Figure 76 Cleaning the Auger with a Screwdriver

4. Repeat steps 2 and 3 until you have reached the desired depth. The

maximum drilling depth is approximately 1.15 m (45 in.).

Inserting the Sensor into a Hole

Insert the sensor into the hole according to the following procedure:

1. Remove the auger from the hole.

2. Insert the sensor into the hole and press it down as deep as possible

by hand. Make sure that there are no sharp stones or other objects

in the ground that could press the sensor. Refer to Figure 77 on

page 89.

WARNING

Do not use fingers to clean the auger. The edges are sharp.

CAUTION

Do not drive or press sensors directly into soil of unknown

composition. Always make a pilot hole prior to sensor insertion, unless

the soil consists of homogenous, loose sand.

CAUTION

Never use a hammer or other instrument to hit the sensor. If too much

force is applied to the sensor, damage to the electronics inside may

result. Note that sensor warranty is void if a hammer or unapproved

tool is used to drive the probe into the soil.
