Abstract:
A method for adjusting a weather vane in which:the weather vane is placed, on site, in a site setting rig, and a position of an orientation sensor with respect to both a probe body and a vane of the weather vane is mechanically adjusted, wherein: at a factory, respective positions of the orientation sensor and of the probe body are fixed in a reference relationship, the probe body is placed on a first factory setting rig, the vane is kept in a sustained position which is mechanically known with respect to the first factory setting rig, and a first signal delivered by the orientation sensor for this vane position is measured, the weather vane, maintaining a same reference relationship, is subjected to a wind, obtained by a wind tunnel, of known direction with respect to the first setting rig, and a second signal delivered by the orientation sensor for a vane position corresponding to this wind of known direction is measured, on site, the probe body is placed on the site setting rig which is identical to the first factory setting rig, the vane is put back in the same sustained position with respect to the site setting rig, and a third signal delivered by the orientation sensor for this sustained vane position is measured, the position of the orientation sensor is mechanically adjusted so that the third signal is equal to a difference between the first and second signals.
