9 USING ALTI & BARO MODE
In ALTI & BARO mode you can view the current altitude or barometric
pressure. It offers three profiles: Automatic, Barometer and
Altimeter. For information on setting profiles, see 9.4.1 Setting
profiles.
You can access different views depending on which profile is activated
when you are in ALTI & BARO mode.
Sunrise and sunset time views are available when GPS has been
activated. If GPS is not active, sunrise and sunset times are based on
the last recorded GPS data.
9.1 How Alti & Baro works
To get correct readings with ALTI & BARO mode, it is important to
understand how Suunto Ambit3 Peak calculates altitude and sea level
air pressure. Suunto Ambit3 Peak constantly measures absolute air
pressure. Based on this measurement and reference values, it
calculates altitude or sea level air pressure.
CAUTION: Keep the area around the sensor free of dirt and
sand. Never insert any objects into the sensor openings.
