DEFINITION

Classification: 324/227

Plural tests:

(under subclass 200) Subject matter wherein (1) two or more variable magnetic parameters are separately sensed and indicated, at least one of which is sensed and indicated by apparatus to sense and indicate the sensing of a magnetic field, or (2) at least one of two or more separate tests is a magnetic test.

(1) Note. The separate tests may be performed sequentially or simultaneously.

(2) Note. A. Subject matter of this subclass includes, for example, permeameters wherein a sensed voltage is used to indicate a change in flux for a given value of magnetomotive force indicated by the current causing the force. B. Subject matter of this subclass includes, for example, (1) a nonmagnetic hardness test combined with a magnetic flaw test, or (2) two simultaneous but spatially separated magnetic flaw tests.
