Using the Coupler Clamp
Model 58 HPN 56212309 (optional)

Another direct means of energizing the conductor is with a coupler clamp. This
device can be used with the transmitter to apply the signal to the conductor, or

conductors when they are selectively energized at the transmitter location. When
it can be used, the coupler clamp is a very accurate means for tracing and identi-

1. INSTRUCTIONS FOR SINGLE COUPLER CLAMP USE: Before using

the coupler clamp, refer to the coupler clamp applications section which
starts on the next page.

a. Plug the coupler clamp into the appropriate output jack on the transmit-

ter.

b. Turn on the transmitter.
c. Attach the coupler clamp around the conductor to be traced making

sure the “jaws” of the clamp are fully closed. The contact points of the
coupler clamp must not touch the conductor.

d. Turn on the receiver and begin the search allowing the receiver to

guide you to the conductor per instructions under Using the Sure-Lock
Receiver in Chapter II, page 26.

2. USING DUAL COUPLER CLAMPS: This method of operation is espe-

cially useful for energizing and identifying a conductor running with other
conductors, i.e., manhole-to-manhole traces, manhole-to-cable vault, etc.

To utilize this method, two coupler clamps are necessary and direct access
is required at both the transmitter and receiver locations.

transmitter and turn the transmitter on.

c. Plug the second coupler clamp into the “ACCESS” jack located on the

front of the receiver and turn the receiver on.

d. Now begin to search for the energized conductor by attaching the

coupler clamp around the conductor(s) in question and observe the SPI
readings on the display. The conductor showing the highest SPI will be
the conductor being energized by the transmitter at the other end of the
locate run.
