Calibration surprisingly means different things to different people and it is important to understand what it means to you or the companies you request one from to ensure you are not disappointed with the end result. Calibration definition:
‘a set of operations that establish, under specified conditions, the relationship between the values of quantities indicated by a measuring instrument or measuring system … and the corresponding values realised by standards’
Therefore calibration is only the identification of current values against corresponding standardised values, made official within a calibration certificate.
Often the word ‘calibration’ is misused to describe the process of altering the performance of an instrument to ensure that the values it indicates are correct within specified limits. However, this is an additional part of the process referred to as adjustment.
Therefore if you send your instrument off for calibration in the hope to receive it back with corrected values, always ask for calibration and adjustment.
The IMC Group, however, always quotes calibration with adjustment, (where appropriate) so that we continue to meet the high expectations of our customer at all times.
