Perform loop tests using the Field Communicator

Prerequisites
Before performing a loop test, configure the channels for the transmitter inputs and
outputs that will be used in your application.
Follow appropriate procedures to ensure that loop testing will not interfere with existing
measurement and control loops.
Configuration and Use Manual
c. Click Fix FO.
d. Read the frequency signal at the receiving device and compare it to the
transmitter output.
e. Click UnFix FO.
Test the Discrete Output(s).
a. Choose Device Tools > Diagnostics > Testing > Discrete Output Test.
b. If your transmitter is configured for two Discrete Outputs, determine which
Discrete Output you want to test.
c. Set Fix To: to ON.
d. Verify the signal at the receiving device.
e. Set Fix To: to OFF.
f. Verify the signal at the receiving device.
g. Click UnFix.
h. Repeat for the other Discrete Output, if applicable.
Test the Discrete Input.
a. Set the remote input device to ON.
b. Choose Device Tools > Diagnostics > Testing > Discrete Input Test.
c. Verify the signal at the transmitter.
d. Set the remote input device to OFF.
e. Verify the signal at the transmitter.
If the mA Output readings are within 20 microamps of the expected values, you can
correct this discrepancy by trimming the output.
If the discrepancy between the mA Output readings is greater than 20 microamps,
or if at any step the reading was faulty, verify the wiring between the transmitter
and the remote device, and try again.
If the Discrete Output readings are reversed, check the setting of Discrete Output
Polarity.
If the Discrete Input readings are reversed, check the setting of Discrete Input
Polarity.
