What is the difference between calibration and verification?

Question

Accepted Answer

Calibration adjusts instruments for accuracy; verification confirms their correctness against standards.

Calibration involves adjusting instruments to ensure they provide accurate measurements, e.g., calibrating a thermometer to read the correct temperature.
Verification checks if the instrument's output matches a known standard, e.g., verifying that a calibrated scale reads accurately against a standard weight.
Calibration is often a proactive process, while verification can be a reactive process to ensure ongoing accuracy.
In manufacturing, calibration might involve adjusting machinery, while verification could involve inspecting finished products against specifications.
