Calibrating Radar Sensor (Optional)

NOTE: If radar unit is removed from machine install dust cap on wiring harness for environmental protection.

When radar unit is left on machine but not used, dust cap must be installed on wiring harness and dust cap (with seals installed in end) placed on radar unit wiring connector.

Radar sensor overrides wheel speed sensor when radar sensor is installed and vehicle speed is between 3 and 20 mph. Radar is not available below 2 mph and in fourth range.

GPS speed may override Radar speed sensor when GPS Speed has been selected. If using GPS speed, select Radar Speed prior to calibration.

1. Fill the solution tank half full of water or solution.

2. Measure a 122 m (400 ft.) course with tape measure on flat terrain that is most typical of field conditions (loose, medium, hard-packed). Do not use end rows due to possible varying ground conditions that can affect calibration.

3. Mark both beginning and end of course with markers that are visible from cab.

4. Allow enough room at each end of course for sprayer to travel entire course without speeding up or slowing down.

   C - Input Box

   D - Enter Button

   Follow instructions on first screen. Start driving somewhere before beginning of the course and reach speed recommended on screen. While maintaining that speed, press “Enter” button (A) to turn wheel counter “ON” when the sprayer reaches the beginning of the course.

9. Keep constant speed over the course, and when sprayer reaches the end marker, press “Enter” button (B)” to turn counter “OFF”.

10. Record calibration value that appears.

11. Repeat calibration two more times and record calibration values.

12. Average the three calibration values.

13. Select input box (C) next to “Radar Speed Calibration Value”. Enter calibration average.

14. Press “Enter” button (D) to save entered value and return to the vehicle Calibration Tab.

15. To verify calibration value, measure the course with the distance counter. (See Operating Distance Counter in this section.)

16. If the “Distance” is anything more or less than 120—123 m (395—405 ft.), refine the previous wheel calibration number as follows:

    Wheel Calibration Number x Recorded distance ÷ by 122 m (400 ft.) = New Wheel Calibration Number

17. Enter new radar calibration number.

    Calibration value ranges:

    33.0—37.0
