Calibration is the process of measuring or adjusting the accuracy or precision of a piece of equipment, instrument, or system. It involves comparing the measurement or output of the device being calibrated to a known standard or reference value. The purpose of calibration is to ensure that the device provides accurate and reliable measurements or outputs within specified tolerances.
Calibration is commonly performed to set or correct the device's output to match the desired or expected values. This process involves making adjustments to the device's settings, controls, or internal components to align its measurements or outputs with the established standard. In some cases, calibration may involve a simple adjustment, such as turning a dial or knob, while in others it may require more complex procedures or the use of specialized calibration tools.
Calibration is essential in various fields and industries to maintain and validate the accuracy and performance of equipment. This includes areas such as manufacturing, laboratory testing, engineering, scientific research, healthcare, and more. Regular calibration helps ensure that measurements and outputs are consistent, reliable, and traceable to recognized standards.
The results of calibration are often documented in a calibration certificate or report, which provides information about the equipment, calibration procedure, standards used, and the deviation or adjustments made. These records are crucial for quality control, compliance with regulations, and demonstrating the reliability of the calibrated device.

The word "calibration" comes from the Latin word "calibrare", which means "to level, to make even". It is derived from the Latin term "calx", meaning "limestone", which was used in ancient times to make a "calx", a small ledge used in weighing scales to balance the weights. Over time, the term evolved and expanded to refer to the process of adjusting and standardizing the accuracy of measuring instruments and equipment.
