You can choose between the following measuring methods:
– the profile method for fast analysis or
– the filter method for a more robust measuring method, although this will take longer.
The ’fast’ measuring method is generally sufficient. However, we recommend the ’robust’ measur-
ing method if the quality is insufficient, for example if the quality factor is less than 50.
