Handling Collected Material Samples
To create an accurate calibration it is necessary to collect samples of the material as it passes
over the sensor and, at the same time, record the Average Unscaled value from the sensor
during the material collection period. To ensure the material collected is accurately analysed
to determine the moisture content it is imperative that the material is collected as close to the
sensor as possible and sealed in an air tight container/bag immediately after collection. If the
material is not sealed in an air tight container/bag moisture will be lost before it is analysed.
The container/bag must only be opened when the laboratory tests are to be performed.
If collecting hot material (i.e. from the outlet of a dryer or in hot environments) the material
MUST be sealed into the container/bag and allowed to cool to room temperature before it is
analysed. Once it has cooled the container/bag must be shaken to enable any moisture on
the surface of the container to be mixed back into the material. Removing the material before
it has cooled will result in moisture loss due to evaporation and will introduce potential errors
to the calibration.

Collecting Samples
To collect samples and record the associated Average Unscaled values from the sensor
follow the procedure detailed below:
1. Connect to the sensor using Hydro-View and open the calibration section. If more
than one sensor is connected select from the list displayed.
2. Create a new calibration by selecting “New Cal”.
3. Enter a calibration name and configure the Calibration Type, Tolerance, Measurement
Mode (if available) and Quick Start Rules (if applicable).
4.
Select the “Edit Points” button to start entering the calibration data.
