Introduction
Thank you for selecting the Extech CLT600 Cable Locator and Tracer. The
system allows you to easily locate cable faults, diagnose and trace cables and
circuits, test AC outlet wiring, detect faults in floor heating systems, perform
non-contact voltage detection on energized circuits, locate fuses or breakers
on panels, and more.
The CLT600 includes a Transmitter that can measure voltage and inject signals through cables or pipes, and a Receiver for tracing the transmitted signals. The Receiver also detects voltage in the non-contact voltage detection
mode.
These instruments are shipped fully tested and, with proper use, they will provide years of reliable service. Please visit our website (www.extech.com) for
additional information including the latest version of this User Manual and
Customer Support.
