When a register recovered from the memory is displayed on the screen, the sound level
meter uses the L
C
criterion level and the t
p
projection time set. This feature allows evaluations
for a register according to the criterion level L
C
and the projection time t
p
set on the sound
level meter.
1/1 Spectrum analyser screen (only DC112)
This screen shows, in real time, the following information:
• Graph of the equivalent continuous sound pressure level with the integration time
corresponding to the measurement time (
bars) in real time for the octave bands centred
on frequencies 63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz (with A frequency
weighting).
• Numerical value of the equivalent continuous sound pressure level with the integration
time equal to the measurement time for the selected octave band (
bar) (with A frequency
weighting).
• Central frequency of the selected octave band ( bar)
• Overall equivalent continuous sound pressure level with the integration time corresponding
to the measurement time and with A frequency weighting.
• Measurement time (t)
