The Kestrel employs a stable, accurate pressure sensor to
measure station pressure, the unadjusted air pressure in
your location.
» To use your Kestrel to measure barometric pressure
(station pressure adjusted for local elevation), you
must enter a correct reference value for your altitude.
Accurate barometric readings require that no elevation
changes be made while taking measurements.
» To use your Kestrel to measure altitude changes
(changes in station pressure associated with changes
in elevation), you must enter a correct reference
value for your starting barometric pressure. Accurate
altitude readings depend on stable, weather related
barometric air pressure while measurements are taken.
» Synched values between the Altitude and Barometer
measurement screens allow reference value updates
on either screen to automatically update reference
values on the other.
Note! You cannot use your Kestrel as a barometer and altimeter
simultaneously.
ALTIMETER AND BAROMETER
SETTING REFERENCE VALUES ON BARO
MEASUREMENT SCREEN:
» Scroll to the Baro measurement screen and
select Settings.
» Adjust either the Altitude or the Barometric
Pressure value to a local, known value obtained
from a mapping reference, GPS, or accurate
weather station in the same location.
SETTING REFERENCE VALUES ON ALTITUDE
MEASUREMENT SCREEN:
» Scroll to the ALTITUDE measurement screen
and select Settings.
» Adjust either the Altitude or the Barometric
Pressure value to a local, known value obtained
from a mapping reference, GPS, or accurate
weather station in the same location.
Note! You should enter new reference values whenever
you are using the Altimeter or Barometer functions and
your reference value is no longer accurate (Ref Baro
for Alt, Ref Alt for Baro) due to a change in weather or
location.
