Suunto 9
4. Valid for barometer version only
The following features are only valid if your Suunto 9 has a built-in barometer.
4.1. Altimeter
Suunto 9 uses barometric pressure to measure altitude. To get accurate readings, you need
to define an altitude reference point. This can be your current elevation if you know the exact
value. Alternatively, you can use FusedAlti (see 4.2. FusedAlti) to set your reference point
automatically.
Set your reference point from the settings under Outdoor.
4.2. FusedAlti
FusedAltiTM provides an altitude reading that is a combination of GPS and barometric
altitude. It minimizes the effect of temporary and offset errors in the final altitude reading.
NOTE: By default, altitude is measured with FusedAlti during exercises that use GPS and
during navigation. When GPS is switched off, altitude is measured with the barometric sensor.
4.3. Altitude navigation
If you are navigating a route that has altitude information, you can also navigate based on
ascent and descent using the altitude profile display. While in the main navigation display
(where you see your route), swipe left or press the middle button to switch to the altitude
profile display.
The altitude profile display shows you the following information:
top: your current altitude
•
center: altitude profile showing your current position
•
bottom: remaining ascent or descent (tap screen to change views)
•
If you stray too far off from the route while using altitude navigation, your watch will give you
an Off route message in the altitude profile display. If you see this message, scroll to the
route navigation display to get back on track before continuing with altitude navigation.
4.4. Outdoor insight
Suunto 9 constantly measures absolute air pressure using the built-in pressure sensor. Based
on this measurement and your altitude reference value, it calculates altitude or air pressure.
