“uncalibrated” at the base of the Direction, Crosswind and Headwind screens and will not display or log
any values until it has been calibrated.

standing the Kestrel Meter up while taking readings in the field.) Finally, removing the impeller during
calibration is recommended. (Simply press on the edges of the impeller to pop it out, then press it back
