15.1 MODES AND MEASUREMENT FUNCTIONS
The menu section enabling the selection of the
Measurement Function and perform Calibration of
the instrument.
Type of calculations the instrument currently
performs:
- Level Meter,
- 1/1 Octave,
- 1/3 Octave,
- Dosimeter,
- Running LEQ.
Measurement Function enabling measurement of
broad band results (Summary Results) and time-
history for sound 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.
Measurement Function enabling calculation of
broad band (Level Meter) and 1/1 octave sound
parameters in accordance with Class 1 IEC 61260-
1:2014. 1/1 octave results are presented as a
spectrum plot - a function of result vs central band
frequency and can be saved as a time-history.
Measurement Function enabling calculation of
broad band (Level Meter) and 1/3 octave sound
parameters in accordance with Class 1 IEC 61260-
1:2014. 1/3 octave results are presented as a
spectrum plot - a function of result vs central band
frequency and can be saved as a time-history.
Measurement Function enabling calculation of
broad band (Level Meter) and sound dosimeter
parameters.
