Benefits of Calibration
To maintain your measurement accuracy, it is recommended that you calibrate your measurement devices at least annually. DefinitionsNIST: U.S. National Institute of Standards & Technology Calibration is simply the process of comparing the unknown with a reference standard and reporting the results. For Example: Applied= 1.3V, Indicated=1.26V (or Error =-0.04V) Calibration may include adjustment to correct any deviation from the value of the standard. Verification, as it related to calibration, is the comparison of the results against a specification, usually the manufacturer's published performance figures for the product. (e.g. Error=-0.04V, Spec=±0.03V, "FAIL"). Some calibration labs include a specification status statement on their Certificate of Calibration. (ie the did/did not comply with a particular spec). Conformance, especially regarding the meaning of a Certificate of Conformance. Typically available when an instrument is purchased, it is generally recognized that such a document has little value as an assurance of product performance. Of course, the manufacturer expects that the product conforms to its specifications but, in this sense, the document simply affirms that the customer's purchase order/contract requirement has been duly fulfilled.
