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 Ambit2 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
