Once you have selected the screen you want, press to set the measurement process
in motion.
2.4.3 Functions display
The SC-30 measures all the functions simultaneously. Below is described the different ways
to display the acoustic functions while measurement is in progress. If you change the kind of
display, the octave band or the frequency weighting, the measurement continues. While
measurement is in progress, you cannot switch from the spectrum analyser mode to the
sound level meter mode.
Numerical analyser mode
This screen displays the following information in real time:
•
The equivalent continuous sound pressure level with T integration time for octave bands
centred on the frequencies 31.5, 63, 125, 250, 500, 1,000, 2,000, 4,000, 8,000 and 16,000
Hz (without frequency weighting).
•
The peak sound pressure level of the T interval for octave bands centred on the
frequencies 31.5, 63, 125, 250, 500, 1,000, 2,000, 4,000, 8,000 and 16,000 Hz (without
frequency weighting).
This screen displays also the following data in real time (press (left) or (right)
to view it)
•
The equivalent continuous global sound pressure level with T integration time and with
frequency weightings (A, C and Z).
•
The maximum of the peak sound pressure level of the T integration interval with frequency
weighting (A, C and Z).
By pressing you access the graphic analyser mode.
