Altimeter Plot Settings
Press PAGE to scroll to the altimeter page, and press MENU.
Reset: Resets the altimeter data, including waypoint, track, and trip data.
Altimeter Setup: Enables you to open additional altimeter settings (Altimeter Settings).
Adjust Zoom Ranges: Adjusts the zoom ranges shown on the altimeter page.
Change Data Fields: Allows you to customize the altimeter data fields.
Restore Defaults: Restores the altimeter to factory default settings.
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).
Calibrating the Barometric Altimeter
You can manually calibrate the barometric altimeter if you know the correct elevation or the correct barometric pressure.
- Go to a location where the elevation or barometric pressure is known.
- Press PAGE to scroll to the altimeter page.
- Press MENU.
- Select Altimeter Setup > Calibrate Altimeter.
- Select Method to select the measurement to use in calibration.
- Enter the measurement.
- Select Calibrate.
