14.1 MODES AND MEASUREMENT FUNCTIONS
The menu section that enables selecting the
Measurement Function and performing
Calibration of the instrument.
Type of calculations the instrument currently
performs:
- Level Meter,
- 1/1 Octave,
- 1/3 Octave,
- Dosimeter,
- RT60.
Measurement Function enabling calculation of
broad band results (Summary Results) and time-
history for sound measurements in accordance
with Class 2 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.
Measurement Function enabling calculation of
Level Meter results and 1/1-octave sound results
in accordance with Class 2 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.
Measurement Function enabling calculation of
Level Meter results and 1/3-octave sound results
in accordance with Class 2 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.
Measurement Function enabling calculation of
broad band (Level Meter) and sound exposure
results in accordance with Class 2 IEC 61672-
1:2013 accuracy.
