The Lexxi T1660 is an innovative cable fault locator that offers an unrivaled combination of ease-of-use and performance. Use it to analyze any metallic cable with at least two conductors (or one conductor and a screen)—great for CATV, twisted-pair telecom, Ethernet, and even low-voltage power cables.

How It Works

The Lexxi transmits electrical pulses into a cable, then measures how long it takes to receive a portion of that pulse energy back from faults or gaps in the cable. It translates this time measurement into distance, providing you with a highly accurate location of short circuits, open circuits, high-resistance joints, cable joints, changes in cable type, or the far end of the cable you’re testing.

Easy-to-Use Interface

The easy-to-use interface features just six control buttons and simple onscreen instructions for setting your preferences. A large 3.5” color backlit LCD display shows a waveform that lets you assess the type of imperfection found. It also displays transmitted and reflected pulses, distance to fault, VoP, output impedance, display range, gain setting, cursor, and battery status.
