The TDR500/3 is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m and a 5 km maximum range depending on velocity factor selected and cable type.
Four output impedances are available (25, 50, 75, and 100 ?) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.
