Optimising the correlation result using filters
Note:
The
SeCorr
system has filter options for various purposes. An
overview of these can be found in section 2.4 on page 20.
Filters can help optimise the correlation result and thus locate
leaks more reliably. Filters are set in the frequency graph.
A well-applied filter will have the following effect on the correla
-
tion curve:
●
Peaks will be displayed in higher quality, i.e. sharper, with
steeper sides, etc.
●
The peak of a potential leak noise will be accentuated com-
pared to other noises (e.g. sound interference).
Aim of optimisation
The aim is to obtain the highest quality peak possible in the cor-
relation curve.

Filter menu (overview)
The
Filter
menu displays the frequencies, correlation curve and
the result of the measurement as a graph.
