Lexxi T1660

Radiodetection’s Lexxi T1660 provides an unrivalled combination of performance, usability and economy. Radiodetection has created Lexxi T1660 by taking the easy-to-hold ergonomics familiar to users of the Riser Bond Model 1550 and Bicotest Lexxi T810 and installing a unique TDR engine and a 3.5” color back-lit display. The result is a cable tester whose 1% distance accuracy and resolution gives technicians the tool they need to find faults quickly and accurately.

The Lexxi T1660 is suitable for analysing all metallic cables consisting of at least two metallic elements, one of which can be the armouring or the screen. Cable types include CATV, twisted pair telecom, Ethernet and even LV power cables. The Lexxi T1660 is shipped with a set of 100 Ω crocodile clip Twisted Pair connection cables as standard. A range of optional plug-in modules make it adaptable to the requirements of a wide variety of industries and applications, with the Blocking Filter module allowing safe analysis of live 3-phase mains cables.
