Angle Sensor Calibration
The AccuGrade System uses the angle sensor in order to measure blade pitch. The angle sensor is also used in the valve calibration.The calibration procedure sets the current pitch reading to zero. The angle sensor is located on the back of the blade.Note: Before you attempt to calibrate the angle sensor, make sure that you park the machine on a level surface. Place the machine in the position that was used for the measure up.Use the "Setup Menu - Installation" dialog in order to enter machine settings into the AccuGrade System.
