Cable Route Tracer
DESCRIPTION
The AccuTrace Cable Route Tracer consists of a transmitter,
which energizes the line with a traceable signal, and a
portable receiver, which detects the signal. The transmitter
can energize the line either by magnetic induction from a
built-in antenna or by direct conductive connection to the
metallic line.
Energizing the line conductively provides increased tracing
distance and minimizes signal coupling to other lines.
Inductive coupling, which does not require a mechanical
connection to the line, permits a buried line to be traced
without uncovering or de-energizing it.
The transmitter provides a simple, LO/HI pushbutton to
adjust the transmitted signal’s strength, and a PULSE button
for battery conservation and easy identification of the
signal.
The receiver can be used to trace lines using either peaks
(detection of the maximum signal) or nulls (detection of
the minimum, or zero, signal).
The antenna is swivel-mounted foroperation in vertical,
horizontal or 45° mode used to calculate depth. The
receiver provides audible and visual indication of detected
signal strength. Simple controls adjust sensitivity and
amplification, and a jack provides for audio output to an
optional headset.Standard AA batteries provide up to
30 hours of continuous operation.
When the receiver is not in use, the telescoping handle
retracts for convenient, compact storage.
APPLICATIONS
AccuTrace locates and traces any conductive line such as
cable, pipe or metallic conduit. Depth of the line can be
established quickly by taking advantage of the swivelmounted antenna. Adding an optional ring clamp to the
system provides a stronger inductive signal for tracing in
areas with heavy cable activity. Blockages in water pipes
such as sewer lines can be found with the use of an
optional watertight capsule transmitter. A tape-on
transmitter lets the operator locate collapsed duct work.
FEATURES AND BENEFITS
■
Easy to use and simple to operate, this cable route
tracer can be used successfully the first day in the field.
■
Conductive coupling lets the operator discriminate
between multiple utility cables in a common trench and
trace the line of interest. Conductive tracing also
increases tracing distance.
■
Inductive coupling lets the signal be transmitted without
a direct metal-to-metal connection. The operator can
trace an energized cable using a distinctive transmitted
signal. Also, cables that do not have exposed
terminations can be traced with ease.
■
Both peak- and null-tracing mode methods can be used
during a single trace to ensure accuracy and speed. Null
tracing is very fast and can be used to identify sharp
direction changes. Peak tracing can be used to find the
cable at the start of the trace and to identify cable
location when conditions make null tracing ineffective.

■
Superinductive circuitry allows, in the inductive tracing
mode, the AccuTrace to trace longer lengths than any
known competitor. If conditions such as cable depth
make normal inductive tracing inefficient, the
superinductor will produce a signal that the receiver can
trace.
■
The receiver picks up only the distinctive transmitted
signal by filtering out electric noise and static.
■
Extremely loud, adjustable audio output eliminates the
need for headphones in noisy areas. This makes the
AccuTrace more comfortable and easier to use than units
requiring headphones and visual interpretation.
■
Extremely lightweight receiver increases operator
comfort when tracing long cables or when using for
extended periods.
