After having carried out the calibration test put the troughs back in
place.
•
Pull the supporter backward
•
Place the hooks of the calibration test trough under the supporter of the cones
•
Turn up the calibration test trough by using the hooks of the troughs as hinges.
While turning, the supporter is to be in its rearmost position
•
Push the upper edge of the trough under the springs. The springs lock the trough
and keep the cones in place.
Keep the crank in a safe place, e.g. on the screen.

Field test
A field test is the most accurate testing format of feeding amount. Very accurate results
can be achieved if the field test is carried out on the field which is to be sown and in
conditions equivalent to sowing. Field test can be done only for seed.
Carrying out the field test:
•
Adjust the equipment according to the calibration guidelines (section 4.4).
•
Measure a distance to the field corresponding to one are sown area, which
based on machine type is:
- KL 2500 - 40 m
- KL 3000 - 33,3 m
•
Put calibration throughs under sowing chambers as in figure 12.
•
Drive outside the test distance, about 10 meters, with the machine in working
position so that each sowing chamber is feeding out the seeds.
•
Empty the contents of calibration throughs.
•
Drive a distance in accordance with the table above; the machine lowered to the
sowing position with a normal sowing speed. Seeds will fall to the calibration
throughs.
•
Weigh the seeds in calibration throughs and multiply the weighing results with
100 to get the resulting seed amount in kg/ha.
•
If adjustments are needed, carry these out according to the calibration
instructions.
HINT:
If you can calculate how many rotations wheel rotate in test distance (40 m or 33,3
m) in that conditions, you can use that value also for calibrating fertilizer.
NOTE:
If conditions change from the conditions field test was made, the seeding accuracy
may change also.
