2 Configuration
To change device settings, press Menu (key 4) for 2 seconds. This will call the configuration menu.
Pressing key Menu jumps between the parameters.
The parameters can be changed with 5 (key 2) or 6 (key 5).
Quit (key 6) finishes the configuration and returns to standard measuring operation.
2.1 Unit: Choice Of The Display Unit
Choose the desired display unit, the referring unit is displayed by means of a functional arrow in
the display. The selection is permanently stored in the device, therefore after power on the unit
will instantly reappear. The choice depends on the used sensor.
The unit [m] =mH
2
O is just supported by devices with [m] printed below the display!
2.2 P.oFF: Auto Power Off Time
The device will be automatically switched off if no key is pressed/no interface communication
takes place for the time of the power off time.
The power off time can be set to values between 1 and 120 min. It can be completely deacti-
vated by setting the parameter to ‚P.oFF = oFF“.
2.3 Adr: Base Address of Interface
Up to 10 devices of the GMH3xxx- handheld-family can be connected to a serial interface at
once (depending on interface converter, e.g. GRS3105: 5 devices). To get access to each de-
vice the base addresses of the devices have to be different. For example choose 01 for the first,
11 for the second device and so on.
2.4 OFFS: Adjusting Sensor Zero Displacement
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.
2.5 SCAL: Adjusting Sensor Scale
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.
