3-2 System 824 Training Manual 2/19/98
In this display mode, you can see the
real power of the 824’s sound level
meter capabilities. In fact, you can
see 33 simultaneous values from the
parallel slow, fast, impulse detectors
with concurrently applied A, C, and
Flat frequency weighting filters.
You can also view the associated
SPL, Leq, SEL, Lmin, Lmax, Peak,
and Taktmaximal (German versions)
with the different detector and
weighting values.
Step 2 Press c to activate the “Any Data” viewing
mode. If the 824 is not running at this point,
do so by pressing the RUN/STOP s
The title at the top of the current screen should be
“Any Level”. This indicates that we are viewing the
live sound pressure level data from the 824.
Here you will see the current SPL
(Sound Pressure Level) data from the
Fast and Slow detectors. You will
also notice that the A, C, and Flat
frequency weighting is applied con-
currently to the data.
Step 3 Press r (or l) to cycle through the differ-
ent view screens. Stop when you get to the
“Any Level a” screen.
