FREE MeterView Pro
Programming Software
The meter can be powered from the Micro USB connection.
When using the Micro USB connection, DO NOT apply AC or DC
power to the meter.
The easiest and quickest way to program your PROVU
meter is to use the FREE MeterView Pro
programming software. This software is loaded into
the meter and connects and installs directly to your
PC with a USB cable. We recommend that the first
thing you do after taking the meter out of the box is
connect the PROVU to your PC with the provided USB
cable – do not use a different cable. DO NOT apply
AC or DC power to the meter while your PC is
connected to the meter as it will disrupt the USB
connection. You don’t even have to apply an input
signal.
MeterView Pro programming software is intuitive, and
most customers can get their meter programmed as
they like without even looking in the manual.
Registered Trademarks
All trademarks mentioned in this document are
the property of their respective owners.
In addition to programming, the software may be used
for:
•Monitoring
•Datalogging using your PC
•Generating and saving programming files for
later use
Once your meter is programmed the way you want it,
you can wire it up for your application per the
instructions in this manual and install it. If you find that
you need to make adjustments to the programming
after the meter is installed, you can use the front
panel buttons and the instructions in this manual to do
so.
The PROVU PD6300 is a multipurpose, easy to use
pulse input flow rate/totalizer tachometer ideal for flow
rate, speed, total, and 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 pulse (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. Three of the front panel buttons can
be custom-programmed for specific operation.
The basic model includes an isolated power supply
with field selectable power of 5, 10, or 24 VDC that
can be used to power the flowmeter, speed sensor or
other devices. An additional isolated 24 VDC power
supply is included with the 4-20 mA output option. A
digital input is standard.
A fully loaded PD6300 pulse rate/totalizer tachometer
has the following: four SPDT relays, 4-20 mA output,
a power supply for the flowmeter / speed sensor and
one for the 4-20 mA output. The PD6300 capabilities
may be enhanced by adding the following external
expansion modules: four SPST relays (creating an
eight-relay rate/totalizer), two digital I/O modules with
four inputs and four outputs each, and RS-232,
RS-485, and USB communication adapters.

Communications
Serial communications connection is made to an
RJ45 connector labeled M-LINK. For interfacing to the
PROVU, use the PDA1232 for RS-232 or the PDA1485
for RS-485. The same port is used for interfacing with
all expansion modules (e.g. external relays, digital
I/O).
Relay Connections
Relay connections are made to two six-terminal
connectors labeled RELAY1 – RELAY4. Each relay’s
C terminal is common only to the normally open (NO)
and normally closed (NC) contacts of the
corresponding relay. The relays’ C terminals should
not be confused with the COM (common) terminal of
the INPUT SIGNAL connector.
The use of snubbers to suppress electrical noise is
strongly recommended when switching inductive
loads to prevent disrupting the microprocessor’s
operation. The snubbers 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:
Figure 19: AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 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.
Figure 20: Low Voltage DC Loads Protection
RC Networks (Snubbers)
Available from Precision Digital
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 should be connected with a normally
open contact across F4 and COM, or with an active
low signal applied to F4. It can be used to reset the
total, for remote operation of front-panel buttons, to
acknowledge/reset relays, or to reset max/min values.

are identical and interchangeable; they are used to
connect additional modules to the system.
Note: The jumper located between the RJ45
connectors of the PDA1044 must be removed
on the second digital I/O module in order for the
system to recognize it as module #2.
•DO NOT connect or disconnect the expansion
modules with the power on! More detailed
instructions are provided with each optional
expansion module.

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 activate the interlock relay. This
feature is enabled by configuring the relay, and the
corresponding digital input(s), see Setting Up the Interlock Relay (Force On) Feature on page 32.
In the example below, an Interlock Contact switch is
connected to a digital input, which will be used to
force on (energize) the Interlock Relay. The Interlock
Relay and the Control Relay are connected in series
with the load.
•When the Interlock Contact is closed (safe), the
Interlock Relay energizes, allowing power to flow
to the Control Relay; the corresponding front
panel LED is on.
•When the Interlock Contact is open, the
corresponding front panel LED flashes (locked
out), the Interlock Relay is de-energized,
preventing power from flowing to the Control
Relay and the load.
The meter may either be scaled (SCALE)
without applying an input, calibrated (Cal) by
applying an input, or you may use the K-Factor
menu to match the rate/totalizer with a
flowmeter’s k-factor (pulse/unit of measure).
The meter comes factory calibrated to NIST
standards, so for initial setup, it is
recommended to use the K-Factor method or
(SCALE) function.
Overview
There is one switch, located to the right of the input
connector, which must be configured according to the
input level and type. Jumper J4 located inside the
meter, behind the input signal connector, is used to
select the excitation voltage (24 V*, 10 V or 5 V)
which is supplied to the P+ and P- wiring terminals.
Setup and programming is done using MeterView Pro
or through the front panel buttons.
After power and input signal connections have been
completed and verified, apply power to the meter.

Setting the Decimal Point (dEc pt)
The decimal point may be set with up to five decimal
places or with no decimal point at all. The rate, total,
and grand total decimal points are independent.
The decimal point selection should be made prior to
scaling, calibrating or programming the meter.
Pressing the right arrow moves the decimal point one
place to the right until no decimal point is displayed,
then it moves to the leftmost position.
Pressing the up arrow moves the decimal point to the
left.
Programming the Rate/Totalizer
(prog)
The meter may either be scaled (SCALE) without
applying an input, calibrated (Cal) by applying an
input, or you may use the K-Factor menu to match the
rate/totalizer with a flowmeter’s k-factor (pulse/unit of
measure). The meter comes factory calibrated to
NIST standards, so for initial setup, it is
recommended to use the (SCALE) function.
The Program menu contains the following menus:
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. Total reset mode for total & grand total
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. 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
prior to scaling and calibration of the meter. See
Multi-Point Linearization (Linear) menu on page 36
for details.
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 programmed in the Advanced Features menu. See Advanced Features Menu on
page 34.
The meter may be calibrated using the K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor
(Factor) 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.
Multi-Point Calibration & Scaling
The meter is set up at the factory for 2-point linear
calibration. The number of points for multi-point
calibration/scaling is set up in the AdvancedFeatures
menu. Up to 32 linearization points may be selected.
See Multi-Point Linearization (Linear) menu on page
36 for details.
Scaling the Meter (SCALE)
The pulse inputs can be scaled to display the process
variable in engineering units.
A signal source is not needed to scale the meter;
simply program the inputs and corresponding display
values.
For instructions on how to program numeric values
see Setting Numeric Values on page 21.
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:
InP 1
0.0
DiS 1
0.000
InP 2
1000.0
DiS 2
0.220
Set the time base to minutes (see Time Base, Total Conversion Factor & Total Reset on page 24) 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, 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*.
*Not relevant when scaling the meter.
For instructions on how to program numeric values
see Setting Numeric Values on page 21.
Minimum Input Span
The minimum allowed input span is 0.10 Hz, which is the
minimum difference between input 1 and input 2 signals
required to complete the calibration or scaling of the
meter.
Time Base, Total Conversion Factor
& Total Reset
The time base, total conversion factor, and total reset
menus are located in the Program menu.
The total and grand total have their own independent
settings. This means that one can be displaying the
value in gallons while the other displays in million
gallons, liters, m3, etc.
The time base is the amount of time over which the
rate parameter should accrue. For example, if the rate
was ten and the time base was in minutes, then the
total would increase by ten every one minute.
Total & Grand Total Conversion
Factor
The total & grand total conversion factor is the
amount by which the rate is multiplied before it is
added to the total or grand total. For Example, if the
rate was ten per second and the total conversion
factor was 100, the total would increase by 1000
every second. This is useful, for instance, if you want
to show rate in gallons and total in thousands of
gallons.
Total & Grand Total Reset
The totals can be programmed for automatic or
manual reset. In the automatic reset mode, a
programmable time delay is available to reset the total
or grand total after the assigned preset is reached.
The totals can also be reset via the front panel button,
via a switch across the on-board F4 terminal, the
PDA1044 digital I/O expansion module, or via a
Modbus command.
Non-Resettable Totalizer
The total and grand total can be password-protected
to prevent unauthorized resets. The grand total can
be programmed as a non-resettable total, see Total Reset Password & Non-Resettable Total on page 33
for details.
Calibrating the Meter with External
Source (Cal)
To scale the meter without a signal source, refer to
K-Factor Calibration on page 23 or Scaling the
Meter on page 24.
The meter can be calibrated to display the process
variable 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.
Note: The display values (DiS 1 and DiS 2) need to
be in units of measure per second.
Setting the Display Parameter &
Intensity (dsplay)
Display line 1 (line 1) can be programmed to
display:
1. Rate value
2. Total or grand total
3. Relay set points
4. Max & min values

After setting up the input and the display, press the
Menu button to exit programming and skip the rest of
the setup menu. Press the Menu button again and the
Up arrow to reach the Program menu and complete
the scaling or calibration of the meter.
Display Flow Rate, Total or Grand
Total
Line 1 can be programmed to display flow rate, total,
or grand total, and line 2 can be programmed to
display flow rate, total, grand total, engineering units,
custom legends, or be turned off. Both lines can also
display relay set points, or max and min values.
Display Toggling Between Reading
& Units
The PD6300 can be programmed so that line 1 and
line 2 toggle between the reading and their
engineering units. For instance, line 1 displays flow
rate, line 2 displays total, and the display toggles to
show their units.
Display Intensity (d-Inty)
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 is 6.
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.
Relay and Alarm Operation
Diagrams
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.
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.
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-nmAn)” reset mode is
selected, the LED follows the reset point and
not the relay state when the relay is
acknowledged.
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 flow alarms and basic batch control. There
are four basic ways the relays can be used:
1. High or Low Alarms with Latching or NonLatching Relays
2. Simple On/Off Control with 100% Adjustable
Deadband
3. Sampling (Based on Time)
4. Alternation Control for up to 8 Relays
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:

Alarm 8
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 visual-only 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 respond 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):
Latching and Non-Latching Relay
Operation
The relays can be set up for latching (manual reset)
or non-latching (automatic reset) operation.
Relay terminology for following tables
Terminology
Relay Condition
On
Alarm (Tripped)
Off
Normal (Reset)
Ack
Acknowledged
The On and Off terminology does not refer to the
status of the relay’s coil, which depends on the failsafe mode selected.
•In latching relay mode, if Fail-Safe is off, latched
relays will reset (unlatch) when power is cycled.
In this application, the meter is set up for automatic
reset (non-latching relay). Acknowledging the alarm
while it is still present has no effect on either the LED
or the relay. When the alarm finally goes away, the
relay automatically resets and the LED also goes off.
Non-Latching Relay with Manual
Reset (A-nman)
In this application, the meter is set up for automatic
and manual reset at any time (non-latching relay).
The LED and the relay automatically reset when the
meter returns to the normal condition.
In addition, the relay can be manually reset while the
alarm condition still exists, but the LED will stay on
until the meter returns to the normal condition.
Latching Relay (LatcH)
In this application, the meter is set up for manual
reset at any time. Acknowledging the alarm even if
the alarm condition is still present resets the relay and
turns off the LED.
Latching Relay with Clear (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.
Acknowledging Relays
There are three ways to acknowledge relays
programmed for manual reset:
1. Via the programmable front panel function keys
F1-F3 (Example: F3 assigned to ACK).
2. Remotely via a normally open pushbutton wired
to the F4 terminal at the rear of the instrument.
3. One of the digital inputs and the +5 V terminals
on the digital I/O expansion module.
When the ACK button or the assigned digital input is
closed, all relays programmed for manual reset are
acknowledged.
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.
Interlock Relay Operation Example
Relays 1 & 2 are configured to energize (their front
panel LEDs are steady on) when SW1 & SW2
switches (above) are closed. If the contacts to these
digital inputs are opened, the corresponding front
panel LEDs flash indicating this condition. The
processes being controlled by the interlock relay will
stop, and will re-start only after the interlock relay is
re-activated by the digital inputs (switches).
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 activate the relay.
Scaling the 4-20 mA Analog
Output (Aout)
The 4-20 mA analog output can be scaled to provide
a 4-20 mA signal for any display range selected.
No equipment is needed to scale the analog output;
simply program the display values to the
corresponding mA output signal.
The Analog Output menu is used to program the 4-20
mA output based on display values.
For instructions on how to program numeric values
see Setting Numeric Values on page 21.
Reset Menu (reset)
The Reset menu is used to reset the totals, maximum
or minimum reading (peak or valley) reached by the
process; both may be reset at the same time by
selecting “reset high & low” (rst HL).
Manual Control Menu (Contrl)
The Manual Control menu is used to control the
4-20 mA analog output 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 the
analog output for automatic operation.
The Password menu is used for programming three
levels of security to prevent unauthorized changes to
the programmed parameter settings 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
Enter the Password menu and program a six-digit
password.
For instructions on how to program numeric values
see Setting Numeric Values on page 21.
Total Reset Password & NonResettable Total
The total and the grand total can be passwordprotected to prevent unauthorized total resets.
The grand total can be programmed as a nonresettable total by entering the password “050873”.
•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 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.
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).
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.

*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.
Contact De-Bounce Filter (FiLter)
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.
The filter function (Filter) is the second option in the
Advanced Features menu. There are two settings,
Hi SPd (high speed) and Lo SPd (low speed), press
ENTER when Lo SPd is displayed to enable the filter
function. Program the filter value, so that there are no
extra counts when a contact closure is completed.

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.
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 on-board 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 6 for details.
•DO NOT connect any equipment other than
Precision Digital’s expansion modules, cables, or
meters to the RJ45 M LINK connector. Otherwise
damage will occur to the equipment and the
meter.
Select Menu (SElEct)
The Select menu is used to select the input signal
conditioner applied to the input (linear), low-flow
cutoff, and analog output programming. The multipoint linearization is part of the linear function
selection.
Input Signal Conditioning (Functn)
The Function menu is used to select the input signal
conditioner applied to the input: linear, where the
multi-point linearization is part of the linear function
selection.
Meters are set up at the factory for linear function with
2-point linearization. The linear function provides a
display that is linear with respect to the input signal.
When using more than one meter in a multi-drop
mode, each meter must be provided with its own
unique address. The meter address (Slave ID) may
be programmed between 1 and 247. The transmit
delay may be set between 0 and 199 ms. The parity
can be set to even, odd, or none with 1 or 2 stop
bits.
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 under the linear function. The multi-point
linearization can be used to linearize the display for
non-linear signals.
Low-Flow Cutoff (CutofF)
The low-flow cutoff feature allows the meter to be
programmed so that the often-unsteady output from a
differential pressure flowmeter, at low flow rates,
always displays zero on the meter.
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.
The Analog Output Programming menu is used to
program the behavior of the 4-20 mA output. The
following parameters and functions are programmed
in this menu:
1. Source: Source for generating the 4-20 mA
output (e.g. PV)
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
6. Calibrate: Calibrate the internal 4-20 mA source
reference used to scale the 4-20 mA output
Analog Output Source
The source for generating the 4-20 mA output may be
assigned to the rate/process variable, total, grand
total, maximum or minimum value reached by the
rate/process, one of the set points, or the Modbus PV
input.
Analog Output Calibration
To perform the analog output calibration, it’s
recommended to use a milliamp meter with a
resolution of at least 0.1 µA to measure the output
current. The values saved internally during this
procedure are used for scaling the 4-20 mA output in
the Setup menu.
Analog Output Calibration
Procedure
1. Wire the PD6300 4-20 mA output to a current
loop that includes a power supply (internal or
external 12 to 24 VDC), and the mA input on the
digital meter. See Figure 22: 4-20 mA Output Connections on page 16 for details.
2. Turn on all devices. Allow for a 15 to 30 minute
warm-up.
3. Go to the Advanced Features menu, and
navigate to the Analog Output Programming
(AoutPr)/Calibration (Calib) menu and press
Enter.
4. The display will show 4 nmA. The PD6300 mA
output should now be close to 4 mA. Press Enter
and the display will show 04.000. Enter the actual
value read by the digital mA meter and press
Enter.
5. The display will show 20 nmA. The PD6300 mA
output should now be close to 20 mA. Press
Enter and the display will show 20.000. Enter the
actual value read by the digital mA meter and
press Enter.
6. The meter will now calculate the calibration
factors and store them.
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 input signal
connector), and up to eight additional digital inputs to
access most of the menus or to activate certain
functions immediately (e.g. reset total, reset grand
total, 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. reset total, reset grand total, alarms, relay
acknowledgement, reset or display max, min). The
digital outputs can be used to trigger external alarms
or lights to indicate these specific events.

sequence (similar as on power-up) and loads the
factory default settings.
Factory Defaults & User Settings
The following table shows the factory setting for most
of the programmable parameters on the meter.
This meter is a highly sophisticated instrument with an extensive list of features and capabilities. If the front panel
buttons are used to program the meter, it may be a difficult task to keep everything straight. That is why we strongly
recommend the use of the free MeterView Pro software for all programming activities. A cable is provided with the
meter for programming with MeterView Pro software.
If you have programmed the meter with the front panel buttons and it is not working as intended, try
re-programming the meter using MeterView Pro software.
