Transmitter Built-in Fuses

The built-in fuses protect the instrument against overload or faulty manipulation.

The built-in fuse may only be replaced by our factory service department.

Detecting that a fuse has tripped: The reason for the output signal generated by the transmitter

being only weak could be that the fuse has tripped. To verify whether the fuse has tripped, please

proceed as follows:

• Disconnect the transmitter from all connected measurement circuits.

• Switch on the transmitter.

• Set transmission level I.

• Perform a single-pole connection of one test lead to socket 1.

• Switch on the receiver.Search for the signal at the cable and place the sensor head on the cable.

• Insert the open cable end into connection socket 2.

• If the fuse is not defective, the displayed value on the receiver screen doubles.

Calibration Interval

We suggest a calibration interval of one year. If the instrument is used very often or if it is used

under rough conditions we recommend shorter intervals.If the instrument is used few times only the

calibration interval can be extended on to 3 years.
