(*) If the logger memory contains data already, the menus/parameters marked with (*) can not
be invoked! If these should be altered the logger has to be stopped and the memory has to
be cleared before!
Hint: Restoring of ex-works settings
The settings will be set to the settings ex works, if keys ‘Set‘ and ‘Store‘ are pressed simultaneously
for more than 2 seconds.
7 Remarks To Special Features
7.1 Display Resolution
Standard setting: 'Auto', i.e. the device automatically switches over to the optimum resolution between .01°
and 0.01°.
If temperatures to be measured are near the switching threshold, a fixed resolution may be better, e.g. for
easy manual recording. In such a case please set the optimum resolution to the desired value.
7.2 Average filter („t.AuG“)
The filter forms the arithmetic floating average over the entered time. The displayed value will be
correspondingly slower in this case.
7.3 Alarm („AL.“)
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 message.
