Marker Text - (LOG, SSA)
One of the features of the 824 is the ability to
mark
or anno-
tate the SLM Time History as the instrument is running. This
allows the user to identify each noise source as the measure-
ment is being taken. There are 5
Markers
and each marker
can be assigned an 8 character description. See page 7-55 for
a description of the
Marker
display.
LOG and SSA Interval Settings
Interval Settings are available on the
LOG and SSA instruments.
The
Intervals
menu sets the System 824 to automatically
store at regular time periods, Leq, SEL, Lmax, Lmin, L
pkI
,
L
pkII
, and the six Ln levels. The Interval time period can
range from one second to nearly one hundred hours. The
Interval feature is particularly useful when monitoring noise
levels for extended periods of time because you can deter-
mine how the statistical makeup of the acoustic environment
has changed over time.
