7.3.4 GROUND SPEED CALIBRATION
All new systems require a ground speed calibration
to ensure accurate area totals and accurate
ground speed readings.
Note: During the calibration the monitor is counting
the number of pulses produced from the drill
mounted sensor. The monitor will display the
pulses counted in 400 feet.
Procedure:
1. To complete the calibration, measure a course
400 feet long preferably on level ground with a
start and finish point. Line up Tractor at the
Start Point. The drill must be in the down
position throughout this procedure.
2. On the monitor, verify that the calibration
length is 400 feet. If it is not, please change so
that it reads 400 feet.
3. Once 400 feet is selected, highlight and select
Continue.
4. The monitor now displays “Start Driving” and
shows a Wheel Pulses Received window. You
should see this number increase as you drive
the 400 foot course.
5. Once at the end of the 400 foot course, stop
the tractor, highlight the complete button and
press Enter.
6. Your Ground Speed is now calibrated.
7.3.5 METER CALIBRATION
NOTE
: All Meters on a machine must be
individually calibrated. Calibrations
must be done each time a crop is
changed. Meter Calibration is a
procedure that allows for accurately
setting the individual meters to
apply the desired rate of material.
Before a meter calibration can be
done the implement width must be
entered and the speed calibration
must be completed (See Sections
and 7.3.4).
