The Megger TDR900 is an instrument capable of measuring cable lengths and finding distance to an open or a short using time domain reflectometry. It offers exceptional features and a range capability normally associated with far more expensive instruments. The measurement range spans from 5 m to 3 km with a minimum resolution of 50 cm.
The TDR900 can be used for any cable consisting of at least two insulated metallic elements, one of which may be the sheath or shield of the cable. The Meter has automatic internal matching networks to allow testing of 25Ω, 50Ω, 75Ω, 100Ω, 125Ω, or 150Ω cables. (These correspond to power, telephony, CATV, and LAN cables.)
