Cable fault locator TDR with Bridge function ST620 with USB

Overview

This cable fault locator is designed for ease of use. It combines with both time domain reflectometer (TDR, pulse reflection testing ) and intelligent bridge testing (Bridge) for measuring the exact fault location such as the broken line, cross faults, earthing, poor insulation and poor contact of the lead covered cables as well as plastic cables.

It can test almost all the telecom cables. Simply select the modes which you are going to use. Distance, VOP, Gain and Rangeare automatically selected and adjusted as you scan the cable. Just move the cursor to the fault to pinpoint its location.

It is an effective tool to reduce troubleshooting time, improve work efficiency and reduce labor intensity of line maintenance staff. It also can be used in line projects acceptance and inspection of electrical cables.
