Pr. 900 "FM terminal calibration"
Using the parameter unit, you can calibrate the full scale of a meter connected to
the FM instrument connection terminal.
The terminal FM outputs a 1mADC current at the value set in Pr. 55 or 56. When
the full scale of the meter used must be calibrated, it can be adjusted using Pr.
900.
For the calibration procedure, refer to the instruction manual of the parameter
unit.
