See Appendix A for a general discussion on how to set various wind
sensors to true north.
1. Ensure that the rotor of the Vector wind speed sensor and
the vane of the wind direction sensor are correctly fitted,
as described above and in the sensor manuals. Failure to
do so can lead to false measurements or damage to the
sensors.
2. Do not attempt to remove the rotor of the wind speed
sensor or the vane of the wind direction sensor while the
sensors are fixed to the cross-arm. The correct procedure
is described in the sensor manuals.
