4.2.1 Filter
The frequency filter setting can be changed in the
filter
menu.
The band pass of the filter can be adjusted from 1 Hz to 9950
Hz; it is at least 300 Hz wide.
Leak noises have different ranges in which they can be heard
particularly well. Even the same sound is perceived differently by
different people. A band pass can be set to optimize the acoustic
perception. This means that only one particular frequency range
will be relayed to the headphones. You can either find the best
setting yourself by trial and error or the
AC 06
can search for it
automatically.
Automatic search for the best frequency range
With the filter optimization function the
AC 06
can automatically
search for the best frequency range provided this is done when
there is little background noise interference. Furthermore, the
noise from the leak, in particular the ground noise, should already
be discernible.
Automatic
The
AC 06
records and analyzes a “noise sample”.
The display will show various frequency ranges during the
analysis process. You will also hear on the headphones the
noise produced from the displayed filter values.
The
AC 06
sets the frequency range which distinguishes the
leak particularly vividly.
Default
Here you can reset the default band pass setting (factory set-
ting) for the probe that is currently plugged in. The band pass
setting for other probes will not be reset.
