Manual calibration
If the pulses per 100 metres for the respective sensor are known, this value can be
directly entered under the calibration value symbol.

Automatic calibration
With automatic calibration, the calibration value is determined automatically while driving a distance of
100 metres.
The procedure is as follows:
1. A straight distance of 100 metres is measured. The beginning and end of this
distance are marked.
2. The tractor is positioned precisely at the beginning mark, e.g. front axle exactly
over the mark.
3. The Tractor settings menu is selected.
4. The 100 m Start button is pressed and held for 2 seconds.
5. As soon as the message "Drive 100 m, then press 100 m STOP" appears, start
driving. The controller now counts the pulses coming from the sensor.
6. Drive the tractor to the end mark, e.g. once more precisely with the front axle over
the mark.
7. As soon as the tractor comes to a stop, the 100 m Stop button is pressed and held
for 2 seconds.
If the calibration was successful, the message "Calibration successful, value
accepted" will be displayed. The calibration value is now saved.
If the calibration was not successful, the message "Calibration invalid, original
value restored" is shown and the original value is set (see Point 7 for possible
causes of error).
8. The calibration must be tested by driving the tractor over a distance and comparing
the speed displayed on the Control Box with that of the tractor.
If the speeds do not match, the calibration test must be repeated.

6.3.5 PRE-METERING MENU
In this menu, you can enter the settings for pre-metering. For pre-metering, as soon as a speed of 0.1
km/h or faster is driven, the set speed is used to regulate the seeding shaft. This allows you to avoid gaps
in the seeded area (e.g. at the beginning of the field or when standing still on the field).
