Which certificate is issued by the LMB after calibration?

• A. Original Certificate of Instrument Registration
• B. Original Certificate of Instrument Calibration and Use
• C. Issued Certificate for Instrument Use
• D. Issued Certificate for Instrument Manual Registration

Answer: (A)

In calibration within the LMB system, the act of calibrating an instrument is paired with officially recording it in the instrument registry, making the instrument legally recognized for use in trade measurements. The certificate issued after this process is the Original Certificate of Instrument Registration. This document serves as the official record of the instrument’s identity, model, serial number, calibration date, and its approved status to be used in commerce. It provides proof that the instrument has been checked and registered with the authority.

The other options don’t fit because they describe certificates that do not correspond to the official post-calibration registration document. They imply use rights or different registration wording that isn’t the standard post-calibration certificate issued by the LMB.
