Abstract According to JJF 1059.1-2012 Measurement Uncertainty Evaluation and Representation,the measurement error of digital anemometer will drift with the change of environmental factors such as time and temperature.In order to ensure the accuracy and reliability of the observed data,this paper uses digital anemometer as the research object,second-class standard pitot tube as a standard,introducing the general method and detailed assessment steps for measurement uncertainty of the wind speed measurement of digital anemometer.From the sources and classification of the measurement uncertainty results,an example is given to illustrate the evaluation method and the specific extended uncertainty evaluation value is also given out.
