Near Intersection of I-35 & I-90 Southern Mn. | Beware that if you change the Wheel Speed Cal at this time, that prior harvesting will be affected. In your case this would probably be good.
A Lazy "quick and dirty" method would be to adjust the Wheel Cal until the indicated speed on the PF300 agrees with the combine speedometer (assuming it is correct).
Another way is to drive the combine at a constant speed in good conditions and attempt to make the indicated Wheel speed on the PF3000 agree with the indicated speed on the GPS.
There is no Cal for GPS since the GPS is delivering the supposed correct speed directly and no adjustment is needed.
