Calibrating altitude indication
About altitude indication
This watch measures atmospheric pressure with a specialized sensor and calculates
altitude by applying the standard atmosphere model (set by ICAO, International
Civil Aviation Organization) used for altitude measurement of civil aircrafts.
The standard atmosphere model sets a theoretical atmosphere and how pressure,
temperature, density and viscosity vary accompanying with change of altitude in it.
Therefore, expected altitude may significantly differ from actual one when the
weather changes drastically such as in climbing.
You can calibrate altitude indication by entering altitude already known.
• You can calibrate the value in the range of ±3 000 ft of currently measured
altitude.
