Measuring instruments: track in-service verification
France and Switzerland require legal-metrology checks to be examined by instrument category and regulated use. Identify the actual device, location and verification records. Initial market conformity, subsequent verification and maintenance are different stages. The register records documented requirements and interventions without inventing a single verification interval or treating servicing as proof of every mandatory control.
