The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor. It also saves various types of altitude records and data.
Getting Ready
Before actually taking an altitude reading you need to select an altitude screen format and select an altitude reading interval.
You can select either of two screen formats for the Altimeter Mode
- Altitude tendency graph contents are updated each time you take an altitude reading.
- To take readings of the difference between the altitude at your current location and the altitude at a reference point, select Screen 2. See “Using an Altitude Differential Value” (page E-42) for more information.
