Alignment
The anemometer should be set to point North (or to another known reference direction),
using the North Spar, which can be identified from the red dot alignment indicator on the
base of the instrument. See Figure 2a.
If the unit is used in a tunnel, (and the Tunnel format is used), the unit would normally be
aligned with the N – S axis in the horizontal plane.
Figure 2a North Marker (Long Base Mount shown for illustrative purposes).
Pipe Mount units do not require the gasket and mounting ring.
