Equipment Calibration
Equipment calibration is the process through which pieces of equipment are adjusted for precision. As machinery in many industries requires precision and accuracy of all components in order to continue working properly, regular calibration of equipment is necessary. Some examples of instruments that require regular calibration are: speedometers, thermometers, scales, commercial ovens, lasers, and various other gauges.
Calibrating instruments measure the reading or output of a device and compare it to the standard it is designed to match. When a margin of error is discovered, adjustments or repairs can be made to make the component's output identical to the established industrial standard.
Many sources are available that list standardized values and precision levels for materials and components of electronic instruments. In the United States, the National Institute of Standards and Technology is the authority on measurement standards.
