What is calibration?

Calibration is defined as an association between measurements – one of a scale or accuracy made or set with one piece of equipment and another measurement made in as similar a way as possible with a second piece of equipment. The piece of equipment or device with the known or assigned accuracy is called the standard.

The process of comparing a measurement instrument against a verified standard instrument

Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.The formal definition of calibration by the International Bureau of Weights and Measures is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication.

Calibration is the setting or correcting of a measuring device usually by adjusting it to match or conform to a dependably known and unvarying measure.

Calibration must be done for each and every measuring device in food industry in order to make sure that these devices are performing well and the results obtained form them are reliable. 

The adjustment (by comparison with a standard) of the accuracy of a measuring instrument. 

Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range.  Eliminating or minimizing factors that cause inaccurate measurements is a fundamental aspect of instrumentation design.

Calibration is the type of process to make an adjustment to have an accurate result of measurenent per unit.

Calibration refers to the process of determining the relation between the output (or response) of a measuring instrument and the value of the input quantity or attribute, a measurement standard. In non-specialized use, calibration is often regarded as including the process of adjusting the output or indication on a measurement instrument to agree with value of the applied standard, within a specified accuracy. For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted (e.g. via calibration constants) so that it shows the true temperature in Celsius at specific points on the scale. Calibration also can refer to judgments made by a prognosticator, for example, a weather-forecaster who states that "there is an80% chance of rain today," if properly calibrated, will say this on precisely80% of the days during which it rains.
