The Martindale FD650/R is a combined AC voltage detector and fuse finder receiver (when used in combination with the FD500/T or FD600/T transmitter). The Elite Professional Fuse Finder makes identifying poorly labelled fuses and breakers easy without the need to power down each circuit to identify the one you need to work on. The Elite receiver even includes a non contact voltage detector.

As a fuse finder the FD650/R can be operated with either manual or automatic setting of its sensitivity threshold to find the fuse or circuit breaker that produces the maximum signal. In manual mode the press of a push-button will set the sensitivity threshold to bring the detected signal to mid scale on the bar graph.

In automatic mode the FD650/R will automatically set the sensitivity threshold every time a signal of a greater magnitude is detected, to bring it onto the bar graph scale.

In either mode the buzzer will continue to sound when a signal is present, even when the signal is too small to be shown on the bar graph due to the sensitivity setting.
