Model 831 Manual View Spectrum Normalized 5-37
Overall Display
In general, obtaining a normalized display of 1/1 and 1/3
octave spectra appearing on the
Overall tab is the same as
for Live Displays, described in "Live Display" on page 5-30.
The major difference is that spectra appearing on the
Overall tab display Leq, Lmax and Lmin data
simultaneously, as shown in FIGURE 5-43.
FIGURE 5-43 Overall Spectrum
As a result, when setting up for View Normalized, if no
normalization spectrum has been selected, the display will
look as shown in FIGURE 5-44.
