NOTE:
The meter uses plug-in type screw terminal connectors for most input
and output connections and an RJ-6 phone connector for the optional RS-232 or
RS-485 serial outputs.
Input Signal – Pins 1 to 6
See the
I-Series Input Modules Guide (Z87)
for connection
details of all input modules. On most single input signal condi-
tioners, usually Pin 1 is the signal high pin (Hi +) and Pin 3 is
the signal low pin (Lo –).
Function Pins – Pins 8 to 15
Pin 8 – Program Lock
. By connecting the PROGRAM LOCK pin
to the COMMON pin (pin 11 on the main PCB), the PROGRAM
LOCK pin allows the meter's programmed parameters to be
viewed but not changed.
Pin 9 – Hold Reading
. By connecting the HOLD READING pin
to the COMMON pin (pin 11), the HOLD READING pin allows the

There are input
modules for almost
any input signal.
Input and Output
pins vary for
different modules.
Smart Modules
incorporate their own
A / D converters and
communicate digitally
with the meter.

meter's display to be frozen. However, A/D conversions continue
and as soon as pin 9 is disconnected from pin 11 the updated
reading is instantly displayed.
Pin 10 – Display Test and Reset
. The DISPLAY TEST and
RESET pin provides a test of the meter's display and resets the
microprocessor when the DISPLAY TEST and RESET pin is con-
nected to the COMMON pin (pin 11).
Pin 11 – Common
. To activate the HOLD, TEST and RESET, or
LOCKOUT pins from the rear of the meter, the respective pins have
to be connected to the COMMON pin.
Pins 14/15 – AC/DC Power Input
. These are the pins that supply
power to the meter. See Power Supply for details of the standard
and optional low voltage power supply.
