NOTES

  • 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.
