The Megger TDR900 is an advanced 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 15 feet (5 m) to 10,000 feet (3 km) with a minimum resolution of 20 inches (50 cm).
The TDR900 can be used for any cable consisting of at east 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 25, 50, 75, 100, 125, or 150 cables. (These correspond to power, telephony, CATV, and LAN cables).
Typical applications:
Street lighting cable runs
Outside broadcasting: check temporary cable installations
Studio broadcasting: trailing camera cables, etc.
Cable drops from aerials and antenna
Stocktaking: measure cable lengths in stock, etc.
CE-Certificated
Accurate to 20 inches (50 cm) throughout the entire range
Extra-large backlit (ICON type 7 segment) LCD
Automatic output impedance control, auto-range, autozero, and auto-sensitivity allows for closely matching to a wide range of cables under test. Only V.O.P (velocity of propagation) settings required
Displays cable length if the cable’s V.O.P (velocity of propagation) is known or displays V.O.P (velocity of propagation) if a cable’s length is known
20 internal memory locations store up to 20 custom cable V.O.P settings
Internal library of 39 standard cables allow for quick and easy measurements for industry standard cable types
Tone Generator (oscillating 910 to 1100 Hz; 5 V peak to peak) for cable identification and tracing
Line Voltage Detection: Displays “OUCH” message and stops operation if line voltage exceeds 6.5 V
Safety Protection (up to 250 V RMS)
Alligator clip adapter, user manual, soft carrying case
