Introduction
The PROVU® PD6363 is a multipurpose, easy to use digital dual pulse input rate/totalizer ideal for
flow rate, total, and flow control applications. Its superluminous LED digits make it easily readable
in smoke, dust, fog, and, with the optional SunBright® display, even direct sunlight.
It accepts two pulse (e.g. 40 mVp-p to 8 Vp-p), square wave (0-5 V, 0-12 V, or 0-24 V), open
collector, NPN, PNP, TTL or switch contact signals. Various math functions may be applied to the
rate, total, or grand totals of the two channels; including addition, difference, average, minimum,
maximum, draw, ratio and more.
The displays, relays, and the analog output may be assigned to the rate, total, or grand total of
input channels A or B; or math result channel C. Three of the front panel buttons can be customprogrammed for a specific operation.
The basic model includes an isolated 24 VDC transmitter power supply that can be used to power
the input transmitters or other devices. An additional isolated 24 VDC power supply is included
with the 4-20 mA output option. A digital input is standard.
Meter capabilities may be enhanced with external expansion modules. External serial
communication adapters are also available for use with MeterView Pro or Modbus RTU.

WARNING!
Hazardous voltages exist within enclosure. Installation and
service should be performed only by trained service personnel.
Installation
There is no need to remove the meter from its case to complete the installation, wiring, and setup
of the meter for most applications.
Instructions are provided for changing the transmitter power supply to output 5 or 10 VDC instead
of 24 VDC, see page 11.
Unpacking
Remove the meter from box. Inspect the packaging and contents for damage. Report damages, if
any, to the carrier.
If any part is missing or the meter malfunctions, please contact your supplier or the factory for
assistance.
Panel Mounting Instructions
Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x 45 mm). Refer to Figure 1
below, for more details.
Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.
Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
Remove the two mounting brackets provided with the meter (back-off the two screws so that there is ¼"
(6.4 mm) or less through the bracket. Slide the bracket toward the front of the case and remove).
Insert meter into the panel cutout.
Install mounting brackets and tighten the screws against the panel. To achieve a proper seal, tighten
the mounting bracket screws evenly until meter is snug to the panel along its short side. DO NOT
OVER TIGHTEN, as the rear of the panel may be damaged.
All meters, including models equipped with the 12-24 VDC power option, are shipped from the factory
configured to provide 24 VDC power for the transmitter or sensor.
If the transmitter requires 5 or 10 VDC excitation, the internal jumper J4 must be configured
accordingly.
To access the voltage selection jumper:
1. Remove all the wiring connectors.
2. Unscrew the back cover.
3. Slide out the back cover by about 1 inch.
4. Configure the J4 jumper, located behind the input signal connector, for the desired excitation
voltage as shown.
All connections are made to removable screw terminal connectors located at the rear of the meter.
Use copper wire with 60°C or 60/75°C insulation for all line
voltage connections. Observe all safety regulations.
Electrical wiring should be performed in accordance with all
applicable national, state, and local codes to prevent

Switching Inductive Loads
The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the
microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Suppression can be obtained
with resistor-capacitor (RC) networks assembled by the user or purchased as complete assemblies. Refer to the
following circuits for RC network assembly and installation:
C
C
R
R
Figure 15. AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 Ω for each volt across the contacts
C: 0.5 to 1 µF for each amp through closed contacts
Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check to confirm proper operation.
3. Install the RC network at the meter's relay screw terminals. An RC network may also be installed
across the load. Experiment for best results.
Use a diode with a reverse
breakdown voltage two to three
times the circuit voltage and
forward current at least as large
as the load current.
RC networks are available from Precision Digital and should be applied to each relay contact switching an
inductive load. Part number: PDX6901.
Note: Relays are de-rated to 1/14th HP (50 watts) with an inductive load.
F4 Digital Input Connections
A digital input, F4, is standard on the meter. This digital input connected with a normally open closure
across F4 and COM, or with an active low signal applied to F4.

Interlock Relay Feature
As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as
interlock relay(s). Interlock contact(s) are wired to digital input(s) and trigger the interlock relay. This
feature is enabled by configuring the relay, and relative digital input(s) (see page 39). In one example, dry
interlock contacts are connected in series to one digital input which will be used to force on (energize) the
assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front
panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O
contact). See below.
The meter has been factory calibrated to read input frequency in Hz (pulses/sec). The calibration
equipment is certified to NIST standards.
Use the K-Factor menu to match the rate/totalizer with a flowmeter’s k-factor (pulse/unit of measure).
Or use the Scale menu to scale the pulse input (pulse/sec) without a signal source.
Or use Cal menu to calibrate the rate/totalizer using a signal source.

Setting the Decimal Point (dEc pt)
The decimal point for any channel, rate, total, or grand total, may be set with up to five decimal places or
with no decimal point at all.
Pressing the Right arrow moves the
decimal point one place to the right
until no decimal point is displayed, and
then it moves to the leftmost position.
Pressing the Up arrow moves the
decimal point one place to the left.
There are seven decimal points to set
up for three channels: Ch-A rate, total,
and grand total; Ch-B rate, total, and
grand total; and Ch-C.
After the decimal points are set up, the
meter moves to the Program menu.
It is very important that one reads the following information before programming the meter:
The meter has been factory calibrated to read input frequency in Hz (pulses/sec). The calibration
equipment is certified to NIST standards.
Use the K-Factor menu to match the rate/totalizer with a flowmeter’s k-factor (pulse/unit of measure).
Or use the Scale menu to scale the pulse input (pulse/sec) without a signal source.
Or use Cal menu to calibrate the rate/totalizer using a signal source.
The Program menu contains the following menus for each channel A and B:
1. K-Factor calibration
2. Scale without a signal source
3. Calibrate with a calibrated signal source
4. Total time base & conversion factor
5. Grand total time base & conversion factor
6. Reset modes for total & grand total
The pulse inputs may be calibrated or scaled to any display value within the range of the meter.
Additional parameters, not needed for most applications, are found in the Advanced Features menu; see
Advanced Features Menu, page 42.
Input Calibration Method (InCAL)
There are three methods of calibrating (or scaling) the display for each input channel to show the correct
engineering units.
Use the Factor menu to enter the k-factor of a flowmeter in units/pulse
Use the Scale menu to enter the scaling without a signal source.
Use the Calibrate menu to apply a signal from a signal source.
Note: The Scale, Calibrate, and K-Factor functions are exclusive of each other. The meter uses the last
function programmed. Only one of these methods can be employed at a time.
Multi-Point Calibration & Scaling
The Scale and Calibrate functions can use up to 32 points (default is 2). The number of points should be
set in the Advanced menu under the Multi-Point Linearization (Linear) menu selection prior to scaling and
calibration of the meter, see page 46 for details.
K-Factor Calibration (Fact-A, Fact-b)
The meter may be calibrated using the K-Factor function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor (Fact-A, Fact-b) menu and select the decimal point with
highest resolution possible and program the k-factor value (i.e. pulses/gal). The meter will automatically
calculate the flow rate using the k-factor and the time base selected.
Scaling the Meter without a Signal Source (SCAL-A, SCAL-B)
The inputs can be scaled to display the process variables in engineering units.
A signal source is not needed to scale the meter; simply program the inputs and corresponding display
values.
From the INCAL menu, select channel A or B, followed by SCal-A or SCal-B, and then set the signal input
value and display value for each of the scaling points (default is two). Enter the signal input values in
pulses/second (Hz), and the corresponding display values in appropriate engineering units. Channel B is
scaled similarly to Channel A, shown below.
Scaling the Meter for Channel A (SCal-A)
“Saved” displays

prior to
Channel B
For instructions on how to program numeric values see
Setting Numeric
Values, page 23.
Note: The display values (DiS 1 and DiS 2) need to be in units of measure per second.
For example: If the rate at 1000 Hz is 13.2 gal/min, this must be converted to gal/sec. In this scenario,
the numbers input into the SCALE menu would be as follows:
Set the time base set to minutes (see page 30) and the meter will display 13.2 gal/min at
1000 Hz
Error Message (Error)
An error message indicates that the calibration or scaling process was not successful.
After the error message is displayed, the meter reverts to input 2 during calibration or scaling and to input
1 during internal calibration, allowing the appropriate input signal to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards.
2. Minimum input span requirements not maintained.
3. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum allowed input span is 1.0 Hz, which is the minimum difference between input 1 and input 2
signals required to complete the calibration or scaling of the meter.
Calibrating the Meter with External Source (CAL-A, CAL-B)
To scale the meter without a signal source, refer to Scaling the
Meter without a Signal Source (SCAL-A, SCAL-B), page 28.
Warm up the meter for at least 15 minutes before performing
calibration to ensure specified accuracy.
The meter can be calibrated to display the process variables in engineering units by applying the
appropriate input signal and following the calibration procedure.
The use of a calibrated signal source is strongly recommended to calibrate the meter.
Channel B is calibrated similarly to Channel A, shown below.
Calibrating the Meter for Channel A (CAL-A)
Note: The display values (DiS 1 and DiS 2) need to be in units of measure per second.
The time base and total and grand total conversion factors for input channels A and B are located in the
Totalizer Setup menu.
The time base is determined by the rate programming. Enter the time unit of the programmed rate scale.
For example: A rate display scaled in engineering units of gallons per minute would use a time base of
minutes.
Total & grand total conversion factors for channel A and B are programmed independently. This means
that one total or grand total can be displaying the value in gallons while another displays in million
gallons, liters, m
3
, etc.
Total & Grand Total Reset (treset)
Total reset menus are located in the Program menu. The totals can be programmed for manual or
automatic reset. In the automatic reset mode, a programmable time delay (t dly) in seconds is available
to reset the total or grand total after the assigned preset is reached.
Setting the Display Parameters & Intensity (dsplay)
Display line 1 (line 1) can be programmed to display:

Notes: The sum of total A and B for t ABC is independent of channel C programming. Channel C may be
used normally by a different display selection even when D tABC is selected for one of the two displays.
25. Modbus input (nm bus)
Display line 2 (Line 2) can be programmed to display:
1. All options for display line 1
2. Off, with no display (d ofF)
3. Engineering units for any single channel, total, or grand to
Display Intensity: The meter has eight display intensity levels to give the best performance under
various lighting conditions. Select intensity 8 for outdoor applications. The default intensity setting is 8.
After setting up the input and display, press the Menu button to exit programming and skip the rest of the
setup menu.
Operation of the relays is programmed in the Action
menu. The relays may be set up for any of the
following modes of operation:
1. Automatic reset (non-latching)
2. Automatic + manual reset at any time (non-latching)
3. Latching (manual reset only, at any time)
4. Latching with Clear (manual reset only after alarm condition has cleared)
5. Pump alternation control (automatic reset only)
6. Sampling (the relay is activated for a user-specified time)
7. Off (relay state controlled by Interlock feature)
The following graphic shows relay 1 action setup; relay 2-8 are set up in a similar fashion.
Programming Set and Reset Points
High alarm indication: program set point above reset point.
Low alarm indication: program set point below reset point.
The deadband is determined by the difference between set and reset
points. Minimum deadband is one display count. If the set and reset
points are programmed with the same value, the relay will reset one
count below the set point.
Note: Changes are not saved until the reset point has been accepted.
Setting Fail-Safe Operation
In fail-safe mode of operation, the relay coil is energized when the process variable is within safe limits
and the relay coil is de-energized when the alarm condition exists. The fail-safe operation is set
independently for each relay. Select on to enable or select off to disable fail-safe operation.
Programming Time Delay
The On and Off time delays may be programmed for each relay between 0 and 999.9 seconds. The
relays will transfer only after the condition has been maintained for the corresponding time delay.
The On time delay is associated with the set point.
The Off time delay is associated with the reset point.
The following graphs illustrate the operation of the relays, status LEDs, and ACK button.
High Alarm Operation (Set > Reset)
For Manual reset mode, ACK can be pressed anytime
to turn "off" relay. To detect a new alarm condition, the
signal must go below the set point, and then go above
it.
Low Alarm Operation (Set < Reset)
For Manual reset mode, ACK can be pressed anytime
to turn "off" relay. For relay to turn back “on”, signal
must go above set point and then go below it.
High Alarm with Fail-Safe
Operation (Set > Reset)
Note: Relay coil is energized in non-alarm
condition. In case of power failure, relay will
go to alarm state.
Low Alarm with Fail-Safe Operation
(Set < Reset)
Note: Relay coil is energized in non-alarm
condition. In case of power failure, relay will
go to alarm state.
When the signal crosses the set point, the relay trips and the sample time starts. After the sample time
has elapsed, the relay resets. The cycle repeats every time the set point is crossed, going up for high
alarms and going down for low alarms.
The sample time can be programmed between 0.1 and 5999.9 seconds.
When the total reaches the preset, the relay trips and the sample time starts. After the sample time has
elapsed, the relay resets. The cycle repeats every time the preset value is added to the total.
Time Delay Operation
The following graphs show the operation of the time delay function.
When the signal crosses the set point, the On time delay timer starts and the relay trips when the time
delay has elapsed. If the signal drops below the set point (high alarm) before the time delay has elapsed,
the On time delay timer resets and the relay does not change state. The same principle applies to the Off
time delay.
Note: If “Automatic or Manual (A-mAn)” reset mode is selected, the LED follows the reset point and not
The relay capabilities of the meter expand its usefulness beyond simple indication to provide users with
alarm and control functions. These capabilities include front panel alarm status LEDs as well as either 2
or 4 optional internal relays and/or 4 external relays expansion module. Typical applications include high
or low temperature, level, pressure or flow alarms, control applications such as simple on/off pump
control, and pump alternation control for up to 8 pumps. There are four basic ways the relays can be
used:
1. High or Low Alarms with Latching or Non-Latching Relays
2. Simple On/Off Control with 100% Adjustable Deadband
3. Sampling (Based on Time)
4. Pump Alternation Control for up to 8 Pumps
Relays Auto Initialization
When power is applied to the meter,
the front panel LEDs and alarm relays
will reflect the state of the input to the
meter. The following table indicates
how the alarm LEDs and relays will
react on power-up based on the set
and reset points.

Front Panel LEDs
The LEDs on the front panel provide status indication for the following:
The meter is supplied with four alarm points that include front
panel LEDs to indicate alarm conditions. This standard feature
is particularly useful for alarm applications that require visualonly indication. The LEDs are controlled by the set and reset
points programmed by the user. When the display reaches a
set point for a high or low alarm, the corresponding alarm LED will turn on. When the display returns to
the reset point the LED will go off. The front panel LEDs responds differently for latching and non-latching
relays.
For non-latching relays, the LED is always off during normal condition and always on during alarm
condition, regardless of the state of the relay (e.g. Relay acknowledged after alarm condition).
For latching relays, the alarm LEDs reflects the status of the relays, regardless of the alarm condition. The
following tables illustrate how the alarm LEDs function in relation to the relays and the acknowledge
button (Default: F3 key assigned to ACK).
The relays can be set up for latching (manual reset) or
non-latching (automatic reset) operation.
The On and Off terminology does not refer to the status of
the relay’s coil, which depends on the fail-safe mode
selected.
In latching relay mode, latched

The next time an alarm occurs, the operator acknowledges
the alarm manually while the alarm condition still exists.
This causes the relay to reset, but the LED stays on until

Latching Relay (Lt-Clr)
In this application, the meter is set up for manual reset only
after the signal passes the reset point (alarm condition has
cleared). Acknowledging the alarm while it is still present has
no effect on either the LED or the relay. When the alarm is
acknowledged after it returns to the normal state, the LED
and the relay go off. Notice that the LED remains on, even
after the meter returns to the normal condition. This is
because, for latching relays, the alarm LED reflects the
status of the relay, regardless of the alarm condition.
There are two ways to acknowledge relays programmed for manual reset:
1. Via the programmable front panel function keys F1-F3 (Default:
F3 assigned to ACK).
2. Remotely via a normally open pushbutton wired across one of the digital inputs and the +5 V
terminals on the digital I/O modules, or using the F4 digital input, which is triggered with a contact
closure to COM, or with an active low signal (see page 15).
When the ACK button or the assigned digital input is closed, all relays programmed for manual reset are
acknowledged.

Setting Up the Interlock Relay (Force On) Feature
Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:
1. Access the Setup – Relay – Action menu and set the action to off.
2. In the Advanced features – User menu program any of the digital inputs to Force On any of the
internal relays (1-4).
3. Connect a switch or dry contact between the +5V terminal and the corresponding digital input (dI-1 to
dI-4) terminal.
Note: If multiple digital inputs are assigned to the same relay, then the corresponding logic is (AND) – i.e.
both switches must be closed to trip the relay.
Scaling the 4-20 mA Analog Output (Aout)
The 4-20 mA analog outputs can be scaled to provide a 4-20 mA signal for any display range selected.
To select the channel and source assignments the analog outputs are assigned to, see Analog Output Source on page 49.
No equipment is needed to scale the analog outputs; simply program the display values to the
corresponding mA output signal.
The Analog Output menu is used to program the 4-20 mA outputs based on display values.
The Reset menu is used to reset the maximum (peak) value of Ch-A and Ch-B rate (rst Hi), minimum
(valley) reading of Ch-A and Ch-B rate (rst Lo), both high and low value of Ch-A and Ch-B rate (rst HL), Ch-A total (tot A) or Ch-B total (tot B), Ch-A grand total (Gtot A) or Ch-B grand total (Gtot B),
both Ch-A and Ch-B totals (tot AB), or both Ch-A and Ch-B grand totals (Gt AB).
Control Menu (Contrl)
The Control menu is used to control the 4-20 mA analog output (Aout 1 only) and the relays manually,
ignoring the input. Each relay and analog output can be programmed independently for manual control.
Selecting automatic control sets all relays and analog output for automatic operation.
Once Manual mode is initiated on any relay or
analog output, an LED labeled “M” is turned
on. Every few seconds, all LEDs representing
outputs that are in Manual mode, as well as
the “M” LED flash. Thi s proce ss w il l co ntin ue
as long as any output is in manual mode.
Setting Up the Password (pass)
The Password menu is used for programming three levels of security to prevent unauthorized changes to
the programmed parameter settings, to restrict the ability to reset the totals and grand totals, and to
program the non-resettable totalizer.
Pass 1: Allows use of function keys and digital inputs
Pass 2: Allows use of function keys, digital inputs and editing set/reset points
Pass 3: Restricts all programming, function keys, and digital inputs.
Total: Prevents resetting the total manually
Gtotal: Prevents resetting the grand total manually
Protecting or Locking the Meter Functions
Enter the Password menu and program a six-digit password.
For instructions on how to program numeric values see
The total and the grand total can be password-protected to prevent unauthorized total resets.
The grand total can be programmed as a non-resettable total by entering the password “050873”.
!
Caution!
Once the Grand Total has been programmed as
“non-resettable” the feature cannot be disabled.
Making Changes to a Password Protected Meter
If the meter is password protected, the meter will display the message Locd (Locked) when the Menu
button is pressed. Press the Enter button while the message is being displayed and enter the correct
password to gain access the menu. After exiting the programming mode, the meter returns to its
password protected condition.
Disabling Password Protection
To disable the password protection, access the Password menu and enter the correct password twice, as
shown below. The meter is now unprotected until a new password is entered.
If the correct six-digit password is entered, the meter displays the message unLoc (unlocked) and the
protection is disabled until a new password is programmed.
If the password entered is incorrect, the meter displays the message Locd (Locked) for about two
seconds, and then it returns to Run Mode. To try again, press Enter while the Locked message is
displayed.
Did you forget the password?
The password may be disabled by entering a
master password once. If you are authorized
to make changes, enter the master password
508655 to unlock the meter.
The gate function (Gate) is the first option in the Advanced Features menu. There are two settings for the
Gate, low gate (Lo G) and high gate (Hi G). Channel A and B use the same gate settings.
The gate function is used for displaying slow pulse rates. Using the programmable gate, the meter is able
to display pulse rates as slow as 1 pulse every 999.9 seconds (0.001 Hz). The gate function can also be
used to obtain a steady display reading with a fluctuating input signal.
Low Gate (Lo G)
For most applications, low gate setting should be left at 1.0 second. Increase low gate setting to obtain a
steadier rate display. The rate display will update in accordance with the low gate setting, for example if
low gate is set at 10.0, the display will update every 10 seconds; changes in rate between updates will not
be reflected until next display update.
High Gate (Hi G)
Set the high gate value to correspond to the highest expected pulse period (lowest pulse rate). For
instance if the meter must display a rate when there is 1 pulse coming into the meter every 10 seconds,
set the high gate to 11.0 seconds. When the signal is removed from the meter, the display will show the
last reading for 11 seconds; then it will read zero.
Gate Settings

1.0 400.0 0.0025
1.0 800.0 0.0012
1.0 999.9 0.0010
*The low gate setting corresponds to the display update rate
and is used to stabilize the display reading with a fluctuating
signal.
**The minimum frequency is dependent on high gate
setting.
The filter function (Filter) is the second option in the Advanced Features menu. The filter function
(FiLter) can be used for applications where the meter is set up to count pulses generated by switch
contacts. The filter value can be set anywhere between 2 and 50, the higher the value, the greater the
filtering. Channel A and B have independent settings.
There are two settings, Hi SPd (high speed) and Lo SPd (low speed). After pressing ENTER to select LoSPd, enter the desired filter setting based on the table below so that there are no extra counts when a
contact closure is completed. Selecting Hi SPd does not require a programmable filter value.

Rounding Feature (round)
The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used
in addition to the filter function.
Rounding causes the display to round to the nearest value according to the rounding selected. This
setting affects the last two digits, regardless of decimal point position.
Modbus RTU Serial Communications (serial)
The meter is equipped with serial communications capability as a standard feature using Modbus RTU
Serial Communication Protocol.
The meter may be connected to a PC for initial configuration via the onboard micro USB connection. For
ongoing digital communications with a computer or other data terminal equipment, an RS-232, or RS-485
option is required; see Ordering Information on page 5 for details.
Do not connect any equipment other than Precision

Changes made to the Serial menu are initialized after the MENU key is pressed or after navigating
through the t-byte parameter.
The Select menu is used to select the signal input conditioning function applied to the inputs, math
function for A & B, constants, low-flow cutoff, total count direction (up or down from a preset amount), and
analog output programming. Multi-point linearization is part of the linear function selection.
Signal Input Conditioning (Functn)
The Function menu is used to condition the linear input signal. Multi-point linearization is part of the linear
function selection. Each input channel signal input conditioning function is programmed independently.
Multi-Point Linearization (Linear)
Meters are set up at the factory for linear function with 2-point linearization. Up to 32 linearization points
can be selected for each channel under the linear function. The multi-point linearization can be used to
linearize the display for non-linear signals such as those from level transmitters used to measure volume
in odd-shaped tanks or to convert level to flow using weirs and flumes with complex exponent.
Note: After Scale is displayed continue pressing the Enter button until the meter completes the
The Math menu is used to select the math function that will determine the channel C value. These math
functions are a combination of input channels A and B, and will display when channel C is selected in the
Display menu.
A and B refer to the rate of channel A and B. tA and tB refer to the totals of channel A and B. GtA and
GtB refer to the grand totals of channel A and B. The following math functions are available.

Math Constants (Const)
The Math Constants menu is used to set the constants used in channel C math. The math functions
include adder constant P, and factor constant F.
The Adder constant (P) may be set from -99.999 to 999.999.
The Factor constant (F) may be set from 0.001 to 999.999.
The chart on page 47 details the math functions that may be selected in the Math Function menu.
The low-flow cutoff feature allows the meter to be programmed so that the often-unsteady output from a
differential pressure transmitter, at low flow rates, always displays zero on the meter. The low-flow cutoff
for each channel is programmed independently.
The cutoff value may be programmed from 0 to 999999. The meter will display zero below the cutoff
value. Programming the cutoff value to zero disables the cutoff feature.
Totalizer Count Up/Down (Count)
The totalizer count up/down menu may be used to program the total and grand total to either count up
from 0 when reset or count down from a programmed value when reset. Total and grand total may have
their countdown numbers programmed individually from 0 to 999999.
Analog Output Programming (AoutPr)
The Analog Output Programming menu is used to program the behavior of the 4-20 mA outputs. The
following parameters and functions are programmed in this menu for each analog output:
1. Source: Source for generating the 4-20 mA output
2. Overrange: Analog output value with display in overrange condition
3. Underrange: Analog output value with display in underrange condition
4. Max: Maximum analog output value allowed regardless of input
5. Min: Minimum analog output value allowed regardless of input
The analog output source can be based on either of the input channel rate, total, or grand totals (Ch-A,
Ch-B), the math channel (Ch-C), maximum stored value of either input channel (Hi-A, Hi-B), minimum
stored value of either input channel (Lo-A, Lo-B), maximum or minimum of A and B (Hi-AB, Lo-AB), relay
set points, or the Modbus input.
To base an analog output on the rate, total, or grand total of channels A or B, select the channel in the
Analog Output Source menu. Then select the rate, total, or grand total as the source reference for the
output, and program the output scale.
Programmable Function Keys User Menu (user)
The User menu allows the user to assign the front panel function keys F1, F2, and F3, the digital input F4
(a digital input located on the signal input connector), and up to eight additional digital inputs to access
most of the menus or to activate certain functions immediately (e.g. reset max & min, hold relay states,
etc.). This allows the meter to be greatly customized for use in specialized applications.
Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter
(i.e. alarms, relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital
outputs can be used to trigger external alarms or lights to indicate these specific events.

The meter accepts two input channels (A and B) of either pulses (e.g. ±40 mV to ± 8V), square wave (0-5
V, 0-12 V, or 0-24 V), open collector NPN, PNP, TTL, or switch contact signals and displays these signals
in engineering units from -99999 to 999999. (e.g. a 0-1000 Hz signal could be displayed as -50.000 to
50.000).
Digital inputs and quadrature inputs can be accepted for bi-directional flow on channel A and B. Quadrature
inputs can also be accepted, using channels A and B to calculate a single bi-directional flow.
A totalizer can be programmed to count the scaled engineering units, interpreting it as count per second,
minute, hour, or day. The scaled rate and total for each channel can be displayed on the top or bottom
displays.
A math function channel (C) is available to perform operations on channel A and B rates or totals, with
adder and factor constants, and display the results. Engineering units or tags may be displayed with these
three channels.
The dual-line display can be customized by the user. Typically, display line 1 is used to display the math
channel C, while line 2 is used to alternate between displaying input channels A and B rate or total.
Additionally, the meter can be set up to display any input or math channel on display line 1 and a unit or
tag on line 2. The relays and analog output can be programmed to operate based on any input rate or total,
or the math function channel.
Function Keys Operation
During operation, the programmable function keys operate according to the way they have been
programmed in the Advanced Features – User menu.
F4 Operation
A digital input, F4, is standard on the meter. This digital input is programmed identically to function keys
F1, F2, and F3. The input is triggered with a contact closure to COM, or with an active low signal. During
operation, F4 operates according to the way it has been programmed in the Advanced Features – User
menu.
