TDR tests length and faults, generates tone

The Ranger TDR Kit from Klein Toolsmeasurescable length and locates faults in addition to generating tone, the company says. “With the time domain reflectometry spread spectrum [TDR-SS] technology, the Ranger TDR Kit eliminates measuring interference and provides accurate readings up to ±1 percent and ±3 feet,” the company says. The tool works with data, communications/video and power cable systems.

The kit measures voice, data, video, doorbell, Siamese, lamp-wire and non-metallic sheathed (NM) electrical cable, Klein says. “It can be used on an even broader amount of operating environments,” the company adds, “including Safety Extra Low Voltage [SELV] rated environments as defined by the IEC. This length measurement tester ensures compliance and identifies cable runs outside specification.”
