  1. Once raw data files (*.rwd files) have been imported, you can generate reports.  Go to SDR's Site menu, and choose View Database.  From the Select a Site screen, choose the site number for which you'd like to generate reports and click OK.


    The window will show the date range of imported data.  Click "Create New" button to set up what type of reports you wish to generate in the Create New Report screen.


    Select the Report Type from the drop-down menu, and then choose which channel to use for the report, and then click OK.


    To generate the report, put a check in the box to the left of the report, and click "Run Checked".


    Select the date range for the report, and click OK. 


    Please note that some types of reports present just one month of data at a time, so even if you choose a date range of 1 year, the software will generate 12 individual monthly reports.  The report(s) will appear on your screen, and you have the option to view them prior to printing.  The reports will be saved with a *.wmf (Windows metafile) file extension in an automatically created sub-folder within the Reports folder:



  2. On May 22, 2008 NRG Systems issued Technical Support Bulletin TSB-008 regarding the NRG #40C anemometer. Specifically, TSB-008 provided details on a manufacturing defect detected in the epoxy potting process of the sensor magnet that could cause a sensor to underreport wind speeds. It outlined corrective actions put in place and provided guidance to our customers on how to detect potential anomalies in collected data.

    In the weeks following this initial communication, we discovered that the problem was much more complex than we initially thought. Customers with new sensors were reporting similar problems with sensor slow-down obligating us to reexamine our initial conclusion. What appeared to be a simple root cause branched out into many possible causes. This required us to develop new science for analyzing and testing the performance of our anemometer. We concluded that the epoxy process was not the primary cause of wind speed underreporting. After this determination, we dedicated all available resources, solicited the help of outside materials experts to analyze the components and structure of the #40C, and designed and executed dozens of experiments. Additionally, we formed an industry roundtable and joined forces with other industry experts and consultants to better understand the problem.

    Some in the industry thought the interaction of the boom and sensor was the root cause of the slow down. While this may have been a contributing factor, we did not believe it to be the primary cause and we felt it was our responsibility to continue investigating the sensor itself.

    Through our exhaustive investigation we have explored and ruled out numerous possible causes. We can now report that we have recently confirmed, in both laboratory and field tests,  the underreporting of wind speeds by some NRG #40C anemometers is caused by the sensor entering into a vibratory mode. We have further confirmed that this vibratory mode is a state of the sensor itself and is not dependent on the boom or tower configuration. We now have enough solid information to begin the process of designing a solution.

    While we hope this news provides some assurance, we also know you seek answers now ? the reliability of your wind measurement data is of paramount importance. That is why we have scheduled a webinar for you to understand our progress to date and ask questions. Please see details below.

    We hope you will join us.

  3. Do you have a satellite iPack or GSM iPack?  A default configuration file should have been programmed into the iPack, but in case it wasn't, more detailed GSM iPack programming information can be found here:



    And satellite iPack programming information can be found here:


    Choose the document "Configuring the NRG Satellite iPack".

     If you are unable to resolve the problem, please contact NRG Tech Support directly at jma@nrgsystems.com or by phone, and we'll be glad to assist you.

  4.  The following is an explanation of how to export data from Symphonie Data Retriever (SDR) software so that it can be used in Excel or other spreadsheet programs.

    1)  Open SDR.
    2)  Click Site > View Database and select appropriate site: 


     3)  Click ?Import Raw Files':


     4)  Navigate to the appropriate directory and select all of the Raw Data Files (?SITE.RWD?).
    Note that by clicking CTRL+A, you can select all of the files in the directory.

    5)  Click ?Go!?, then Click ?Done!?.

    6)  Now to export, Click ?Export?.

    7)  Select the appropriate ?Date Range?, and Click ?OK?. 


     8)  Name the file, and save it as a ?Tabbed 10?min ASCII (*.txt)?:

     9)  The file will be saved in the C:\NRG\ScaledData folder by default, and you can now open the file in Excel or other spreadsheet program.

  5. If you add or replace a sensor at one of your monitoring sites, you will likely need to change the programming in your Symphonie logger.  The first raw data file you import after changes are made will result in a screen displaying the changes and the option to accept or ignore them.

    If you don't accept the changes, or if the changes you accepted are incorrect, you will need to manually update the site information in SDR's Site Information Editor window.  To open the Site Information Editor window, go to SDR's Site menu, and then choose "Edit Site".  From the Site Information  Editor screen, click the "History" button. 


     A table will appear at the bottom of the screen.  "Baseline" refers to the settings that were used when the logger began logging data.  New settings used after the Baseline settings will show up as additional entries in the table.  The Timestamp indicates the time and date when the baseline settings no
    longer apply and the beginning point when new settings should be used.

    To change settings, scroll to the appropriate logger channel using the arrow buttons.  Then click "Make New Change", and enter the date and time the change was made ("As of") and the new scale factor and offset information.  Remember that you can use the "Load Defaults" button to automatically enter default sensor programming information. 


    When a line in the History table is highlighted, any changes (such as the "As of" date, the scale factor, or offset) you make under "Sensor Information" in the screen above will be shown in the highlighted line in the table below.  Please note that the values in the table can't be directly edited; you must make changes in the screen above.

  6. From SDR?s main screen:





    Go to File menu, choose Batch Process, browse to wherever
    your Raw files are located


    Click on the first file you wish to import, hold down your
    Shift key on the keyboard, and click on the last file in the list you wish to
    import.  A batch of files will be selected:




    Click ?Open? and the ?Batch Processing??screen will appear:SDRscreen4.JPG

    Generally, you will want to Use predefined site parameters
    and Import data to site database by selecting those choices as shown
    above.  Typically ?Do not output text files? is left un-checked.

    Click ?Go?

    If this is the first time you have imported data from this
    site to SDR, you will see this screen:



    And will need to proceed with setting up the site
    information here:SDRscreen6.JPG


    Once that is completed, choose File, and Save Site, and then
    close the Site Information Editor window.

    Once it is closed, the files will import:




    When it completes, press ?Done!?
