™ PD6402 High Voltage & mV to Current Meter
Instruction Manual

Meter
Operation
The meter is capable of accepting two input channels
(A and V) of either current (0-150 mV AC/DC) or
voltage signals (0-300 VAC/DC) and displaying these
signals in engineering units from -99999 to 999999.
A power function channel (P) is available to perform the
power operation (P = IV) on channel A and V, 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 channel
V, while line 2 is used to alternate between displaying
input channels A and P.
Additionally, the meter can be set up to display any
channel on line 1 and a unit or tag on line 2. The relays
and analog output can be programmed to operate
based on any channel.

The table above shows the factory default settings for
F1, F2, and F3.
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 is has
been programmed in the
Advanced Features
– User
menu. See

Maximum/Minimum Readings
The max & min readings (peak & valley) reached by
the process can be displayed either continuously or
momentary:
1. Display briefly by assigning to the F1-F3
function keys or to the digital inputs in the
User
menu.
2. Display continuously by assigning either
display to max/min through the
Display
menu.
Any of the F1-F3 function keys (buttons) and the
digital inputs can be programmed to reset the max &
min readings. The meters are set at the factory to
display the max reading by pressing the Up arrow/F2
button and to use the Right arrow/F1 button to access
the
Reset
menu.
To display max and min channel A reading using
function key with factory defaults:
1. Press Up arrow/F2 button to display minimum
reading of channel A since the last reset/power-
up. The display will then display the maximum
reading of channel A since the last reset/power-
up.
2. Press the Up arrow/F2 button again to display the
minimum reading of channel A since the last
reset/power up.
3. To reset max/min press Right arrow/F1 button to
access the Reset menu. The max & min displays
are reset to actual values.
4. Press Menu to exit max/min display reading.
