Verifies cable continuity, identifies wiring faults, and determines line polarity and voltage

A highly practical network installation and troubleshooting tool which features a single or multi-tone signal, two test leads and a 4-conductor modular cable. The tone generator's signal is easily traced by the probe, even when cables are in a bundle or hidden in a mess of punchdown blocks or wall plates. This system verifies cable continuity, identifies wiring faults, determines line polarity and voltage in network (Cat5 and coax) and modular telephone lines without damaging cable insulation.The probe includes a tone amplifier and an LED indicator that detects audible frequency tones for accurate tracing and identification of wires.Compact yet easy-to-use.Includes: a 2-position switch for single tone or multi-tone signals, a toggle switch to control 3 modes of operation, a 3-color LED indicator display for telephone line polarity, continuity and voltage testing, black and red testing leads and a standard 4-pin modular cable for individual wire tests or modular jack tests, a special inductive plastic tip which prevents accidental shorts (possible with copper-tip tracers) when using near high voltage devices, an adjustable volume level for various work environments, both an amplifier and LED for loud or dark work environments, and a power switch to prevent battery drain.
