Overview

Features

Automatic protection from cable voltage;
100 measurements memory;
6 000 mA*H Li-Ion accumulator;
Auto calculation and numeric indication of distance to the cable fault;
12.5 cm accuracy at whole measured distance;
Library of most common Velocity Propagations;

Application Area

The optimum solution for rapid troubleshooting of cable networks – extremely easy to operate, compact and cheap TDR tester.

TDR-TA3.3TM – a single-channel cable fault locator, designed to determine the nature and location of the cables faults (open, short, sleeve, cable splice, parallel challenge, Pupin coil).

The small size and weight make the TDR-TA3.3TM especially convenient for working in confined spaces cable wells. High precision characteristics allow to measure near and far zones.

Sphere of application

TDR-TA3.3TM is intended to measure on cables of the following types:

signal and control cables;
power cables;
aerial cable lines;
computer networks ;
TV and radio cable lines.
