Reception Distance and What that Means.
When tracing parallel circuits, you can determine if a one wire has a stronger “Grounded
Circuit signal” present over another wire. The wire that has a stronger signal carries a larger
current. This means the circuit that has the stronger signal also has a lower resistance com-
pared to the other parallel branch. Just knowing this information can come in handy when
determining the fault of a circuit.
Once the SMART receiver is locked into the short/Grounded Circuit signal, (see “Lock-
ing the sensitivity of short/grounded circuits”) note the distance of the pick-up area to the
wire as you slowly lower it down near to the wire. For example you will notice the SMART
receiver’s indicator comes on about 2 inches with one
wire and 3 inches with the other wire. The wire that
makes the receiver come on 3 inches away is transmit-
ting a stronger signal than the circuit that makes the
receiver come on only 2 inches away.
That’s important to know so you can understand and
determine which wire has a stronger signal.
This is why it is always recommended to isolate your
troubled circuit. Isolating your circuit insures that you
are following the correct circuit and it avoids confu-
sion with other parallel wires or circuits.
