If the transmitter cannot be aligned so
that the arrow on the bottom points North, make a wind direction offset by configuring the
deviation angle in the transmitter.
Mount the transmitter to a desired position.
Define the deviation angle from the North (zero) alignment. Use the ± sign indication
to express the direction from the North line.
Enter the deviation angle in the device using the wind message formatting command
aWU,D (direction offset).
Now the transmitter transmits the wind
direction data using the changed zero alignment.
