  1. thanks for your message! the best way to diagnose what may be happening will be to send the RWD files in question to support@nrgsystems.com. the Tech Services team can take a look to see what might be going on. i can see from the screenshot that the file was pulled from the SD card directly (hardware rev ends in '000'). did the file send via email as well?
  2. It appears that you are working with exported data files from a SymphoniePLUS3 or older logger. The files the logger creates are in RWD format - a proprietary binary encoded file. The data in these files is stored as raw counts and pulses; unscaled. At the time of export, the data is scaled. it may be scaled per the logger settings (stored in the file) or scaled using settings in the Site file. The information in the header of the exported data, as you show in your original post, indicates how the sensor was scaled at the time of export. If you wish to change the scaling of the
  3. Hello HuQin, Thank you for your message. Since the upgrade of our website, the apnote can be found here: https://www.nrgsystems.com/assets/resources/Automation-of-SDR-AppNote.pdf If you would prefer to convert using the settings in the file (rather than an NSD site file) use the /q option, like: ``` SDR.exe /q 043420160309550.RWD ``` If your file has a PIN, use the /z option: ``` SDR.exe /z 1234 043420160309550.RWD ``` Cheers, Dave
  4. The hardware revision numbers relate to the firmware/hardware of the logger and iPack. You're getting this message because the site file record for the iPack firmware is 057. The new data file coming in shows that the iPack's firmware has been UPGRADED to 062. If you click YES when you get this message, it will update your site file to include this new record and you will no longer get this message. I hope that helps. Let us know if you have any more questions!
  5. I had recently helped a customer configure automatic file extraction on a Mac computer, and thought I would share the details here.   This option works for all builds of Windows, MacOS and Linux, and can be used for data files from any Symphonie data logger - including SymphoniePRO     Install Mozilla Thunderbird (https://www.mozilla.org/en-US/thunderbird/) Search for the Add-on “attachment extractor” [sharedmedia=core:attachments:32]   Install it Restart Thunderbird In the Add-ons manager, under Extensions click Preferences for the AttachmentExtractor [shared
  6. Meteorological data is time stamped so that it can be readily incorporated and compared with other data sets. In order for this to be done properly the clocks in all loggers must be synchronized. Most loggers use quartz crystals for their real-time clocks. This is a very accurate approach; for example, a quartz wristwatch will drift about a half second per day when worn. However, this type of clock is susceptible to changes in temperature. A quartz clock running outside in the elements is more likely to drift on the order of 6 seconds per day. In order to compensate for this internet time
