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 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.

• Cable length meter measures length of electrical, data, two-wire and Romex® cables up to 3000 feet (914 m).
• TDR technology measures Distance-to-Fault, Open or Short, on terminated or unterminated cable.
• Programmed with Velocity of Propagation (VoP) values for Coax, Data, Romex® and other multiwire cables for accurate length measurement within +/-(2-Percent plus 3-Foot/0.9 m) accuracy.
• Stores custom cable VoP values for consistently accurate results and time savings.
• Simple interface with full color, interactive LCD.
• Tones unenergized, open-ended wires for wire tracing (requires Analog Probe (Cat. No. VDV500-123, sold separately).
• Coax-BNC or high quality alligator clips for quick, easy connection to test most cable types.
• RJ45 jack for accurate length measurement of terminated data cables.
• Measurements can be switched between and metric and imperial units.
• Includes padded carrying case and leads.
