7C-2 Locate fuses
!
– 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 sender to the phase conductor and the neutral conductor (N). Then turn on the receiver and
begin searching. Follow the signal in the sub-distributor. See image l. Adjust the receiver's sensitivity and
the sender's output power little by little until you have located the fuse.
The accuracy in locating fuses always depends on the various installation condition (RCD machines, types
of fuses etc.).
Recommended settings for the receiver: Manual search mode, minimum sensitivitiy, see chapter 5C.
Tip 12: When locating a fuse, pay attention to the numbers in the numerical display. The highest value will
appear when in the vicinity of the desired fuse.
Tip 13: 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.
Tipp 14: You will achieve the best results by measuring directly at the connections.
Tipp 15: These measurements may be taken without voltage as well. Some installation conditions produce
more accurate results than others.

to maintain full functionality.
– The acoustic signal may be deactivated in the receiver. See chapter 1.
