Store data
At the end of the measurement, in manual mode, a screen of all results is displayed. It is then possible to:
➢
Accept measurements and store them: move the cursor on

key to confirm. A banner displays the
storage phase.
➢
Reject measurements and not store them: move the cursor on

7.4 Measurement of noise equipment: NR mode
➢
Select
NR mode:
move the cursor with the arrows on the icon then press
OK
.
The sound level meter works as a frequency analyzer to determinate the noise level compared to a network of evaluation curves,
called NR (Noise Rating) curves as per NF S 30-010 standard.
It processes the sound signal according to two temporal modes:
•
On a free
T
measurement duration left to the initiative of the user with data storage for the determination of the NR index.
•
On a predefined measurement duration ranging from
3 s
to
60 s
with data storage for the determination of the NR index.
Measured and stared data at the end of the measurement:
•
LAeq, T:
equivalent continuous level of sound pressure on the T duration
•
LCeq,T:
equivalent continuous level of sound pressure on the T duration
•
LXeq, T
: equivalent continuous level of sound pressure on the T duration filtered by octave bands from 31.5Hz to 8 kHz
•
LUpk:
maximum peak level of sound pressure on the T duration
•
Measurement duration in
DD/HH:MM:SS
