The Fault Mapper Pro? Model CA7027 is a hand-held graphical TDR Time Domain Reflectometer designed for identifying and locating faults on power and communication cables, given access to one end only.
The Fault Mapper Pro? measures cable length and indicates the length and distance to cable faults to a range of 9 to 19,000′ (3 to?6000m) on virtually any type of cable. It injects a series of pulses into the cable under test. The velocity at which the pulses travel is determined by the type of cable, which is known as the velocity of propagation (Vp) of the cable. The Velocity of Propagation is adjustable between 1% and 99%, enabling accurate calibration to the cable under test.
Model CA7027 – Cat. #2127.84: Includes a soft carrying case, set of (2) color-coded 4 ft (red/black) leads, test probes, alligator clips, (4) 1.5V AA batteries and a user manual.
