Mirus for H2 Classic GrainGage
67 H2 Classic GrainGage Calibration
For example, Sample One has the following moisture measurements:
• Benchtop sensor: 18%
•
GrainGage: 16.8%
The offset would be 18% − 16.8% = +1.2%
12. Average the sample offsets.
For example, if your benchtop sensor says Sample One is +1.2% more than the GrainGage measurement
and Sample Two is +0.8%, the average offset is +1.0%.
13. Add the average offset to each moisture point with exception of the 0 and 1 moisture points (never
adjust 0 or 1). Subtract for a negative average offset. Do not adjust voltages.
In the example above, readings from the benchtop sensor indicate that the samples have, on average, 1%
higher moisture than the percentages in the previously calculated moisture curve.
The following tables illustrate this type of adjustment:
