Altimeter
The watch’s altimeter uses a pressure sensor to detect current air pressure,
which is then used to estimate the current altitude based on ISA (International
Standard Atmosphere) preset values. You can specify a reference altitude,
which the watch will use to calculate your current altitude based on the value
you specify. Altimeter functions also include storage of measurement readings
in memory.
Important!
• This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
• The semiconductor pressure sensor used by the watch for altitude readings
also is affected by temperature. When taking altitude readings, make sure
the watch is not subjected to temperature changes.
• To avoid the effect of sudden temperature changes during readings, keep
the watch on your wrist in direct contact with your skin.
