Calibration means how much error is the value represented by the measuring instrument compared to the standard value (standard instrument)? It refers to the work of confirming.
A gauge that describes the certification of items, size , measurement items, etc. is called a "calibration certificate".
In addition, the "Certificate of Traceability" consists of the following three certificates.
①
Certificate of traceability of reference instruments and measuring instruments (documents certifying that they are traceable (= traceable) to national standards)
②
Traceability system diagram (diagram that shows how the measuring instrument was calibrated and the route can be traced to the national standard)
③
Calibration records of reference instruments and measuring instruments (records of when and where maintenance of equipment is outsourced)
