Notes and Mechanism on Measuring Barometric
Pressure
About barometer feature
The watch uses a built-in pressure sensor to measure the atmospheric pressure of the current location.
Note:
This differs from the atmospheric pressure (sea level pressure) displayed in weather charts.
Notes on pressure measurements
This product is not intended for taking measurements that requires professional precision. Measurement function
readings are intended for general reference only.
About barometric tendency
❏
The barometric tendency is displayed based on the measurement results of atmospheric pressure for the past three
hours. If you continue measuring atmospheric pressure at the same location, you can use it as a guide for
predicting the weather.
❏
The barometric tendency measured and the actual barometric tendency at the measurement location may differ
due to differences in altitude due to movement to different heights, or rapid changes in weather and temperature.
❏
In environments where the atmospheric pressure changes rapidly in a short period of time, such as during a
typhoon, the measured barometric tendency may differ from the actual barometric pressure change.
