Measuring a borehole in interval mode

Lift the rods to where they will be uncoupled and take the coupling between the clamps.
Record a measurement point by pressing the Record timestamp button.

Note: Do not move the rods during the timestamp recording.

Tip: Turn off the flushing as it interferes with the measurement. After the timestamp has been taken, flushing can be turned back on, but should be kept as low as the ground conditions allow.
Uncouple the rod and place it in the rod magazine.

Tip: As the measurement is paused between the timestamps, percussion may be used to uncouple stuck threads.
Bring down the shank and couple the next rod.

Note: The left side of the display shows the lifting progress and how many rods remain to be lifted.
Before lifting the next rod length, record a measurement point by pressing the Detach a rod button.
Uncouple the rod from the drill string and continue the rod lifting process.

Note: Do not move the rods during the timestamp recording.
Continue lifting the next rod length.

Tip: Keep the lift as steady as possible and avoid any rotation during the lift. If rotation needs to be used due to e.g. collapsing ground conditions, set your machine's rotation speed below 60 RPM and keep the total rotation time to a minimum.
