A new measuring instrument for direct current

G. F. Gardner (nonmember; General Electric Company, Schenectady, N. Y.): Messrs. Corson and Faus have demonstrated again the advantages which accrue when the fundamental properties of a material are considered in laying out a new design. By abandoning the orthodox conception of appearance and size, they have started out along a fresh line of attack and the result has been a design which is not only well adapted for compact portable instruments, but one which will find ready adoption for incorporation in larger apparatus such as potentiometers and the like. Since space and weight, combined with good accuracy, are the outstanding problems in this larger type of instrument, their contribution will be appreciated by the designers of this type of equipment, who can thus make available to the user apparatus which is lighter and more compact without sacrifice of desirable characteristics.
