DEFINITION

Classification: 324/90

(under subclass 83) Subject matter having an indicating instrument of the type which has a stator element which produces a magnetic field by means of a supplied current.

(1) Note. The electrodynamometer instruments usually do not have a permanent magnetic field, but not necessarily so. They are, for example, of the ratio-meter type.
