Adjustment and commissioning

Connect the analogue input AI1 or AI2 to the current or voltage analogue output of an external instrument (for

instance, the 4-20 mA output of a pressure measuring device type 8311).

The analogue input signal is adjusted (slope and offset) and the multiCELL

displays the input calibrated value.

→ Generate a 4 mA current on the 4-20 mA output of the instrument con-

nected to the analogue input.

→ Enter 4 mA.

→ Wait for the measurement to stabilize.
