p-Adjustment
In case of a zero drift, the display can be set to zero with the 0-point potentiometer (below the
board). Adjustment should be carried out only when no differential pressure is present, i. e. if no
measuring hoses are connected. For a better accuracy of the adjustment, check the current output
0(4) to 20 mA at terminals 23+ and 24-.
Adjustment should be carried out at operational temperature as the sensor can present a
temperature drift of up to ± 1 mbar.
