Spreading operation169BAXIS 50.2B.6 CalibrationFor precise control of the discharge amount, we recommend running a new cali-bration test every time you change fertiliser material types.Carry out calibration: Before spreading for the first time. If the fertiliser quality has changed significantly (moisture, high dust content,cracked grain). If a new fertiliser type is used.The calibration must be conducted with engaged PTO at a standstill or duringtravel over a test track.B.6.1 Determining the nominal output quantityCalculate the nominal output quantity before starting the calibration test.Calculating the exact forward speedThe exact forward speed must be known to calculate the nominal output volume.1. With a semi-filled machine, drive a distance of 100 m on the field.2. Stop the time required for this.3. The exact forward speed is indicated at the scale of the calibration test calcu-lator.Figure 8: Scale for calculating the exact forward speedNOTICEExecute the calibration test at the operating unit for machine version W.The calibration test is described in a separate operator’s manual for the operat-ing unit. This operator’s manual is an integral part of the operating unit.NOTICEThe machine version W is equipped with an electronic drop point adjustment.The control unit automatically sets the machine to the drop point according to thecalibration test position (scale value 0).KDRCQW
