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)
A 24 hours earlier
B Present
C Time periods for which history was not recorded (white
portion)
D Atmospheric pressure information in 90 minute 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, atmospheric pressure 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 j10 hPa 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 compared 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 1 m (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.
