Calibration
Calibration is the process through which instruments are adjusted to match accepted measurement standards. Calibration ensures precision. As accuracy is essential to the performance of measurement tools and devices in many industries, regular calibration is necessary to maintain quality standards.
Calibrating instruments measure the reading or output of a device and compare it to accepted standards. Once the margin of error has been decided, the device can be adjusted to values identical with the standard.
Numerous sources are available that contain standardized values for the comparison of materials and components. In the United States, the National Institute of Standards and Technology is the most definitive source on measurement standards. Some instruments that require regular calibration include scales, thermometers, speedometers, commercial ovens, lasers, and various gauges.
