Article Number: 226512

Affordable Cable Tester and Fault Locator

The CableMaster 500 is designed to test and measure lengths of all common low voltage cabling found in today’s network, video or telephone systems. It also maps the locations of cable ends by sending a tone on the cable that can be traced with a tone tracer or by blinking the LED on the port jack. The CableMaster 500 has a large, bright backlit LCD display and glow-in-the-dark buttons to directly access each function. The remote stores inside the main unit for ease of cable testing.
