To begin saturate the soil samples with degassed, deionized water. After setting up the tensiometers and the sensor, place the saturated sample and the corresponding saturation plate on a working surface. Place the auger guide on top of the sample ring.
Insert the tensiometer shaft auger into the hole of the auger guide, and turn it completely to remove soil. Then remove the auger guide and ensure that the soil sample has not collapsed in the hole. Remove the silicon bulbs from each tensiometer and place the silicon disc on top of the sensor unit.
Place an absorbent material such as a towel under the connected sensor unit. Invert the sample core and place it on top of the sensor unit, fitting the sample onto the tensiometers. Next, remove the coffee filter and saturation plate.
Secure the soil core with metal clasps on the side of the sensor unit.
