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 or vibration measurements
in accordance with ISO 20816-1:2016. All results can be
calculated in parallel by three virtual meters (so called
profiles) using different weighting filters and LEQ/RMS
detectors. When the Level Meter function is active the
SLM or VLM abbreviation appears in the icon line.
Measurement Function enabling calculation of
Level Meter results and 1/1-octave results for sound or
vibration measurements in accordance with Class 1
IEC 61260-1:2014. 1/1-octave results are presented as a
spectrum plot - a function of result value vs central band
frequency. 1/1-octave results can be saved as a time-
history. When the 1/1 Octave function is active the S:1/1
or V:1/1 abbreviation appears in the icon line.
Measurement Function enabling calculation of
Level Meter results and 1/3-octave results for sound or
vibration measurements in accordance with Class 1
IEC 61260-1:2014. 1/3-octave results are presented as a
spectrum plot - a function of result value vs central band
frequency. 1/3-octave results can be saved as a time-
history. When the 1/3 Octave function is active the S:1/3
or V:1/3 abbreviation appears in the icon line.
Measurement Function enabling calculation of
Level Meter results and 1/6-octave results for sound or
vibration measurements in accordance with Class 1
IEC 61260-1:2014. 1/6-octave results are presented as a
spectrum plot - a function of result vs central band
frequency. 1/6-octave results can be saved as a time-
history. When the 1/6 Octave function is active the S:1/6
or V:1/6 abbreviation appears in the icon line.
Measurement Function enabling calculation of
Level Meter results and 1/12-octave results for sound or
vibration measurements in accordance with Class 1
IEC 61260-1:2014. 1/12-octave results are presented as
a spectrum plot - a function of result vs central band
frequency. 1/12-octave results can be saved as a time-
history. When the 1/12 Octave function is active the
S:1/12 or V:1/12 abbreviation appears in the icon line.
Measurement Function enabling calculation of
Level Meter results and FFT spectrum for sound or
vibration measurements. FFT spectrum is calculated
based on Fast Fourier Transform algorithm and is
presented as a function of signal amplitude vs frequency
and can be saved as a time-history. When the FFT
function is active the S:FFT or V:FFT abbreviation
appears in the icon line.
Measurement Function enabling calculation of
reverberation time in 1/1-octave bands (from 63 Hz to
16 kHz) or 1/3-octave bands (from 50 Hz to 20 kHz)
including three total RMS levels (A, C and Z weighted).
This analysis is used for building acoustic purposes.
Depend on the type of the sound source used by the user
two methods can be applied: Impulse Response Method
and Interrupted Noise Method. Results are presented for
1/1 or 1/3-octave bands. When the RT60 function is
active the S:RT60 abbreviation appears in the icon line.
