ANNorsortie PO 131 Ed.?flwl EngWi i?M Norsonic AS. the ftgh qualily manulacturer of advanced sound analysers for more than 40 years, Is proud to prsent a new range of sound level meters. We have laken parts ol the unique technotogy (roni our more advanced analysers into a new simple sound level mler - lo give the users a reliable low cost SLM wtfh the well-known Norsonic quality. Thereby. our compl骨te range of sound level meters 1$ expanded to cover any need trom simple dB(A) measurement to advanced sound analysas. To give our customers the highest degree o( measurement accuracy and to follow...

PD 131 Ed.2 Rev.1 English 12.08 3 The different storage modes can be set in the memory menu. Manual Requires that the operator manually stores the acquired data before the next measurement is made. The instrument prompts the user to store before a new measurement begins, or before switching off the unit. Automatic The data is stored automatically each time a measurement is finished. Repeat Automatically storage of data and restart of next measurement using the same setup and duration. There will be a short time delay between each measurement due to internal memory housekeeping. Synchro Same as...

PD 131 Ed.2 Rev.1 English 12.08 4 Environmental noise assessments By adding the statistical LN function (option 2) the instrument will also provide the dB values in terms of the L5, L10, L50, L90 etc that are required to determine the impact of noise in the community. These measurements often require long term noise monitoring. With the clock synchronized automatic storage facility in the Nor130 series, repeated measurements may be performed with the results automatically stored to allow these long term measurements to be made, yet preserving the temporal data on the dispersion of the levels....

PD 131 Ed.2 Rev.1 English 12.08 5 Sound Power measurements The Nor130 series of instruments together with the Sound Power post processing and reporting program NorPower (Nor1035) is a powerful and budget friendly tool for CE noise labelling a machine according to the EU directive 2000/14/EC and the ISO 3740 series of standards Virtual Instrument. A virtual sound level meter is included in the delivery of the Nor130 series of instruments. This PC program allows the user to remotely control the sound level meter and simultaneously get a display of the instrument screen on the PC monitor. Also included...

PD 131 Ed.2 Rev.1 English 12.08 6 Real Time Frequency analysis (Option 1 and 4) The spectral weighting network A reports one value for the entire frequency spectrum. It is a sum of the entire noise. The same applies for C and Z networks. If a more detailed analysis is needed for parts of the frequency spectra, such as which frequency is domination the noise spectrum, or maybe comparing different noise spectra, the frequency analysis option is needed. The Nor130 series of instruments may be extended with 1/1 octave (option 1) or with 1/3 octave (option 4) frequency analysis option. Both options...

PD 131 Ed.2 Rev.1 English 12.08 7 Level versus time measurements (Option 3) Option 3, level vs. time enables the instrument to log the time profile like the classic level recorders used to do. The time profile is measured by dividing the total measurement into smaller periods of time, all having the same duration. The period length can be set from 1 second and upwards in 1 second steps. The logged parameters are LAeq, LAmax, and LCpeak. The level vs. time measurement is made in parallel with the basic sound level meter functions for the overall level; the global level for the entire measurement...
