CONNECTING THE FMA-PC1600The inlet and outlet connections to the FMA-PC1600 are located below the displays for their respective flow ranges. Inlet connections are located on the left and the outlet connections are located on the right (see page 6) The connections are either 1/8”, 1/4”, 3/8”, 1/2” or 6mm, 10mm, 12mm push-connect style tubing fittings with each fitting corresponding to a single flow range. Use appropriately sized plastic tubing to connect the flow source to the corresponding inlet fitting. If necessary, connect the corresponding outlet fitting to the original source destination with proper tubing.

CAUTION: Push-connect fittings are easy to use, as no special tools are required to make the joints. However, special attention must be paid when cutting the tube — as the O-ring inside of the fittings can easily be damaged.

It is essential to use the correct cutter such as a pipe slice for copper pipe or dedicated plastic pipe cutters for plastic tube — Do not use a saw because any burrs left on the tube can damage the O-ring and cause the joint to leak!

Cut your tube to the required length using the dedicated plastic pipe cutters, making sure you have a straight cut with no burrs. Then push the tubing carefully into the fitting on the bulkhead panel. Softer polyurethane tubing will work best, as opposed to some of the harder plastic tubings available. It decreases the chances of damaging the O-rings.

If the outlet fittings are not connected to your piping, the gas being measured will vent to atmosphere at the outlet fittings!

Use protective eyewear!

Never Vent Flammable Gases To Atmosphere!

POWERThe FMA-PC1600 is designed to operate on eitherfour AA Alkaline batteries or via a 9-30 Vdc power supply (minimum 150 mA @ 24Vdc). The batteries will operate the FMA-PC1600 for about 8 hours under normal usage.If the batteries lose significant power, the low battery light will come on and the batteries should be replaced or alternate power should be applied. When the replace battery light is on the accuracy of the meters’ readings cannot be guaranteed.

PRESSUREMaximum operating line pressure for FMA-PC1600s with FMA-1600A units is 145 psig (1 MPa).If the line pressure is higher than 145 psig (1 MPa), use a pressure regulator upstream from the flow meter to reduce the pressure to 145 psig (1 MPa) or less.Maximum operating line pressure for FMA-PC1600s with FMA-LP1600A units is 50 psig.

Exceeding the maximum specified line pressure may cause permanent damage to the solid-state differential pressure sensor.

Do Not subject an FMA-1600A Differential Pressure sensor to upstream-downstream pressure differentials exceeding 75 PSID.Do Not subject a FMA-LP1600A Differential Pressure sensor to upstream-downstream pressure differentials exceeding 15 PSID.

While high static pressure will typically not damage the dp sensor, sudden pressure “spikes” can result in complete failure of the sensor.

A common cause of this problem is instantaneous application of high-pressure gas as from a snap acting solenoid valve either upstream or downstream of the meter. If you suspect that your pressure sensor is

damaged please discontinue use of the meter and contact Omega.

MAIN This mode defaults on power up, with mass flow as the primary displayed parameter. The following parameters are displayed in the Main mode.

Gas Absolute Pressure: This sensor references hard vacuum and reads incoming pressure both above and below local atmospheric pressure. This parameter is moved to the primary display by pushing the button above PSIA. The engineering unit associated with absolute pressure is pounds per square

inch absolute (psia). This can be converted to gage pressure (psig) by subtracting local atmospheric pressure from the absolute pressure reading:

PSIG = PSIA – (Local Atmospheric Pressure)

Gas Temperature: FMA-1600A flow meters measure the incoming temperature of the gas flow. The temperature is displayed in degrees Celsius (°C). This parameter is moved to the primary display by pushing the button above °C. Pushing the button again allows you to select 0C (Celsius), K (Kelvin), 0F (Fahrenheit) or 0R (Rankine) for the temperature scale. To select a temperature scale, use the UP and DOWN buttons to position the arrow in front of the desired scale. Press SET to record your selection and return

to the MAIN display. The selected temperature scale will be displayed on the screen.

Tare: Pushing the TARE V button tares the flow meter and provides it with a reference point for zero flow. This is an important step in obtaining accurate measurements. It is best to zero the flow meter each time it is powered up. If the flow reading varies significantly from zero after an initial tare, give the unit a minute or so to warm up and re-zero it.If possible, zero the unit near the expected operating pressure by positively blocking the flow downstream of the flow meter prior to pushing the TARE button.

Zeroing the unit while there is any flow will directly affect the accuracy by providing a false zero point. If in doubt about whether a zero flow

condition exists, remove the unit from the line and positively block both ports before pressing the TARE button. If the unit reads a significant negative value

when removed from the line and blocked, it was given a false zero. It is better to zero the unit at atmospheric pressure and a confirmed no flow condition than to give it a false zero under line pressure.

Volumetric Flow Rate: This parameter is located in the lower left of the display. It is moved to the primary display by pushing the button below CCM in this example. Your display may show a different unit of measure.Mass Flow Rate: The mass flow rate is the volumetric flow rate corrected to a standard temperature and pressure (typically 14.696 psia and 25 °C). This parameter is located in the lower middle of the display. It can be moved to the primary display by pushing the button below SCCM in this example. Your display may show a different unit of measure preceded by the letter S.

To get an accurate volumetric or mass flow rate, the gas being measured must be selected. See Gas Select, page 12.

MENU: Pressing MENU switches the screen to the Select Menu display.

Flashing Error Message: An error message (MOV = mass overrange, VOV = volumetric overrange, POV = pressure overrange, TOV = temperature overrange) flashes when a measured parameter exceeds the range of the sensor. When any item flashes, neither the flashing

parameter nor the mass flow measurement is accurate. Reducing the value of the flashing parameter to within specified limits will return the unit to normal operation and accuracy.

If the unit does not return to normal operation contact Omega.

MISCELLANEOUS Miscellaneous is accessed by pressing the MISC button on the Select Menu display. Next select either MISC1 or MISC2.

MISC1 will display as shown at left.ZERO BAND refers to Display Zero Deadband. Zero deadband is a value below which the display jumps to zero. This deadband is often desired to prevent electrical noise from showing up on the display as minor flows or pressures that do not exist. Display Zero Deadband does not affect the analog or digital signal outputs.ZERO BAND can be adjusted between 0 and 6.3% of the sensor’s Full Scale (FS). Press ZERO BAND. Then use SELECT to choose the digit with the arrow and the UP and DOWN buttons to change the value. Press SET to record your value. Press CLEAR to return to zero.Pressure Averaging and Flow Averaging may be useful to make it easier to read and interpret rapidly fluctuating pressures and flows. Pressure and flow averaging can be adjusted between 1 (no averaging) and 256 (maximum averaging). These are geometric running averages where the number between 1 and 256 can be considered roughly equivalent to the response time constant in milliseconds.

This can be effective at “smoothing” high frequency process oscillations such as those caused by diaphragm pumps. Press PRESS AVG. Then use SELECT to choose the digit with the arrow and the UP and DOWN buttons to change the value. Press SET to record your value. Press CLEAR to return to zero.

Press FLOW AVG. Then use SELECT to choose the digit with the arrow and the UP and DOWN buttons to change the value. Press SET to record your value. Press CLEAR to return to zero.Setting a higher number will equal a smoother display. LCD CONTRAST: The display contrast can be adjusted between 0 and 31, with zero being the lightest and 31 being the darkest. Use the UP and DOWN buttons to adjust the contrast.

RS232 Output and InputConfiguring HyperTerminal®:

1. Open your HyperTerminal® RS232 terminal program (installed under the “Accessories” menu on all Microsoft Windows® operating systems).

2. Select “Properties” from the file menu.3. Click on the “Configure” button under the “Connect To” tab. Be sure the

program is set for: 19,200 baud (or matches the baud rate selected in the RS232 communications menu on the meter) and an 8-N-1-None (8 Data Bits, No Parity, 1 Stop Bit, and no Flow Control) protocol.

4. Under the “Settings” tab, make sure the Terminal Emulation is set to ANSI or Auto Detect.

5. Click on the “ASCII Setup” button and be sure the “Send Line Ends with Line Feeds” box is not checked and the “Echo Typed Characters Locally” box and the “Append Line Feeds to Incoming Lines” boxes are checked. Those settings not mentioned here are normally okay in the default position.

6. Save the settings, close HyperTerminal® and reopen it.

Streaming Mode

In the default Polling Mode, the screen should be blank except the blinking cursor. In order to get the data streaming to the screen, hit the “Enter” key several times to clear any extraneous information. Type “*@=@” followed by “Enter” (or using the RS232 communication select menu, select @ as identifier and exit the screen). If data still does not appear, check all the connections and COM port assignments.

Streaming Mode – Advanced

The streaming data rate is controlled by register 91. The recommended default rate of data provision is once every 50 milliseconds and this is suitable for most purposes.

If a slower or faster streaming data rate is desired, register 91 can be changed to a value from 1 millisecond to 65535 milliseconds, or slightly over once every minute.

Below approximately 40 milliseconds, data provision will be dependent upon how many parameters are selected. Fewer data parameters can be streamed more quickly than more. It is left to the user to balance streaming speed with number of parameters streamed.

To read register 91, type “*r91” followed by “Enter”.

To modify register 91, type “*w91=X”, where X is a positive integer from 1 to 65535, followed by “Enter”.

To return to the recommended factory default streaming speed, type “*w91= 50”.

Tareing via RS232:

Tare –Tareing (or zeroing) the flow meter provides it with a reference point for zero flow. This is a simple but important step in obtaining accurate measurements. It is good practice to “zero” the flow meter each time it is powered up. A unit may be Tared by following the instructions on page 10 or it may be Tared via RS232 input.

To send a Tare command via RS232, enter the following strings:

In Polling Mode: Address$$V<Enter> (e.g. B$$V<Enter>)

Changing From Streaming to Polling Mode:

When the meter is in the Streaming Mode, the screen is updated approximately 10-60 times per second (depending on the amount of data on each line) so that the user sees the data essentially in real time. It is sometimes desirable, and necessary when using more than one unit on a single RS232 line, to be able to poll the unit.

In Polling Mode the unit measures the flow normally, but only sends a line of data when it is “polled”. Each unit can be given its own unique identifier or address. Unless otherwise specified each unit is shipped with a default address of capital A. Other valid addresses are B thru Z.

Once you have established communication with the unit and have a stream of information filling your screen:

1. Type *@=A followed by “Enter” (or using the RS232 communication select menu, select A as identifier and exit the screen) to stop the streaming mode of information. Note that the flow of information will not stop while you are typing and you will not be able to read what you have typed. Also, the unit does not accept a backspace or delete in the line so it must be typed correctly. If in doubt, simply hit enter and start again. If the unit does not get exactly what it is expecting, it will ignore it. If the line has been typed correctly, the data will stop.

2. You may now poll the unit by typing A followed by “Enter”. This does an instantaneous poll of unit A and returns the values once. You may type A “Enter” as many times as you like. Alternately you could resume streaming mode by typing *@=@ followed by “Enter”. Repeat step 1 to remove the unit from the streaming mode.

3. To assign the unit a new address, type *@=New Address, e.g. *@=B. Care should be taken not to assign an address to a unit if more than one unit is on the RS232 line as all of the addresses will be reassigned. Instead, each should be individually attached to the RS232 line, given an address, and taken off. After each unit has been given a unique address, they can all be put back on the same line and polled individually.

Gas Select – The selected gas can be changed via RS232 input. To change the selected gas, enter the following commands:

In Polling Mode: Address$$#<Enter> (e.g. B$$#<Enter>)

Where # is the number of the gas selected from the table below. Note that this also corresponds to the gas select menu on the flow meter screen (the Standard gas category is shown in the example below):

Creating and Deleting Gas Mixtures with Composer using RS232Note: All commands must be prefixed with the unit ID if the unit is not in streaming mode.You may create and store up to 20 gas mixtures containing up to five constituent gases each. Create a Gas MixtureTo create a gas mixture, enter a single-line command according to the following formula: [Unit ID]GM [Gas Name] [Gas Mix Number] [Percent 1] [Gas Number 1] [Percent 2] [Gas Number 2] …

Gas Name: Name your mixture using a maximum of 6 characters. Gas Mix Number: Composer user mixes have gas numbers between 236 and 255. You can assign any number in this range to your new mixture. If another mixture with the same number exists, it will be overwritten, even if that gas is currently selected on the unit. If you enter a 0 here, the new mix will be assigned the next available number between 236 and 255. Percent 1: The percentage of the first constituent gas. The percentage of each constituent must be between 0.01 and 99.99. Values entered beyond two decimal points will be rounded to the nearest 0.01%.Gas Number 1: The gas number of the first constituent gas.Percent 2: The percentage of the first constituent gas. Values entered beyond two decimal points will be rounded to the nearest 0.01%.Gas Number 2: The gas number of the first constituent gas.Additional Gases: (Optional) The above pattern of [Percent] + [Gas Number] may be repeated for additional constituent gases up to a total of 5 constituents. The sum of all percentages must be 100.00.

On success, the unit ID (if set) is returned followed by a space. The number of the gas mixture is then returned, followed by the percentages and names of each constituent in the mix. If the gas is not successfully mixed, a "?" is returned.Delete a Gas MixtureTo delete a gas mixture, enter:

[Unit ID]GD [Gas Number]: The number of the Composer user mixture you wish to delete from the unit

Only Composer user mixtures can be deleted with this command.On success, the unit ID (if set) is returned followed by a space and the number of the gas deleted. If the gas is not successfully deleted, a "?" is returned.

Data Format:The data stream on the screen represents the flow parameters of the main mode in the units shown on the display. For mass flow meters, there are five columns of data representing pressure, temperature, volumetric flow, mass flow and the selected gas. The first column is absolute pressure (normally in psia), the second column is temperature (normally in °C), the third column is volumetric flow rate (in the units specified at time of order and shown on the display), and the fourth column is mass flow (also in the units specified at time of order and shown on the display). For instance, if the meter was ordered in units of scfm, the display on the meter would read 2.004 scfm and the last two columns of the output below would represent volumetric flow and mass flow in cfm and scfm respectively.

FMA-1600A Mass Flow Meter Data FormatNote: On units with the totalizer function the fifth column will be the totalizer value, with gas select moving to a sixth column.

Collecting Data:The RS232 output updates to the screen many times per second. Very short-term events can be captured simply by disconnecting (there are two telephone symbol icons at the top of the HyperTerminal® screen for disconnecting and connecting) immediately after the event in question. The scroll bar can be driven up to the event and all of the data associated with the event can be selected, copied, and pasted into Microsoft® Excel® or other spreadsheet program as described below.For longer term data, it is useful to capture the data in a text file. With the desired data streaming to the screen, select “Capture Text” from the Transfer Menu. Type in the path and file name you wish to use. Push the start button. When the data collection period is complete, simply select “Capture Text” from the Transfer Menu and select “Stop” from the sub-menu that appears.Data that is selected and copied, either directly from HyperTerminal® or from a text file can be pasted directly into Excel®. When the data is pasted it will all be in the selected column. Select “Text to Columns...” under the Data menu in Excel® and a Text to Columns Wizard (dialog box) will appear. Make sure that “Fixed Width” is selected under Original Data Type in the first dialog box and click “Next”. In the second dialog box, set the column widths as desired, but the default is usually acceptable. Click on “Next” again. In the third dialog box, make sure the column data format is set to “General”, and click “Finish”. This separates the data into columns for manipulation and removes symbols such as the plus signs from the numbers. Once the data is in this format, it can be graphed or manipulated as desired. For extended term data capture see page 26

Sending a Simple Script File to HyperTerminal®It is sometimes desirable to capture data for an extended period of time. Standard streaming mode information is useful for short term events, however, when capturing data for an extended period of time, the amount of data and thus the file size can become too large very quickly. Without any special programming skills, you can use HyperTerminal® and a text editing program such as Microsoft® Word® to capture text at defined intervals.1. Open your text editing program, MS Word for example.2. Set the cap lock on so that you are typing in capital letters.3. Beginning at the top of the page, type A<Enter> repeatedly. If you’re using MS Word, you can tell how many lines you have by the line count at the bottom of the screen. The number of lines will correspond to the total number of times the flow device will be polled, and thus the total number of lines of data it will produce.For example: A

A A A A Awill get a total of six lines of data from the flow meter, but you can enter as many as you like.

The time between each line will be set in HyperTerminal.4. When you have as many lines as you wish, go to the File menu and select save. In the save dialog box, enter a path and file name as desired and in the “Save as Type” box, select the plain text (.txt) option. It is important that it be saved as a generic text file for HyperTerminal to work with it.5. Click Save.6. A file conversion box will appear. In the “End Lines With” drop down box, select CR Only. Everything else can be left as default.7. Click O.K.8. You have now created a “script” file to send to HyperTerminal. Close the file and exit the text editing program.9. Open HyperTerminal and establish communication with your flow device as outlined in the manual.10. Set the flow device to Polling Mode as described in the manual. Each time you type A<Enter>, the meter should return one line of data to the screen.11. Go to the File menu in HyperTerminal and select “Properties”.12. Select the “Settings” tab.13. Click on the “ASCII Setup” button.

14. The “Line Delay” box is defaulted to 0 milliseconds. This is where you will tell the program how often to read a line from the script file you’ve created. 1000 milliseconds is one second, so if you want a line of data every 30 seconds, you would enter 30000 into the box. If you want a line every 5 minutes, you would enter 300000 into the box.15. When you have entered the value you want, click on OK and OK in the Properties dialog box.16. Go the Transfer menu and select “Send Text File…” (NOT Send File…).17. Browse and select the text “script” file you created.18. Click Open.19. The program will begin “executing” your script file, reading one line at a time with the line delay you specified and the flow device will respond by sending one line of data for each poll it receives, when it receives it.You can also capture the data to another file as described in the manual under “Collecting Data”. You will be simultaneously sending it a script file and capturing the output to a separate file for analysis.

Operating Principle

All FMA-1600A Gas Flow Meters and FMA-2600A Gas Flow Controllers are based on the accurate measurement of volumetric flow. The volumetric flow rate is determined by creating a pressure drop across a unique internal restriction, known as a Laminar Flow Element (LFE), and measuring differential pressure across it. The restriction is designed so that the gas molecules are forced to move in parallel paths along the entire length of the passage; hence laminar (streamline) flow is established for the entire range of operation of the device. Unlike other flow measuring devices, in laminar flow meters the relationship between pressure drop and flow is linear.

STANDARD GAS DATA TABLES: Those of you who have older Omega products (manufactured before October 2005) may notice small discrepancies between the gas property tables of your old and new units. Omega has incorporated the latest data sets from NIST (including their REFPROP 7 data) in our products’ built-in gas property models. Be aware that the calibrators that you may be using may be checking against older data sets such as the widely distributed Air Liquide data. This may generate apparent calibration discrepancies of up to 0.6% of reading on well behaved gases and as much as 3% of reading on some gases such as propane and butane, unless the standard was directly calibrated on the gas in question. As the older standards are phased out, this difference in readings will cease to be a problem. If you see a difference between the Omega meter and your in-house standard, in addition to calling Omega, call the manufacturer of your standard for clarification as to which data set they used in their calibration. This comparison will in all likelihood resolve the problem.

TROUBLESHOOTING

Display does not come on or is weak.Check power and ground connections.

Flow reading is approximately fixed either near zero or near full scale regardless of actual line flow.Differential pressure sensor may be damaged. Avoid installations that can subject sensor to pressure drops in excess of 10 psid. A common cause of this problem is instantaneous application of high-pressure gas as from a snap acting solenoid valve upstream of the meter. If you suspect that your pressure sensor is damaged please discontinue use of the meter and contact Omega.

Displayed mass flow, volumetric flow, pressure or temperature is flashing and message MOV, VOV, POV or TOV is displayed:Our flow meters and controllers display an error message (MOV = mass overrange, VOV = volumetric overrange, POV = pressure overrange, TOV = temperature overrange) when a measured parameter exceeds the range of the sensors in the device. When any item flashes on the display, neither the flashing parameter nor the mass flow measurement is accurate. Reducing the value of the flashing parameter to within specified limits will return the unit to normal operation and accuracy. If the unit does not return to normal contact Omega.

Meter reads negative flow when there is a confirmed no flow condition.This is an indication of an improper tare. If the meter is tared while there is flow, that flow is accepted as zero flow. When an actual zero flow condition exists, the meter will read a negative flow. Simply re-tare at the confirmed zero flow condition. Also note that while the meter is intended for positive flow, it will read negative flow with reasonable accuracy, but not to the full scale flow rate (it is not calibrated for bi-directional flow) and no damage will result.

Meter does not agree with another meter I have in line.Volumetric meters are affected by pressure drops. Volumetric flow meters should not be compared to mass flow meters. Mass flow meters can be compared against one another provided there are no leaks between the two meters and they are set to the same standard temperature and pressure. Both meters must also be calibrated (or set) for the gas being measured. FMA-1600A mass flow meters are normally set to Standard Temperature and Pressure conditions of 25° C and 14.696 psia. Note: it is possible to special order meters with a customer specified set of standard conditions. The calibration sheet provided with each meter lists its standard conditions. When performing this comparison it is best to use the smallest transition possible between the two devices. Using small transitions will minimize lag and dead volume.

Flow flutters or is jumpy.The meters are very fast and will pick up any actual flow fluctuations such as from a diaphragm pump, etc. Also, inspect the inside of the upstream connection for debris such as PTFE tape shreds. Note: FMA-PC1600 meters feature a programmable geometric running average (GRA) that can aid in allowing a rapidly fluctuating flow to be read (see “Pressure Averaging” and “Flow Averaging” page 16).

The output signal is lower than the reading at the display.This can occur if the output signal is measured some distance from the meter, as voltage drops in the wires increase with distance. Using heavier gauge wires, especially in the ground wire, can reduce this effect.

RS232 Serial Communications is not responding.Check that your meter is powered and connected properly. Be sure that the port on the computer to which the meter is connected is active. Confirm that the port settings are correct per the RS232 instructions in this manual (Check the RS232 communications select screen for current meter readings). Close Hyperterminal® and reopen it. Reboot your PC. See pages 20 - 26 for more information on RS232 signals and communications.

Slower response than specified.FMA-PC1600 Meters feature a programmable Geometric Running Average (GRA). Depending on the full scale range of the meter, it may have the GRA set to enhance the stability/readability of the display, which would result in slower perceived response time. Please see “Pressure Averaging” and “Flow Averaging” on page 16.

Jumps to zero at low flow.FMA-PC1600 Meters feature a programmable zero deadband. The factory setting is usually 0.5% of full scale. This can be adjusted between NONE and 6.3% of full scale. See page 16.

Discrepancies between old and new units.Please see “Standard Gas Data Tables” explanation on page 27.

Maintenance and Recalibration

General: Portable Calibration Units require minimal maintenance. They have no moving parts. The single most important thing that affects the life and accuracy of these devices is the quality of the gas being measured. The meters are designed to measure CLEAN, DRY, NON-CORROSIVE gases.

Moisture, oil and other contaminants can affect the laminar flow elements.

Recalibration: The recommended period for recalibration is once every year. A label located on the FMA-PC1600 lists the most recent calibration date. The FMA-PC1600 should be returned to the factory for recalibration within one year from the listed date. Before calling to schedule a recalibration, please note the serial number on the back of the meter. The Serial Number, Model Number, and Date of Manufacture are also available on the Model Info display (page 19).

Cleaning: FMA-PC1600 meters require no periodic cleaning. If necessary, the outside of the meter can be cleaned with a soft dry cloth. Avoid excess moisture or solvents.

For repair, recalibration or recycling of this product contact Omega

Option: Totalizing Mode - MetersMeters can be purchased with the Totalizing Mode option. This option adds an additional mode screen that displays the total flow (normally in the units of the main flow screen) that has passed through the device since the last time the totalizer was cleared. The Totalizing Mode screen is accessed by pushing the TOTAL/TIMER button on the MAIN display.

TOTAL/TIMER: Pushing the TOTAL/TIMER button will cycle the large numbers on the display between total mass and time elapsed.Rollover – The customer can also specify at the time of order what the totalizer is to do when the maximum count is reached. The following options may be specified:No Rollover – When the counter reaches the maximum count it stops counting until the counter is cleared.Rollover – When the counter reaches the maximum count it automatically rolls over to

zero and continues counting until the counter is cleared.Rollover with Notification – When the counter reaches the maximum count it automatically rolls over to zero, displays an overflow error, and continues counting until the counter is cleared.TOTAL MASS: The counter can have as many as seven digits. At the time of order, the customer must specify the range. This directly affects the maximum count. For instance, if a range of 1/100ths of a liter is specified on a meter which is totalizing in liters, the maximum count would be 99999.99 liters. If the same unit were specified with a 1 liter range, the maximum count would be 9999999 liters.ELAPSED TIME: The small numbers below the mass total show the elapsed time since the last reset in hours, minutes and seconds. The maximum measurable elapsed time is 9999 hours 59 minutes 59 seconds. The hours count resets when RESET is pushed, an RS232 clear is executed or on loss of power. Press TOTAL/TIMER to show this as the primary display.SETPT: Pushing SETPT will allow you to change the controller's set-point.RESET – The counter can be reset to zero at any time by pushing the RESET button. To clear the counter via RS232, establish serial communication with the meter or controller as described in the RS232 or RS-485 section of the manual. To reset the counter, enter the following commands:
