Calibration of Measuring Equipment and Machines

Measurement is one of the most important and critical activity in any process. People take important decisions based on the measurement. The decision to pass or reject a critical component e.g. in automobile or decision to administer suitable amount of dose to a critical patient primarily, depends on measurement. Quality of a process is ensured only by proper measurement & controls. Measurement needs to be accurate, repeatable with a known uncertainty and confidence. Fidelity of the measurement is ensured by proper & timely calibration. Hence, both measurement & calibration are equally importantfor the Quality of a process. This article covers various aspects of Measurement & calibration viz. Basics, Calibration process, Traceability and Uncertainty with a special emphasis on Electro-technical parameters.
