8. Add the average offset to each moisture point with the 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 grain samples above 26% have,
on average, 1% higher moisture than the percentages in the base moisture curve. Therefore, in the curve:
•
26% would become 27%
•
28% would become 29%
• 40% would become 41%
The lower and upper ends of the newly adjusted moisture curve should graphically depict a smooth point-
to-point transition (as illustrated below). If it isn’t smooth, HarvestMaster recommends generating a new
curve.
9. Once the curve is adjusted, recheck samples, starting with the lower half of the moisture curve.
10. After adjusting the lower half of the curve, cycle samples above 26% and repeat the adjustment
procedure (steps 1–8 above). Only adjust the points above 26% and leave the points on the lower half
alone.
In some cases, the higher the moisture, the steeper the
slope of the curve. This is indicated by a steady increase
in the difference between the moisture curve and
the moisture percentages in the grain samples as the
moisture values increase.
This scenario is not uncommon in high moisture corn. It
requires adding extra percentage points as the moisture
value increases. For example, adding the following
percentages to the default curve will help match the
steeper slope in higher moisture grain samples:
•
Add 1% to moisture values 26% to 27%
•
Add 1.5% to moisture values 28% to 30%
•
Add 2% to moisture values above 30%
