Checking Data Accuracy PFadvantage
End of Season Ag Leader Technology
September 2003 4-48
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 the GPS receiver and memory cards, print the season
summary using mapping software that will read yld files from the
memory card.
• 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 turn off the loads as
calibration loads by pressing the CAL ON/OFF key.
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 Menu Key, CAL, WEIGHT, select the grain type and press
SHOW CAL LOADS.
2 On the Grain Calibration screen for the selected grain type press
PERFORM CAL.
