Megger TDR1000/3p-HANDHELD TDR

With built-in blocking filters and fused test leads, the TDR1000/3P is a compact, hand held 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 Ω) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements

The TDR1000 has a simple selection option which together with a 4 way control switch offers an intuitive operation for the user.
