For example, you can set the wind speed output from 1 to
5 mA which corresponds to speed values from 0 to 51.2 m/s
and to direction values from 0 to 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 of the WAT12 transmitter as described
in Table 3 below.
