Background material states that excessive error of an anemometer is more than 2% error. Is this 2% error relative to what? Thanks.

This is a great questions. As noted, the anemometer rating is in percent error. That said, what one see with failed anemometers is that, because of the increase friction:
a) at lower wind speeds (2 to 5 m/s or so), its 2% relative, but
b) at higher speeds (5 to 11 m/s?), theu are slower by, perhaps, .2m/s.Not a simple answer, to be sure…..
thanks
Eric
