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.
Station pressure is displayed if the reference altitude is
set to zero. This is needed for ballistics solutions as well.
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.
Obtaining station pressure
• In the Main Setup Menu, use or to highlight
“Weather Mode”, then press .
• Use or to scroll to highlight the “BARO” screen
• Press to enter the “REF BARO” screen
• Set the reference altitude to zero for station pressure.
Set it to your current altitude if you want barometric
pressure
Baro—Displays current Barometric Pressure
Ref Alt—Use or to set the known Altitude
Sync Alt—Use or to switch “On” and sync the Baro
reading to the “Altitude” screen
When “Sync Alt” is turned “On,” the current
“Density Altitude” screen data is calculated from the
absolute values of station pressure, relative humidity
and temp., and is not affected by the reference values
entered in the “Baro” and “Altitude” screens.
