pressure changes as weather changes. The measurement interval is
10 seconds. The altitude reading remains steady and if the weather
changes, you will see changes in the sea level air pressure reading.
If you are moving in altitude (more than 5 meters of vertical
movement within 3 minutes), Suunto Ambit2 interprets all pressure
changes as movements in altitude.
Depending on which profile is active, you can access the Altimeter
or Barometer profile views with [View].
NOTE: When you are using the Automatic profile, barometer or
altimeter icons are not shown on the display.

FusedAlti
TM
provides an altitude reading that is a combination of
GPS and barometric altitude. It minimizes the effect of temporary
and offset errors in the final altitude reading.
NOTE: By default, altitude is measured with FusedAlti during
exercises that use GPS and during navigation. When GPS is switched
off, altitude is measured with the barometric sensor.
If you do not want to use FusedAlti in altitude measurement, you
can disable it in the options menu.
To disable FusedAlti:
1. Keep [Next] pressed to access the options menu.
2. Scroll to ALTI-BARO with [Light Lock] and enter with [Next].
