes many troubleshooting ideas for commonproblems you may encounter.


• Providing Routine Gage Maintenance

• Maintaining Transducers

• Understanding Error Messages

• Resolving Battery and Charger Problems

• Resolving Measurement Problems

• Performing Diagnostic Self Tests

• Getting Help

8.1 Providing Routine Gage Maintenance

The Model 25HP PLUS case is sealed to prevent intrusion of environmental liquids anddust. However, it is not completely waterproof. Therefore, the unit should never beimmersed in any fluid. Use the rubber plug that comes with the unit to protect the I/Oconnector and charger connector from contamination, particularly in areas where airbornedust and aerosols are present. Use the protective pouch to provide shock and scratch

protection.The Model 25HP PLUS case is designed to withstand normal field use. However, it is anelectronic instrument, and damage is possible if not handled with some care. Observe thefollowing instructions in particular:

• Never press a key with a hard or sharp object

• When connecting cables to the gage, first align the connector with the matingreceptacle on the gage (the transducer connector pin is down, the RS-232 I/O cablekey tab facing up and the charger half-moon facing down), then carefully insert theconnector straight into the receptacle

• When removing cables from the gage, first grasp the connector (not the cable), thengently pull out from the gage

• Do not throw or intentionally drop the gage.

• Do not use strong solvents or abrasives (clean the protective pouch, case keypad, anddisplay windows with a damp cloth and mild detergent, if necessary)



164 Model 25HP PLUS

8.2 Maintaining Transducers

The ultrasonic transducers or probes used with the Model 25HP PLUS are rugged devicesthat need little care. They are not indestructible, however, and some attention to the

following items result in the longest life span.

• Make high temperature measurements only with designated high temperaturetransducers. Surfaces hotter than approximately 125ºF/50ºC damage or destroystandard tranducers if contact is made.

• Cutting, pinching, or pulling the cables causes damage to the cables. Be careful toprevent mechanical abuse to the cables. Never leave a transducer where a heavy objectcan be placed on the cable. Never remove a transducer from the gage by pulling on thecable; pull on the molded connector only. Never tie a knot in the transducer cable. Donot twist or pull the cable at the point where it connects to the transducer.

• Excessive wear at the tip of the Transducer degrades its performance. To minimizewear, do not scrape or drag the transducer across rough surfaces. Operating the

transducer may become erratic or impossible when a transducer tip becomes rough orcracked. Although some wear is normal, severe wear limits transducer life. Takeparticular care with delay line transducers, which have plastic delay lines; replacedelay lines when worn.

8.3 Understanding Error Messages

When operating the gage, certain error messages may appear. Usually these messagesindicate a problem with the operating procedure, but some may indicate a physicalproblem with the gage itself. If you do not understand an error message, call Panametrics-NDTTM for assistance.

8.4 Resolving Battery and Charger Problems

The battery life percent indicator in the lower right corner of the display shows thepercentage of operating time remaining. When the battery charge reaches about 2%, thegage automatically powers off. If the gage powers off immediately after powering on, orif it does not power on at all, then the battery is probably completely discharged.

If after recharging the battery (See Replacing the Battery Pack on page 30), the gage runsonly when the charger is connected, then you may need to replace the battery. Note, thebattery should last through several hundred discharge-recharge cycles before failing.

Remember that the battery charge indicator shows remaining operating time only whenthe charger is not connected. Do not use the charge indicator to determine when a chargingbattery has reached full charge. A battery must be charged 2 hours to completely restorefull capacity.

If the unit does not switch on even after the charger is connected for several minutes, theneither the gage itself or the charger requires service.

See page 29 to page 31 for more information.

Application Setups are a set of stored configurations of the gage parameters for

various measurement applications. Setups are optimized for such applicationfeatures as material, thickness range, and required accuracy or resolution.When the gage is turned on, the last Setup used is automatically selected and

the gage is ready to make similar measurements.If the application has changed, choose an Application Setup name based on thenew application (refer to Table 12 on page 178).

Alarm The gage may be set to indicate visually andaudibly whenever the measured thickness isless than a user-set Low Alarm value orgreater than a user-set High Alarm

value.The default is Low Alarm value =0.000, High Alarm value = full scale, andAlarm Measure mode OFF.

Electrical Definition and Data Format

Data is transmitted on one line (data out of gage) and received on another line (data intogage). Transfer is asynchronous serial. Baud rate, word length, stop bits and parity areselectable from the keyboard. Data consists of ASCII coded character strings.

Signal levels are RS-232 C/D compatible. Mark is less than -2.5 volts. Space is greaterthan +2.5V. The maximum output signal range is ±5.50 volts. The maximum input signalrange is ± 20 volts.

The following two hardware handshake lines are included:

DTR: The gage sets DTR low (<-2.5V) when it is not able to receive data. DTR is high(>+2.5V) at all times.

DSR: A high (>+2.5V) supplied by the external device (or by being connected to theDTR line) enables the gage to transmit data. A low (<-2.5V) supplied by theexternal device, or by being connected to the RTS line, prevents the gage fromtransmitting data.

Note: If the external device does not provide the proper DSR signal, then you mustconnect DTR to DSR (jump pin 6 to pin 20 in the 25 position cableconnector), or in the 25 pin connector on the attached equipment.

Thickness Table: A thickness table consists of a header line, thickness data andwaveform data. The thickness table has some differences in the different formats. Thereare six flags associated with each thickness reading in the Thickness Table. In formats

F-1 and F-2, the sixth flag is DN Flag; while in format F-5, the sixth flag represents a

comment code. These are positional and their possible values are shown below:

A single line consisting of the text “OK” immediately follows the end of the ThicknessTable.

Setup Table: This table consists of a header line followed by 1 to 32 data lines. There isone data line for each unique setup listed in the thickness table. In general, manythicknesses/waveforms may share a common setup. The number of setups is limited to

64. When the setup table is full, any new setups are allocated the #00 and this entry in

the setup table indicates such status. Setup table has some differences in the differentformats.

A blank line precedes the Setup Table.



Appendix E - Remote Control Via RS-232

910-232B 213


You can control the Model 25HP PLUS from an external computer or programmablecontroller using the serial RS-232 cable. In addition, you can also perform most gage

keypad functions by transmitting the proper commands to the gage over the serial cable.These functions include setup, calibration, and data storage and retrieval. Each Model25HP PLUS key has a corresponding remote command. For example, you can load acomplete setup and calibration parameters to the gage from a computer at the beginning ofeach workshift without performing a manual setup and calibration.

Another computer control feature is the on-line or robotic thickness measurement andreporting. A computer or machine controller directs the positioning of an ultrasonictransducer on a robot arm while at the same time electronically entering the keys on theModel 25HP PLUS. For example, an unattended computer could set up and change toDifferential Measurement mode, change resolution, calibrate and/or set differentvelocity values, or read the various thickness values. The controlling program can repeatthe same sequence of steps for each product to be measured.

The command set is divided in two formats:

Multi-Character commands: Multi-Character commands consist of two or morecharacters and maybe followed by a terminator.

Single-Character commands: Single-Character commands consist of a single characterwith no terminator, used to imitate keystrokes on the gage remotely.

To change the command formats, follow these steps.

1. Press [2ndF], [0] (SP MODE).

2. Press [ ] and [ ] to highlight the Communication option. Press [ENTER].

3. Press [ ] and [ ] to highlight the Comm Protocol option.

4. Press [ ] and [ ] to toggle between the SINGLE or MULTI character command.Press [ENTER].

Multi-character Commands

This section describes all Multi-Character commands and illustrates the syntax used witheach command.

Note: Commands are case sensitive and, if appropriate, terminated with a carriage-return line-feed pair i.e., ( /r/n ) .
