Calibration, in basic terms, is simply a comparison between two measurements. One of the measurements has a known correctness and the other measurement is that of the device you are testing. Calibration is needed to ensure that the known correctness measurement matches that of the test subject.
Ever since the days of the Industrial Revolution, the process of calibration has been improving. It’s extremely important that machines, instruments and devices are calibrated to ensure that products are assembled correctly and that measurements are taken correctly. Every type of industrial endeavor has need of calibration, whether you are creating packaging for a toy, building vehicle parts or even doing some type of medical testing.
Instruments need calibration on many occasions, not the least of which is before they are used for the first time. Most industries must have their equipment calibrated from time to time and receive calibration certification. In addition, calibration is needed if employees notice abnormalities or data inaccuracies. Calibration also is needed when any adjustments are made to the equipment. In addition, sometimes a machine might be jostled or moved and calibration will be needed to insure accuracy. Even a sudden change in weather or temperature can have an effect on certain pieces of equipment which will require calibration services.
There are several different types of instruments used for calibration, and each instrument takes a specific type of measurement. Some calibrators can perform multiple functions, and there are also black body calibrators, pressure calibrators, temperature probe calibrators and many more types.
Companies often outsource calibration services to companies with employees that are skilled in the art of calibration. The highly skilled individuals can calibrate and repair equipment as well as many kinds of instruments, including optical instruments, level instruments and more. Often these companies’ employees are called upon to help their customers obtain certification.
Calibration technician is the proper name of a person who performs these types of services and not only does it require several years of training from a technical school, you also have to have about five years of fieldwork before you can earn certification as a Certified Calibration Technician. However, many techs actually have four-year degrees or beyond in majors such as mechanical engineering or perhaps metrology, which is the study of measurements. If you become a calibration technician, you will learn how to use a variety of devices and calibrate all sorts of equipment, from optical devices to electrical equipment to perhaps even chemical equipment.
