Checking Barometric Pressure Changes and Trends
Your watch provides the three methods below for checking barometric pressure changes and trends.
•
Checking the latest change in barometric pressure (Barometric pressure differential pointer described
below)
•
Checking barometric pressure changes for the past 20 hours (Barometric Pressure Graph, page E-47)
•
Checking for signifi cant barometric pressure changes (Barometric Pressure Change Indicator, page
E-49)
Barometric Pressure Differential Pointer
Your watch automatically takes barometric pressure measurements every two hours (at the 30 minute
mark of each even numbered hour), regardless of the mode it is in.
The second hand of the watch indicates the difference between the current barometric reading and
previous automatic reading, within the range of ±10hPa (1hPa unit). This keeps you informed about
current barometric pressure changes in your area.
