Conductor
Two Operator Sweep - Inductive Mode
Another method of locating a conductor inductively is by means of the two
operator sweep. This method is generally used when no starting or ending point
is known for a given conductor.
To perform the two operator sweep, turn on the transmitter and receiver. One
operator carries the transmitter while the other operator carries the receiver.
Both operators line up so that both the receiver and transmitter are aligned as in
-
selves to avoid air coupling. The operators slowly move across the search area
and in the direction of the suspect conductor. The operator with the transmitter
must make sure to hold the instrument so that the ARROW on the transmitter is
aligned parallel to the suspected path of the conductor. Once the line is located
(Figure 2-5), the transmitter can then be placed over the conductor and the
conductor traced by using the same procedures as described for the one operator
sweep. It must be noted that once a conductor is located, it is up to the operator
to verify that this is the intended conductor. This may be accomplished by trac-
ing the conductor to a junction point on the conductor such as a valve, junction
