50 H2 Stationary GrainGage Calibration
4.2.2 Moisture Calibration Overview
To begin the calibration you will need one sample that is at least 6 lb (2.7 kg). Cycle this sample three times
after providing the Known Moisture. These values do not change between cycles of the same sample.
Continue the calibration with more samples. Start with the driest sample and move to the wettest. Each
sample should be cycled at least three times. After the first cycle, the moisture values can be input by
using the Last Value option.
Calibration Steps
Cycle Moisture
1 . Sample A Driest sample
2 . Cycle Sample A two more
times .
3 . Sample B
Next sample going from
driest to wettest .
4 . Cycle Sample B two more
times .
5 . Sample C Wettest sample
6 . Cycle Sample C two more
times .
Note: This table reflects the minimum number of cycles needed to create a moisture curve. To improve
your moisture curve, cycle several more moisture samples.
4.2.3 Moisture Calibration
To create a new moisture curve in Mirus for the H2 Stationary GrainGage, do the following:
1. If the grain samples have been in air conditioning or cold storage, acclimate them by spreading them
out on a clean surface in the shop overnight.
Do not
leave them in the sun to warm up.
2. Test the ambient samples in a benchtop sensor by cycling sub-samples from each larger sample 3–5
times and then average the moisture readings. This is the Known Moisture.
3. Within the hour, take the samples to the GrainGage. If you are calibrating outside, make sure the
samples stay in the shade.
