Test in progress!
Calibration test in progress: After starting, the seeding shaft begins rotating
automatically without the fan motor. The seeding shaft stops automatically
after the set time. If a calibration button is installed, the test is only stopped
once it is pressed.
Entry of the calibration
test:
Now weigh the calibrated seed quantity (deduct the weight of the collection
bucket or the calibration bag) and enter the weight. Confirm with OK.
To really spread the desired spread rate, we recommend repeating the calibration test until the message
"Test not precise! Repeat?“ no longer appears. If "Seeding shaft speed too high" appears on the display,
the seeding shaft is not able to rotate fast enough. If "Seeding shaft speed too low" appears, the seeding
shaft is not able to rotate slowly enough. To fix this error, you can replace the seeding shaft with a larger
or smaller seeding shaft (see also chapter 6.1 Notes).
With the OK button, you can return to the previously displayed value. Only when the automatic
readjustment of the seeding shaft is under 3 % (difference), the "checkmark symbol" and the spread
quantity in kg/ha will appear on the main screen.
Entry of the
Calibration test:

The seeding shaft speed is now automatically correctly calculated. Then
the display goes back to the Main menu.
Now the set kg/ha
appears on the
display.
The two-column display appears when working with a
speed sensor.

If a fill level sensor is installed on your PS/MD/UDW/LF, and the message "Hopper almost empty" appears
on the display during the calibration test, the test will continue running. If there is not enough seed in the
hopper, however, this can falsify the precision of the calibration test.
Seeding shaft - manual
This menu point is used for rough presetting of the seeding shaft speed. The
speed (%) of the seeding shaft does not need to be changed, because the
settings are automatically adopted from the calibration test.
5.1.2 CALIBRATING IN GRAINS/M²
This option for the calibration test is available in the PS/MDG/MDP operating modes, not for MDD.
