TDR-420

• fault location in power and telecommunication cables • two independent cursors to indicate two fault locations and the distance between them (TDR-420) • fault location in coaxial cables • fault location in infrastructure cables • detection of breaks, short-circuits, damage caused by moisture and other changes in cable impedance • graphic presentation of cable faults with an indication of the distance to the fault on the display 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 you to measure the length of the cable and determine the distance to 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 dead zone of 0.6 m allows you to locate damage in very short distance from connection point of device.
