Assembling The Sensor Unit And The Soil Sample - UMS HYPROP Operation Manual

Assembling the sensor unit and the soil sample

Drilling the holes

Set tensio shaft adapter onto the
saturated soil sample in the tray.
The small hole should be above
the sample ring number. This makes
finding the right position easier when
the sensor unit and the soil sample
are assembled.

Use the tensio shaft auger to drill the
holes. Carefully drill in 10 mm steps
and make sure the soil sample is not
compressed.
Fill drill holes with water to make sure air
will not be pressed into the soil sample
during assembly.
