NOTE
-
This subclass covers measuring of position or displacement in terms of linear or angular dimensions.

In this subclass, the groups are distinguished by the means of measurement which is of major importance. Thus the mere application of other means for giving a final indication does not affect the classification.

Attention is drawn to the Notes following the title of class G01.

Machines operated on similar principles to the hand-held devices specified in this subclass are classified with these devices.

Measuring arrangements or details thereof covered by two or more of groups G01B 3/00 - G01B 17/00 are classified in group G01B 21/00 if no single other group can be selected as being predominantly applicable.
