Wind Direction Correction
Make a wind direction correction in case WXT510 cannot be aligned in
such a way that the arrow on the bottom points to the north. In this case,
the deviation angle from the true north should be given to WXT510.
1.
Mount the transmitter to a desired position, see section
Mounting
on page 29
.
2.
Define the deviation angle from the north-zero-alignment. Use the
± sign indication to express the direction from the north line (see
example pictures).
3.
Feed the deviation angle to the device by using the wind message
formatting command aWU,D (direction correction), see section
Checking the Settings on page 93
.
4.
From now on, WXT510 transmits the wind direction data by using
the changed zero-alignment.
