6.4 Calibration test
Switch off the seeding shaft motor and the blower fan motor.
The blower fan cannot be switched on during calibration.
1. Prepare the implement for the calibration test (see section 5.6, page 46).
2. Check that the correct seed metering wheels have been fitted.
3. Fill the seed hopper (see section 5.5, page 45).
4. Adjust the brush for the seed type (see section 4.1.3, page 35).
5. Determine the seeding shaft speed (see section 6.3, page 53).
6. Switch on the control terminal (see section 6.2.1, page 52).
7. Enter the determined seeding shaft speed (e.g. 50 [%]) on the control terminal using the
button.
8. Start the calibration test:
Press the
button, hold, and press the button
The seeding shaft rotates for precisely one minute.
9. Weigh the seed quantity collected during calibration and compare with the required seed quanti-
ty.
Example:
Required spread rate: 1.62 kg/min.
Actual spread rate: 1.46 kg/min. (at a seeding shaft speed of 50%).
The actual spread rate is 10% lower than the desired spread rate.
Increase the seeding shaft speed by 10% to 55%.
10. Repeat the calibration test until the desired spread rate is achieved.
The calibration test can be terminated early by pressing one
of the buttons
