Manual offset adjustment:
Precondition: DIP switch 6 is in ON position.
Switch must remain in ON position. If switched to OFF, "auto offset" is activated.
See also "Automatic offset setting".
At this setting OFFSET ΔP can be aligned at the potentiometer.
The range for adjustment is ca. ± 10 % of the pressure range.
A different reference point other than the zero point can be used here.

1140 / PREMASREG
PREMASGARD
(Range: 0...+ xx Pa)
After successful zero point calibration, the output voltage
is 0 V at 0 Pa pressure difference (with the offset knob
in central position)!
Output voltage 0...10 V
for pressure difference from 0 Pa to final value

(Range: - xx ...+ xx Pa)
After successful zero point calibration, the output voltage
is 5 V at 0 Pa pressure difference (with the offset knob in
central position)!
