User Guide

The clamp is not designed to provide high voltage
isolation and protection. Do not use where a danger
of high voltage contact is present.
3. Determine the correct equipment for the application.
The Inductive clamp is most commonly used on:
• Telephone cables
• Power cables
• CATV cables
• Pipes.
• Equipment for other applications can be found by
consulting the Ridge Tool Catalog, on line at
www.RIDGID.com or by calling Ridge Tool Tech-
nical Services at 800-519-3456.
4. Make sure equipment has been properly inspected.
5. Be sure the conductor to be traced is grounded at
both ends.
NOTE: No ground stake for the transmitter is required
with an inductive clamp.
6. With the transmitter powered off, insert the plug into
the jack on the back of the line transmitter. Make
sure the plug is fully inserted. If using with the
RIDGID SeekTech ST-33Q be sure the clamp has
the following label to meet the ST-33Q output re-
quirements. The label can be found on the inside of
the clamp handle.
Do not handle the transmitter while you are connect-
ed directly to ground to reduce the risk of electrical
shock.
7. Clamp the jaws around the target conductor, making
sure the jaws are fully closed.
Set-Up and Operation
WARNING
Always wear eye protection to protect your eyes
against dirt and other foreign objects.
Set up and operate the inductive clamp and work
area according to these procedures to reduce the
risk of injury from electric shock, and other causes,
and prevent inductive clamp damage.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite.
If present, do not work in area until sources have
been identified and corrected. The inductive clamp
is not explosion proof and can cause sparks.
• Clear, level, stable dry place for equipment and
operator. Do not use the equipment while standing
in water.
2. Inspect the line to have a signal applied to it.
The clamp should only be used on insulated con-
ductors. When using the clamp, the target conductor
should be grounded at each end. Otherwise, the sig-
nal may not be strong enough to locate. When apply-
ing the clamp between two grounded points, the
signal will only be on the section between grounds
(See Figure 3) .

Figure 3 – Using the SeekTech Inductive Clamp
The jaws of the clamp must be completely closed around the conductor to apply a signal. For optimal signal strength,
place clamp around the conductor between two grounded points.
