When were your calipers last recertified? Can you post a pictured of them zeroed?

[–] JubJubBird@sh.itjust.works 3 points 2 weeks ago (1 children)

Here you go. I took it at 21°C. 1023 hPa. 80% humidity. 9.81104 g.

And the cert? And what's the traceability?

I took the picture in 2023 right after the certificate guy handed me this. I didnt catch his name though. The quality of the copper is the same as it was back then.
