Note(s)
This subclass covers measuring of position or displacement in terms of linear or angular dimensions.[4]In this subclass, the groups are distinguished by the measurement technique which is of major importance. Thus the mere application of other techniques or 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.
