Abstract：With the continuous development of meteorological services, the existing certification standards of measurement, the device can not meet current business needs. In order to achieve the automation of metrological verification system, Wind speed verification device for a full system upgrade. Therefore, the need for new Wind speed verification device of Uncertainty also determine if it meets the requirements of a value transfer system, essential work。In this paper, JJG431-86 "DEM6 cups light wind anemometer type test procedures" [1] under the conditions, the measurement process through the establishment of a mathematical model, based on JJF1059-1999 "Evaluation and Expression of Uncertainty in Measurement" [2] requires , the wind speed measurement uncertainty of test devices that were introduced with the assessment.
