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.
10.14.1

Trim mA output using ProLink III

Trimming the mA output establishes a common measurement range between the
transmitter and the device that receives the mA output.
Important
You must trim the output at both ends (4 mA and 20 mA to ensure that it is compensated accurately
across the entire output range.
Prerequisites
Ensure that the mA output is wired to the receiving device that will be used in production.
