When the Receiver is in "pulse mode":
1. It detects both "grounded" and "open" circuit signals.
2. It picks up and determines strong from weak signals by the pulse frequency rate.
3. The sensitivity is ready to be locked in, by pressing the "Sense Lock / Sense Low" button.
4. It detects and displays the direction to ground or a short circuit.
While in "pulse mode" and then pressing the "Sense Lock / Sense Low" button, the receiver's sensitivity will now be locked and no longer be
in "Pulse Mode".
The Receiver's Reception Sensitivity:
When the receiver is in "pulse mode" you can lower it progressively closer to the transmitting signal and hear the increase in the pulse frequen-
cy as it passes each of the 8 sensitivity levels. The fastest pulse frequency is when you are nearest to the transmitting signal. Once you press
the "Sense Lock / Sense Low" button the reception sensitivity is locked into that distance (plus/minus a couple of inches) from the transmitting
circuit.
In order to lock the reception sensitivity of the receiver, two conditions must be met.
1. The receiver must be in "Pulse Mode".
2. The receiver must be receiving a signal
When these two conditions are met, you can now press the "Sense Lock / Sense Low" button to lock the dis-
tance of the receiver and reception sensitivity.
Adjusting the receiver's sensitivity:
Pressing either the "Sense High' or "Sense Low" buttons on the receiver will either increase or decrease the receiver's sensitivity distance. The
"Sense Level" LED bar graph display indicates the set sensitivity range. Eight LEDs lit means the most signal range and will pickup signals up
to approx. 8 inches. One LED lit means the least signal range, approx. 1 inch. This can be changed at any time after the intitial signal lock, and
can be used to approximate the distance from the receiver that the problem wire is. This feature can also be used to increase and decrease the
signal tolerance as you trace a circuit through a vehicle. You may have to increase range to read through a larger obstacle, while a tighter range
will allow you to follow individual wires or circuits more accurately.
