Parameters & Performance of Octave (00202) & 1/3 Octave (00303)
• Function : Noise’s real-time octave & 1/3 octave spectral analysis & integral measuring.
• Frequency weighting : Parallel (simultaneous) A, C, Z. The spectral analysis interface is composed by the frequency spectrum. The total analysis interface is realized by digital filtering. For the characteristics, see Appendix 1. Z weighting is added with one digital high-oass filter (cutoff frequency : 4Hz).
• Filter Type : Parallel (real-time) Octave and 1/3 Octave band filter, G=2, digital filter.
• Main menus : Octave, 1/3 Octave, Total, Setup, Data, Calibrate.
• Display interface : List interface, Graph interface.
• Measuring parameters : Lfmeq1s, Lfmeqt, Lxyp, Lxyi, Lxeq1s, LxeqT, LAE, E, Cpeak, Tm.
Note : fm is center frequency; X is frequency weighting A, C, Z. Y is time weighting F, S, I.
The noise exposure (E)’s measuring range is 0-65.535 Pa2h.
1/3 Octave (1/3OCT) measuring display (00303)
1/1 Octave (OCT) measuring display (00202)
• Data Storage : It can store 1/3 octave analysis’1s integral value and integral value as well as total analysis integral measuring result (max. 128 groups) The measuring result can be stored in Flash disk.
• Display resolution : 0.01 dB.
Statistical Analytical Software (00101)
• Function : Noise’s Statistic analysis & integral measuring.
