This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.
To take barometric pressure and temperature readings
Enter the Barometer/Thermometer Mode (page E-27).
• This will automatically start a barometric pressure/temperature reading operation, and the results will appear on the display in about one second.
• Readings will continue to be taken about every five seconds for the first three minutes, and then about every two minutes thereafter.
• You can restart the reading operation from the beginning at any time by pressing C.
Note
• Press D to return to the Timekeeping Mode.
• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about 1 hour after entering the Barometer/Thermometer Mode.
