Abstract
A knowledge of the performance of electrical instruments in the presence of magnetic fields is of importance to their intelligent use. The present paper describes: a study of this problem as applied to portable voltmeters, ammeters and wattmeters; and a brief survey of such magnetic fields as might be found around certain laboratory or small-plant equipment. Only portable direct -and 60-cycle a-c instruments were studied; panel-and switchboard-type instruments, presenting problems of their own were not included.
