6.4 Barometric Pressure Display
6.4.1 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. For further discussion of relative pressure and
calibration, reference Section 6.4.4.
6.4.2 Rate of Change of Pressure Graph
The rate of change of pressure graphic is shown to the left of the barometric pressure and signifies the
difference between the daily average pressure and the 30 day average (in hPa).
