FEATURES

The Klein Tools Ranger™ TDR is a portable time domain reﬂ ectometer

(TDR) and voice-data-video cable tester. It measures cable length,

calibrates Nominal Velocity of Propagation (NVP) values, ﬁ nds faults in

cables, and provides built-in tone generation for cable tracing.

•

±1% and ±3 ft (1 m) length accuracy.

•

Stores up to two NVP values.

•

Displays length reading in feet or meters.

•

Extra large seven-segment, back-lit LCD screen.

•

Tests most types of copper cable including data, voice, video, lamp

wire, siamese, and NM cables.

•

Discovers NVP values for cables with known length.

•

Automatic pre-test voltage checks.

•

Identiﬁ es cable faults.

•

Tone generator with selectable tone cadence to easily trace cables

with an analog tone probe (not included).

•

Conserves power and supports long battery life with auto power off.
