Nor850 Software

          Nor850 Software Suite Overview


           Nor850 Building Acoustics Module for Field Measurements





Up to 4 different display views may be configured. A display view may be a single view or dual view. The VIEW button scrolls through the different display views. Each graphical display is accomplished by a numerical display. Just push the TBL button to toggle between numerical and graphical. A display view may be a combination of data from sound channel one and two. More than 60 measurement parameters may be logged simultaneously. The user may select up to 10 parameters to be displayed in each view, where three can be displayed on the screen simultaneously. The FUNC button scrolls through the selected parameters if more than three are selected.



A new generation of remote control and data acquisition from a sound level meter!
Use your smartphone or notepad to connect with your sound level meter.
The Nor150’s built in web server opens up a new world of remote communication and acquisition of data from a Sound level meter. Simply connect to your instrument via LAN, GPRS or WiFi using a web browser to control, download or view the measurement in real time. The program covers all applications from downloading files to full control of your analyser to add markers, start a recording or just check the battery status.



Measurement Parameters

Simultaneous measurement of SPL, Leq, LeqI, LMax, LMin, LE, LEI, LPeak, Ln and Tmax5.
Time weighting functions: Fast, Slow and Impulse (Simultaneous).
Spectral weighting functions: A, C and Z - weighting (Simultaneous).
Frequency analysis: 1/1 and 1/3 octave real time filters from 0,1Hz to 20 kHz.
Statistical calculations: 8 individual adjustable percentiles from L0,1% to L99,9%, The statistical calculations are performed in real time within each frequency band and for each profile period if period length is set longer than 2 minutes. User can select between Fast or Slow time weighting as basis for the statistical calculation. 
Measurement Control

Time profile resolution: 10ms – 24 hours including full frequency spectra.
Overall measurement duration: 1 sec – 7 days. (If set to Repeat or Synchro mode a new measurement will be started automatically, with no time gap between each measurement.)
Back erase in Pause mode: 0-20 sec free selectable graphical back erase.
Audio Recording
12 and 48 kHz sampling rate / 8 , 8MU, 16 and 24 bits / 5 sec pretrigger.
Measurement Range
One range covering 120dB without any range adjustments.
Self noise measured with ½” microphone with a nominal sensitivity of 50mv/Pa: 17dBA.
Maximum RMS level 137dBA, Maximum Peak level 140dB PeakC.
The high SPL mode enables measurements up to 194dB using a suitable 1/4” microphone.
Built in GPS for position and exact time synchronization.
4,3” colour display, ¼ VGA with capacitive touch. Scratch-proof display glass with anti-smudge coating.
Built in GPS for position and exact time synchronization.
Built in Camera for annotation before, during and after a measurement. Camera can be set up to capture noise event based pictures.
