What Does calibration Mean
The concept of calibration refers to the act and consequence of calibrating , a verb with several meanings. Calibrating can consist of calculating or determining the gauge of an item; adjust an instrument relative to a reference; or value or estimate something.
Calibration, therefore, may lie in the comparison of the values obtained using a measuring instrument with the measurement that corresponds to a reference standard . In this way, the calibration of an instrument is carried out by appealing to another of greater precision that offers values that can be verified.
By comparing what the instrument under calibration indicates with the value of the reference standard, it is possible to know how accurate the artifact in question is. The higher the calibration frequency, the greater the accuracy of the measurements, since this process allows to develop the necessary adjustments.
Calibration is generally carried out under controlled conditions . This means that temperature , humidity and other variables are manipulated so that they do not affect the measurements.
There are many reasons that may make a calibration necessary. If an instrument's measurements are questionable, for example, calibration is a must. Calibration may also be unavoidable if the device has been subjected to a sudden or wide temperature change, if it has suffered a shock or if it has been used for a long time .
The scales , the micrometer , the dial gauges , the tachometers , the ammeter , the microscopes and thermometers are some of the devices to be subjected to calibration to remain reliable.
