TOTAL RMS values measured with A, C and LIN weighting filters. The read-out of the interested
spectrum value can be done by means of the cursor controlled by the <

right side of the display the selected 1/1 octave filter centre frequency (or the selected TOTAL) is given,
the units, and the weighting filter (dB A, dB C or dB in the case of the LIN) and the numerical value are
displayed.
