Leq
Press the
VView key again to
display the “View RTA” menu. Press
the
uup and ddown arrow
keys to highlight the desired display
and press the
c check key to select
the highlighted display.
The Leq display shows the equivalent level of all the
samples. A current or overall reset will reset the Leq.
NOTE: Leq, Max, and Min are measured only while triggered, if
triggering is enabled. If triggering is disabled they are measured
while the 824 is running by pressing the s R/S key. If Autostore is
enabled, Leq, Max, and Min will be reset at every trigger (or run if
Triggering is off), otherwise they will accumulate for each R/S
measurement until manually reset.
Max
The Max spectrum shows the maximum level obtained by
each filter and the maximum broadband (Flat) level. This is
a bin-by-bin maximum level. The Max spectrum is reset by
a current or overall reset and the R/S key when Autostore is
enabled.
