Calibration.
Memory-Map Bike 270 Pro comes with built-in 3D electronic compass and barometer sensors. Calibration
for barometer is necessary at the start of each activity’s recording.
The 3D compass calibration is required to separate the earth's magnetic field from stray magnetic fields
emitted by something metallic/electronic like a car for which may affect the operation of the compass.
Without calibration, the 3D compass may have inaccurate readings.
As for barometer calibration, the Memory-Map Bike 270 Pro provides two methods for users to calibrate, i.e.
Auto calibration
and
Manual calibration
.
Manual calibration
is recommended when the user knows his true elevation there, for Manual calibration
uses the calibrated altitude as truth and assumes all changes in the pressure sensor are associated with the
barometric pressure, Manual calibration therefore will be more accurate
