Reception Distance And What That Means - Power Probe ECT3000 User Manual

Reception Distance and What that Means.

When tracing parallel circuits, you can determine if a one wire has a stronger "Ground-
ed 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
compared to the other parallel branch. Just knowing this information can come in handy
when determining the fault of a circuit.
Once the receiver is locked into the Short/Grounded Circuit signal, (see "Locking the sen-
sitivity 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 exam-
ple, you will notice the 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 transmitting 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 confusion with other parallel wires or
circuits.
