4.10.2 ZERO – Δ offset
ZERO – Δ offset sets the differential value for a differential pressure measurement to zero.
Carry out the differential pressure calibration at the operating pressure; the calibration is only valid for this pressure. Connect
both sensors to the same port (using a T-adapter). The calibration sets the tolerance of the sensors in relation to each other to
zero. The calibration is carried out for safety reasons only when the calibrating values are less than 5% of full scale value of the
sensors. Otherwise, the display shows OFL.
The offset is saved until the instrument is turned off.
