CableMaster 400

Cable tester for data, voice and coax cables

Affordable Cable Tester for your Toolbox

The CableMaster is the all-in-one tool for localizing cable faults in data cables, telephone cables and coax cables. The large LCD shows multiple fault situations and gives a “Pass” or “Fail” indication where necessary.

CableMaster 400 is the solution for testing the complex wire environment that exists in today’s information and entertainment systems. A built-in tone generator is useful for tracing faults and finding the termination ends of installed cable of all types. Using the built-in remote and wiremapper sets, one user can identify up to 19 remote and wiremapper sets.
