Repeatability
It is a measure of precision. It is the «variation due to the measuring device. It is the variation observed when the same operator measures the same part repeatedly with the same device [1].» It «is similar to uniformity except that it deals with how consistent a particular sensor is against itself. It can be used to describe the ability of a sensor to provide the same result, under the same circumstances, over and over again [2].»
Stability
It is «a measure of how the accuracy and precision of the system perform over time [1].»

Precision
- Repeatability
- Reproducibility: variation due to the operators and the interaction between operator and part. It is the variation of the bias observed when different operators measure the same parts using the same device.»
Accuracy
- Bias: a measure of the difference between the true value and the observed value of a part. If the “true” value is unknown, it can be calculated by averaging several measurements with the most accurate measuring equipment available.
- Linearity: a measure of how the size of the part affects the bias of a measurement system. It is the difference in the observed bias values through the expected range of measurement [1].»
