Calculating the Calibration Values
Granular Applications
Boom Cal
To calibrate section widths in inches [cm] for the granular application types:
•
For single section control systems, enter the total spread width as the boom 1 cal.
•
For dual section control systems, enter the left side spread pattern as boom 1 cal and the right side spread
pattern as boom 2 cal.
Spreader Constant
Note:
The spreader constant should be verified by performing the procedure in Verification of Spreader
Constant section on page 200.
For Gran 2 or Gran 3 applications, gate width is the total of both openings.
Standard Rate display
For Rates displayed in 1 pound increments, the formula to calculate the spreader constant is:
Where SC = the Spreader Constant, L = Length of belt travel in inches per 1 revolution of the encoder, GH =
Gate Height in inches, GW = Gate Width in inches.
For Example:
Given a Length of belt travel of 13 inches, a Gate Height of 7 inches and a Gate Width of 15 inches:
Enter 228 as the Spreader Constant if the field computer is set to display English units.
Metric Rate Display
For Rates displayed in 1 kg increments, the formula to calculate the spreader constant is:
Where SC = the Spreader Constant, L = Length of belt travel in centimeters per 1 revolution of the encoder, GH
= Gate Height in centimeters and GW = Gate Width in centimeters.
For Example:
Given a Length of belt travel of 33 cm, a Gate Height of 18 cm and a Gate Width of 38 cm:
Enter 797 as the Spreader Constant if the field computer is set to display Metric units.
