SETTING REFERENCE BAROMETRIC PRESSURE &
ALTITUDE: KESTREL 2500 & KESTREL 3500 ONLY
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 enter EITHER your location’s current
barometric pressure OR your current altitude.
*Station pressure is displayed if the reference altitude is set to zero.
Starting with Known Altitude for your Location
• Use
or to highlight the “BARO” screen.
• Press and simultaneously until the word “REF”
starts blinking on screen.
• Use or to adjust the value to the correct known
Altitude.
• Press and simultaneously to exit the reference
setting mode.
After the Altitude reference is set, place the unit on a table and allow
it to stabilize. The accurate Barometric Pressure reading will then be
displayed on screen.
Note the correct barometric pressure reading
above and use this measurement to set the
Altitude:
• Use
or to highlight the “Altitude” screen.
• Press and simultaneously until the word “REF”
starts blinking on screen.
• Use or to adjust the value to the barometric
pressure measurement noted above.
• Press and simultaneously again to exit the
setting mode.
Starting with Known Barometric Pressure for your
Location
• Use
or to highlight the “Altitude” screen.
• Press and simultaneously until the word “REF” starts
blinking on screen.
• Use or to adjust the reference value to the correct
known Barometric Pressure.
• Press and simultaneously again to exit the setting
mode.
After the Pressure reference is set, place the unit on a table and allow
it to stabilize. The accurate Altitude reading will then be displayed
on screen.
Note the correct altitude reading above and use this to
set the Barometric Pressure:
• Use
or to highlight the “BARO” screen.
• Press and simultaneously until the word “REF” starts
blinking on screen.
• Use or to adjust the reference value to the correct
known Altitude.
• Press and simultaneously again to exit the
setting mode.
Once these steps are complete, both screens will display
accurate readings.
*Be sure to adjust your reference measurements when you change your
location for altitude and/or barometric pressure or when there has been
dramatic change in weather conditions.
