9.2 Getting correct readings
If you are engaged in an outdoor activity that requires accurate sea level
air pressure or altitude, you will first need to calibrate your Suunto
Ambit3 Peak by entering either your current altitude or the current sea
level air pressure.
The altitude of your location can be found from most topographic maps
or Google Earth. A sea level air pressure reference for your location can
be found using the websites of national weather services.
If FusedAlti
TM
is activated, the altitude reading will be corrected
automatically using FusedAlti together with altitude and sea level pressure
calibration. For more information, see 9.8 FusedAlti.
Absolute air pressure is measured constantly
