Calibrating Barometric Pressure Readings (Offset); Specifying The Barometric Pressure Unit; Barometric Pressure Reading Precautions - Casio 5602 Operation Manual

Important!
To ensure correct barometric pressure
●
change indicator operation, enable it in
a location where the altitude is
constant (such as a lodge, camp area,
or on the ocean).
A change in altitude causes a change
●
in air pressure. Because of this, correct
readings are impossible. Do not take
readings while ascending or
descending a mountain, etc.

2.
Hold down (C) for at least two seconds.
If this turns on barometric pressure
change indication, [INFO ON] will stop
flashing and then the [BARO] indicator will
appear on the display.
3.
To disable barometric pressure change
indication, hold down (C) again for at least
two seconds.
Note
If Barometric Pressure Change
●
Indications are on, barometric
pressure readings are taken every two
minutes even while the watch is not in
the Barometer Mode.
The barometric pressure change
●
indicator becomes disabled
automatically 24 hours after it is
enabled.
You will not be able to turn on
●
barometric pressure change indication
if the watch's battery level is low.
Low battery power will also cause
●
barometric pressure change indication
to turn off automatically.

Calibrating Barometric
Pressure Readings (Offset)
The watch's pressure sensor is adjusted at the
factory and normally does not require
calibration. However, you can calibrate the
displayed value if you notice major errors in
readings.
Important!
The watch will not be able to produce
●
correct barometric pressure readings if
you make a mistake during the
calibration procedure. Check to make
sure that the value you use for
calibration produces correct pressure
readings.

2.
Hold down (E) for at least two seconds.
Keep the button depressed when [SET]
starts to flash. Release the button when
[SET] disappears from the display.
This displays the current barometric
pressure and enters the Barometric
Pressure Offset Mode.
3.
Use (A) and (C) to change the value.
Setting range: 260 to 1,100 hPa
Setting unit: 1 hPa
To return the barometric pressure
●
setting to its initial factory default, press
(A) and (C) at the same time.
4.
Press (E) to complete the setting
operation.
Specifying the Barometric
Pressure Unit
You can specify either hectopascals (hPa) or
inches of mercury (inHg) as the display unit for
barometric pressure values.
Important!
When Tokyo (TOKYO) is the Home
●
City, the altitude unit is fixed as
hectopascals (hPa) and cannot be
changed.

2.
Hold down (E) for at least two seconds.
Release the button when the name of the
currently selected Home City appears on
the display.
Example: When your Home City is Los
Angeles
3.
Press (D) eight times.
This causes [UNIT] to appear, with [hPa]
or [inHg] flashing.
4.
Use (C) to select a barometric pressure
unit.
[hPa]: Hectopascals
[inHg]: Inches of mercury
Hectopascals Inches of mercury
5.
Press (E) twice to complete the setting
operation.

Reading Precautions
The barometric pressure graph produced
●
by this watch can be used to obtain an idea
of upcoming weather conditions. However,
this watch should not be used in place of
precision instruments required for official
weather prediction and reporting.
Pressure sensor readings can be affected
●
by sudden changes in temperature.
Because of this, there may be some error in
the readings produced by the watch.
