Speed Calibration
In order to fine-tune the default speed calculation or to
convert to radar speed signal, the controller may be
calibrated as follows:
1. Set two flags 400ft apart (100 meters if in metric
mode).
2. To calibrate the Controller for speed, press the
FUNCTION button until the screen at right appears.
3. Press the
Up arrow button to initiate new speed
calibration routine.
Press the
Down arrow button to restore factory
default setting.
4. This is the first window that appears in Speed
Calibration mode. Press FUNCTION button to
accept, or
button to change units of measure.
ENGLISH (U.S. Customary) speed units are:
mph (miles per hour)
METRIC speed units are:
kph (kilometers per hour)
If you change units of measure for speed calibration,
it also changes units for seed rate. Numeric values
entered or previously computed are not converted.
Be sure to review all screens before planting.
