X1. Aligns U axis with North/South axis.
aligns both U&V and polarity 45
X3 reverses reported polar direction to allow the
instrument to be mounted upside down. N.B.
Does NOT affect UV alignment (Mode 1, 3).
X4 set polar alignment at 45 degrees from North
when instrument is mounted upside down.
Does NOT affect UV alignment (Mode 1, 3).
The figure below shows the polarity of U and V if the wind components along the U and
V axis are blowing in the direction of the respective arrows.
