Low-voltage cable tester Using time domain reflectometry, the TRD900 auto-ranging, fault-finding instrument can measure power, telephony, CATV and LAN cable lengths, and find the distance to an open or short. The instrument features an internal library of 39 standard cable types, and it functions with any cable consisting of at least two insulated metallic elements, one of which can be the sheath
Low-voltage cable tester
Using time domain reflectometry, the TRD900 auto-ranging, fault-finding instrument can measure power, telephony, CATV and LAN cable lengths, and find the distance to an open or short. The instrument features an internal library of 39 standard cable types, and it functions with any cable consisting of at least two insulated metallic elements, one of which can be the sheath or shield of the cable. It has automatic output impedance control from 25 ohms to 150 ohms and a measurement range of 15 ft to 10,000 ft with a minimum resolution of 20 in.
