2. The value "Imp./100m" is not known
-
Measure accurately a calibration distance of 100
m in the field. Mark the start- and ending point of
the calibration distance.
-
Bring the vehicle into starting position and the
seed drill into working position (perhaps interupt
the seed metering).
-
Press key
and hold it by simultaneously
pressing key
, the figure 1800 will appear.
-
Drive accurately along the calibration distance
from the starting- to the end point (when starting
to move, the counter returns to "1") . Hereby the
display shows the continuously determined
impuses.
I
During the calibration run do not press
any key..
Display during the calibration test
-
Stop after 100m. On the display now the number
of impulses (e. g. 1005) is shown which had been
determined while travelling the calibration distance
Auf (100m).
-
Press key
and this way store the displayed,
determined calibration figure (Imp./100m).
-
Press key
once again and check the stored
calibration figure. The display should now show
the determined calibration figure. e. g. 1005
Imp./100m.
Display of the determined calibration figure
-
Enter the determined calibration figure into table
3.

If the calibration figure has been
determined by travelling a calibration
distance, definitely convert accordingly
the necessary numbers of crank turns
mentioned in table 2.
