Differential Value Alignment (In1=In2) - WEBTEC HPM Manual

5.6 Differential value alignment (IN1=IN2)
Carry out differential value alignments at below operating pres-
sure. Connect two pressure sensors to the same connection
(T-adapter). ∆p-calibration sets the tolerance of the sensors in
relation to one another to zero.
This setting remains stored; it is valid only for the respective op-
erating pressure.
