Additional Description • Film strips are automatically measured using a motorized control mechanism.

Data is sorted and available for viewing or transmitting.

• Operation is performed using 4 keys and has an interactive 16 character/2-line Liquid Crystal Display. The 391 instrument contains twelve channels that allow you to monitor up to twelve different processors (the 390 instrument contains four channels). The 391 also saves the measurement data of the last 32 strips measured for each channel. The measurement data for each strip includes 21 steps of density, time/date, and temperature. Temperature must be entered manually.

• (391 instrument only) Reference data can be entered manually or automatically.

• Stores each measured density value as an absolute density value. These density values can be viewed as absolute density values or as values deviated from their reference values.

• Comes preset with common process control equations used for interpreting data. Basic equations types are: Density at step number, Exposure level at density, Density at exposure level, Density Difference (Contrast), Gradient, and Mid Density (Speed).

• Contains an editor function that permits you to set the Aim Values, Control Limits, Channel Names, and Equation formats that best suit your individual requirements. The Editor function also permits copying the setup of one channel to another channel. This is most useful when multiple processors of the same type are in use. The editor function can also be used to delete an individual unit or an entire database from a channel. Setting the Aim values and Control limits informs the densitometer when to display Go/No Go indications. After each measurement the unit displays if the limits were exceeded.

• Provides Trend detection and warning.

• (391 instrument only) Contains Automatic Step Selection – identifies Mid Density, High density and Low Density according to the American College of Radiology Mammography Quality Control Manual definition.

• (391 instrument only) Provides networking capabilities when used in conjunction with commercially available networking processor QA programs, (ex. X-read Net). The densitometer uses an external modem to transmit measured data.

Film Strip and Guide Information All control strip types should have at least a 30.5mm (1.2”) leader before the outside edge of the first step. Refer to your Sensitometer Operation Manual for the proper method for exposing film.

The instrument has an adjustable film guide that helps to guide the film through the instrument. This guide can be positioned from .5” to 3” to the right of the center triangle. Move the film guide by sliding it left to right.

Specific Film Guide Placement Place the film guide completely to the left for film that was exposed with the X-Rite 334 Sensitometer. Place the film guide on the second dot for film that was exposed using the X-Rite 383, 384, 393 or 394 Sensitometer. Align the guide as required for the Phantom, Darkroom Fog and Screen Contact test films.

Additional Strip Notes • If a strip becomes “jammed” in your instrument during a measurement, slowly

pull strip out from the front of the instrument.

• When measuring single emulsion films, insert the strip with the emulsion side down.

• Before measuring, inspect the film for any pin spots or flaws on the 21 steps. If there is a flaw or spot on a step, it could cause an inaccurate measurement.

• The exposed film must have a sensitometric exposure with a gamma of 0.7 or greater on steps 7 through 15. There must be a visible density difference between each step (density must increase by at least 0.11D between those steps).

• To ensure accurate measurement results, step 1 of the film must be inserted into the densitometer first (low density end).

• A strip is inserted into the instrument until it rests against the drive rollers.

• After a strip is initially inserted into the instrument, a one second delay occurs before the drive mechanism is activated to allow time for proper alignment.

• The instrument cannot reliably measure strips that are creased.

Cine Type Film Strip Insert the film strip (emulsion side down) into the 35mm slot located under the film guide until it rests against the drive rollers and release when the motor takes hold.

Sheet Type Film Strip Position the side of the strip with the exposed steps tightly up to the stop. Insert the film emulsion-side down (for single emulsion film) until it rests against the drive rollers and the motor is activated. Do not release; with slight pressure continually hold the film against the stop, guiding it to prevent any skewing, while the film is being measured.

Process Control

Film Response to Exposure The 390/391 densitometer is designed to measure film that has been exposed by an X-Rite sensitometer. The sensitometer uses a 21-step light modulator and a known quantity of light to expose the film. The maximum amount of light is emitted from Step No. 21. Each successive step emits approximately 70.7% of the light emitted from the step adjacent to it (.15 log exposure). The film responds to this exposure in a predictable manner called the D-Log E Curve, (Density-Log Exposure Curve). The following figure shows the response of a typical radiographic film exposed by a sensitometer. The portion of the curve that changes most with variations in processing is called the "straight line portion" of the curve.

It is not necessary to plot D-Log E Curves to monitor automatic processors in normal laboratory environments. A simpler method is to record the three values (base+fog, mid density, & density difference) on the D-Log E Curve which contain most of the data.

NOTE: If exposure step editing is required on the densitometer, refer to the Equation Editor procedure in the Editing section.

DENSITY DIFFERENCE(CONTRAST INDEX)

BASE+ FOG

MID DENSITY(SPEED INDEX)

Base+Fog: The portion of the film that has the least exposure is called the Base+fog. It is the base support density plus any silver emulsion density developed in the area where negligible exposure should occur. The densitometer was preset at the factory to measure the Base+Fog at step 1.

Mid Density (Speed Index): The density step on the exposed film that has a density closest to but not less than 1.20D. This step is a direct indicator of film speed. Variations in processor conditions are monitored on this step. The 390 densitometer is preset at the factory to measure the Speed Index at step 11. The 391 densitometer automatically chooses this step.

Density Difference (Contrast Index): This is a calculation of the slope in the straight-line portion of the D-Log E Curve. Choose the High Density (HD) step as the step closest to 2.20D. The Low Density (LD) step is chosen as the step closest to but not lower than 0.45D. The Contrast Index or Density Difference is the difference between HD and LD. The 391 makes these selections and the calculation automatically. For the model 390, this must be performed manually.


1-9

Monitoring a Processor The densitometer can monitor a processor on each of its channels. The channel names which appear on the print-outs are preset to "Xray Lab A", "Xray Lab B" and so on. These ten character names may be changed if desired (refer to the Channel Name Editor procedure in the Editing section).

Reference Entry Aim values for Base+Fog, Mid Density (Speed Index), and Density Difference (Contrast Index) must be established for each processor being monitored. This is done automatically by measuring several (3-5) reference strips that are exposed and processed when the processor is operating in an optimum fashion. Refer to Section Six, Reference Operation for the procedure on measuring the reference strips.

Trending The instrument incorporates trend detection per ACR Mammography QC Manual section III.2B. Trending detects three or more data points moving in one direction (either upward or downward) in the MD, DD, or B+F.

Running Daily Strips Control Strips should be processed and measured daily. The densitometer automatically measures the 21 densities, calculates the process control parameters, and indicates whether or not the measured strip is within control limits. Refer to the Section 5, Strip Operation for the procedure on measuring strips.

Viewing or Plotting History (391 Densitometer only) The History function permits you to view all the data related to each strip in the database, or print the process control record. When the process control record is printed, processor and film information must be manually recorded at the top of the form (see an example of a printer plot in History Usage). A box of film should be set aside from regular stock for exclusive process monitoring. New film stock will require measuring new reference strips using the cross-over procedure. This is necessary because small density changes are possible between film batches.

One new set of references may be entered for each data set (32 measurements). The date the new references are entered will be indicated on each field of the process control record as a vertical dotted line. The corresponding new aim value will also be printed below each field.

NOTE: The densitometer can store only two references (aims) per channel. If the history plot shows more than one vertical dotted line, it is recommended that you delete all old data that precedes the next to the last vertical dotted line or all data preceding the last dotted line. This will help to eliminate errors in interpreting the data.

S E C T I O N O N E

Troubleshooting Film You should always keep the last channel of your instrument open so that it can be used as a "scratch pad" when troubleshooting a processor. This allows you to run film strips and correct the processor problem without interfering with the monitoring channels.

The following procedure is recommended for troubleshooting out-of-tolerance processors.

1. Copy the channel being monitored to the last channel.

2. Measure films on the last channel and adjust processor as required.

3. When the processor is back in control measure a film on the original channel to verify correction.

2. Instrument Calibration Section Two Contents • Calibration Information

• Calibration Verification Procedure

Calibration Information The instrument features automatic calibration and does not require any manual adjustments. The 381-25 Calibration Verification Reference provides a method to periodically verify and document the performance of your instrument.

To maintain accuracy verification, keep the strip in supplied envelope when not in use and store it in a dry, cool environment. Periodically, measure the strip to verify accuracy. Only dust or clean the surface with a soft camel hair brush.

Reference strips tend to drift in density with time; consult the manufacturer's specifications for expected density changes. If your reference strip gets ruined or worn, you can order a replacement from X-Rite or your authorized dealer. Order Part Number 381-25.

This film is intended to verify film for scanning densitometers and should not be used as a replacement for the transmission reference supplied with other densitometers.

Frequency of Calibration Verification Under normal operating conditions, the instrument’s calibration should be verified once a week or when the instrument displays a message regarding calibration.

Calibration Verification Procedure NOTE: Make sure the verification strip is free of dust, dirt, and smudge marks. Refer to the General Maintenance section for cleaning procedure. Handle cal strip by the edges.

1. In page 1 of the main menu, press the [p1] key to enter page 2 of the main menu.

2. In page 1 of the setup menu, repeatedly press the [p1] key to enter page 3 of the setup menu.

3. Press the [cal] key to enter the CAL STRIP screen.

4. Press the [read] key to initiate procedure.

S E C T I O N T W O

2-2

CAL STRIPread view print

5. Insert the verification reference into the scanning densitometer in the direction indicated by the arrow at the top of the film.

6. The two middle keys (view) are used to page through the measured calibration values. Compared the density values listed on the verification reference to verify the calibration of the instrument. The measured values should be within +/- 0.03D or 2% (whichever is greater) compared to the values on the reference label. If the values are not within this tolerance, ensure that the film is not dirty or damaged and re-measure the film. If the values are still beyond this tolerance, clean the optics (refer to the General Maintenance section).

7. A record of the verification measurement can be sent to a printer by pressing the [print] key. The printout should be dated and the reference density values recorded at the required steps.

MQSA (Mammography Quality Standards Act) Used to set the Auto Step Select option, ReCertification Warning message, and field terminology used.

AUTO STEP SELECT – automatically determines the steps at which mid density (speed index) and density difference (contrast index) are read during a reference measurement. The instruments default steps are, step 11 for mid density, and steps 9 and 13 for density difference. Requirements are that the MD use the first step with a density >1.20D. The LD step must be the first step with density >0.45D, and the HD step must be the step with density closest to 2.20D. RE-CERT WARNING – when set to yes, the instrument displays a warning message at power-up when re-certification is required. The re-certification period last for approximately one year. Instruments in the United States should be returned to X-Rite for re-certification when this message appears. S.Indx & C. Indx – determines the terminology that is used for the exposure fields. When set to MD/DD, Mid Density and Density Difference are used. When set to DEFAULT, Speed Index and Contrast Index are used.

ref (reference) – 391 Instrument Only Used to turn the reference function off or on. If the reference is on, the instrument displays if limits were exceeded after each measurement. Also, when view or history you are prompted to select either meas (measured) or dev (as deviated from reference). If reference is off, limit violation is not displayed and you are not asked to select meas or dev.

High Density Film Setup The 390 and 391 are able to consistently and reliably measure films with a D-Max of 4.50D optical density. Note however, that recent developments in film technology have resulted in photographic media that may exceed 5.00D. All measured steps up to 4.50D are accurate and reliable, but steps above 4.50D can cause instrument errors if the high density feature is not activated. The feature allows all steps reading above 4.50D to be reported as “4.50D”, and the rest of the steps to be accurately and reliably reported. Follow these instructions to select the “High-Density” setting.

Reference Crossover Procedure The new function is used to enter new reference data into the selected channel. To provide a better overall average, it is recommended that five reference strips be measured. However, less than five can also be averaged when the exit key is pressed during the measurement sequence.

The crossover function is used whenever a new box of film is used for processor quality control. A “cross-over” between the old film reference values and the new film reference values must be performed. Performing a cross-over prevents the reference values from being affected by the emulsion differences between the two film batches. The cross-over procedure is performed using the last five films from the old box, and five films from the new box. The cross-over calculations are performed automatically.

1. Select the channel where the cross-over is to be entered (refer to Section 1 for channel selection).

7. QC Operation Care must be taken when handing strips. Fingerprints on measurable patches can affect density values.

In addition to measuring 21 step processor QC films, the 390/391 Densitometer can measure films produced for other QC tests. Phantom Images, Darkroom Fog and Screen-Film Contact test films, can be measured using the 390/391 Densitometer. Spot Readings and Scan Reading are also available as QC functions.

IMPORTANT! When inserting strips into the instrument, there should be at least a 30.5mm (1.2”) leader before the outside edge of the first measurable target or the first target may not be detected.

Phantom Images The 390/391 instrument supports six phantoms for measurement. Consistent placement of disks, test points and step wedges on the film insert is critical to ensure accurate readings by the instrument’s pattern recognition routines.

Due to the variation in phantoms supported, each phantom is illustrated to ensure accurate alignment with the measurement path.

The best way to measure a phantom is to locate the instrument on a white or lighted background. This allows better visibility when aligning the phantom to the instrument measurement path.

Darkroom Fog The density difference measurement for the darkroom fog test specified in the ACR Mammography Quality Control Manual can be performed using this function.

A Mammography Phantom Film Mask, P/N SD01-64 (MPFM) is provided with the 390/391 densitometer. Use the mask to produce the fog boundary in the correct location on the exposed film. Location of the phantom image on the exposed film is critical. When processed the phantom image must appear on the exposed film so the numeric label is divided in half. Place the film in the MPFM as shown to expose the fog boundary in the correct location. Correct location of the fog boundary will insure its recognition by the instrument’s pattern recognition routines.

Spot Reading The spot reading function provides a method when an occasional density measurement is required outside a standard exposure pattern. For best results, the spot to be measured should be a uniform density across a minimum area of 0.25" (6.35mm). Because a spot measurement is a “blind” measurement, a template is required to properly locate the area being measured in the optical path of the instrument. A template is provided at the end of this procedure. The spot must fill the template’s measurement opening to achieve an accurate reading.

Some slight pressure may be required when positioning the spot under the lamp if the strip extends 1.3" (33.02mm) past the lamp (due to drive roller mechanism).

NOTE: The lamp is located approximately 2.1" (53.34mm) from left edge of the slot opening and 2.0" (50.8mm) from the front edge of the slot opening.

The QCMed Network provides the link between X-Rite 391 densitometers and QC computers—providing a new dimension to Quality Control for medical labs. QCMed is an advanced protocol that is used between the 391 and a central Quality Control monitoring host computer.

With a modem, the 391 will communicate with a remote quality control computer system where comprehensive tracking and diagnostic evaluation occurs. If desired, the QCMed protocol can allow remedial instructions or data to be transmitted back to the densitometer where it's printed out in text form on the display or available printer.

QCMed data is transferred in block format with error detection techniques and valid transfer acknowledgment. QCMed data transfer can be initiated manually or automatically.

The 391 has several internal modem setup features such as: automatic dialing of QC computer's phone number; Lab ID number program; etc.

QCMed compatible host software (running on a PC) is available from the following

Prefix Number The prefix number is used to set the parameters of the modem. The default prefix is “S0=0&F0&K0”, which works with US-Robotics 14.4 Sportster modems (not Sportster Si modem).

The following commands are the standard commands most users will require. Additional commands not listed are available for specific requirements. Consult your modem’s user manual for a description of these special commands.

If a modern over 2400 baud it to be used, refer to Modem Consideration after Prefix Command Descriptions.

Command Description B (Bell) B1 = Bell 103 & 212A (USA) and B0 = CCITT (European)

L (Modem Speaker Volume) L1 = Low speaker volume, L2 = Medium speaker volume, and L3 = High speaker volume.

M (Monitoring Speaker) M0 = Speaker off all the time. M1 = Listen to speaker for dial tone, busy, etc., and turns off as soon as the carrier signal is recognized. M2 = Speaker on for complete call.

S (Register Value) The “S” command is used to change the value of a register. The “=” command puts new values into the selected register. Ex. S6=3 (causes a 3 sec. dial tone wait). REG RANGE UNITS DEFAULT DESCRIPTION S0 0..255 rings 0 rings to answer S6 0..127 sec. 2 dial tone wait S7 1..255 sec. 30 carrier wait S8 0..255 sec. 2 comma pause S9 1..255 .1sec. 6 carrier delay S10 1..255 .1sec. 7 hang-up delay S11 50..255 .001s. 70 touch tone duration S12 20..255 .02s. 50 esc code time

W (Wait) Causes the modem to waits up to 5 seconds between commands.

X (Selects Result Code Set)

NOTE: When a call is initiated, the instrument sets the modem to “X1” or “X3”. It is a good idea to avoid using “X0” in the prefix because the instrument expects extended result codes. Failure to receive extended result codes will cause the session to fail.

X0 = the basic result code set. The modem blind dials, waiting S6 seconds before dialing a number. The result code for both 300bps and 1200bps connection is 'CONNECT.' X1 = the extended result code set. The modem blind dials, waiting S6 second before dialing a number. The result code for a 300bps connection is 'CONNECT', while 1200bps result code is 'CONNECT 1200.' X2 = a extended result code set just like X1, except that the modem looks for a dial tone before dialing. X3 = the extended result code set just like X1, except that the modem looks for a busy signal after dialing. X4 = both X2 and X3 functions.

Considerations When Using High Speed Modems (modems over 2400 baud). A prefix of “S0=0” is fine for 2400 baud modems and slower. However, additional modem commands may be required if you are having difficulty “connecting” with a faster modem.

These commands are necessary because the cabling of the instrument does not support “hardware handshaking” which is found in newer error-correcting / data compressing modems.

You must determine the correct modem string to perform the operations from your modem manufacturer's manual. Listed below are four examples of modem commands:

US-Robotics Hayes Rockwell Microcom/ 14400 Sportster Compatible Compatible Motorola

1) disable MNP data compression &K0 S46=0 %C0 %C0 2) enable variable serial port rate &B0 &Q0 &Q0 \J1 3) disable modem flow control &H0&R1 &K0 &K0 \G0 4) disable serial port flow control &I0 &K0 &K0 \Q0

NOTES: Items 2, 3, and 4 are included in the US Robotics “&F0” factory preset. Use S0=0 in the prefix, the “rings” till answer menu option will override this anyway. The 391 default modem prefix is S0=0&F0&K0, which should work fine for a USRobotics Sportster 14.4K modem (recommended modem). Use of “USRobotics Si” modem is not recommended.

Setting Prefix Number

NOTE: Since the screen only displays “16” characters at a time, the characters will scroll to the left when the cursor is moved beyond the 16th character. Any characters that have scrolled off the screen will reappear when the cursor is returned to position one.

1. At the SELECT EDITOR screen, press the [pfx] key to access prefix editor screen.


3. After prefix is set, press the [save] key to store prefix and return to the Network Menu screen.

NOTE: Use the “¥” character in place of the “\” if your modem requires a “backslash” character.

Setting Lab Identification Number The Lab ID number is used to identify your particular lab when transferring data. The Lab ID can be up to 8 characters long and consist of both letter and numbers.

1. At the SELECT EDITOR screen, press the [id#] key to access lab ID screen.


3. After lab ID is set, press the [save] key to store lab ID and return to the Network Menu screen.

Setting Answer on Ring Number The “answer on ring” screen is used to enter the ring number that the instrument will connect on. The number of rings can be set from “0” to “9.” The default setting for ring number is “0.” A zero setting tells the instrument not to answer the incoming call.

Do not attempt to change the “rings till answer” by editing the default “s0=0&F0&K0” modem prefix.

NOTE: When using a “Y” cable, part number SE108-07 must be used. This cable routes the “ring indicator” line from the modem (connector “B”) to pin 5 of the instrument. The single cable (SE108-08) already includes this line.

1. At the SELECT EDITOR screen, press the [ring] key to access Answer on Ring editor screen.

2. Use the [↑] key and [↓] key to page through the available numbers.

3. After number is set, press the [exit] key to store number and return to the Phone Options screen.

Auto Answer MODE In order for the Auto Answer mode to work properly your modem must be set up properly. Many modems have a set of configuration switches (also called DIP switches) located on the rear or behind the front panel of the modem. These switches must be set so that the modem:

(1) is using smart modem (enables Hayes compatible commands)

(2) sends result codes (some modems allow you to disable result codes)

(3) auto answer is disabled (turned off).

Many modems will have some or all of the above switches.

Any additional switches may be in either position, however, check your modem manual for a description of each switch and try to determine which switch settings will work best for your application.

The instrument monitors the ring indicator (RI) line (pin 22) coming from your modem (when using an X-Rite cable that routes the ring indicator line from the modem, see Appendix for specific part numbers). Each time your phone rings, the RI line will go active. The instrument will then send the “ATA” command to the modem to cause it to answer the phone.

If the message “Check Modem Hardware” is displayed when performing the above steps, check your cables between the instrument and the modem and also check the configuration of the modem.

Special Note for 391 users with Printers and Modems When using a printer and a modem, you need a “Y” cable that does not have the Ring Indicator (RI) line going to the modem. The printer requires this line during graphics printing. This configuration will not allow the 391 to answer incoming phone calls without the RI line going to the modem.

• Choose a “Y” cable with RI (part number SE108-07-01 or 881-122) if you want your modem to answer incoming calls, and don’t care about printing graphs to the printer.

• Choose a “Y” cable without RI (part number SE108-09-01 or 881-121) if you want to print graphs with your printer and don’t want your modem to answer incoming calls.

Receiving Notes on the Display With the QC computer link established, a two line note of up to 32 character can be received and displayed.

NOTE: Receiving notes on the display only occurs during a network session if the host software “decides” (or determines it necessary) to send a note.

1. At Main Menu level, repeatedly press the [p#] key until “p3” is displayed, then press the [netw] key.

2. Press the [note] key.

• A 32 character message will display if information is available.

3. Press any key to return to network menu.

Receiving Notes on the Printer When using both a modem and a printer with the 391 (via a “Y” interface cable), the host computer can send notes/corrective actions directly to a printer during a network session. This feature is implemented by the remote host software running on the host computer.

You must have a “Y” interface cable P/N SE108-09-01 or P/N 881-121 (provided with your instrument) to receive notes on your printer. This “Y” interface cable does not allow the 391 to answer calls to the modem. Therefore, the “rings” parameter must be set to “0” in the network configuration menu.

NOTE: Receiving notes on the printer only occurs during a network session if the host software “decides” (or determines it necessary) to send a note.

Cleaning the Instrument Your instrument requires very little maintenance to achieve years of reliable operation. However, to protect your investment and maintain reading accuracy, a few simple cleaning procedures should be performed from time to time.

General Cleaning Whenever required, the exterior of the instrument may be wiped clean with a cloth dampened in water or a mild cleaner.

NOTE: DO NOT use any ketone solvents to clean the unit, this will cause damage to the cover.

Cleaning the Optics The optics and drive wheel assembly should be cleaned once a week in normal environments, and more often in dirty or dusty environments.

1. Carefully lift instrument and insert tube from canned air into film strip insertion slot.

2. With back and forth motion, spray clean, dry air from one side to the other—do this several times. This should remove any accumulated dust and lint from the optics and wheel assembly.

WARNING: DO NOT invert cans that use freon as a propellant, doing so could cause damage to the optics assembly.

Troubleshooting Tips

Important! Before proceeding with the following troubleshooting chart:

Insure strip being measured has been properly inserted and is free of smudges, scratches, and blemishes. Insure the strips and unit are free of dust and lint.

Proper anti-static control must be used when replacing the lamp and batteries.

PROBLEM CAUSE SOLUTION Measurement densities incorrect.

Read lamp weak. * Replace lamp (see Sec. 9).

Measurement densities drift.

Read lamp weak.* Replace lamp (see Sec.9).

Read lamp not working. Read lamp bad. * Replace lamp (see Sec.9). Measurement densities un-repeatable/incorrect.

Film miss-aligned. Film has blemishes or scratch.

Reinsert strip. Use different film strip.

<INVALID READING!> appears after measurement. (Refer to Appendix for more invalid reading messages)

Film did not have long enough leader, 30.5mm (1.2”).

Use film with correct leader.

Exposed region not properly aligned.

Make sure film feeds straight through unit and does not skew.

One or more measurement patches are cloudy, have excessive gradients, or have flecks.

Process and measure a new film. Note: A small clear area in a high density patch causes large errors. This could be caused by dust specs in the sensitometer during exposure. If so, clean sensitometer and process another film.

Motor drive roller slipping due to restraint or obstruction, or contamination of rollers from reading wet strips.

Remove restraint/obstruction or dry drive rollers with air.

Film did not meet required exposure criteria.

Adjust sensitometer exposure time to meet requirements (Section 4).

* The instrument has a lamp failure monitor. The monitor will usually indicate when the lamp needs replacement.
