Notes

(1)This subclass covers measuring of position or displacement in terms of linear or angular dimensions.  [4]

(2)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.

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

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