Measuring indicators 1. Gage Repeatability: refer to the same appraiser analysis MSA, using the same measuring instrument MSA system analysis, multiple measurements of the measured values ??obtained when the same part of the same characteristics (data) deteriorated. 2. Gage Reproducibility: refers to evaluation by different people using the same measuring instruments, measuring the average variation when measuring the same part of the same characteristics. 3. Stability: refers to the measurement values ??obtained single characteristic measurement system on the same basis or in a certain part of the duration of the total variation. 4. Bias: refers to the same operator using the same measuring tools, measuring the same part of the same characteristics as many times as the average income and the use of more sophisticated instruments to measure the difference between the average value of the same MSA characteristics obtained from the same part of the definition, namely the observed average measurement results the difference between the value and the reference value, that is, we usually call "accuracy." 5. Linear: refers to the measurement system within the expected changes in the scope of work of bias. From the point of view of statistical quality control, measurement systems analysis is essentially within the scope of analysis of variance, namely analytical measurement system brought step process variation with respect to the size of the total variation, variation step process to ensure that the main step of the process itself stems instead of measuring system, the measuring system and the ability to meet the process requirements. Measurement system analysis, for the stability and accuracy of the entire measuring system MSA, which requires analysis of the position measuring system deteriorates, the width of variation. Including bias, stability and linear measuring system in the position deteriorated. Including repeatability, reproducibility of the measurement system variation in width. Measuring system can be divided into "Counting" and "measurement type" Measurement System categories. After the measurement can give specific measurement values ??are measured based measurement system; you can only give qualitative measurement results for the count type measuring systems. "Measurement type" Measurement system analysis typically includes bias (Bias), stability (Stability), linear (Linearity), and the repeatability and reproducibility (Repeatability & Reproducibility, called R & R). It may be conducted in the actual operation of measurement systems analysis while also options to determine depending on usage.
