3.10.3 RESULTS LIST view mode
To get information about a
number of results at one time it is handy to switch to the “results list” view mode.
Up to three parameters at a time are accessible for the operator. In this view the user can scroll the list of
results starting from the profile name and configuration with the key.

3.10.4 1/1-octave analysis spectrum view mode
Note: The 1/1-octave analysis is switched on with the use of the Supervisor software
–
see
Chapter 6.3.5 .
Note: The 1/1-octave analysis is an optional function and should be activated before use. Activation
of the optional functions can be made with the use of the Supervisor software
–
see Chapter 6.2 .
The instrument operates as a real time 1/1-octave band analyser (RTA). In addition, and if enabled, 1/1-octave
analysis is performed in parallel with the dosimeter operations. All 1/1-octave digital pass-band filters (with 9
centre frequencies from 8 kHz down to 31.5 Hz; in base 10 system) are working in real-time with the broadband
frequency weighting filters (Z, A or C) and the linear LEQ detector. This enables the user to pre-weight
a spectrum with one of the selected broadband frequency curves if required for a particular application such
as the provision of hearing protectors in the control of high workplace noise levels.
Note: The three overall TOTAL LEQ results are measured with the weighting filters (A, C, Z) without
taking into account the settings of the level meters for profiles. The spectra are always linearly
averaged. Thus, the TOTAL values from 1/1 octave band analysis can be different from those
obtained for the profiles (if the LEQ Integration was set as Exponential).
