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.
