SubSurface Instruments Wireless Inductive Clamp User Manual page 6

The Wireless Inductive Clamp is used to induce a tracing signal on a target conductor when direct connection
is not possible, and/or when services cannot be interrupted.
Induction coupling may be better than direct connection at applying selective signal to a target conductor
with less inadvertent coupling to adjacent lines. It is common for the target conductor to carry the strongest
signal, and non-target lines will carry a weaker signal.
Successful coupler operation requires an insulated conductor that is grounded on both near and far ends.
It is best to leave the system grounds intact, or ground the line if possible, when coupling signal. Note: An
insulated conductor may be traced without near and far end grounds if a sufficient length of cable is buried
underground on either side of the point of coupling. In this case the signal will capacitive couple to ground.
• Turn the Clamp ON and select the desired frequency and output power.
• Clamp the coupler around the cable with the coupler around the wire closer to the outgoing cable, not
near the system ground. The result will be a stronger signal.
