9 Input Adjustment
9.1 Zero Displacement Sensor ('OFFS')
A zero displacement can be carried out for the measured value:
value displayed = value measured - offset
Standard setting: 'off' = 0.0°, i.e. no zero displacement will be carried out. Together with the scale correction
(see below) this factor is mainly used to compensate for sensor deviations. Input is in the display unit.
9.2 Scale Correction Sensor ('SCAL')
The scale of the measuring can be influenced by this setting (factor is in %):
displayed value = measured value * (1+Scal/100)
Standard setting: 'off' =0.000, i.e. value is not corrected. Together with the zero displacement (see above)
this factor is mainly used to compensate for sensor deviations.
9.3 Calibration Services
Calibration certificates – DKD-certificates – other certificates:
If device should be certificated for its accuracy, it is the best solution to return it to the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get results of highest accuracy!
10 Pressure Connection
2 (or 1) universal pressure connector for 6 x 1 mm (4 mm tube inner diameter) or 8 x 1 mm (6 mm tube inner
diameter ) plastic tubes.
10.1 Device type with absolute pressure (GMH 3161-12)
Connect plastic tube to pressure port
10.2 Device type with relative pressure
For measurements of overpressure (refer to summary):
Connect plastic tube to pressure port "+".
Port "-" will not be used!
For measurements of underpressure (refer to summary):
Plug the tube to pressure port "-". The measuring range covers then up to max. overpressure range
Note: All values are displayed now as positive values. No minus sign will be shown.
Example: it is possible to measure under pressure down to -25.00 mbar, the display shows then
the value 25.00 (no minus sign).
For measurements of pressure differences:
Connect both plastic tubes to pressure port "+" and "-"; make sure to apply higher pressure to port "+".
Measure ranges:

over- or under pressure
