What is calibration?

• A. The process of configuring an instrument to provide a result for a sample within an acceptable range
• B. A method for calculating measurement uncertainty in experiments
• C. A technique to ensure data integrity in scientific research
• D. The act of testing instruments for functionality without adjustments

Answer: (A)

Calibration is fundamentally the process of configuring an instrument to ensure it provides accurate results for a sample within a specified acceptable range. This involves adjusting the instrument so that its output aligns with a known standard or reference, which is essential for ensuring precision and reliability in measurements. By establishing the relationship between the instrument's readings and the actual values of the standards, calibration helps in identifying any deviations and making necessary adjustments to maintain accurate performance. This is crucial in various fields like manufacturing, pharmaceuticals, and environmental monitoring, where instrument accuracy directly impacts quality and compliance with regulatory standards. The other options, while relevant in certain contexts, do not define calibration. Calculating measurement uncertainty pertains to assessing the confidence level of measurements, ensuring data integrity involves maintaining accuracy and consistency of data over time, and testing instruments for functionality without adjustments relates more to performance validation rather than the calibration process itself.
