4.21 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. Choosing this item will allow
you to calibrate the ground speed sensor to a known
distance. The default distance is 400 feet (122
meters) but this can be set by the user. To perform a
ground speed calibration, determine the distance to
be used and measure out a course.
Procedure:
1. To complete the calibration, measure a course 400
feet (122 meters) 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 the procedure.
2. On the monitor, verify that the calibration length is
400 feet (122 meters). If not, please change so that it
reads 400 feet (122 meters).
3. Once 400 feet (122 meters) is selected, highlight and select Continue.
4. The monitor now displays “Start Driving” and
shows a Wheel Pulses Received window. Notice this
number increase while driving the 400 foot (122
meter) course.
5. Once at the end of the 400 foot (122 meter)
course, stop the tractor, highlight the complete
button and press Enter.
6. Ground Speed is now calibrated.
