What is re calibration definition?

Re calibration (short for "recalibration") is the process of adjusting and verifying the accuracy of an instrument or system that measures or detects a physical quantity. This is typically done periodically to ensure that the measurements or detections remain accurate and consistent over time. Re calibration may involve adjusting the instrument's internal settings or physical components, comparing its measurements against a known standard, and updating its calibration certificate or record. This process is important to avoid errors or discrepancies in measurements, which could have serious consequences in fields such as medical, aerospace, engineering, and manufacturing.
