3.3. ALTI/BARO MODE

The Alti/Baro mode has two alternative displays: Altitude and related parameters in

Alti use and weather data, such as barometric pressure and temperature, in Baro

use. With the Use selection you can select whether you use this mode as an altimeter

or as a weather station. The Alti/Baro mode also contains the weather memory and

the reference setting needed to relate the current weather state to your current

altitude.

With this function you can set your Suunto t6 to display either barometric or altitude-

related information. It also defines whether the Training logbook records an altitude

profile or not.

When the Alti use is active, your Suunto t6 assumes that all the barometric pressure

changes are due to altitude changes. The logbook in the Training mode records

altitude data. Alti is intended for measuring the altitude whenever you are on the

move. However, since substantial barometric pressure changes can take place during

a day, you should compare the changes reported by your Suunto t6 to well-known

references. If these differ from each other too much, the reason is the weather

change and you should set a new reference value as advised in section 3.3.4.

Reference altitude and barometric pressure. A general rule is that a 10 m change in

altitude equals 1,2 hPa in the barometric pressure at sea level and 0,5 hPa at 8000 m.

When the Baro use is active, your Suunto t6 assumes that all the barometric pressure

changes are due to weather changes. The training logbook does not record altitude

data. Baro use is practical for following and predicting weather trends when staying in

a constant altitude.
