INDSCREEN PROTECTION
The SA 209 foam reduces the effect of wind on measurement results.
Note: The windscreen influences the free-field characteristics of the instrument, therefore it is
important to check its condition regularly. In the case of visible degradation of the foam surface it
must be replaced by the new one.
During continuous usage, the SA 209 foam is exposed to different weather conditions with possibility of
causing mechanical damage to the foam’s structure. Therefore, it is recommended, at least once a quarter
(3 months), to check the condition of the foam by examining the surface for cracks by squeezing the foam.
If cracks or holes are observed, the
SA 209
foam must be replaced.
The SA 209 foam must be replaced whenever squeezing it causes severing of small pieces of its surface.
Replacement of the foam windscreen should be performed according to steps 1 to 5 of Chapter
steps 8 to 12 of Chapter
