Calibration menu settings (Values are displayed either in

metric or imperial units, depending on which one has

been selected in the basic settings menu).

To choose the seed disc and settings for the

metering unit, refer to the chapter Drilling

recommendations in the machine manual.

G. Set the required percentage increase/decrease rate in

feed volume in the feed rate field. If you select, for

example, 5%, the feed rate will change in increments

of 5% every time the button is pressed in the

operations menu.

H. If the expected driving speed is, for example, 12 km/

h, the calibration must be done for a speed of 12 km/h.

I. Select which of the row units is to be calibrated (i.e.

the row with the calibration bag). If the calibration is

to cover all row units, select ON (default setting).

If calibration is to be carried out individually for only

one row unit, select OFF.

J. Enter the number of holes on the seed disc installed

in the metering unit.

K. Select the required calibration method. Enter the

spacing between plants in the upper row or the

number of seeds in the lower row. (The selected

calibration method is shown in the operations menu.)

L. Calibrate

Calibration

Figure 7.3

The calibration is normally carried out on one seed feed

housing unit and the values are automatically carried

over to the others. If desired, it is also possible to

calibrate each seed meter individually.

•

Check that there is seed in the seed hopper; the depth

of seed should be at least 15 cm.

1. Place a calibration bag under the output for the seed

meter to be calibrated.

2. Start the fan, the value is shown in field (A) see

"Figure 7.2 ". Check that there is the right amount of

air pressure (3.5 kPa) in the seed metering unit.

3. Enter the values in the calibration menu.

4. Start the calibration using the (L) button, refer to

"Figure 7.2 " and hold it in until the indication for

the amount of seed fed out is showing at least 200.

5. Read off the proportion of skips

. If any value is too high, adjust the singulator.

•

To reduce the proportion of doubles, reduce the

singulator dial's set value.

•

To reduce the proportion of skips, increase the

singulator dial's set value.

Repeat points 4 to 5 until the required accuracy

has been achieved.

6. You can exit the calibration menu using

directly to calibration of another unit.

7. Remove the calibration bag and pour the seed back

into the hopper.
