SETTING BAROmETRIC PRESSURE & ALTITUdE
The Kestrel meter measures “station pressure”, which
changes in response to both changes in altitude
and changes in atmosphere. Barometric pressure
is a measurement of the air pressure adjusted to
sea level. To obtain accurate barometric pressure
and altitude readings, you must first know EITHER
your location’s current barometric pressure OR your
current altitude.
Station pressure is displayed if the reference altitude is
set to zero.
Be sure to adjust your reference measurements for altitude
and/or barometric pressure when you change your
location or when there have been dramatic changes in
weather conditions.
