POS. INPUT VALUE (563)
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known. To correct the pressure difference, you need a reference
measurement value (e.g. from a reference device).
Example:
– MEASURED VALUE = 0.5 mbar (0.0075 psi)
– For the POS. INPUT VALUE parameter, specify the desired set point for the
MEASURED VALUE, e.g. 2.0 mbar (0.03 psi).
(The following applies: MEASURED VALUE
new
= POS. INPUT VALUE)
– MEASURED VALUE (after entry for POS. INPUT VALUE) = 2.0 mbar (0.03 psi)
– The CALIB. OFFSET parameter displays the resulting pressure difference (offset) by
which the MEASURED VALUE was corrected. The following applies:
CALIB. OFFSET = MEASURED VALUE
old
– POS. INPUT VALUE,
here: CALIB. OFFSET = 0.5 mbar (0.0075 psi) – 2.0 mbar (0.03 psi)= – 1.5 mbar (-
0.0225 psi))
Factory setting:
0.0
CALIB. OFFSET (319)
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure is known. (A reference pressure is not present at the device.)
Example:
– MEASURED VALUE = 2.2 mbar (0.033 psi)
– Via the CALIB. OFFSET parameter, enter the value by which the MEASURED VALUE
should be corrected. To correct the MEASURED VALUE to 0.0 mbar, you must enter
the value 2.2 here.
(The following applies: MEASURED VALUE
new
= MEASURED VALUE
old
– CALIB.
OFFSET)
– MEASURED VALUE (after entry for calib. offset) = 0.0 mbar
Factory setting:
0.0
