Width Correction Calibration - Raven SC1 Calibration And Operation Manual

CHAPTER 5

WIDTH CORRECTION CALIBRATION

Ideally, the correction for the first body should be the same on both the right and the left side. When the system is
still not accurate enough, the automatic calibration may be used to correct for errors.
NOTE: The following steps must be performed in actual field conditions. During performance monitoring,
the tractor should be in the furrow. Complete a pass driving manually in both directions before
starting the automatic calibration.
Complete the following steps for best results with the automatic width calibration:
1. Reset the Online and Line-Acquire Performance statistics. Refer to the Performance Monitor section on page 68
for assistance with resetting the performance statistics.
NOTE: It is important to clear previous performance data to ensure previous steering characteristics do not
negatively influence the auto calibration.
For best results, use the longest swaths available in the field for calibration and tuning of the plough
steering system.
2. Create a straight (A-B) guidance line.
3. While steering manually, begin ploughing the first 20 m [65 ft] of the swath.
4. Engage the steering system on the guidance line and allow the system to steer until approximately 20 m [65 ft]
from the end of the swath.
5. Disengage the steering system and manually steer to the end of the swath.
6. Repeat step 3 through step 5 until the steering system has been engaged through approximately 500 m [1640
ft] with the plough in the ground and at least one pass in each direction.
7. After approximately 500 m of active plough steering, select the Tools Menu button followed by the Steering
Setup tab and the Width Correction Calibration button.

8. Select the Automatic Calibration button. The system will use the recorded performance statistics to calculate
the offset values.
