Note(s)

  1. Attention is drawn to the notes immediately following the class title (G01).
  2. Measuring, by methods of general application, displacements, e.g. of the pointer of a measuring instrument, which are caused by variables of which the measurement is not covered by this sub-class, is dealt with in sub-class G01D.
  3. The groups of this sub-class 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.
  4. Machines operated on similar principles to the hand-held devices specified in this sub-class are classified with these devices.
