DrillTrack G2 Operating Instructions
Calibration of the DrillTrack G2 Receiver
Fit new alkaline batteries in the DataSonde, observing the correct polarity. Fit the DataSonde securely in
the drillhead/Datasonde housing. To ensure a tight fit, electrical tape or O-rings could be used.
Press and hold the
key,
and turn the Receiver on,
by pressing the
key.
Release the
key when "CAL"
appears on the Receiver display.
Position the drillhead/DataSonde housing at exactly
1metre (39 in) from the Receiver blade at a 90º angle.
If available, use the optional calibration jig.
Move the Receiver in all four directions,
keeping the distance of 1 metre (39 in),
1m (39")
until all four locate arrows appear on the screen.
To calibrate the Receiver press the
key.
A single beep and a 1m (39") readout on the display
confirms that calibration is complete.
To store the calibration in the Receivers memory, press the
key.
To exit the calibration mode press the
key.
Note:
Providing that the Receiver, DataSonde and drillhead/DataSonde housing have not been changed,
calibration should only need to be carried out once. However, it is recommended that a depth check is
carried out prior to every new bore.
