PD6400 PROVUHigh Voltage & Current Meter
www.predig.com
The PROVUPD6400 is a multipurpose, easy to use high
voltage and current input meter ideal for measuring direct
voltage and current or the output from voltage shunts and
current transformers. It has one 0-300 VAC or VDC voltage
input and one 0-5 AAC or ADC current input. The meter may
be used with a single voltage or current input, or to measure
both simultaneously. A math channel P calculates apparent
power as the product of the voltage and current inputs.
The PD6400 can display voltage, current, and apparent
power. The dual line display can show any two parameters
simultaneously, or alternate between any parameters as well
as their programmable units and tags.
A fully loaded PD6400 meter has the following: four SPDT
relays and a 4-20 mA output. The PD6400 capabilities may
be enhanced by adding the following external expansion
modules: four SPST relays; creating an eight-relay meter, two
digital I/O modules with four inputs and four outputs each,
serial communication adapters for use with MeterView Pro or
Modbus RTU, and a dual 4-20 mA expansion module; for a
total of three 4-20 mA analog outputs.
Precision Digital offers a line of split core AC Current
transformers that can be used with the PD6400 meter to
measure AC current up to 1000 AAC.

The  is prompting for the
value for Input 2 and displaying
the default value of 5.00 A. The
“5” in 5.00 is brighter than the rest
of the digits indicating that it is the
number that will be changed by
the Up and Right arrows.
The  is now prompting
for what the user wants Display
2 to be; that is the value that
corresponds to 5.00 A. In this
case Display 2 is currently set to
95.00.
MeterView Pro can be used to scale the voltage and the
current inputs on the  PD6400 meter.
Toggling Between Reading & Units with
Tag and Calculating Apparent Power
The  below is programmed so the upper line toggles
between the reading and units, and the lower line displays a tag.
A math channel P calculates apparent power as the product of
the voltage and current inputs shown in the bottom two images.
Bright & Optional Super-Bright Display
The standard ’s display is bright enough for most
applications, including moderate sun exposure. However,
for direct sunlight exposure the  is available with
super-bright LEDs that make it possible to read the 
even in direct sunlight. Both versions of the  have eight
levels of adjustable intensity.
Rounding Feature for Even Steadier Display
The rounding feature is used to give the user a steadier display
with fluctuating signals. It causes the display to round to the
nearest value according to the rounding value selected (1, 2,
5, 10, 20, 50, or 100). For example, with a rounding value of
10, and an input of 12346, the display would indicate 12350.

The PD6400 can display voltage, current, and apparent
power. The dual line display can show any two parameters
simultaneously, or alternate between any parameters as well
as their programmable units and tags.
The ’s dual-line display makes all the difference both
when programming the instrument and when using it in the
field. When programming the instrument, the dual line display
prompts for the needed information and also helps you keep
track of where you are in the setup process. When using the
instrument, the dual line display provides more information
such as displaying the input in two different scales like Volts
and Amps for measuring shunts and transformers. We call
this the Dual-Scale feature.
Programming Assistance
The ’s PD6400 dual-line display makes programming
the instrument much easier because the lower line prompts
for the needed information and also helps you keep track of
where you are in the setup process.

QUICK & EASY SCALE & PROGRAMMING METHODS
The  can be programmed either via the front panel push buttons or free, PC-based MeterView Pro software. MeterView
Pro is resident on the  and is accessed by a provided USB cable, so it is by far the easiest way to program the .
The  can be calibrated either by applying a known signal or scaled by entering a desired value with the front panel buttons
or MeterView Pro software. Most customers will use the scaling method because it is simpler and does not require a calibrated
signal source. Selecting the input to be current or voltage is done with the front panel buttons or MeterView Pro software. Once
programming is completed it can be locked with a password.
Free PC-Based MeterView Pro USB Programming Software & Cable
The  comes preloaded with free MeterView Pro
programming software that connects and installs directly to
your PC with a standard USB cable, also provided free with
each instrument. This eliminates the need to insert CDs, install
drivers, or download software from the internet. When you
connect your  to your PC, MeterView Pro is downloaded
to your PC, the software automatically selects the model you
are programming, and you’re ready to start programming
immediately. Further simplifying the programming process, the
 can be powered from the USB port, so no need to apply
external power while programming your meter. In addition to
programming, the software will also allow you to monitor, and
datalog a  using your PC. You can also generate and
save programming files for later use.

4-20 mA OUTPUT & RELAYS
4-20 mA Analog Output
The isolated analog output can be configured to represent
the process variable (PV), maximum (peak) value, minimum
(valley) value, the value for any of the eight relay set
points, or Modbus input. While the output is nominally
4-20 mA, the signal will accurately accommodate under- and
over-ranges from 1 to 23 mA.
The 4-20 mA output can be reversed scaled such that 4 mA
represents the high value and 20 mA represents the low value.
For instance, a 4-20 mA output signal could be generated as
the meter went from 100.0 to 0.0.
For applications where the input was linearized by the ,
the 4-20 mA output will represent that linearized value.
Connections
The  can provide 40 mA at 24 VDC to power the

Relays for Alarm & Control Applications
Adding relays to the  meter turns it into a sophisticated alarm device as well as a powerful, yet simple, alternative to a
more complicated PLC system for control applications. The  can be equipped with up to four 3 A Form C (SPDT) internal
relays and an additional four more 3 A Form A (SPST) external relays. Relays are highly user-configurable as the following
screen shot from MeterView Pro indicates:
Setting Set and Reset Points (HI / LO Alarms)
All relays are independent of each other and may be
programmed as high or low alarms with user desired set and
reset points. Setting a set point above a reset point results in
a high alarm and setting a set point below a reset point results
in a low alarm. Alarms have 0 – 100% deadband and set and
reset points may be set anywhere in the range of the meter.
Resetting the Relays (Action in MV Pro)
All relays are independent of each other and may be
programmed to reset (Action in MV Pro) in the following ways:
• Automatic: Alarm will reset automatically once the alarm
condition has cleared.
• Automatic/Manual: Alarm will reset automatically once
the alarm condition has cleared but can also be reset
using the F3 front panel button* at any time.
• Latching: Alarm must be reset manually and can be
done so at any time. Press the F3 front panel button* at
any time to clear the alarm.
• Latching with Reset after Cleared: Alarm must be
reset manually and can only be done so after the alarm
condition has cleared. Press the F3 front panel button*
after the alarm condition has cleared to reset the alarm.
* Or by connecting an external switch to F4 terminal or with an optional digital input.
󰀨
In many applications it is desirable to wait before turning off
or on a relay – such as waiting for a process to settle before
taking action. Each relay on the  can be programmed
with independent on and off time delays of 0 to 999.9 seconds
to achieve this.
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.
Signal Loss or Current Input Break Relay Operation
When the meter detects a break in the current input, the relay
will go to one of the following selected actions:
1.

3. Ignore (Processed as a low signal condition)
User Selectable Fail-Safe Operation
All relays are independent of each other and may be
programmed for user selectable fail-safe operation. With the
fail-safe feature activated, the relays will transfer to the alarm
state on power loss to the meter.
*Values are intended to show programming choices. They are not intended to represent an actual application.

Front Panel LEDs
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.
Manual Output Control
Take control of any output
with this feature. All relays
can be forced ON or OFF,
and the 4-20 mA output
signal can be set to any value
within its range. When the
relays and 4-20 mA output are controlled manually, an LED
labeled “M” is turned on and the associated Alarm LEDs (1-8)
flash every 10 seconds indicating that the meter is in manual
control mode.
Sampling Function (PV Triggered Timed Relay)
The sampling function allows the operator to set a relay as a
“sampling” relay. When the PV reaches that set point, it will
close that relay’s contacts for a preset period of time (0.1 to
5999.9 seconds).

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. Precision Digital offers the PDX6901:
Interlock Relay(s)
This function allows a process to use one or more very low
voltage input signals or simple switch contacts to control the
state of one or more internal “interlock” relays. A violation
(i.e. loss of input, open switch, or open circuit) forces one or
more N/O interlock relay contacts to open. One input can be
used in series with a number of interlock switches, or up to
eight inputs can be required to force-on one (or more) internal
interlock relays. Requires PDA1044 Digital I/O module or
use of on-board digital input F4. Please see ProVu Series
Safety Interlock Feature whitepaper on our website for more
information.

Precision Digital offers a line of split core AC current
transformers that convert the high AC current flowing through
a cable or wire to a 0-5 AAC output that can be displayed
on a PD6400. The PDA6420 works with a PD6400 because
it puts out a 4-20 mA signal. They are available in ranges
of 100, 200, 400, 600, and 1000 AAC. These nonintrusive
devices feature split core convenience for easy installation
and are a cost effective solution for monitoring load or proof
of operation. The PDA6420 current transformers are ideal for
monitoring current loads on pumps, driving fans and blowers,
and sensing the status of heating coils and lighting.

DIGITAL COMMUNICATIONS
Modbus®RTU Serial Communications
With the purchase of a serial communication adapter, PROVU
meters can communicate with any Modbus Master device
using the ever-popular Modbus communications protocol that
is included in every PROVU. In addition to the typical Modbus
capabilities of reading PVs and writing set points, below are
some examples of other things that can be done with the
meter’s Modbus communications:
• Send a 6-character message to lower display upon an event
• Convert a digital value to a 4-20 mA signal
• Remote user control (i.e. change set points, acknowledge
alarms)
• Input a Modbus digital PV (in place of analog input)
• Remote override of any, or all, relays and analog outputs
Remote MessageModbus PV Input
Serial Communication Devices
Precision Digital provides a variety of serial communication
devices to interface the  meter with other devices. For
more information visit predig.com/ProVuSerialDevices.
PDA1232 & PDA1485 Communication Modules
Serial communications on the PROVUmeter can be added
anytime with external PDA1232 (RS-232) or PDA1485 (RS-485)
communication adapters. Free Modbus protocol is included for
use with the PROVUserial communications modules.
FIELD EXPANSION MODULES
Add functionality to the PD6400 n the field with easy-to install
external expansion modules. External expansion modules are
available for RS-232 or RS-485 communications, digital I/O,
4 relays and dual 4-20 mA outputs. The menu items for these
modules do not appear until the module is connected, simplifying
the basic menu. Relay and digital I/O modules are shown below
with optional DIN rail mounting kit, P/N PDA1002.
PDA1044 I/O Expansion Module
Four digital inputs and four digital outputs are available per
expansion module. The PROVUmeter will accept two of these
modules. External digital inputs can function similarly to the
front panel function keys or on-board digital input F4. They
can be configured to trigger certain events (i.e. acknowledge/
reset alarms) or mimic front panel keys. The I/O module can
be used to configure the PROVUremotely, in essence giving
the user control of the four front panel push buttons.
Digital outputs can be used to remotely monitor PROVU’s
alarm relay output states, or the states of a variety of actions
and functions executed by the meter.

PHYSICAL FEATURES
The  is designed for ease-of-use in industrial
applications. Considerations include a NEMA 4X front panel,
wide operating temperature range, removable screw terminal
connectors, snap in place mounting brackets, forgiving panel
cutout requirement, and UL Listing for electrical safety. All of
these features are backed by a 3-year warranty.
Type 4X / NEMA 4X Front Panel
Not only does the ’s
front panel UL Type 4X
approval indicate it is
waterproof, but it also
indicates it is rugged. Part of
the UL Type 4X test is to drop
a 2 inch solid stainless steel
ball from 8 feet on top of the
meter’s faceplate.
Wide Operating Temperature Range
The  can operate from -40 to 65°C (-40 to 150°F)
meaning it can be installed in a wide variety of indoor and
outdoor industrial applications. And over this range, the
 will drift no more than 0.005% of calibrated span/°C
max from 0 to 65°C ambient and 0.01% of calibrated span/°C
max from -40 to 0°C ambient.
Removable Screw Terminal Connectors
Industrial applications require screw terminal connections
for easy field wiring and the  goes one step further in
convenience by making them removable also.
Easy Plug-in Removable
Terminal Connectors
Forgiving Panel Cutout Requirement
The ’s bezel has been oversized to allow for not
perfectly executed panel cutouts where NEMA 4X seal is not
required.

Secured-in-Place Rugged Mounting Brackets
If you’re installing the  outdoors in the hot or cold
weather, the last thing you want to do is fumble around with
mounting brackets that don’t stay in place. The ’s
mounting brackets can be easily secured into place and then
screwed down to the panel. These brackets are rugged so they
can be tightened to the panel to provide a solid NEMA 4X seal.

Remote Operation of Front Panel Buttons
The user can operate the front panel buttons from a remote
location by using digital inputs programmed in the following
manner:
Max / Min Display
Max/Min (or Peak/Valley) is standard on the  PD6400.
Either display can be configured to show either maximum or
minimum excursion since last reset. The displays can also
be configured to toggle between Max and Min values. Both
values can be simply reset from the front panel.
MeterView Pro Monitoring & Datalogging
Software
Not only does free MeterView Pro software greatly simplify
setup and programming of the , it can also be used to
monitor and datalog your process.
• Custom Tags: i.e. Power
• Custom Units: i.e. Amps, Volts
• Alarm Status Indicators
Datalog Report
Collected data logger information can be sent to a CSV file for
importing into a spreadsheet program. Below is an example of
one such file. Of course, once within the spreadsheet, much
can be done to customize the data.
Relay Control
Relays can be controlled from MeterView Pro for testing
purposes. This is commonly done to determine whether the
relays are functioning properly. In the Setup window, under
Relay and Digital Out Test you have the option of selecting
the relays you want in an ON state or OFF state and also
whether you want to leave the relays in manual control or to
return them to automatic operation.

Overview
Precision Digital offers a wide variety of NEMA 4 and
NEMA 4X enclosures that can be equipped with MOD-LH
Light / Horn and Reset Button. When MOD-LH is ordered, the
accompanying enclosure on the order comes with the holes
pre-drilled for the Light / Horn and the Reset Button and the
user performs the mounting and wiring. Meter and enclosure
are sold separately. The Light / Horn and the Reset Button
can also be ordered as separate items and the user performs
all hole-drilling, mounting and wiring as desired. The light
and horn can be controlled independently of each other via
separate relays on the  meter; and since the meter's
relays can be reset in a variety of ways, there are several
ways the Light / Horn option can operate. For instance, the
horn can be programmed to silence at any time via the Reset
Button or F3 front panel button on the , and light to
reset automatically when the alarm clears as the following
table illustrates:
Relay # Connected to Default Reset Mode
1Flashing Light(1) Auto reset
2Horn Silence with Reset Button at any time
3User Device As user desires
4User Device As user desires
1. Light can be wired to flash or stay steady on.
2. See page 10 for additional ways the relays can be programmed
 Meter in a PDA2301 Enclosure with MOD-LH Light / Horn and Reset Button.
