For example, you can set the wind speed output 1 ... 5 mA which corresponds to speed values
0 ... 51.2 m/s and to direction values 0 ... 540 degrees. This range does not change the scaling
of 360 degrees corresponding to one full turn, rather it allows to calculate the average
direction during northerly winds. These settings are carried out by the jumpers as shown in the
following table.
