Selection of 1/1 OCTAVE analysis result to be saved in the buffer’s file - BUFFER position
The RMS or LEQ (when the user select A filter in FILTER position in SPECTRUM sub-list) result
from 1/3 OCTAVE analysis can be saved in the buffer’s file of the instrument. The selection of the
required result is made with the <

>, <

> push-buttons. The selection of the None text means that the
RMS or LEQ results are not saved in the buffer’s file. The user causes the return to the 1/3 OCTAVE
SETUP/ CHANNEL x sub-list pressing the <ENTER> push-button with the confirmation of the selections
made in the sub-list. The return to the 1/3 OCTAVE SETUP/ CHANNEL x sub-list is also possible after

Notice: It is not possible to change the values of the parameters during the execution of
the measurements. It is possible to open different lists and sub-lists but the positions in these lists are not
displayed inversely and so - not accessible. The “Loudspeaker” icon indicates that the instrument is in

Selection of the result which triggers registration in BUFFER mode in 1/1 OCTAVE
analysis of acoustic signal
In level meter mode only the result coming from the MAX detector of the one channel is used for
triggering purposes. In the case of vibration measurements it is VECT, VEC/SND or MAX value. The
SOURCE position is not accessible in that mode. However, in 1/1 OCTAVE analysis it is possible to
access mentioned above position and to make a selection. The results coming from the output of
