nput position adjustment - the pressure difference betwen
zero (set value) and measured pressure must not be known
(
there is a reference pressure on the instrument).
Example:
l MEASURED VALUE = 2.2 mbar
l You correct the MEASURED VALUE via the parameter
POS. ZERO ADJUST
with the option "Confirm", i.e. you
assign the value 0 to the existing pressure
l MEASURED VALUE (after pos. zero adjust) = 0 mbar
l The current value is also corrected
l Default setting 0
