Wind Direction Offset
If the transmitter cannot be aligned so that the arrow on the bottom
points north, make a wind direction offset. Configure the deviation
angle in the transmitter.
1. Mount the transmitter to a desired position. See Mounting on page
42.
2. Define the deviation angle from the north-zero alignment. Use the
± sign indication to express the direction from the north line.

3. Enter the deviation angle in the device using the wind message
formatting command aWU,D (direction offset). See Checking the
Settings (aWU) on page 127.
Now the transmitter transmits the wind direction data by using the
changed zero-alignment.
