Press PAGE to scroll to the altimeter page, and press MENU. Select Altimeter Setup.
- Auto Calibration
Once allows the altimeter to automatically calibrate one time when you start an activity. Continuous allows the altimeter to calibrate throughout the duration of your activity.
- Barometer Mode
Variable Elevation allows the barometer to measure changes in elevation while you are moving. Fixed Elevation assumes the navigator is stationary at a fixed elevation, so the barometric pressure should only change due to weather.
- Pressure Trending
Sets how the navigator records pressure data. Save Always records all pressure data, which can be helpful when you are watching for pressure fronts.
- Plot Type
Records elevation changes over a period of time or distance, records barometric pressure over a period of time, or records ambient pressure changes over a period of time.
- Calibrate Altimeter
Allows you to manually calibrate the barometric altimeter (Calibrating the Barometric Altimeter).
