The Fluke Networks 26500090 TS90 Cable Fault Finder is an easy-to-use, competitively priced tester. It is a three tools in one - a fault locator, a cable and wire manager and a tone generator with SmartTone technology. From just ONE END of any two or more conductor cable you can measure up to 2,500 feet (762 meters). Easily find the distance to opens or shorts on electrical wire, telephone wire, security wire and coax.

Results appear as a distance reading rather than a waveform, so it's perfect for technicians unfamiliar with Time Domain Refractometry (TDR). Find and fix cable problems without pulling new wire or blindly cutting into walls. Intermittent faults are easier to find because the unit constantly measures while "On."

The 26500090 TS90 is perfect for inventory management of cable stock in trucks and warehouses and it can help you generate more accurate bids for jobs by quickly assessing needs and managing the cable stock with greater accuracy.

Patented SmartTone technology gives you five distinct tones to use for exact wire and pair identification, even in proximity to current-bearing cable. When touching the wires together and momentarily shorting the far end of a cable pair, the SmartTone technology will change the cadence of the tone generated. This tone change you hear through a probe positively verifies the correct wire pair.

Voltage detection in the unit will immediately sound an alarm if you accidentally clip onto an energized pair, up to 250V AC.
