This Standard applies both to analogue vernier callipers with a maximum measuring range f rom O to 2000 mm and a vernier
or circular scale graduated in 0,1,0,05 or 0,02 mm, and to vernier callipers with digitized outputover ranges from O up to a
maximum of 1000 mm in 0,01 mm incrementa.

2 Terminology
See DIN 2257 Parts 1 and 2 for concepts relating to dimensional metrology, and DIN 1319 Parts 1 to 4 for basic metrological
concepts.
