15. If the calibration sample is more than a few percent
different than the desired FieldRate, pick a new chart
rate based on the difference factor.
16. Find the chart rate closest to NewChart. Change the
Final Drive sprocket and Drive Type as needed. If the
correction went off the Standard chart to the low
side, consider installing the Rate Reduction kit.
17. You may want to repeat calibration procedure at the
new setting if your results varied greatly from the
Seed Rate Chart.
