The probe has to stand orthogonal with respect to the flow and it shall not be inclined:  

 

 

 

 

OK

 

NO

 

 
The probe is correctly positioned in the airstream when the measured value is the highest one.  
Carry out measurements pursuant to the indications provided in the first paragraphs of this chapter.

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.
