In analyzing various phenomena, actual numerical value acquired from measurement has to be utilized to obtain accurate analysis and judgment. However, while making measurements, it surely encounters error in measurement system, which will affect the accuracy of the results. In order to analyze more accurately, the error in measurement system must precede deeper detection. Nevertheless, in the past, error in measurement system detection mainly depends on manual way, and measurement data are substituted into the existed equation to get the results. Therefore, aimed at the system error, and reducing the complexity of error in measurement system detection and improving the analysis efficiency in our approach. And also based on C language GUI, to develop a computer toolbox with two significant kinds of evaluation criteria and utilize the actual case to verify the accuracy of the toolbox. It not only can quickly detect the errors in measurement system, but also can greatly decrease manual computation, which contribute highly to the improvement of the accuracy and efficiency of error detection in measurement system.
