Applicable modes:
Using the barometer
With the current atmospheric pressure as a reference,
it is displayed on the graph within the range of j10 hPa
to _10 hPa.
(Atmospheric pressure out of range cannot be
displayed in details)
A24 hours earlier
BPresent
CTime periods for which history was not recorded (white
portion)
DAtmospheric pressure information in 90minute intervals
•The barometer is an indicator of changes between fine weather and rain.
–When the atmospheric pressure rises: Weather tends to recover
–When the atmospheric pressure drops: Weather tends to worsen
Note
•In the following cases, atmosphe r i c pr es sure is not recorded on the graph.
–When [GPS Setting] is set to [ON], the battery is low, and the power is off
–When [Airplane Mode] is set to [ON] and the power is off
–When [Sensor Settings] is set to [OFF]
–[Underwater]
•When the displayable range (current atmospheric pressure of j10hPa to _10 hPa from the
reference pressure) is exceeded, the atmospheric pressure will not be displayed correctly.
∫About the measured altitude and atmospheric pressure
•Altitude value may show errors depending on the change in atmospheric pressure comp ared to
areas such as locations with altimeter reference signs. Perform frequently with [Adjust] in
[Altimeter].
•Altitude announced onboard an airplane is measured using the atmospheric pressure
surrounding the airplane. It does not match the altitude actually measured inside the airplane.
•Even if the unit is fixed at a constant altitude, the measured altitude may fluctuate due to the
effects of change in atmospheric pressure.
In coastal areas, the altitude changes by 1m (3.3 feet) per 0.12 hPa.
•Altitude and atmospheric pressure may not be measured
accurately in the following cases:
–When there is a significant change in weather conditions
(Pressure and air temperature)
–When there is a movement with a rapid change in altitude
–When pressure is applied to the front or rear of this unit¢1
–When this unit is wet (after using underwater, etc.)¢2
–When closing the side door¢2
¢1 Hold this unit as shown in the figure when measuring.
¢2 It will adapt to the ambient atmospheric pressure within a few minutes, and display correct
measurement values.
