What does 'repeatability' indicate in measurement?

Repeatability in measurement refers to the consistency of repeated results. When a measurement process is said to have high repeatability, it indicates that when the same measurement is taken multiple times under the same conditions, the results will be very similar or close to one another. This concept is crucial in ensuring that instruments and processes yield reliable data, allowing for confidence in measurement outcomes.

In scenarios where measurements need to be accurate and dependable—such as in manufacturing processes—having high repeatability ensures that variations in results are minimized, which is essential for quality control and consistency in production. The focus on consistency highlights the reliability of the measurement system, making it indispensable for applications where precision is critical.
