Performing zero calibration
We recommend performing a zero calibration after first start-up and after changes have
been made to the plant.
To set zero, the pressure in the measuring lines must be equal. To check zero, make sure that
the pressures in both measuring chambers are identical at atmospheric pressure, i.e. the sig-
nal at the terminals 31 and 32 must be 4 mA at a differential pressure of ∆p = 0 mbar (see
Fig. 7 on page 37).
At ∆p = 0 mbar, the 0.0 % reading must be displayed.
