PF3000 Pro Cotton Yield Monitor
Calibrating Seed Cotton Weight Ag Leader Technology
July 2003 3-10
Step Action
8 The screen above allows you to include a load in the calibration or
exclude it by “unchecking” it and turning it off.
9 Press the PERFORM CAL key to start the calibration. The monitor
will start calibrating and then it will stop and display "Full
Calibration Complete".
NOTE: The calibration error is the percent difference between the
actual weight and the estimated weight. The maximum error is the
error of the calibration load that has the highest error.
Example:
Actual weight: 10,000 Lbs.
Estimated weight: 10,100 Lbs.
Error: + 1 %
10 Good Calibration Results:
If you have three or more calibration loads, your goal after
completing a calibration should be to achieve an average error of
less than 5 percent and a maximum error of 10 percent
If you have at least three calibration loads, and you find a load with a
high calibration error after completing the calibration, you should
remove the load as a calibration load by pressing the CAL ON/OFF
key. Press the PERFORM CAL key again to restart the calibration.
Once you are satisfied with your calibration results, press the EXIT
key until you return to the main operating screen.
Reasons for high calibration errors on loads
•
Cotton calibration set is incorrectly set for the load
•
Cotton moisture or density is considerably different between loads.
•
Actual pounds value is not correct
•
Cotton weighed is not the same amount of cotton that was harvested into
the load (for example: picker basket was not empty before starting the
load or forgot to change loads in the monitor and added more cotton into
the load (in the monitor) after cotton weighed or cotton spilled onto the
ground)
•
Installation problem with flow sensor
