Calibration

Calibration of a measurement instrument or apparatus is adjusted to give accurate results.
Calibration result, the extent / scale, the failure of the measuring instrument or measuring system of shorthand, or ordinary enables the given value to the signs of a scale.
The calibration process can also determine other metrological properties.
Calibration results, calibration certificate or calibration report given name can be saved with a document.

Sometimes resulting calibration, a calibration factor or calibration curve in the form of an array can be expressed as a calibration factor.

In the calibration process, the amount of error of calibrated measuring instruments, higher accuracy itself (at least 3 times), determined by reference to a meter. Calibration of measuring instruments referenced (s) over in the calibration certificate must be traceable to national or international basic reference. Thus, the calibrated measuring instruments will be provided traceability to fundamental reference.

The calibration process is an experimental study, all requirements expected from the experimental work must be met. So working in a controlled environment, attentive and trained with written work habits persons should be done, it is done by setting features work, the equipment used, methods, measurement uncertainty, and the results should be mentioned in the calibration report.
The error of the calibration results of measuring instruments, or if you have used this process error has been determined to be outside the limits specified in the relevant standard setting is attempted to be resolved. However, after setting the calibration must be repeated and reported the latest situation.

Measuring instruments, measuring principle and as they age over time depending on usage conditions and technologies, therefore the calibration must be repeated in certain periods. The said period shall be determined by taking into account device characteristics and operating conditions experienced by users.

Calibration, why it is an expectation of quality management systems, is because of a need for businesses. If there is a need to measure the size of the company, to determine whether there are doing the required accuracy of measuring instruments used in the measurement are also needed.
