Calibrating Altitude Readings; Setting Up The Auto Measurement Interval - Casio 3475 Operation Manual

6.
While comparing the difference between
the altitude you found on the map and the
altitude differential displayed by the
watch, advance towards your destination.
Altitude differential indicator
Current location altitude
When the altitude differential you found
●
on the map is the same as that
displayed by the watch, it means you
are close to your destination.
Note
[-----] will appear on the display when a
●
reading is outside the allowable
altitude measurement range (±3,000
m (±9,840 feet)), or if a measurement
error occurs.
Calibrating Altitude
Readings
To minimize the difference between locally
indicated and measured values, you should
update the reference altitude value before
setting off on and during treks or any other
activities where you take altitude readings.
Also, you can ensure accurate measurements
by checking a map local altitude indications or
some other source for your current location's
altitude, and regularly calibrating watch
readings with the latest information while
mountain climbing.
Note
You can find out the altitude at your
●
current location from signs, maps, on
the Internet, etc.
Differences between actual altitude
●
and watch readings can be caused by
the factors below.
Changes in barometric pressure
ー
Changes in temperature caused by
ー
variations in barometric pressure
and by elevation
Though altitude readings can be taken
●
without calibration, doing so may
produce readings that are very
different from indications by altitude
markers, etc.
