Altitude
Measurement
The watch takes altitude readings and
displays results based on air pressure
measurements taken by a built-in pressure
sensor.
Important!
●
The altitude readings displayed by the
watch are relative values that are
calculated based on barometric
pressure measured by the watch’s
pressure sensor. This means that
barometric pressure changes due to
weather can cause altitude readings
taken at the same location to be
different. Also note that the value
displayed by the watch may be
different from the actual elevation and/
or sea level elevation indicated for the
area where you are located. When
using the watch’s altimeter while
mountain climbing, it is recommended
that you regularly calibrate its readings
in accordance with local altitude
(elevation) indications.

Calibrating Altitude Readings
(Offset)
●
The altitude correction value you
specify and/or barometric pressure
changes may cause a negative value
to be displayed.
●
Check the information at the link below
to find out about how to minimize
differences between readings
produced by the watch, and values
provided by local altitude (elevation)
indications.

1. Enter the Altimeter Mode.

Navigating Between Modes
Entering the Altimeter Mode will start
altitude measurement and display the
altitude at your current location.

Altitude graph
●
The watch takes altitude readings every
second for about the first three minutes.
After that, it takes readings according to
the watch’s auto measurement interval
setting.
●
Check the information at the link below
to find out how to configure the auto
measurement interval.
l
Setting the Auto Measurement
Interval
●
To retrigger measurement, press (A).
●
To return to the Timekeeping Mode,
press (B).
Note
●
If the hour and/or minute hand is
located over the digital display when
you perform an altitude measurement,
the hands will temporarily shift to the
22-second or 38-second position to
allow easier reading of measurement
values. The hands will unshift to their
normal positions after about three
seconds.
●
When you enter the Altimeter Mode,
the function hand indicates the altitude
difference if the previous altitude
measurement was retained.
l
Checking the Altitude Differential
from a Reference Point
●
Measurement range: -700 to 10,000
meters (-2,300 to 32,800 feet)
(Measurement unit: 1 meter (5 feet))
Note that calibrating altitude readings
will cause a change in the
measurement range.
●
[- - -] will appear for the measured value
if it is outside the allowable range.

Calibrating Altitude
Readings (Offset)
To minimize the difference between locally
indicated and measured values, you should
update the reference altitude value (offset)
before setting off 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.
ー
Changes in barometric pressure
ー
Changes in temperature caused by
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.
