Dyna-Coupler Clamp
If a direct connection to the target facility is not possible, use the
Dyna-Coupler clamp to apply the locating frequency on the metallic
target conductor . In order to trace a target using this method, both
ends of the target must be well grounded .
1 . While the transmitter is off, attach the coupler cable to the
Dyna-Coupler clamp and plug it into the output jack of the
transmitter .
2 . Clamp the Dyna-coupler around the metallic target . The jaws of the
coupler must be fully closed .
3 . Select 8 kHz or 82 kHz on the transmitter by pressing the
frequency key .
4 . Select High Output level when using a 3-watt transmitter, or High
Output or Max Output level when using a 12-watt transmitter, for
the best signal-to-noise ratio .
5 . Trace the signal path with the receiver .
