Martindale FD650 Digital FUse Finder kit expands the capabilities of the standard FD550 so that it can also be used on light fittings or other points in a circuit in addition to 13A sockets.

Its receiver has both fast manual mode and auto threshold mode set by a single sweep over the board. The auto mode sets the sensitivity to ignore weaker signals which can be caused by coupling between circuits ensuring easy detection in a wide range of installations. The receiver will work with multiple transmitters and can also be used as a non-contact voltage indicator.

This kit includes a twin lead set with crocodile clips (TL83), IEC mains lead (EX332) and a soft carry case.
