ATTENTION: As there are many versions of Thies First Class Wind Vane, only with versions 4.3150.X0.210 (10k?) is the connection direct to Symphonie data loggers.

Hello, 1) You can check the data logger voltage and internal temperature after you imported the RWD files into the data base. After importing, just open the site file NSD in Microsoft Access with reading option only and without converting the data base? There should be a table VoltsTemp with the information you want from the data logger. You can also get access to this information using Excel, but the steps are different depending if you have a more recent version of Office or not. 2) Regarding the iPack status, you can check the voltage at the comminication time that was configured in the iPack in the SDR main screen. If you installed the SCM card that comes wiht the iPack in one of the logger annalogue free channels you can check the 10min batery charge as if it was a sensor. Usually you show see the voltage around 12V and when the sun appears the voltage rises to about 14V and stays there until the sun sets. I don't know if it is possible to check the iPack error codes, but if you say you are receiving files it may be a problem with the cellular signal where you have the mast. You must be aware that the iPack will send full files only, if it is having poor signal. e.g. If you 1 daily communication, the iPack sends the full file of the previous day and the partial file of the day of communication from 00h00 until the communication time. If it is communicating every 2 days you get 2 full files of the previous 2 days and the partial file of the day of communication from 00h00 until the communication time. The same happens when communications are temporarelly interrupted. I hope this information helps. Regards, C.

Hello. Does NRG plan to present a new paper about the Dry Friction Whip issue and new conclusions regarding the longer time of operation of the modified #40 model? What is the effect of the Dry Friction Whip on wind speed standard deviation? Thanks.

Hello. My experience shows that wind vanes or data logger wind direction channels are prone to malfunction issues significantly more frequent than with other sensors or channels. I can say that 95% of problems we had was on wind direction and related with wind vane or data logger channels malfunction. Is there any way to improve this?

Hello. Thank you. However I notice that there calibration reports for download of sensors until 92012. Were these sensors not released? Best regards, C.

Hello Julia. Can you please specify the serial number of last sensor in the range of sensors with viratory mode? Thank you in advance. Best regards, C.

Hello, I also would like to know what is NRG position regarding the questions made by Fabianb. Can you please provide an answer? Best regards, C.

Hello, I don't know if it is the same situation. Although it didn't occour many times, we had masts that started sending a lot of partial files concerning the same day. In the wort cases we had one file every 10 minutes or without data. My advice is that you should replace the logger with a spare one as this is a situation that, usually, re-starts to occour after some time even if you performed a data logger reset. You can perform further tests at the office or send it later to NRG for checking. I think this is the best solution if you don't want to lose any raw data. Best regards, C.
