WARNING!
The Loop Diagnostics application is a generic tool that, if misused, can interfere with an
operating HART loop or may damage the ammeter in the Device Communicator Plus
communication module. Do not provide Trex power or current on a loop that is in operation.
Do not provide external power directly across the Trex mA terminals because this may damage
the ammeter.

1.
To open the Loop Diagnostics application, tap the

icon on the Trex
Home screen.
2.
To close the Loop Diagnostics application, tap

.
If you enabled the Trex unit to power a device, the Trex unit stops providing power
when you close the Loop Diagnostics. If the Trex unit was powering a positioner, the
application prompts you to select a current value for the positioner before the
application closes. This allows you to move the positioner to a safe position. After
the selected current value is reached, the Trex unit stops providing power.
