7.1.4
Conventional and integrating-averaging with storage mode
The integrator-averager mode completes the conventional mode always active (read above). It allows to specify an acoustic situation
indicating simultaneously:
•
The instantaneous, maximum or minimum sound pressure levels:
LXY
•
The equivalent continuous levels:
LAeq
and
LCeq
with a pre-programmed duration of
5 s, 10 s, 15 s,
30 s, 60 s,
or free
T.
•
The maximum peak pressure level:
Lcpk
•
Measurement duration
: 00:00:05
•
Main data are stored at the end of the measurement in order to get a usable file by the software
supplied with the instrument.
To start this mode:
➢
Choose an integration time among
5 s, 10 s, 15 s, 30 s, 60 s
or free
T.
➢
Press key.
LAeq and
LCeq
values are indicated, the timer indicates the measurement duration instead of time.
Note
:
RST
function is not available anymore in this mode.
During measurement:
It is possible to watch S1 or S2 screen with the scrolling knob key (also for conventional mode)
