SEARCH FOR FUSES

The transmitter is connected to the phase and neutral conductors of the circuit of
which the protection fuse is to be located.
The use of the connection accessories (for mains outlet, for sockets) is strongly
recommended.
Preconditions:

Trip all the circuit-breakers of the distribution box;

Connect the transmitter as shown in figure 19.
Remarks:

The identification and location of the fuses are strongly influenced by the
condition of the wiring of the distribution frame. In order to locate fuses as
precisely as possible, it may be necessary to open or remove the cover of the
distribution frame, in order to isolate the fuse supply wire.

During the search process, the fuse delivering the most powerful and most
stable signals is the one sought. Because of the coupling of the connections,
the detector can detect signals from other fuses, but their power is relatively
low.

During the detection, it is best to place the probe of the detector on the input
of the fuse holder in order to obtain the best detection result.

Adjust the power transmitted by the transmitter according to the various radii
of detection.

Select manual mode on the receiver and a suitable receive sensitivity to
locate the circuit precisely.
