calibration
Instrument calibration is one of the first steps to maintain the accuracy of instrumentation equipment. The process of setting up an equipment to obtain the result of work in a certain range, for example, is called calibration. Eliminating or minimizing the factors that reduce the accuracy of an equipment is one of the most important steps in the design of instrumentation equipment, which is achieved by instrument calibration equipment.
Although the calibration method differs from one product to another, it generally involves the use of precision instruments to test one or more of the sample values called calibrators.The results of this test are used to make a connection between the measurement technique used in the instrument and the values or factors being tested. After this test, we can be sure that the instrument can work well in the face of unknown values or factors other than the sample factors.
