0-8km Hand held communication cable tester for cable path and time of fault and testing range of the fault
Introduction
The TDRL-901 Cable Fault Locator is a portable handholddevice used for locating the broken fault, cross fault, insulation fault and so on. It can be used to measure the cable length, wave velocity and distinguish the middle joints and terminals.
It is a simple locating device, adopts to kinds cable and specially, the telecomputercable.
Design Features
TDRL(Time Domain Reflectometry)method make it possible to measure broken fault, cross fault, insulation fault and so on.
Automatic measurement
Auto power-off when sleeping and low battery voltage
Friendly user interface, easy to operate
Supply by dry batter or recharge battery
Handheld device, easy to carry
