5-6 824 Reference Manual 9/29/09
The following is a brief description of each of these
components:
Display label - The Display label identifies the display. The
example above shows the SLM view for the SLM+RTA
Instrument ID.
Selected detector - The selection determines which
detector’s data (e.g. Fast, Slow, Impl) is to be displayed.
Current SPL reading - Displays the current SPL reading
(as does the level of the moving bar on the far right of the
SPL history graph). The frequency weighting for SPL can be
selected: A, C, or FLAT. The detector can be selected from:
Slow, Fast and Impl.
All combinations of detector and
weighting are measured
simultaneously. The detector and
weighting selected in the “Settings”
menu are for measurements such as
Ln and Interval broadband levels.
Selectable reading - This is used to view a second level
which can be Leq, SEL, Min, Max, or Peak.
Weighting - This selection determines which weighting is
being displayed for the SPL and selectable reading. When
the selectable reading is showing Peak, the weighting for the
Peak can be set to: A, C or Flat (independent of the current
SPL frequency weighting).
Elapsed time - Displays the current run time for the
measurement. It resets to zero when the
R RESET key is
pressed, pauses when the
p PAUSE key is pressed, and
continues when the
p PAUSE key is pressed again. The
timer is displayed as mm:ss.ss, hh:mm:ss or hhhhh:mm.
