Used or defective batteries or storage batteries may contain hazardous substances and
must be disposed according to the legal provisions of your country.
3.1.4.2 Power supply unit
For mains operation, the power supply unit must be used. If operated via the power supply unit,
batteries should be inserted to supply the internal time clock, otherwise, after approx. 1 minute, the
settings of the real-time clock will go lost as soon as supply from the mains is cut.
The power supply unit comes with two different adapter plug versions (Euro and US plug). If the
power supply unit comes with an adapter plug connected that does not match your socket, simply
change the adapter plug accordingly.
Simply remove the adapter from the power supply unit and fix the other one as required.
Note:
The adapter has not been designed for frequent change.
3.2 Sensors FH 4 and FH 10
3.2.1 General Remarks
In this new SIDSP (Sensor integrated digital signal processing) procedure, all necessary
measuring signals are created and completely processed in the sensor itself. Only the completely
processed digital readings are transferred to the base unit for display, statistical evaluation and
data storage. Unlike the commonly used analog procedures, the new SIDSP procedure excludes
any error influences on the measuring data during transfer over the probe cable. The result is a
measuring accuracy and constancy of readings that has been unmatched so far. The complete
sensor technique is integrated into a robust stainless-steel housing.
3.2.2 Sensor Models
Two sensor models are available:
-
FH 4 sensor to cover the 0 …4 mm range
-
FH 10 sensor to cover the 0…10 mm range.
Both sensors feature a wear-resistant sensor tip most suitable also for hard materials such as
glass, for instance.
