Rear Panel Pinout Diagram
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 conditioners, usually Pin 1 is the signal high
pin (Hi +) and Pin 3 is the signal low pin (Lo –).
Function Pins – Pins 18 to 22
Pin 18 – 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 19 – Hold Reading
. By connecting the HOLD READING pin to the
COMMON pin (pin 11), the HOLD READING pin allows the 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 20 – 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 connected to the COMMON pin (pin 11).
Pin 21 – 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 24/25 – 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.
Chassis Ground Tab
. Only on versions with metal sheath casing.

WARNING
:
AC and DC input signals and power supply
voltages can be hazardous. Do Not connect live wires to screw
terminal plugs, and do not insert, remove or handle screw terminal
plugs with live wires connected.
