Altimeter Calibration
A barometer is an instrument for determining the pressure generated by the weight of the atmosphere. Users
can use their Bike 270 Pro to determine their immediate altitude and altitude gained/lost.
Barometer calibration is set to be automatically performed by default. However, users can set the device to
be manually calibrated.
Note:
If the device is set to Auto Calibration, the altitude will be gained from the following algorithm.
1. the first 5 log points in 5 seconds after GPS fixed are acquired.
2. the highest and lowest ones of the 5 log points are left out. There are 3 values remained.
3. Average the 3 values.
The auto calibration is performed every time when the device is turned on.
