Sensor Excitation Voltage Selection (EX+, EX-)
All meters, including models equipped with the 12/24 VDC power
option, are shipped from the factory configured to provide 10 VDC
excitation for the sensor.
If the sensor requires 5 VDC excitation, the internal jumper J3 must
be configured accordingly.
To access the voltage selection jumper:
1. Remove all the wiring connectors.
2. Unscrew the back cover.
3. Slide out the back cover by about 1 ½ inches.
4. Configure the J3 jumper, located behind the input signal
connector, for the desired excitation voltage as shown.
Caution!
Do not use 24V to power a strain gauge bridge.
The 24 V jumper configuration should only be
used for mV input applications.

Connections
All connections are made to removable screw terminal connectors
located at the rear of the meter.
Caution!
Use copper wire with 60°C or 60/75°C insulation for all line
voltage connections. Observe all safety regulations.
Electrical wiring should be performed in accordance with all
applicable national, state, and local codes to prevent
damage to the meter and ensure personnel safety.
