2.5 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.
2.6 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.
2.7 Power Off Time
If there won’t be pressed any key and no interface communication takes place for the time of the power off
time setting (P.Off), the device will be switched off automatically to save battery power.
If P.oFF = oFF then the automatic switch off is deactivated.
2.8 Output
The output can be used as serial interface (for GRS3100 or GRS3105 interface adapters) or as analogue
output (0-1V).
2.8.1 Interface - Base Address ('Adr.')
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 device 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. See also chapter 4.
2.8.2 Analogue Output – Scaling with DAC.0 and DAC.1
Note: Analogue output can not be used during logger recordings
With the DAC.0 and DAC.1 values the output can be rapidly scaled to Your efforts.
Keep in mind not to connect low-resistive loads to the output, otherwise the output value will be wrong and
battery life is decreased. Loads above ca 10kOhm are uncritical.
If the display exceeds the value set by DAC.1, then the device will apply 1V to the output
If the display falls below the value set by DAC.0, then the device will apply 0V to the output
In case of an error (Err.1, Err.2, no sensor, etc.) the device will apply slightly above 1V to the output.

Attention!
The 3

contact has to be left floating!
Only stereo plugs are allowed!
2.9 Alarm
3 possible settings: Alarm off (AL.oFF), on with horn sound (AL.on), on without horn (AL.no.So).
Following conditions will display an alarm, when the function is activated (on or no.So):
-
Value is below lower (AL. Lo) or above upper alarm rail (AL.Hi).
-
Sensor error (Sens Erro)
-
Low battery (bAt)
-
Fe 7: System error (always with sound)
In case of an alarm, and when polling the interface the prio-flag is set in the returned interface message.
2.10 Real Time Clock
The real time clock is used for the logger function: Recorded values are also containing the point of time,
when they were measured. Please check the settings when necessary.
If the battery was replaced the referring menu ‚CLOC‘ will automatically be started.
