5) If the signal is strong enough to cause all 4 red LEDs to glow,
the GAIN knob should be rotated in a counterclockwise
direction until only 2 or 3 LEDs are lit. Lowering the GAIN
permits the 2007 to zero-in on the only hot wire or neutral of the
circuit being tested.
NOTE: Since any wire carrying the load from the transmitter
will have the magnetic signature around it, both the hot and the
neutral will carry the signal.
6) The breaker or fuse providing the strongest signal (lighting the
most LEDs) is the one powering the transmitter, and hence, the
receptacle or device to which it is connected.
If there is any doubt as to which is the correct breaker of fuse
(due to unusual breaker design, wiring, or the possibility that
two breakers are feeding the same circuit) remove the panel
trim and check the wires.
NOTE: If the hot and neutral are close together as in a conduit
or multi-conductor cable, the electrical signals tend to cancel
each other out. Although the PowerFinder receiver is sensitive
enough to trace the signal at short distances from the conduit
or cable in question, maximum distance is acquired by separat-
ing the current paths.
"Separating the current paths" simply means drawing current
through the cable or conduit in one direction by using a remote
ground path as shown in the following diagram.
