Martindale's FD650 consists of a fuse finder and receiver for sending a signal directly through mains sockets, light fittings and circuits in order to locate fuse presence.

Featuring adjustable sensitivity, its easy to program the finder to send the necessary signal to locate a fuse on a circuit (particularly when used on breakers with multiple fuse options). The fuse finder also includes a full non-contact voltage detector built into the end of the tester, ensuring user safety at all times when testing.

This fuse finder uses transmission pulse width of approximately 1.7μS (width), with transmission pulse amplitude of 20A max and frequency range of 50-60Hz. A 6 segment bargraph displays shows how signal strength is slowly stepping up, making identification of fuses as quick as possible.

The FD650 is actually a bundle professional pack of equipment and comes with a set of test leads for using the finder on lighting circuits and a mains adaptor for using it on 13A sockets.
