A. Calculates the number of pulses.
Calibration menu settings (Values are displayed either in
metric or imperial units, depending on which one has
been selected in the basic settings menu).
B. Select which of the output units is to be calibrated (i.e.
a row with a calibration bag).
The position of the output units is the same as that of
the row unit.
If the calibration is to cover all output units, select
ON (default setting). If calibration is to be carried out
individually for only one row unit, select OFF.
C. Enter the required micro-granulate feed rate.
D. Enter the weight of the calibration bag contents.
E. Calculates pulses/kg. (You can also enter pulses/kg
manually by pressing the row and entering the value
in the pop-up window.)
F. Output for filling the output system.
G. Calibrate
Calibration
Figure 7.8
The calibration is normally carried out on one output unit
and the values are automatically carried over to the
others. If desired, it is also possible to calibrate single
output units individually.
Before calibration, check that there is a sufficient
amount of micro-granulate in the micro-granulate
hopper. There should be micro-granulate to a minimum
depth of 15 cm in the hopper.
1. Set the output units and select a output roller so that it
suits the actual micro-granulate type.
2. Enter the values in the calibration menu.
3. Fill the output system using the (F) button.
4. Empty the calibration bag and put it back in place.
5. Select the calibration button (G) and hold it in until
the right amount of micro-granulate has been fed into
the calibration bag. The pulses from the output are
displayed alongside the pulse symbol.
6. Weigh the contents of the calibration bag. Tip: First
reset the scales with an empty calibration bag.
7. Enter the weight of the calibration bag contents in
field (D) in the calibration menu. The number of
pulses per kg will be automatically displayed in field
(F). To enter the number of pulses manually, press
field (E) and enter the number of pulses in the pop-up
window. To cancel the calibration and perform a
fresh calibration, repeat points 3 to 7.
The calibration result becomes the baseline
value. Always check the actual feed rate on
the field. If necessary correct the pulses/kg.
Example: If the feed rate is actually 10% too
little, increase the pulses/kg by 10%. Note
the fertiliser pulses/kg and the actual feed
rate for future use.
8. Exit the calibration menu using
, or go directly
to calibration of another unit.
9. Reset the calibration flaps to position B for sowing.

•
Before drilling, ensure that the same type of output
roller is fitted to all output units.
•
Perform a new output check in the field after drilling
about a hectare.
•
Regularly check that deposits have not built up on the
feed rollers and in the output units.
