CONTROL PANEL cont.

TOUCHPAD CONTROLS ARE AS FOLLOWS:

GND GRAB: Ground Grab.

The control allows you to set the detector’s internal ground setting equal to the phase of the ground you are searching over.

See the section on Ground Balancing for a more thorough explanation of this feature and the reason for using it.

Press-and-hold the GND GRAB touch pad to invoke automatic ground balancing. This will “grab” the ground value.

In order to determine the most accurate ground value, pump the coil up and down over the ground while standing in one place over a patch of ground free of metal.

1:Start with the coil 6” above the ground; lower it to about 1” from the ground.

2. Continue this pumping motion until all of the bars in the “GROUND ERROR” window disappear.

3:At the point where the GROUND value at the bottom right of the screen stop changing, the detector has correctly measured the ground’s phase.

4:Immediately release the control pad to set the detector’s internal ground setting value equal to the last GROUND value displayed.

If you wish to manually change the detector’s internal ground setting, press the or touchpads. Note that each 10 presses of these touchpads will change the displayed setting by only 1 number. The detector actually has 1,000 different ground settings to choose from, but uses only 2 digits to display the number. Reasons for this manual ground balancing feature are explained in the Ground Balancing section of the manual.

FREQ: Frequency Selection

Use this control if detector behaves erratically and you suspect electromagnetic interference from some other electronic device. This control will change the detector’s operating frequency. Press until you find one of the frequencies which minimizes the interference.

λChoices are:

λ- default frequency λ- 1st alternate frequency

- 2nd alternate frequency

Changing frequency may require you to change the ground balance setting. See section on ground balancing.
