Connect the transmitter to the line to be measured.
Then switch on the receiver and start tracing, see Fig.
a and b. The receiver signal sounding indicates that
the measured object belongs to the same electrical
circuit. The receiver is able to detect cables up
to a maximum depth of 5 cm. Various installation
conditions and metal shielding can drastically
influence the maximum measuring depth.
Tip 1: Set the receiver to maximum sensitivity and
hold the sensor head as close as possible to the cable
connection.
Switch on and
decrease sensitivity
4 Locating fuse circuits
!
– Measurement under voltage! It is essential that you follow the safety instructions.
– The cover of the fuse box may only be removed by a skilled electrician.
Connect the transmitter to the line to be measured.
Then turn on the receiver and start tracing. See Fig. c.
The detected fuse is located in the area where the
signal tone of the receiver sounds. Due to different
installation conditions (RCD automatic circuit breakers,
types of fuses etc.), in most cases it is not possible
to precisely locate the fuse but rather only to narrow
down the area where it is located.
Tip 2: Decrease the receiver sensitivity in steps in order
to closely narrow down the location of the fuse.
Tip 3: Rotate the receiver around its longitudinal axis
by 90° or modify its horizontal and vertical positions.
This will adjust the device to different automatic
circuit breakers, which have magnetic coils installed in
different positions. Re-adapt the sensitivity if necessary.
