FEATURES OF TESTING OF THE BUILT-IN SOFTWARE OF MEASURING INSTRUMENTS

Protection against unauthorized modification or its components, measurement data and protection against external unintentional and accidental interference are particularly important for measuring instruments (MIs) software. The possibilities of ensuring the security of built-in MI software, as well as MI as a whole, are considered. The analysis of the main features of built-in MI software on the basis of documents, guidelines and recommendations of international and regional organizations in the field of legal metrology are shown. The characteristics of MI software in accordance with international and regional documents, guidelines and recommendations are the establishment and regulation of such tests, which must be provided in the testing methods for specific MI with embedded software.
