Calibration —Speed
In order for the Precision Rate Controller to meter the proper amount of material,
it must have an accurate field speed input. Speed may be supplied by radar or
by wheel pickup sensor. For the Controller to convert the pulses that it is
receiving from the speed input into accurate speed, it must be calibrated. To
calibrate the Controller for speed, press the Function key until the screen
appears, as shown in Figure 22:

Figure 23. Press up to initiate new speed calibration routine; press down to
restore factory default settings.
Set two flags 400’ apart (100 meters if in metric mode). Begin driving at a normal
field speed; when the tractor passes the first flag, press engage (Figure 24). The
display will show the distance traveled. (Figure 25)
