Abstract: This invention discloses a method and apparatus for accurately measuring and controlling the amount of power being absorbed by a load within the irradiating region of a diathermy applicator head. A desired power setting is initially preset into the diathermy apparatus. Thereafter, the diathermy apparatus is keyed on for a predetermined duty cycle causing RF energy to be generated within the applicator head during this time period. The level of power being absorbed by the load is then ascertained by measuring voltage and current flow in the head during the duty cycle. In the preferred embodiment of the invention, the electrostatic energy generated in the applicator head is attenuated by an electrostatic shield. Attenuation of the electrostatic energy improves the stability of the diathermy apparatus by significantly reducing electrostatic coupling between the applicator head and its attendant load.
