Spreader calibration
To calibrate a spreader, first calibrate the implement lift switch. Then calibrate the modules to
ensure your system performs at the level you require.
1. Implement lift switch calibration
2. At the Field-IQ Calibration screen, select the Implement Lift option.
3. Raise the implement and then tap Next.
4. Lower the implement and then tap Next.
5. Tap OK to return to the Field-IQ Calibration screen.
Rawson modules calibration
The Field-IQ system Calibrate option only displays on the Configuration screen if you have at least
one Field-IQ system Rawson control module or rate control module set up to control the rate.
Note – If you have an implement lift switch, calibrate it first.
1.
At the Configuration screen, select Field-IQ and then tap Calibrate.
2. At the Field-IQ Calibration screen, select the module you want to calibrate.
3.
Select the first module to calibrate. The Planter Calibration screen displays.
Note – If a Rawson module was configured, the correct calibration is selected automatically.
Setting Explanation
Gear Ratio Specifies the actual ratio from the application rate sensor to
the seed meter shaft RPM. This is the number of
revolutions the application rate sensor turns for each
revolution of the seed meter.
Gear Ratio Calculator Use the calculator to determine your gear ratio.
Calibration Constant A calculated value that the system determines during
calibration. This field allows you to adjust for
inconsistencies in the seed meters. To start out, leave the
value at 1.000. After the calibration test, the system may
