Problem 4: Incorrect Depth readings.
1- Calibrate the Receiver to the DataSonde (while in the drillhead/DataSonde housing).
2- Check the DataSonde operation in the drillhead/DataSonde housing before going underground.
3- Check the slotting arrangements in the drillhead/DataSonde housing. The slots should be approximately
150% of the length of the DataSonde antenna section, and line up longitudinally along the
drillhead/DataSonde housing, directly above the DataSonde. A minimum of four slots equally spaced
around the drillhead/DataSonde housing is required. Wrong length and or position of the slots can greatly
affect the DataSonde signal range and battery life.
4- Check if the Receiver is set to Metric or Imperial units.
5- Use a Radiodetection locator to check for interference from buried utilities.
Problem 5: Receiver will not calibrate.
1- Move the Receiver and drillhead/DataSonde housing with DataSonde to a more interference free location
and try again.
2- Make sure that the calibration distance between Receiver and center of the drillhead/DataSonde housing is
exactly one metre.
3- Check the slotting arrangements in the drillhead/DataSonde housing.
Problem 6: Data lost.
1- Check that the drillhead/DataSonde housing has not exceeded the DataSonde signal range.
2- Check if the DataSonde data can be regained by pulling back to the last locate point.
3- Excessive shock/vibration can cause the DataSonde to temporarily shut down.
Wait ten minutes. Make sure the DataSonde has been adequately protected inside the
drillhead/DataSonde housing against shock/vibration.
4- High DataSonde temperature may have caused lost of signal. Check temperature overheat indicator
on the front of the DataSonde.
5- Replace the DataSonde batteries.
