Stability in a temperature source shows how steady the temperature remains with time at a fixed location after the set temperature is reached. In calibration, good stability is essential because it improves repeatability, reduces measurement uncertainty, and supports reliable comparison between the reference standard and the instrument under calibration. This article explains stability in simple language with examples, calculation method, common causes of poor stability, and practical ways to improve it.
Calibration is the process of comparing a measuring instrument with a known reference standard to check its accuracy. It helps identify error, apply correction where required, maintain reliable measurements, support audits, and build confidence in quality decisions.
