In the testing system,testing errors affecte the accuracy of the testing data,and weakening effect of testing error is crucial for the result of test.Firstly,distribution and measurement about random errors are analyzed.Then data model based on LabVIEW testing system and ideal data model are built up.The system error at the type of figure is analyzed and inspection mean of the error system is studied.The paper offers the detection method of system error which bases on posterior testing statistical.Lastly,assessment indicators of systematic error and random error are discussed with revised data model.
