The third step in the custom rudder angle sender calibration process is to turn the wheel hard over to port, and to measure the angle or the rudder (angle from center) with a protractor or other instrument. Use the Increase and Decrease keys until the highlighted rudder angle value is at the measured value, and then press Enter to accept the value and store it within the RAA100. Figure 148 shows a screenshot of the starboard rudder calibration screen. You may also press the Abort Key ( ) to end the calibration process.
