What does repeatability refer to in calibration?

• A. The ability of a measuring instrument to produce the same result under unchanged conditions over multiple trials
• B. The capability of an instrument to function effectively over time
• C. The consistency of results across different measurement devices
• D. The overall accuracy of an instrument in various environments

Answer: (A)

Repeatability in calibration pertains to the ability of a measuring instrument to produce the same result under unchanged conditions over multiple trials. This means that if a consistent measurement procedure is followed, the instrument should yield the same output when measuring the same parameter several times. This is crucial in calibration, as it ensures that the instrument is stable and reliable for making accurate measurements. The emphasis on "unchanged conditions" signifies that repeatability is about the instrument's performance when factors that could influence the measurement are kept constant, such as environment, technique, and time interval between measurements. This characteristic is essential for quality control and assurance processes, as it helps in identifying whether the instrument is functioning properly and whether its calibration is effective. This understanding of repeatability helps distinguish it from other concepts like instrument longevity or cross-device consistency, which involve different dimensions of measurement performance.
