17.30 Trim mA Output
Trimming an mA Output calibrates the transmitter's mA Output to the receiving device. If the current trim
value is inaccurate, the transmitter will under-compensate or over-compensate the output.

17.30.1 Trim an mA Output using the display
Trimming the mA Output establishes a common measurement range between the transmitter and the device
that receives the mA Output.
Prerequisites
Ensure that the mA Output is wired to the receiving device that will be used in production.
Procedure
1. Choose Menu > Service Tools > mA Output Trim and select the output to trim.
2. Follow the instructions in the guided method.
Important
If you are using a HART/Bell 202 connection, the HART signal over the primary mA Output may affect
the mA reading. Disconnect the wiring between ProLink III and the transmitter terminals when reading
the primary mA Output at the receiving device. Reconnect to continue the trim.
3. Check the trim results. If any trim result is less than −20 microamps or greater than +20 microamps,
contact customer service.
