4.5.2 Analogue Output – Scaling with DAC.0 and DAC.1
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
rd
contact has to be left floating!
Only stereo plugs are allowed!
4.6 Alarm
There are three possible settings: Alarm off (AL. oFF), on with horn sound (AL. on), on without horn sound (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
-
Low battery (bAt)
-
Err.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.
4.7 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.
