Martindale
FD550 Digital Fuse Finder

The Martindale FD550 is a digital fuse finder kit, with microprocessor controlled multi-level sensitivity for fuse and breaker identification. The 6 segment bar graph shows progressive indication of the signal strength, allowing for even faster identification. In addition, the Elite Fuse Finder also incudes a non-contact voltage indicator.

There are two modes of operation for the FD550:

• Automatic Mode: Has a memory & auto adjusting of sensitivity for foolproof identification
• Manual Mode: Allows for rapid fuse finding using the bar graph

Each Martindale FD550 fuse finder is supplied with a receiver, transmitter, batteries and instruction manual.
