4.5 Calibrate speed sensor (Wheel or Radar)
Calibrate Wheel speed
In Screen 12 there is the calibration of the driving speed.
In order to calculate the driving speed, the system must know how
many impulses the speed sensor emits per metre of driven
distance. The number of impulses depends on the rotations of the
wheel and the number of pulses per revolution.
The upper value corresponds to the number of impulses matching
the lower value, the measured distance
TIP: if the number of pulses is more then 1000/100m you can
reduce the distance till the number is below 1000

for example
not 5000/100m but 500/10m
If the impulse values for a certain measurement distance is
already known, the two values, measurement distance and
matching number of impulses, can be input directly (e.g. change
of tractors in joint use of machines).
If the driving speed has to be calibrated, please proceed as
follows:
• A measurement distance, for example 100 metres, is precisely
set.
• At the start of the measurement distance, press arrow key ,
the calibration process is started, a signal sounds.
• Run along the measurement distance and press the OK key at
the end, the measurement distance flashes.
• Confirm the measurement distance with the OK key.
If the measurement distance set does not correspond to the lower
value in the display, change the value in the display accordingly.
Note: The calibration run should be done on a field with the
spray tank half full. In this way, errors by slip, subsiding
wheels etc. are reduced to a minimum.
