Suunto TRAVERSE series User Manual page 23

NOTE: If you are wearing your Suunto Traverse on your wrist, you
will need to take it off in order to get an accurate temperature reading
because your body temperature will affect the initial reading.
3.2.5 Using Automatic profile
The Automatic profile switches between the Altimeter and Barometer
profiles according to your movements. When the Automatic profile is
active, the device will automatically switch between interpreting
changes in air pressure as changes in altitude or changes in weather.
It is not possible to measure weather and altitude changes at the same
time, as both cause a change in the surrounding air pressure. Suunto
Traverse senses vertical movement and switches to measuring altitude,
when needed. When altitude is shown, it is updated with a maximum
delay of 10 seconds.
If you are at a constant altitude (less than 5 meters of vertical
movement within 12 minutes), Suunto Traverse interprets all pressure
changes as weather changes. The measurement interval is10 seconds.
The altitude reading remains steady and if the weather changes, you
will see changes in the sea level air pressure reading.
