AEH-MSA (Measurement System Analysis) uses mathematical statistics and charts to analyze the error of the measurement system to evaluate whether the measurement system is suitable for the measured parameters and determine the main components of the measurement system error. Since each evaluation index involved in MSA contains very complex mathematical statistics knowledge, each statistical characteristic also requires certain professional knowledge to understand and takes a lot of time to calculate. At the same time, it is also difficult to accurately reflect the analysis results on different types of charts. The MSA measurement system analysis function in our software is to solve these problems for quality management personnel.
