Product Data PD 850 Ed.1 Rev.1 English 01.11 Distributed Multichannel System Nor850 Norsonic is introducing a new concept in multichannel measurements; the Nor850 Distributed Multichannel System. By connecting a number of individual measuring units through various communication channels, the user may create the optimal multichannel system for any task. Dedicated user-friendly application packages for various uses are available, and the system control is done with a PC running the latest state-of-the-art Windows7 platform.

PD 850 Ed.1 Rev.1 English 01.11 2 Expandable The multichannel system Nor850 may be expanded as the needs grow. At the time of introduction, Norsonic is offering two front end choices for the confi guration of the measuring channels in a multichannel system: - Nor140 Sound Level Meter - Nor850-MF1 mainframe containing 1-10 measuring channels Start with two units of the standardized Nor140 SLM’s and increase step-by-step by adding additional Nor140 units. Or, choose the multichannel Nor850-MF1 mainframe containing up to 10 measuring channels. The user may even set up a mix with a few Nor140 units...

PD 850 Ed.1 Rev.1 English 01.11 3 Flexibility The concept of individual units for each measuring channel offers a very high degree of operating fl exibility. It allows the user to operate a multichannel system one day – and many individual measuring units another day! No need to store away an expensive multichannel system for months until the next big project turns up! This fl exibility is very well suited for building up a complete measurement system for larger laboratories with many measurement rooms. By placing one or more measurement channels in each measurement room, the full system may...

PD 850 Ed.1 Rev.1 English 01.11 4 Sensor database In the heart of the Nor850 software there is a sensor database containing all possible information about each customer complete list of measurement transducers (microphones, accelerometers, etc.), measuring channels, serial numbers, producers, calibration values, verification laboratories, verification dates, correction data, etc. By first time use the operator must key-in these data tom the system. Next time, however, as soon as any of the known transducers and measuring channels is connected, all data are automatically available within the Nor850...

PD 850 Ed.1 Rev.1 English 01.11 5 Measurement setups The settings for the next measurement is done in the Measurement Menu which expands on the screen by a click on the Measurement tab. Within this menu, the operator sets the miscellaneous measurement parameters and functions. These include overall measurement duration, profile measurement resolution, filtering bandwidth, upper and lower frequency limitations, weighting networks, time constants, statistical percentiles, and finally the required measurement functions. Transducer calibration Prior to the measurement, each microphone or transducer...

PD 850 Ed.1 Rev.1 English 01.11 6 The application package for building acoustics is designed with two objectives in mind. Advanced laboratories with multiple test facilities require a system that offers great flexibility in the miscellaneous operational test tasks, including rapid setup of previous test procedures and the ability to use sophisticated measurement techniques. And yet the measurement system should be easy and efficient to use for the operators in order to produce test reports at the lowest possible number of man hours. Preset measurement Standards The system is delivered with preset...

PD 850 Ed.1 Rev.1 English 01.11 7 Intelligent measurement control The screen will show the operator all the vital data at any time during the sound insulation test. Simply start by dragging the available measurement channels into the Source- or Receivewindow. Then the system knows which measurement channels that deliver source-room results and which channels that deliver receiving-room results. The operator may even alternate channels between the two measurement rooms during the test without any undesired mix of measurement results! Before each individual measurement, the operator should select...

Hence, details about the measurement object, conditions, project numbers, etc. may easily be edited by the operator. The report may be printed out on a color printer or send to the client as a .pdf document.
