Repeat steps 2 and 3 until you have reached the desired depth.
The maximum drilling depth is approximately 115 cm.
Insert the probe into the hole according to the following procedure:
1.
Remove the auger from the hole.
2.
Insert the probe into the hole and press it down as deep as
possible by hand. Insert the probe deep enough into the soil so
that the soil/air boundary is at the ground level line. The ground
level line is marked on the sensor (see Figure 80 below).
CAUTION
Never use a hammer or other instrument directly on the head of a
probe. If too much force is applied to the probe, damage to the
electronics inside may result.
NOTE
Any delay in inserting the probe into the drilled hole may allow
moisture to swell the hole sides, or fill the hole with water.
