Locking the Sensitivity for Short/Grounded Circuits.
To lock the receiver’s sensitivity for short/grounded
circuits, it must be turned on and in "Pulse Mode". Hold
the "Open and Short Pick-Up" of the receiver parallel
and as near to the wire as you can while achieving
the most rapid pulse rate (See Fig. A). Now press the
"Power/Sensitivity" button. The receiver is now locked
into the strong "Grounded Circuit signal" and will ignore
weaker parallel circuit signals. If you need to re-adjust
the receiver’s sensitivity so that it will pick up weaker
circuit signals and be more sensitive, press the "Power/
Sensitivity Lock" button to return to "Pulse Mode". This
time, hold the receiver a little farther away from the wire
so that the pulse rate is a little slower, and then repress
the "Power/Sensitivity Lock" button.
Locking the Sensitivity for Open Circuits.
To adjust the receiver so that it is at its most sensitive
setting in open circuit tracing. First turn on the receiver.
It is now in "Pulse Mode". Hold it as close to the open
circuit as you can while receiving the most rapid pulse
frequency.
Now lift the receiver about 6 inches away from the circuit
and press the "Power/Sensitivity Lock" button. (See Fig.
B) At this level you should be able to pick up the open
circuit signal in that circuit and eliminate other signals
that could be capacitive coupling into neighboring
floating circuits and causing you problems. If you need
to adjust the receiver so that the reception sensitivity
is more sensitive, press the "Power/Sensitivity Lock"
button to return to "Pulse Mode". Now hold the receiver
about 8 inches from the transmitting circuit and then
press the "Power/Sensitivity Lock" button again. Repeat
these steps until you achieve the proper setting for your
application.

Direction to the Short
The Short/Grounded Circuit signal is polarized. This
gives the receiver the information it needs to show you
the direction to the short or the direction to ground.
When you place the receiver’s "Open & Short Pick-
Up" parallel to the wire of the Grounded Circuit signal,
"Direction to Short/Ground" indicator will point you in the
direction to ground. If you were to flip the receiver in the
opposite direction it will detect the polarity change, the
"Direction to Short/Ground" indicator will flip, and it will
still point you in the direction to ground. Keep in mind
that the receiver’s "Open & Short Pick-Up" must be held
parallel to the circuit for the "Direction to Short/Ground"
to indicate.
The tester works equally well with either positive chassis
ground or negative chassis ground. The only thing you
need to keep in mind is, when tracing short circuits the
receiver always points you towards the minus of the
battery so if you have a short between your wiring and
the chassis is a positive ground system, you just need to
trace in the opposite direction the LED is pointing!
