Probe performances, particularly at lowest speeds, depend on the friction with which the vane turns
around its own pivot. Low friction levels assure better performances. To guarantee this feature, it is
suggested neither to force, lock or rotate the vane with fingers, nor to position it, as much as
possible, in airstreams containing elements that might cause the probe to get dirty.
