The Fault Mapper Pro® 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 ft (3m) to 19,000
ft (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 (Vp) is
adjustable between 1% and 99% enabling accurate calibration to
the cable under test.
The Vp value is expressed as a percentage of the speed of light
(e.g. 67% or ft/mtrs/micro-second), this value will vary according
to the type of cable under test. The Fault Mapper Pro® can accept
user selectable values between 1 and 99% (or the equivalent value
in feet or meters per micro-second).
Based on the selected Vp and the time taken for the pulses to
travel through the cable, a reflection profile of the cable under test
is displayed. An adjustable cursor assists in locating faults and
termination.

*Measurement accuracy of ±1% assumes the instrument setting for velocity of propagation (Vp) of the cable under test to be accurately set, and homogeneity of the velocity
of propagation (Vp) along the cable length. Accurate positioning of the cursor is also required.
