User Guide
Avoid using the ammeter in cold or very hot temperatures. Extreme temperatures
can affect the accuracy of the measurements.
Connect the mA terminals on the Trex unit to the "low-side" of the device. See the
example below.
"Low-side" ammeter connection

Ensure sufficient grounding. Ensure the personnel, working surfaces, and packaging are
sufficiently grounded when handling electrostatically sensitive parts.
Avoid touching the pins on the connectors or components. Discharged energy can affect
the modules.
Handle the module with care. It is possible to bend the pins on the module's connector.
Turn off the Trex unit.
Place the Trex unit face down on a level, secure surface.
Place the communication module into the top of the Trex unit, and carefully align
the communication module with the connector on the Trex unit.
Gently press the communication module until it is seated properly with the Trex
unit.
Tighten the four screws using a screwdriver. Do not over tighten the screws. Use
0.5Nm maximum torque load.
