Calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Learn about the formal definition, the modern calibration processes, the quality of calibration , the measuring devices and instruments, and the instrument calibration prompts. General Description of Calibration Types of Calibration: Definition, Purpose, Instrument & Examples :- Calibration is the comparison of measurement results provided by a device under test with those of a calibration standard of established accuracy in measurement technology and metrology. Another known-accuracy measurement equipment, a device that generates the amount to be measured, such as a voltage or a sound tone, or a physical arte-fact, such as a meter ruler, could be used as a standard. Understand what calibration is, its purpose in ensuring measurement accuracy, and how it improves efficiency, compliance, and safety in various industries. Calibration is a process of checking and adjusting the accuracy of measuring instruments or equipment to ensure that they are functioning within their specified tolerances. Calibration is essential in ensuring the accuracy and precision of measurement instruments, and it is required in various industries such as manufacturing, healthcare, and laboratory testing.
