PERCENTILE AVERAGES
Shows the integrated values of the 7 percentile levels (values of the 7 percentiles that can be set in
the menu SETTINGS > SOUND MEASURE > STATISTICS).
The four columns display respectively:
•
LN broadband values integrated with linear average;
•
LN broadband values integrated with moving average (the number in seconds indicates the dura-
tion of the integration moving window);
•
LN values referring to # 1 frequency band (selectable);
•
LN values referring to # 2 frequency band (selectable);
MAXIMUMS - MINIMUMS
Shows maximum and minimum integrated values of significant broadband parameter groups.
SPECTRUM
Shows instantaneous, minimum, maximum and average values in thirds of an octave or octave (de-
pending on instrument settings) or frequency band values of other selectable parameters (LN per-
centile levels, events, ratios).
The parameter displayed on the column is user selectable.
SLM EXCEEDANSES
Shows the following exceedances:
•
parameter exceeded;
•
input/output thresholds;
•
exceedance status;
•
exceedances count.
MARKERS
Provides a count of the number of sound events (divided by name) identified by automatic or manual
marker that occurred during a measurement. A symbol representing a bell indicates whether the trig-
ger condition of the marker or event is active or inactive.
In this mode it is possible to:
•
Perform a measurement with or without recording.
•
Display the values of all parameters in real time during measurement/recording.
•
For some parameters, the desired display can be set (SPECTRUM).
8.3 Octave and Third Octave display (histogram)
The frequencies and amplitudes of the sound signal analyzed through IEC61260-compliant constant
percentage band digital filters are displayed in real time through a bar graph called a histogram. The
graph allows superimposition and activation or deactivation of 4 different color curves related to user-
selectable parameters and calculation modes even during measurement.
To access the HISTOGRAM mode (ISTOG.M):
1
from the home page select MEASURE menu;
2
Use the icons
to access the ISTOG.M screen;
3
Use the icons in the display.
