Calibrating the Barometer

Your device was already calibrated at the factory, and the device uses automatic calibration at your GPS starting point by default. You can manually calibrate the barometer if you know the correct elevation or the correct sea level pressure.

  1. Hold MENU.
  2. Select Settings > Sensors & Accessories > Barometer > Calibrate.
  3. Select an option:
    • To enter the current elevation or sea level pressure, select Yes.

    • To calibrate automatically from the digital elevation model, select Use DEM.

    • To calibrate automatically from your GPS starting point, select Use GPS.
