T
he MultiTool Cable Tester
quickly finds faults in cables up
to a distance of 2500 ft. (762 m).
This versatile tool is a favorite
with contractors, electricians,
low-voltage installers, and with
anyone installing or maintaining
metallic cables.
Use the tester to find cables
damaged during or after
installation. The damaged section
is often hidden behind walls,
above ceilings, or buried
underground. You can also use
the tester to determine the length
of cable remaining on a spool or
in a box.
Here’s how it works: Using
Time-Domain Reflectometry
(TDR), the Tester measures the
distance from one end of the
cable to a fault or measures the
length of a cable, by transmitting

Pinpointing shorts and opens is easy
with this versatile tool!
Key Features
MULTITOOL CABLE TESTER
high-frequency pulses and
examining their reflections along
the cable. It determines how long
a cable is based on the
time
that it
takes the transmitted signal to be
reflected
back and how strong
the signal is.
To operate the tester, simply
select the appropriate cable type
from the built-in library of over
sixty cable types, then attach the
test leads to two conductors of
the cable. Press a button to
display (on a single screen) the
length of the cable and the
distance to an open or short.
When multiple runs are being
installed in the same area, the first
run can be measured to
accurately determine the total
amount of cable required to
complete the job. If you check
cable inventory before starting a
job, you won’t have to go out and
buy more cable in the middle of a
job.
The tester also works with
standard tone probes for tracing
cable. Suppose you have a large
telecommunication closet with
hundreds of cables in bundles. If
you have a group of 20 or 30
cables coming out of a ceiling, it
might be difficult to determine
which one is coming out of an
office next to the closet. The
MultiTool Cable Tester can act as
a tone generator (in conjunction
with a tone probe, ordered
separately) to “trace” or find the
correct cable in the bundle. A
tech at one end of the cable can
induce a tone onto a cable (via
the tester) and a tech at the other
end can find that same cable by
waving a probe near the cable
bundle.
