f. Read the mA current at the receiving device and compare it to the transmitter
output.
The readings do not need to match exactly. If the values are slightly different,
you can correct the discrepancy by trimming the output.
g. Press OK.
h. Choose End.
2. Test the frequency output(s).
Note
If the Weights & Measures application is enabled on the transmitter, it is not possible to
perform a loop test of the frequency output, even when the transmitter is unsecured.
a. Press Service Tools > Simulate > Simulate Outputs > Frequency Output Test, and choose
the frequency output level.
b. Read the frequency signal at the receiving device and compare it to the
transmitter output.
c. Choose End.
3. Test the discrete output(s).
a. Choose Off.
b. Verify the signal at the receiving device.
c. Press OK.
d. Choose On.
e. Verify the signal at the receiving device.
f. Press OK.
g. Choose End.
Postrequisites
• If the mA output reading at the receiving device was slightly inaccurate, you can
correct this discrepancy by trimming the output.
• If the mA output reading at the receiving device was significantly inaccurate, 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 reading is reversed, check the setting of Discrete Output Polarity.

Trim mA outputs
Trimming an mA output calibrates the transmitter's mA output to the receiving device. If
the current trim values are inaccurate, the transmitter will under-compensate or over-
compensate the output.
