MARTINDALE FD550 Elite Fuse Finder

The Martindale Elite Fuse Finder receiver FD550 brings microprocessor controlled multi level sensitivity to fuse and breaker identification. A 6 segment bargraph gives progressive indication of signal strength allowing even faster identification. In addition the Elite receiver includes a non-contact voltage detector and can operate in two modes:
Automatic, which has a memory and the ability to automatically adjust sensitivity for foolproof identification.
Manual mode, which allows very rapid fuse finding using the bargraph.
