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 fault cables and terminations to a range of
11,700 ft (3500m), 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 the cursor position.
