Through the courtesy of the General Electric Company,I have obtained the latest instructions for reading theelectric kilowatt hour or watt hour meter, which I amsure will prove interesting and instructive. Before proceeding with the directions, I wish to callyour attention to Figs. 36 and 37, illustrating the exteriorand the interior of the Thomson watt hour MOTION PICTURE ELECTRICITY SI DIRECTIONS First—Note carefully the unit in which the dials all meters made by the General Electric Company,the figures above or below the dials indicate the value ofone complete revolution of the pointer, therefore one di-vision indicates one-tenth of the amount marked aboveor below. Second — Note di-rection of rotation ofdial pointers. Count-ing from the right thepointers of the first,third and fifth dials ofthe General ElectricCompanys meters ro-tate in the direction ofthe hands of a watch,whereas the pointersof the second andfourth dials move inthe opposite direction. Third -— Read dialsfrom right to left, set-ting down figures asread. Fourth—A 1 w a y sread the figure oneach dial which hasbeen last passed or isjust covered by the pointer.
