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.
