The precision TDR(Time Domain Reflectometry) meters are advanced instruments capable of measuring cable lengths and finding distance to an open or a short using Time Domain Reflectometry. They offers exceptional features and a range capability normally associated with far more expensive instruments.

Model 901 is specially designed to speed up the onsite testing of data networks and production testing of cable assemblies. The meter quickly tests shielded and unshielded LAN cables and identifies all commonly found wiring faults including : Open Pair, Shorted Pair, Crossed Pair, Split Pair, and Reversed Pair. Digital display shows these 5 common wiring faults and the provided 1 Female RJ45 to Female BNC remote identifier will make wiremapping a breeze.
