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.

The Fault Mapper Pro

®

incorporates an oscillating tone tracer,

which is detectable with a standard tone tracer, for use in the

tracing and identification of cable pairs.
