Adjustmentandcommissioning
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.
