Trim 4 mA / trim 20 mA
This is for calibrating the 4 mA and 20 mA output current from the transmitter. The output
current is temporarily set to 4 mA and 20 mA. Measure the
actual output current
and then input
that mA value to re-calibrate. The output current resumes normal operation after exiting.
Note
The re-calibration procedure is automatically cancelled after 20 minutes of inactivity, and the
previous calibration is restored.
