Using Altimeter Profile - Suunto AMBIT3 PEAK 1.5 User Manual

profile when you started moving in the morning.You know that the
current altitude readings given by your Suunto Ambit3 Peak are
wrong. So, you hike to the nearest location shown on your
topographic map for which an altitude reference value is provided.
You correct your Suunto Ambit3 Peak altitude reference value
accordingly and switch from Barometer to Altimeter profile. Your
altitude readings are correct again.
Incorrect readings
If your Altimeter profile is on for an extended period of time with
the device in a fixed location while the local weather changes, the
device will give incorrect altitude readings.
If your Altimeter profile is on and the weather changes frequently
while you climb in altitude or go down in altitude, the device will
give you incorrect readings.
If the Barometer profile is on for an extended period of time as you
climb in altitude or go down in altitude, the device assumes that
you are standing still and interprets your changes in altitude as
changes in sea level air pressure. It will therefore give you incorrect
sea level air pressure readings.

3.2.3 Using Altimeter profile

The Altimeter profile calculates altitude based on reference values.
The reference value can either be sea level air pressure value or
altitude reference value. When the Altimeter profile is activated,
the altimeter icon is shown on the display.
