Learn about the meaning of calibration, calibration uncertainty, traceability, why and how often to calibrate and how to calibrate.
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy.
What Is Calibration? Calibration is configuring and verifying a measuring instrument's accuracy to ensure its readings match a known standard. Calibration is a foundational practice across healthcare, electronics, manufacturing, and environmental monitoring.
The process of comparison of a device with unknown accuracy to a device with a known, accurate standard to eliminate any variation in the device being checked is called calibration.
Calibration is a structured process designed to ensure measurement devices perform accurately and reliably. Each step in the process is crucial for maintaining operational consistency and compliance with industry standards.
Calibration is the process of comparing an instrument’s readings against a known reference standard to verify its accuracy. Its core purpose is simple: to ensure that measuring tools produce results you can trust.
According to ISA’s The Automation, Systems, and Instrumentation Dictionary, the word calibration is defined as “a test during which known values of measurand are applied to the transducer and corresponding output readings are recorded under specified conditions.”
Calibration is the process of adjusting and verifying the accuracy of a measuring instrument or system, such as an electronic device or sensor, to ensure that it provides the correct readings or outputs within the specified tolerance levels.
Calibration is the process of fine-tuning and verifying the accuracy of an instrument or device by comparing it against a known standard.
