Notes
Align U axis with
transducer axis
X1
X1. Aligns U axis with North/South axis.
Align U axis +45
to transducer axis
X2
X2. This re-aligns both U&V and polarity 45˚ to
transducer axis.
Reverses Polar
Direction
X3
X3 reverses reported polar direction to allow the
instrument to be mounted upside down. N.B.
Does NOT affect UV alignment (Mode 1, 3).
Align @ 45° from
North
X4
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.
