4. Backfill the trench taking care to pack the soil back to natural bulk density around the sensor
body.
4.1.2 Vertical Installation
1. Drill a 3-in hole to the depth at which the sensor is to be installed.
2. Insert the sensor into the undisturbed soil at the bottom of the drilled hole using a hand or any
other implement that will guide the sensor into the soil at the bottom of the hole.
3. After inserting the sensor, backfill the hole, and take care to pack the soil back to natural bulk
density while not damaging the overmolding of the sensor and the sensor cable in the process.
Installation Note:
Abnormal data may show up if sensor prongs are exposed in the air.
It is possible to get sticks, bark, roots or other material stuck between the sensor prongs,
which will severely affect the sensor data readings. Any air gaps or excessive soil compaction
around the sensor can also influence the readings.
Do not install the sensor adjacent to large metal objects.
Be careful when inserting the sensor into dense soil, as the prongs will break if excessive
sideways force is used.
When installing the sensor in a lightning prone area, please check your lightning protection.
When removing the sensor from the soil, do not pull it out of the soil by the cable. Doing so
may break internal connections and make the sensor unusable.
