calibration method).
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. Set the speed for which the machine is to be
calibrated. 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
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
. Check that there is the right amount
of air pressure (3.5 kPa) in the seed feed housing.
3. Enter the values in the calibration menu.
4. Start the calibration with the
button and hold it in
until the indication for amount of seed fed out is
showing at least 200.
5. Read off the proportion of skips
and doubles
. 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
, or go
directly to calibration of another unit.
7. Remove the calibration bag and pour the seed back
into the hopper.
