PRODUCT FEATURES
2.1 Description
The Fault Mapper is a handheld, Alpha-Numeric, TDR (Time Domain Reflec
-
tometer) Cable Length Meter and Fault Locator, which is designed to measure
the length of power and communication cables or to indicate the distance to a
fault on the cable, given access to only one end.
By incorporating Fast-edge Step TDR Technology, the Fault Mapper measures
cable length and indicates the distance to open or short circuit faults, to a range
of 6000 ft (2000m) on at least two conductors.
The Fault Mapper indicates the cable length or fault distance and description
alpha-numerically on a 128x64 Graphical LCD.
An internal library of standard cable types enables accurate measurement
without the necessity of entering Velocity of Propagation (Vp) information, and
the Fault Mapper automatically compensates for different cable impedances.
The Fault Mapper incorporates an oscillating tone generator, which is detect
-
able with a standard cable tone tracer, for use in the tracing and identification
of cable pairs.
The unit also displays a “Voltage Detected” warning and sounds an alarm when
connected to a cable energized by more than 10V, which prohibits testing.
