7.4.2 Perform an analog loop test

During a loop test, the transmitter outputs a fixed value (4 mA, 20 mA, or user-selected

value).

The loop test command verifies the output of the transmitter, the integrity of the loop,

and the operations of any recorders or similar devices installed in the loop. A loop test can

also be used to determine the need for an analog output calibration.

Procedure

Select Service Tools → Simulate.

2. Under Analog Out, select Loop test, and then follow the on-screen instructions.

3. Measure the loop current.

Postrequisites

Select Stop or Cancel to exit loop test (Abort on handheld communicator).
