.~ With temperature control of material or element of test circuit
DEFINITION
Classification: 324/224
With temperature control of material or element of test circuit:
(under subclass 200) Subject matter wherein the apparatus to sense and indicate the sensing of a magnetic field is also responsive to magnetic fields modified by tested materials placed in a magnetic field and includes means to control the temperature of the material tested or some element of the apparatus to sense and indicate the sensing of the magnetic field.
(1) Note. The means to control the temperature includes heating and cooling.
