SVAN 979 User Manual
RMS detector selection
The Detector parameter defines the
LEQ/RMS detector for the 1/1-octave - 1/12-
octave analysis. For Sound measurements,
it is possible to select the Linear, Fast or
Slow detector. For Vibration measurements,
only Linear detector is available.
Note: The filter and detector settings in the General Settings and Profiles screens are used for the
level meter results in three profiles.
You can easily get into the Spectrum
screen from the spectrum view. It is
necessary to enter the function field (for
example 1/1) with the ▲ / ▼ key and press
<ENTER>.
