meter.
The instrument measures the depth of the borehole by measuring the length
of rope deployed by the main winch. The measure is not affected by the
movements of the mast when applying thrust.
Measuring borehole depth:
•
Lower the mast until its bottom is at ground level;
a. if the tool protrudes inferiorly
from the mast of a distance “s”,
start to drill slowly lowering the
mast
while
the
tool
is
penetrating into the soil
;
b. if the tool doesn't protrude from
the mast, take its base to the
same level of the mast;
•
press button Pr on joystick B to reset the display, which will show 00.0;
•
start to drill.
The display shows the depth in
metres
(the two decimals are centimetres)
1
reached from the base of the tool.
If case “a” occurs, the length “s” has to be added to the total depth.
