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.
Features
Fault location in power and telecommunication cables
Two independent cursors to indicate two fault locations and the distance between them
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
