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.

plug wiring:
+Uout
Attention!
The 3
rd
contact has to be left floating!
Only stereo plugs are allowed!
2.9 Alarm
3 possible settings per channel: 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.
If the horn sound of one channel will be switched on/off (on or no.So), then this horn sound setting will
automatically be copied to the other activated channels.
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.
3 Operation Of Logger
The device supports two different logger functions:
„Func-Stor“: each time when „store“ (key 6) is pressed a measurement will be recorded.
„Func-CYCL“: measurements will automatically be recorded each interval, which was set in the logger
menu ‚CYCL‘ until the logger will be stopped or the logger memory is full. The recording is
started by pressing „Store“ 2 seconds.
The logger records 3 measurement results each time:
current or mean value (depending on logger setting, see below), min peak and max peak of sensor 1
current or mean value (depending on logger setting, see below), min peak and max peak of sensor 2
current or mean value (dep. on logger setting), min peak and max peak of sensor 1 - sensor 2
Min and max peak are the minimum resp. the maximum of the measured values since the last recording.
Using them allows f.e. analysis of fluctuating pressures. For the evaluation of the data the software
GSOFT3050 has to be used. The software also allows easy configuration and starting of the logger.
When the logger is activated (Func Stor or Func CYCL) the hold function is no more available, the key 6 is
solely used for the operation of the logger functions.
