Designed for First Responders, the Lexxi T1660 builds on RiserBond’s and Bicotest’s decades of TDR experience to provide a cable tester whose accuracy, range and resolution gives technicians the tool they need to find faults quickly and accurately.

Featuring 1% distance accuracy and a pulse that automatically scales to match the range, Radiodetection’s Lexxi T1660 targets a wide range of cable analysis applications such as finding opens, shorts and partials, verifying cable installations and detecting cable theft.

Its 328 x 256 pixel, 3.5” colour display together with a 19,000’/6km maximum range means faults can be traced quickly and accurately.

Building on the many years of TDR experience of its RiserBond and Bicotest product families, the Lexxi T1660 has a completely new TDR engine alongside its high resolution colour display. It is housed in the easy-to-hold ergonomics familiar to users of the Model 1550 and Lexxi T810, allowing it to offer backwards compatibility with the optional plug-in modules of those earlier products. These provide connection options to match a wide range of application requirements, including twisted pair phone lines, CATV cables and even safe connection to live 3-phase mains cables via a Category IV Blocking Filter.
