Before You Begin
After the harvest season ends, remove the monitor from the picker cab. Use
the provided 110-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 SMS.
•
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 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 10% or higher. Most loads should be less than 8%.
•
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 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 cotton type and
press SHOW CAL LOADS.
2 On the Calibration screen for the selected cotton type press
PERFORM CAL.
3 When the monitor completes its full calibration, press EXIT to scroll
through each calibration load and its calibration error to look for
high errors.
