The following explains each of the display’s components:
Display label - Shows the current display (for example,
“Ln-a”).
Percentage settings are entered with
a 1/100th dB resolution, but are
displayed to the nearest 1/10th dB
when 10 dB or greater.
Percentile values & levels - The L
n
(percentile levels) level
is that level which is exceeded ‘n’ percent of the
measurement time. By modifying the six settings you can
select any six percentile values to be displayed at a time. For
example, if you set one of these settings to 10.5, then L
10.5
would be one of the six percentiles that is displayed. The
value of L
10.5
is the level that has been exceeded 10.5% of
the time during the overall measurement.
