The Fault Mapper™ Model CA7024 is
a handheld, alphanumeric, TDR (Time
Domain Reflectometer) Cable Length
Meter and Fault Locator, designed to
measure the length of electrical and
communication cables. It can also
indicate the distance to a fault in the
cable (open or short), given access
to only one end of a two or more
conductor cable.
By incorporating fast-edge step TDR
technology, the Model CA7024
measures cable length and indicates

the distance to open or short circuit
faults, to a range of 6000 ft (2000m),
on virtually any type of cable. The
Model CA7024 indicates the cable
length or fault distance and description,
alphanumerically on a 128 x 64
graphical LCD.
An internal library of standard cable
types enables accurate measurement
without the necessity of entering
Velocity of Propagation (Vp)
information, and the Model CA7024
automatically compensates for
different cable impedances.

The Model CA7024 incorporates
an oscillating tone generator that is
detectable with a standard tone
tracer for use in tracing cables and
identification of cable location.
The Model CA7024 also displays
a “Voltage Detected” warning and
sounds an alarm when connected to
a cable energized by more than 10V,
which prohibits testing.

Features
• Handheld Cable Length Meter
and Fault Locator
• Detect opens and shorts and the
distance to them from one end of the
cable
• Measure cable length up to
6000 ft (2000m) in feet or meters
• Automatic cable impedance
compensation
• Built-in library of most common cables
and their Vp (Velocity of Propagation)
• Manual selection of Vp for all cables
not found in library
• Vp setting displayed along with
length and cable type (if in library)
• Built-in tone generator for tracing
and locating cables
• Large high-visibility blue
electroluminescent backlit display

Applications
• Determine length of cables on reels,
coils or in boxes
• Determine cable runs in wall, conduit
and other surfaces
• Detect opens and shorts in cables
and the length to them
• Trace cables to identify runs
and location
