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 G 01.

(4)

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

Note

In groups G 01 B 5/00 to G 01 B 21/00, it is desirable to add the indexing codes of groups G 01 B 101:00 to G 01 B 121:00. The indexing codes should be unlinked. [6]
