Fuse Finder Instructions
FD500 & FD600
The job of locating electrical circuits (AC circuits of 230V ± 10%) is now made
quick and easy. No more guessing or trial and error when it comes to locating the
correct circuit breaker or fuse supplying electrical power to a socket or lighting
fixture (FD600 only).
WARNING
Always check that the Fuse Finder units are operating properly before
proceeding.
These instructions contain both information and warnings that are
necessary for the safe operation and maintenance of the unit. It is
recommended that you read the instructions carefully and ensure that the
contents are fully understood. Failure to understand this leaflet and to
comply with the warnings and instructions contained herein can result in
serious injury or damage.
The units must only be used under the conditions and for the purposes for
which it has been constructed. Particular attention should be paid to the
safety instructions, the technical specifications and the use of the units in
dry surroundings.
The FD500 has a 13A plug-like transmitter unit. The FD600 is provided with two
alternative means of connecting the transmitter unit to the mains.
1. A 13A adaptor.
2. A two way fused lead set - TL83.
For tracing circuits with 13A sockets, use the 13A adaptor to connect the
transmitter unit to the socket.
For use at bare wires and light fittings, use the TL83 lead set to connect the circuit
red to live, black to neutral. Switch off the supply if possible or take appropriate
precautions while connecting to live unshielded contacts.
PREPARING TO USE THE FUSE FINDER
Battery Installation
1. Remove battery cover of receiver.
2. Connect 9V battery (not supplied) and insert into compartment.
3. Re-install battery cover.
Unit Test (Always carry out before use)
1. Plug the FD500/T transmitter into an electrical wall outlet or for the FD600 by using the
13A adaptor or the TL83 lead set and turn the power on.
2. Turn receiver on just until a click is heard and the LED lights. This is the maximum
sensitivity.
3. Place receiver near transmitter. If receiver is working and the wall outlet's power is on,
the receiver will produce a distinctive beep and the LED will flash.
USING THE FUSE FINDER
Locating the Fuse or Circuit Breaker controlling a wall socket.
1. Plug the FD500/T transmitter into an electrical wall outlet or for the FD600 by using the
13A adaptor or the TL83 lead set and turn the power on.
2. Check unit as in "Unit Test" section.
3. Go to fuse box (consumer unit) and place flat surface of receiver at a right angle to and
directly on the fuse or circuit breaker (Fig. 1).
4. Slowly move the receiver along the row or rows of fuses while continually lowering the
receiver's sensitivity by rotating the wheel away from the arrow until only one fuse causes
the receiver to beep.

The receiver must
be held at this
angle to best
receive the signal.
