What does "Calibration Drift" refer to?

• A. A sudden change in instrument performance
• B. A gradual change affecting measurement accuracy
• C. A method for recalibrating instruments
• D. A technique used in software calibration

Answer: (B)

Calibration drift refers to the gradual change affecting measurement accuracy over time. This phenomenon occurs when an instrument's output or performance shifts from its original calibration point, leading to deviations in measurements that can compromise the reliability of data. In practical terms, as instruments are used over time, they may accumulate wear and tear, environmental influences, or changes in operating conditions that alter their sensitivity or response. Consequently, measurements may no longer align with established standards, making it essential for calibration technicians to routinely check and adjust instruments to ensure continued accuracy. This gradual deviation is different from a sudden change, which may indicate an immediate malfunction or impact due to external factors. Calibration drift emphasizes the importance of regular maintenance and recalibration to uphold measurement integrity and ensure consistently reliable results in various applications.
