Pipehorn 570 Signal Clamp
570 Signal Clamp
For use with Pipehorn 800 Series Transmitters
OPERATING INSTRUCTIONS
Use the Signal Clamp when direct connection is not possible but you can position a clamp around an accessible
target conductor. It applies a relatively stronger signal to the target conductor. The clamp can be used on
conductors of 5 inches (12.5 cm) or less in diameter. A threaded fitting on the clamp handle and a remote control
jaw actuator are provided for use with an extension handle (hot stick) for long reach applications.
DANGER! SHOCK HAZARD
CONNECTING DIRECTLY OR CLAMPING TO ANY CONDUCTOR CAN BE HAZARDOUS AND RESULT IN
ELECTRIC SHOCK, INJURY, OR DEATH. ONLY LICENSED OR AUTHORIZED PERSONS SHOULD
WORK AROUND POTENTIALLY ENERGIZED CONDUCTORS.
Clamp around the target conductor below the electrical ground (as shown in Figure 1) making sure the
jaws on the signal clamp meet squarely and are fully closed. The better the jaws meet, the more signal will
be applied to the target conductor.
To insure that the Transmitter signal reaches the Receiver, the path between the point where the signal is
applied and the point where it is received must be complete. If you suspect a break in this path, look for
disconnectted leads, circuit breakers, and open switches. It is essential to provide a good electrical insu-
lator, such as a gas pipe at a meter, ground the conductor below the insulator, as shown in Figure 1 (over).
A weak signal may be due to a poorly grounded conductor. Power lines and telephone sheaths are usually
grounded on both sides of the Signal Clamp as in Figure 2 (over).
