CONTINUOUS RECORDING OF REPORTS AND EVENTS GROUPS
Performing the measurements in single integration mode, you can also record reports and
events, together with the sound level profiles. The parameters of the SLM and PROFILE screens
are included in the
Measurement group. Together with the Measurement group recording, you can
also enable the Report and Event groups recording.
The Report and Event groups are composed of the following storable parameters:
•
5 integrated parameters
•
Average spectra for octave and third octave band (with “Third Octave” option”)
•
Statistics
The Report group is recorded at programmable intervals, using the parameter MENU >> In-
strument >> Measurement >> Report Time, from a minimum of 1s to a maximum of 1 hour. The 5
integrated parameters, the spectra and the statistics are automatically cleared at the beginning of
every report time.
The 5 reported parameters can include:
•
FAST, SLOW and IMPULSE time weighted maximum and minimum levels
•
Peak level
•
Equivalent sound pressure level
•
SEL
•
Preset percentile levels L1, L2, L3 and L4
The enabling of the report time is an alternative to the multiple integration mode. The report time
can be set only in single integration mode.
The Event group is recorded, per each detected event (see paragraph “EVENT TRIGGER
FUNCTION” on page 27), at the end of the event itself. The 5 integrated parameters, the spectra
and the statistics are automatically cleared at the beginning, and are integrated for the entire dura-
tion of the event. The 5 event parameters can include:
•
FAST, SLOW and IMPULSE time weighted maximum and minimum levels
•
Peak level
•
Equivalent sound pressure level
•
SEL
The event trigger feature can be activated only in single integration mode. Therefore it is not
possible to enable event recording while multiple integration mode is selected.
When the Measurement group recording is activated together with the Report and Event
groups recording, the Measurement group continuous recording is enabled only with the events
sensed by the event trigger. This allows a lot of memory to be saved, minimizing information
losses: during the events the maximum quantity of logged information occurs, while with outside
sound events, the recording of the level is also carried out according to a reduced time resolution, as
defined in MENU >> Instrument >> Measurement >> Report time.
Fig. 12 shows the recording flow for the Report and Event groups.
The Measurement group recording interval is equal to 2 recordings per second.
In the following example, also the Report group items are memorized with a Report time amounting
to 10s.
