Kestrel® 2000 Pocket Weather® Meter 7
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.
