DataSonde
Dual Frequency DataSonde Change Method.
The DrillTrack G2 Dual Frequency DataSondes will always operate in the low frequency operating mode
when the batteries are fitted.
In most cases the low frequency is the most reliable frequency to use. It will give a more precise locate
position and a more accurate depth than other available operating frequencies.
Though there might be cases when no low frequency signal can be received with the DrillTrack G2
Receiver, due to high interference levels.
The DrillTrack G2 Dual Frequency DataSondes allow the user to change between low and high
frequency during drilling operation, using a coded rotation sequence.
When the batteries are next replaced or the battery endcap removed for longer than ten seconds, the
DataSonde will resume operation at low frequency.
Before starting the change over to the higher frequency, it is needed to pull back to the last position
where all DataSonde information was available.
The DataSonde will change frequency using the 3 step coded rotation sequence outlined below:
1 - Set to Park, wait for “P”
and for the DrillTrack G2 Receiver to beep twice.
2 - Rotate to 3 o’clock, wait for overtilt indicated
and for DrillTrack G2 Receiver to beep twice.
3 - Rotate again to 3 o’clock,
wait for DrillTrack G2 Receiver to beep twice.
As the DataSonde changes frequency the DrillTrack G2 Receiver frequency will also change
automatically. All relevant information from the DataSonde will then be displayed on the screen.
The DrillTrack G2 Receiver can also be manually set (in the setup menu).
Confirm operation has changed to the new frequency by pressing the key on the DrillTrack G2
Receiver, which indicates current DataSonde frequency.
Note
After been powered down, the Dual Frequency DataSonde will revert back to low frequency operating
mode automatically.
Note
When using the Dual Frequency DataSonde, it is important to calibrate the DrillTrack G2 Receiver in
both low and high frequencies.
