15.6 Calibrate the pump for 4-20mA control
This feature is only available in the Universal+ model.
The pump must be stopped before attempting to calibrate the 4-20mA values.

not be able to set the signal input value and progress to the next step in the process.
Select MODE.
Using the +/- keys scroll to Analog 4-20mA and press CALIBRATE 4-20mA.
Choose whether to enter the current values manually via the keypad, or whether to
apply the current signals electrically to the analogue input.
Setting a high signal
Send the high signal input to the pump, or enter the current value using the +/-
keys.
