7 USING ALTI & BARO MODE
In the ALTI & BARO mode you can view the current altitude, barometric pressure
or snorkeling depth. It offers four profiles: AUTOMATIC , ALTIMETER , BAROMETER
and DEPTH METER (see Section 7.2.2 Setting profiles on page 26). You can access
different views depending on which profile is activated when you are in the
ALTI & BARO mode.
7.1 How Alti & Baro works
To get the right readings from ALTI & BARO , it is important to understand how
Suunto Core calculates altitude and sea level air pressure.
Suunto Core constantly measures absolute air pressure. Based on this
measurement and reference values, it calculates altitude or sea level air
pressure.
CAUTION: Keep area around sensor free of dirt and sand. Never insert any
objects into the sensor openings.
