H2 Classic GrainGage Calibration
4.4.9 Manual Calibration Using Excel
Note: This section is only applicable to the EM moisture curve.
HarvestMaster provides a spreadsheet for creating a two-point calibration online. It can be downloaded
www.harvestmaster.com/data/files/mirus/EM2 Sample Curves 2018.xlsx
. Follow the instructions in the
spreadsheet for creating the curve.
4.4.10 Calibrate High Moisture Corn
Note: This section is only applicable to the EM moisture curve.
When calibrating with high moisture corn samples, some moisture curves do not follow a linear voltage
relationship. HarvestMaster recommends manually adjusting the upper half of moisture curves with grain
samples above 26%.
To do this type of adjustment, start by using samples below 26% moisture to create a base curve as
described in
4.4.3 Chamber Calibration Overview on page 52
Once you have a base curve, use 3–5 samples (multiple samples required) that are 26% and above to
manually adjust the top half of the curve:
1. With the moisture curve open, cycle samples above 26% through the GrainGage 3–5 times each.
Average the moisture readings for each sample.
2. Calculate the moisture percentage offsets.
The offset is the difference between the benchtop sensor’s moisture measurement and the GrainGage’s
moisture measurement.
For example, Sample One has the following moisture measurements:
•
Benchtop sensor: 33%
•
GrainGage: 31.8%
The offset would be 33% − 31.8% = +1.2%
3. If the average readings of the higher moisture samples do not match the moisture curve, average all
the sample offsets.
For example, if your benchtop sensor says Sample One is +1.2%, Sample Two is +0.8%, and Sample Three is
+1.0%, the average offset is +1.0%.
