Xx - 45 Alignment Offset/Inverted Operation
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).
Figure 4 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.
