11.4 Using the S1 probe
11.4.1 Measuring volume
In theory, the electric and magnetic field lines penetrate the material to be measured to an
infinite depth. However, the effective penetration depth of the S1 probe, which is relevant
for measurement, is approximately 80 mm (3.15 in) (twice the distance between the
rods).

11.4.2 Accuracy
Recommended approach to achieve the best possible accuracy with the S1 probe
Perform measurements directly in piles of sand and gravel
1. Insert the probe as far as the blue probe body into the material to be measured


2. Select the "Average" operating mode
3. Take measurements at different points
 This produces a representative moisture value for the material
After a longer period of dry weather, the material will be drier at the surface than in
lower layers. However, if it has recently rained after a longer dry spell, the material at
the surface will be wetter. For the best measurement result, the moisture should be
measured at different points and at different depths.
Measurement of laboratory samples in a bucket
The following conditions must be met to achieve the best possible accuracy of results:
The entire length of the rod probes must be located in the material to be measured
