Chapter
3.1
Level Meter Measurement Function enabling calculation of
broad band results ( Summary Results ) and time-
history for sound measurements in accordance with
Class 1 IEC 61672-1:2013 accuracy. All results can
be calculated in parallel by three virtual meters (so
called profiles) using different weighting filters and
LEQ detectors.
Chapter
3.1
1/1 Octave Measurement Function enabling calculation of
Level Meter results and 1/1-octave sound results in
accordance with Class 1 IEC 61260-1:2014.
1/1-octave results are presented as a spectrum
graph - a function of result value vs central band
frequency. 1/1-octave results can be saved as a
time-history.
Chapter
3.1 , 10
1/3 Octave Measurement Function enabling calculation of
Level Meter results and 1/3-octave sound results in
accordance with Class 1 IEC 61260-1:2014.
1/3-octave results are presented as a spectrum
graph - a function of result value vs central band
frequency. 1/3-octave results can be saved as a
time-history.
