equal to the integration time set; each interval is preceded by the reset of integrated levels (see
chapter “DESCRIPTION OF THE DIFFERENT ACQUISITION MODES” on page 29).
This integrating mode, combined with Auto-Store function, enables to record on a time basis
equal to integration time Tint set, parameters shown on the SLM mode display together with spec-
trum both in octave and, if option is installed, in third octave bands. Integration time (that corre-
sponds to recording interval) can be set directly from SLM screen or using the specific menu pa-
rameter (MENU >> Instrument >> Measurements >> Integration time).
CONTINUOUS RECORDING
Pressing both REC and START/STOP/RESET keys starts the continuous data recording on
memory. The 3 parameters of SLM mode are stored twice per second, while the A weighted sound
level with FAST time constant is stored 8 times per second.
Press PAUSE to stop recording temporarily; press CONTINUE to restart it. As soon as you
go back to the RUN status, a special record is stored, containing indications about the possible erase
(see the “Back-Erase Function” in SLM mode on page 16) besides date and time.
The HOLD key does not affect data recording.
When the continuous recording is active, if the integration mode is set to
single , the integra-
tion time acts like a timer stopping automatically the acquisition as soon as the set time is elapsed.
Integration time is programmable from SLM display or using the relative menu item (Menu >> In-
strument >> Measurement >> Integration interval).
When integration mode is set to multiple , continuous recording do not stop when integration
time elapses: a special marker (“Last”) is stored together with the last data just before the integrated
levels clearing at the beginning of each integration period (see the chapter “DESCRIPTION OF
THE DIFFERENT ACQUISITION MODES” at page 29). The spectra are cleared in addition to the
statistical levels and the integrated parameters displayed on the SLM screen.
