Calibration

  1. Figure 2.

  1. Set the feed units and select a feed roller so that it suits the actual fertiliser type.

  2. Enter the values in the calibration menu.

  3. Fill the feed system using the button.

  4. Empty the calibration bag and put it back in place.

  5. Select the calibration button and hold this button in until the right amount of fertiliser has been fed into the calibration bag. The pulses from the feed are displayed alongside the pulse symbol.

  6. Weigh the contents of the calibration bag. Tip: First reset the scales with an empty calibration bag.

  7. Enter the weight of the contents of the calibration bag in field (E) in the calibration menu. The number of pulses per kg will be automatically displayed in field (F).

    To enter the number of pulses manually, press field (F) and specify the number of pulses in the pop-up window. To cancel the calibration and perform a fresh calibration, repeat points 3 to 7.

  8. You can exit the calibration menu using , or go directly to calibration of another unit.

  9. Reset the calibration flaps to position B for drilling.

Figure 3.

  • Before drilling, ensure that the same type of feed roller is fitted to all feed units.

  • Perform a new feed check in the field after drilling about a hectare.

Check regularly that deposits have not built up on the seed rollers and in the feed units.
