GETTING STARTED
Turning ON and OFF
•  Press   to turn on.
•  Hold   for 3 seconds to turn o. 
 The Kestrel Meter will automatically turn o if no buttons have been 
pressed for 45 minutes.
Select Measurement Mode
•  Use   or   to access each Measurement screen
•  The instantaneous Measurement value will be displayed  
  on each screen and updated once per second.
 Each Measurement screen will ash a brief “Hint” to clarify which 
Measurement is being displayed. Note: Hints are not displayed in the 
Kestrel 1000.
The Measurement’s icons and  units of measure will be displayed in the 
lower line of the screen.

SETTING REFERENCE BAROMETRIC PRESSURE &

 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 rst 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.
SETUP + OPTIONS
Select the Unit of Measure
•  Select the unit of measure. While holding   , press   
  to scroll through the available units of measure for that 
  measurement.
