Dear Sirs, i just wanted to know if there is any method to test the accuracy of Symphonie Plus 3 data logger at site i.e. in case we want to check if the logger is properly recording (converting signals from anemometers / wind vane) the correct values of wind speed etc. A similar sensor testing is mentioned in application note. http://www.nrgsystems.com/TechSupport/KnowledgeBase.aspx?id=4&category=16 Regards, Zeeshan
