  • Page 18: Configuring Soil Profiles

    HS2 and HS2P These parameters are soil specific and grouped as “soil profiles”. The HydroSense II holds up to 10 soil profiles labeled “SOIL 1” through “SOIL 10”. Some soil profiles are preset to default values. These values may be used or overwritten as desired, but take care to record what soil type is used for each profile.
  • Page 19 HS2 and HS2P A soil profile page will be displayed. This page shows the reference values stored for this soil profile and the rod length used. To select this soil profile to apply to the current measurement, press highlight SELECT THIS SOIL and press New reference values can be set from the soil profile screen.

    EC. The calibration coefficients to convert measured time of travel to dielectric constant and water content are contained within the sensor head and are the intellectual property of Campbell Scientific. 6.4.4.2 Rod Insertion For accurate, repeatable measurements, the rods of the sensor must be fully inserted into the soil.

  • Page 21: Soil Factors Affecting Measurement

    HS2 and HS2P Soil is not homogeneous. Cracks, rocks, pore size, plant roots, and texture layers are not usually distributed uniformly throughout a measured profile. If the water content over a large area such as a cropped field is to be determined, several measurements may be required to establish a representative measurement.
