What is the process of adjusting a measurement device to ensure it measures accurately called?

• A. Measurement adjustment
• B. Taring
• C. Calibration
• D. Validation

Answer: (C)

Calibration is the process of adjusting a measurement device to ensure it measures accurately. By comparing the device’s readings with known reference values, you identify any deviation (bias or scale error) and adjust the instrument or its software so that future measurements align with the standards within the specified tolerance. This keeps measurements trustworthy across the device’s range and over time. Taring sets the zero baseline for a scale to ignore the container’s weight, but it doesn’t correct the instrument’s overall accuracy. Validation is about confirming that the instrument and its measurement process are acceptable for a specific use after calibration, not the act of adjustment itself.
