3. Enter the desired dose per hectare on the electronic console
4. Start the metering unit
5. Start the calibration test procedure on the electronic console by pressing the button on the seeder

Caution, the button must be held pressed during filling; do not release the button until the container is
filled.
The more seeds are introduced into the container, the greater the precision of the calibration test.
6. Weigh the seeds collected in the container.
7. Insert the weight of the seeds into the electronic console.
8. Repeat this step 3 times to get a precise calibration
In the version with a mechanical drive from the star wheel, the calibration test should be carried out with the
help of the drive wheel. At a working width of 3 m, the wheel performs 1360 revolutions per hectare. During
the test, we make the rotation of the wheel per 1 are of the sown dose, that is, 13.6 revolutions; weigh the
sown dose and multiply it by 100, which gives the dose in kg/ha.
NOTE!
The data included in the seeding chart should be regarded as indicative, since the seeds of the same species, but
different varieties, are not the same in size and weight.
In order to obtain the exact desired sowing rate per hectare, perform the sowing test
