The Fluke Networks TS90 Cable Fault Finder TDR with built-in analog tone generator locates open and short circuits, measures cable length, isolates individual wire pairs, detects AC voltage on the line.
The Fluke Networks TS90 Cable Fault Finder TDRs VOP (velocity of propagation) can be adjusted from 20 to 99 to match a cables specifications and the default setting of 66 is suitable for most applications. This TDR (time-domain reflectometer) finds the distance to open and short circuits in up to 2500 feet of cabling for the TS90 model and in up to 3,000 feet of cabling for the TS100 models. It detects AC voltage, beeping to indicate a short circuit or voltage greater than 15VAC. The analog tone generator sends a signal through wires for locating and tracing wires with a probe (sold separately), and has five distinct SmartTone cadences for isolating individual wire pairs. During testing, the tone generator injects a tone into the cable and the SmartTone feature allows that tone to be modified to any of five distinct cadences for isolating individual wire pairs. It is compatible with most 1 kHz tone probes (sold separately) for detecting the generated tone. To conserve battery power, it turns off automatically after five minutes of inactivity when not connected to a cable and after one hour if connected to a cable. It has a four-digit LED display for viewing readings, is made of high-strength ABS plastic for durability and impact resistance, and has an internal coating to protect internal components against moisture. The included test lead set attaches to the TDRs female BNC (Bayonet Neill-Concelman) connector. Additional specifications include length accuracy which varies according to the cable length being tested and various environmental operating conditions. TDRs are used by network and telecom technicians and installers to troubleshoot, maintain, and optimize performance of VDV (voice, data, and video) cabling.
