What assessors check
That each instrument in the equipment register has a current certificate, that the certificate is from an accredited provider for the relevant quantities, that the interval is justified, and that out-of-tolerance results were assessed for impact on past work.
Calibration certificates in AMPS
The AMPS shutdown case study lists equipment calibration forms among the documents tracked on the equipment page. AMPS keeps personnel and equipment certificates on dedicated personnel and equipment pages, and its flag system warns one month before a certificate, calibration document or scheduled inspection falls due, so managers always know what is missing or expiring. Documents saved through AMPS live in your own OneDrive, SharePoint or Google Drive, not on AMPS servers, so an existing QA folder structure keeps working unchanged and everything stays yours if you ever stop using AMPS.
