Compass calibration
Unlike other wind vanes, Windbird does not need to be oriented with respect to north. It includes an electronic compass.
However, it is absolutely necessary to calibrate Windbird's compass.
The earth's magnetic field varies at each location. This is why calibration must be carried out at each installation site, just before mounting Windbird on its mast.
If you were familiar with the Pioupiou device, forget all about it. The Windbird calibration procedure is different.
