The Edge 810, 800 and 510 calculate elevation data using a barometric altimeter. Once the device is properly calibrated, the standard area of accuracy will be +/- 10 feet. To ensure that elevation data is accurate at the beginning of an activity, calibrate the elevation manually.

To calibrate the elevation manually:

  1. Touch Setup menu (tools icon) on Main menu
  2. Touch System
  3. Touch GPS
  4. Select Set Elevation
  5. Set elevation to known elevation of starting point
  6. Select check mark

The elevation will then be calibrated from this manually set elevation.

The barometric altimeter is not temperature compensated. Temperature changes in the measuring device will affect the barometric pressure sensor and altimeter readings.
