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

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 aected by the reference values

entered in the “Baro” and “Altitude” screens.

BAROMETRIC PRESSURE & ALTITUDE SETUP

Barometric Pressure data is automatically used as a

reference for Altitude, and both screens will show

accurate readings.
