Aligning the WXT510
To help the alignment, there is an arrow and the text
North
on the
bottom of the transmitter. WXT510 should be aligned in such a way
that this arrow points to the north.
Wind direction can be referred either the true north, which uses the
earth's geographic meridians, or to the magnetic north, which is read
with a magnetic compass. The magnetic declination is the difference
in degrees between the true north and magnetic north.

Sketch of Magnetic Declination
NOTE
The source for the magnetic declination must be current as the
declination changes over time.
Compass Alignment
To align Weather Transmitter WXT510, proceed as follows:
1.
If the WXT510 is already mounted, loosen the fixing screw on the
bottom of the transmitter so that you can rotate the device.
2.
Use a compass to determine that the transducer heads of WXT510
are exactly in line with the compass and that the arrow on the
bottom of WXT510 points to the north.
