Get ready to start a measuring campaign<br />
Figure 4-4<br />
The water level should be<br />
2 cm in the basket.<br />
Please place the sample<br />
ring incl. saturation bowl<br />
in the basket.<br />
The cutting edge shows<br />
upwards, thus the sample<br />
is saturated capillary from<br />
the reverse side.<br />
After 4-6 h fill new water<br />
inside the basket ca. 1cm<br />
below the upper rim of the<br />
sampling ring.<br />
Important note: Slightly lift up and tilt the sampling ring with<br />
saturation attachment inside the water filled saturation bowl. This<br />
prevents that air bubbles are trapped between soil sample and<br />
mesh fabric. Do this carefully so no soil particles are flushed out.<br />
The duration until the sample is saturated and all air is removed will<br />
depend on the soil type. When saturated, the sample surface will<br />
have a glossy appearance. Clayey soil will need the longest (several<br />
days).<br />
