Replacing the Impeller
You may recalibrate the wind speed readings by replacing
the impeller. Press FIRMLY on the sides of the black
impeller housing with your thumbs to remove the entire
assembly. When inserting the new impeller, be sure the
arrow is facing the display side of the unit, and is aligned
with the top of the meter. Press on the sides of the housing
rather than the center.
BEAUFORT SCALE
The Beaufort Scale is a system for estimating
wind force without the use of instruments based
on the visible effects of the wind on the physical
environment. The behavior of smoke, waves, trees,
etc., is rated on a 13 point scale. The scale was devised
in 1805 by the British naval Commander Sir Francis
Beaufort (1774-1857) and is still commonly used
by mariners.
