Altitude Reading
Precautions
Effects of Temperature
When taking altitude readings, take the steps
below to keep the watch at as stable a
temperature as possible. Changes in
temperature can affect altitude readings.
Take readings with the watch on your wrist.
●
Take readings in an area where
●
temperature is stable.
Altitude Readings
Do not use this watch while skydiving, hang
●
gliding, paragliding, gyrocopter flying, glider
flying, or engaged in other activities where
altitude changes suddenly.
Altitude readings produced by this watch
●
are not intended for special-purpose or
industrial level use.
In an aircraft, the watch measures the in-
●
cabin pressurized air pressure, so readings
will not match altitudes announced by the
crew.
Altitude Readings (Relative Altitude)
This watch uses International Standard
Atmosphere (ISA) relative altitude data
defined by the International Civil Aviation
Organization (ICAO). Barometric pressure
generally becomes lower as altitude
increases.
Correct measurement may not be possible
under the conditions below.
During unstable atmospheric conditions
●
During sudden temperature changes
●
After the watch has been subjected to
●
strong impact
Measured Altitude Value Adjustment
Using GPS Signal Data
If you performed a GPS signal receive
operation before starting measurement of an
activity that uses GPS signals for
measurement, the measured altitude value
will be automatically corrected when the
watch receives correction information. Note,
however, that this also may result in some
difference between the measured value and
the actual altitude.
Also note that the measured altitude value
adjustment operation using GPS signal data
may take a few minutes. The adjustment
operation may take even longer, depending
on your current environment. Regular manual
adjustment of the measured altitude value
using locally available information is
recommended. The watch will not use GPS
signal data to adjust measured altitude values
for one hour after you adjust the measured
altitude value manually.
