The invention discloses a method for examining initial readings of a wind tunnel measurement instrument. The method includes the steps of continuously collecting the initial readings of the measurement instrument for 10 seconds at sampling frequency of 200Hz to 500Hz before a wind tunnel test; calculating the collected initial readings to respectively obtain characteristic values, such as an amplitude-frequency characteristic, a mean value, a peak-to-peak value and a corresponding physical quantity, of each measurement instrument initial reading signal; subjecting the current characteristic values of each measurement instrument initial reading signal and characteristic values and property indexes of the normal instrument to comparative analysis to achieve the purpose of examining and conforming work states of the measurement instrument. When the method is used for examining the initial readings of the wind tunnel measurement instrument, the sampling frequency of the initial readings reaches up to 200Hz to 500Hz, the data size is large, and much information is carried; during comparative analysis, a signal frequency spectrum characteristic, the peak-to-peak value, the corresponding physical quantity, the current values and the like are extracted from a large number of data for analysis, so that examination of the initial readings is more thorough and comprehensive.
