INTRODUCTION
The PROVU® PD6400 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 wit h 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 display any two parameters simultaneously, or can alternate between any
parameters as well as their programmable units and tags.
A fully loaded PD6400 meter has the following: four SPDT relays, 4-20 mA output, and a
24 VDC power supply. 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 a nalog outpu t s.

SAFETY INFORMATION
Read complete instructions
prior to installation and
operation of the meter.
Risk of electric shock or
personal injury.
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 setting up a 12/24 VDC powered meter to
operate from 12 VDC, see page 17.
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.
