Combine Calibration
Crop yield is a calculated value; calibration is performed to ensure that the
sensor data and the operator input are properly used by a monitor to produce
a final output in units of bushels per acre (or kilograms per hectare).
Calibrating your combine ensures accurate data for your mapping system.
However, if you calibrate midway through a field, your maps will show yield
variations due to a revised calibration factor rather than a trend in the field. You
can fix this variation using the combine calibration feature within JDOffice.
Harvest data collected after calibrating will reflect the new calibration factors;
data that was collected prior to the calibration will need to be post-calibrated.
Note: If you have the silver mapping processor that resides behind
the operator’s seat in the combine, verify that you are running yield
mapping firmware version 5.6 or higher.
Note: If you have the brown mobile processor that resides behind
the GreenStar Display in the combine, verify that you are running
yield mapping firmware version 6.33 or higher.
Calibrate by Harvest Date
If you calibrate by harvest dates, the Calibration window will list the data files
that were recorded in the combine for that field. The files will be divided by
machine and serial number, and the date and time that the crop was harvested
will be listed next to each file.
The weight calibration can be done in one of two possible ways (by the
calibration factor or by the percentage); the moisture can be calibrated at the
same time. Complete both areas prior to selecting the OK button.
If you are harvesting during the time when your area of the country changes
between standard and daylight savings time, you will have to reset the time on
your GreenStar Display in the combine.
Calibrate by harvest date:
1. From the field map that needs to be calibrated, click Layers .
2. Select Edit for the yield or moisture point layer.
3. From the Tools menu, select Field>Combine Calibration>by harvest
date.
4. In the Calibration window, check the boxes for those files that have a time
