Step 01: Crank Revolutions Required for Calibration New Product Calibration Steps
Once your "X-Sprocket" is installed and you have loaded your hopper you need to prepare you meters for calibration. 1. Set the gearbox to Low Ratio, Range B, Speed No. 8. At this setting the gearbox input to output, ratio is 1:1
If you know the specific product you're using the meter roll you have follow the web link below. 2. Turn the crank the number of turns indicated in the chart at the beginning of this chapter. "See Step 02"
To create a custom Product Flow Rate Chart continue to "New Product Calibration Steps". Go to Implement Working Width Calculator

4. Record this weight on the blank Product Flow Rate Charts on the next two pages in the Calibration
Weight column.
5. Multiply this calibration weight by the Gearbox Adjustment Factors listed on the chart in order to calculate the actual application rate in pounds per acre for all other gearbox settings.
calculate the actual application rate in pounds per acre for all the other gearbox settings.
