The KLEIN TOOLS Cable Length Meter is a portable Time Domain Reflectometry (TDR) cable length tester. It measures cable length, calibrates Velocity of Propagation (VoP) values, finds the distance to faults in cables, and provides built-in tone generation for cable tracing. This tester provides accurate cable length measurement for a wide variety of cable types at an affordable price. Includes test leads and a carrying case.
