When the Averaged or Instantaneous
spectrum is selected, you can additionally
enable presentation of the Max and/or Min
values for each band by switching the Max or
Min parameters on.
The Max and Min spectrum is presented as a
stepped line – accordingly red and blue
colour.
NR and NC results view
In case of 1/1 octave Sound measurements
(S:1/1) noise rating (NR) and noise criterion
(NC) values can be additionally presented on
the same plot as a main spectrum when the
NR or/and NC parameter is enabled.
A violet line shows the NR results for the octave bands with central frequencies: 31.5Hz, 63.0Hz, 125Hz, 250Hz,
500Hz, 1.00kHz, 2.00kHz, 4.00kHz and 8.00kHz. A blue line shows the NC results for the octave bands with
central frequencies: 63.0Hz, 125Hz, 250Hz, 500Hz, 1.00kHz, 2.00kHz, 4.00kHz and 8.00kHz.
To enable the cursor to read the Max, Min, NR
or NC values, select the field in the lower left-
hand corner of the display with the ▲ / ▼ key.
Then select the appropriate value with the ◄
/ ► key pressed together with <Alt>.
The NR or NC results can be seen also in the
1 Profile and/or 3 Profile modes.
If the NC or NR result exceeds the maximum
value for which the curves are defined (NC=70
or NR=130) then before the displayed result
the character (>) appears and the highest
defined curve is displayed.
You can easily get into the Spectrum View
screen from the Spectrum view by entering
the result field (Leq/RMS) with the ▲ / ▼ key
and pressing <ENTER>.
10.3.4 Changing spectrum type in Vibration modes - Spectrum Type
In the Spectrum Type screen, which is
available only in Vibration modes, you can
select the different types of vibration spectra
to be presented in the Spectrum view:
