  1. Calculates the number of pulses.

Calibration menu settings (Values are displayed either in metric or imperial units, depending on which one has been selected in the general settings menu).

  1. Select which of the feed units is to be calibrated (i.e. a row with a calibration bag). The position of the feed units is the same as that of the row unit.

    If the calibration is to cover all feed units, select ON (default setting). If the calibration is to be done individually for only one row unit, select A.

  2. Enter the required micro-granulate application rate.

  3. Enter the weight of the calibration bag contents.

  4. Calculates pulses/kg. (You can also enter pulses/kg manually by pressing the row and entering the value in the pop-up window.)

  5. Calibrate

  6. Feed for filling the feed system.

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 output 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 calibration bag contents in field (D) in the calibration menu. The number of pulses per kg will automatically be displayed in field (E).

    To enter the number of pulses manually, press field (E) and key in the number 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.

  • 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.
