The measurement of repeatability of an instrument is referred to as precision. Precision indicates how consistently an instrument can produce the same measurement under the same conditions over multiple trials. When an instrument demonstrates high precision, it means that its results will cluster closely together, regardless of whether those results are close to the true value (accuracy). This concept is crucial in instrumentation and measurement because it reflects the reliability of the instrument in providing consistent readings.

Accuracy is different, as it refers to how close a measured value is to the true or actual value. Calibration relates to the process of adjusting an instrument to ensure its readings are accurate and meet specified standards. Stability refers to the ability of an instrument to maintain its performance over time, which impacts both precision and accuracy but does not specifically define repeatability. Understanding the distinction between these terms helps clarify measurement quality in instrumentation.
