Purpose of CalibrationPurpose of Calibration

To ensure readings from an instrument are consistent To ensure readings from an instrument are consistent with other instruments and to determine the accuracy with other instruments and to determine the accuracy of the instrument i.e. that it can be trusted for its of the instrument i.e. that it can be trusted for its observed/displayed measured value.observed/displayed measured value.

The value of calibration for industry To ensure that products are manufactured to specifications. To demonstrate that the industry operates a quality system

and technically competent and are able to generate technically valid results.

To increase quality & value of product. The calibrated measuring instruments (working standards)

have the assurance of an unbroken chain of national/international measuring standards.
