Viewing Absolute vs. Relative Pressure
To switch between absolute and relative pressure, press and hold the
[PRESSURE -] button for two seconds.
Absolute pressure is the measured atmospheric pressure, and is a
function of altitude, and to a lesser extent, changes in weather
conditions.
Absolute pressure is not corrected to sea-level conditions.
Relative pressure is corrected to sea-level conditions.
