Calibrating the Barometric Altimeter

Your device was already calibrated at the factory, and the device uses automatic calibration by default. You can manually calibrate the barometric altimeter if you know the correct elevation or the correct barometric pressure.

  1. Go to a location where the elevation or barometric pressure is known.
  2. Select Elevation Plot.
  3. Swipe up from the bottom of the screen, and select  > Calibrate Altimeter.
  4. Follow the on-screen instructions.
