Product Description:

The Fault Mapper Pro® Model CA7026 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 Model CA7026 measures cable length, and indicates the distance to cable faults and terminations to a range of 11,700 ft or 3500m (user selectable), on virtually any type of cable of two or more conductors. The Model CA7026 shows a reflection profile of the cable under test as an oscilloscope-like trace on a 128 x 64 pixel graphical LCD. A movable cursor can be aligned with points on the trace; the distances displayed will automatically update to the cursor position.The Model CA7026 has a selectable impedance facility allowing it to be matched to the cable under test. This automatically eliminates the transmission pulse from the display, enabling easier identification of short range faults and terminations. The Velocity of Propagation (Vp) is adjustable between 1% and 99% enabling accurate calibration to the cable under test. ***The Model CA7026 incorporates an oscillating tone generator that is detectable with a standard tone receiver, for use in the tracing and identification of cables.
