Calibration is the process of comparing a measurement instrument against a verified standard instrument. It checks the parameters of an artifact, instrument, or system by comparing it against measurement standards. Adjustment of the measurement is the part of a calibration to agree with
value of the applied standard, but it’s not necessary. A calibration process generally assures that a system or device will produce results which meet or exceed some defined criteria with a specified degree of confidence.
Sometimes it happens that the results will exhibit random statistical fluctuations which may or may not be significant. This is mainly caused when a measurement is repeated many times. These are systematic errors and which are offsets from the true value of a parameter and corrections are generally applied, eliminating their effect on the calibration. If they are not found, they can have an undesirable effect on the accuracy of the calibration. High-accuracy calibrations are usually accompanied by an analysis of the sources of error and a statement of the uncertainty of the calibration.
Calibration is used to check the accuracy of measurement of instruments like thermometer, Incubators & Freezers, thermo cycler, temperature Controllers and several electronics instruments. In computing, an interactive white board and other input method can be calibrated so that relation between the physical pen position and the position of the cursor on the screen is established and properly
adjusted.
