3.6 Analog Mode Calibration Procedure
The scope of the following procedure is to calibrate analog output and input mA signal to let the
pump recognize 4 mA and 20 mA. When the measured value by PRO KIT is quite different from
the input value (at least 0,3 mA difference), this procedure will help the accuracy of 4-20 mA
signal.
Disable Analog Output
The first operation to be accomplished is to disable analog mA output:
1) Go to the menu "settings→Analog output"
2) Set the analog output to "NO" clicking on it
