Before You Begin After harvest season ends, remove the monitor from the combine cab. Use
the provided 12-volt power supply to turn on the monitor in your house or
shop and check the recorded yield data for errors. Options for checking the
data follow:
•
If you are using a GPS receiver and memory cards, print the season
summary using Precision Map 2000.
•
If you do not have a GPS receiver, connect the monitor to a computer
and print the field/load summary as instructed in the Printing Field/Load
Summary document in this section.
•
If you cannot print a summary, follow the instructions on these pages
and use the monitor to check your data for accuracy.
Calibration Any load for which you see an error listed in the % Err column of the
summary is a calibration load. Check the following:
•
Actual weight and grain type of each calibration load, ensuring that the
loads are set correctly
•
Load with a large error in the % Err column, which is any load with an
error 5% or higher. Most loads should be 1% to 4% error.
•
Loads with unusually large errors may need to have the actual lbs value
removed (by incrementing it to zero)
Refer to the Grain Weight document in the Calibration section for
instructions on examining and correcting any errors.
If you do not have a summary print out, follow these steps to check the
calibration errors on the monitor:
Step Action
1 Press the GRAIN key until “CAL LBS NOW?” appears on the
display.
2 Press the YES key.
