1/1-Octave and 1/3-Octave Analysis
1/3-octave analysis
The staircase shape on the display represents the 1/3-octave analysis result. From left, the
bars correspond to 12.5, 16, 20, 25, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, 250, 315, 400,
500, 630, 800, 1 k, 1.25 k, 1.6 k, 2 k, 2.5 k, 3.15 k, 4 k, 5 k, 6.3 k, 8 k, 10 k, 12.5 kHz. To
read the levels at these frequencies, use the and keys to move the marker to the desired
point. The frequency and level are then shown on the right of the screen under the indica-
tion "MARK".
Important
The frequency range of this unit including the microphone is
20 Hz to 12500 Hz. Outside of this range, precision is not
assured. Data for the 12.5 Hz and 16 Hz range should there-
fore be used only as a general reference.
