Diagnose faults with TDR-420

The TDR-420 reflectometer is a handy digital Time Domain Reflectometer (TDR) designed to characterize and locate faults in power and telecommunications cables. The Sonel TDR-420 reflectometer allows to measure the length of the cable and to determine the distance to the damage or impedance change in the range from 4 to 6000 m in cables with metal conductors. The shortest measuring range of 7 meters and the dead zone of 0.6 m allows user to locate a damage in a very short distance from the connection point of the device.
