Maria Vazquez Posted November 17, 2009 Report Share Posted November 17, 2009 Hello, I'm doing a wind analysis for a project. The wind data were collected for a period of 13 months. The data looked fine, however there are lots of missing data, once a week the logger stopped recording data at 03:50am until 7pm of the next day. This situation happens during 27 weeks consecutive and I don't know why. Thank you. Maria Link to comment Share on other sites More sharing options...
Aislan Posted January 3, 2013 Report Share Posted January 3, 2013 Hi, Maria! It might be the batteries. During the day (sunny time), the logger start to work again. Did you check it? Best regards, Aislan Theisen. Link to comment Share on other sites More sharing options...
David Carlson Posted January 8, 2013 Report Share Posted January 8, 2013 Good call Aislan. Maria, you can check the channel where an iPack Voltmeter SCM is installed to see what the voltages were like when the system was working. If there wasn't one, check the logger's internal voltage in SDR: Open Symphonie Data Retriever Software Load an RWD file Click "Read data" Click View > Volts / Temperature The graph at the bottom will show the voltage of the D cell batteries (~1.5V to 1.6V). If an iPack is present, the voltage will be 2.00V. Link to comment Share on other sites More sharing options...
