ALTIMETER CALIBRATION
Before use, the altimeter must be calibrated.
Since an altimeter uses pressure to determine the altitude
and pressure varies from place to place, it is important to
set the altimeter to a known reference altitude value, or
to a standard reference altitude of a given place. Sudden
changes in pressure due to changes in weather can cause
your altimeter reading to be off by +-100m (328 ft), even
