12. Push the calibration crank handle (Fig.
128/1) onto the star wheel (Fig. 128/2).
13. Turn the star wheel with the calibration
crank handle counterclockwise until all
chambers of the metering rollers are filled
with seed and a uniform seed stream flows
into the calibration troughs.
14. Empty the calibration trough and push it
back under the metering unit.
15. Turn the star wheel anticlockwise the
number of crank turns specified in the table
(Fig. 129).

The number of crank turns on the star wheel depends on
the seed drill working width (1).
The number of wheel revolutions (2) relates to an area of
1/20 ha (500 m
2
) or
1/10 ha (1000 m
2
).
The usual area for the calibration test is 1/40 ha. With
extremely small seeding rates, e.g. with rape, it is
advisable to perform the calibration test for 1/10 ha.
Example
Working width: ........................... 12.0 m
Number of crank turns
on 1/20 ha: ................................. 19.0
