"The face of the electropsychometer has a galvanometer that indicates changes in the person's resistance. According to Scientology doctrine, the resistance corresponds to the mental mass and energy of the subject's mind, which changes when the individual thinks of particular mental images or engrams (unconscious, painful memories)."
"These concepts are not validated by other scientists outside of Scientology; the action of the E-meter is more commonly attributed to galvanic skin response, an effect that is used in lie detectors."
Typically a microscopic, electrically conducting fiber (for example, silvered quartz) is suspended in a chamber, close to and connected with an insulated wire support where an electrostatic charge is applied, and similar charges deflect the fiber away from the support, the movement being monitored with a microscope and scale.
As the radiation of interest ionizes the enclosed gases, a slow discharge occurs, and the fiber retreats toward its resting position, the rate of movement indicating the intensity of the radiation.
An electroscope is an instrument for detecting the presence of electricity, or changes in the electric state of bodies, or the species of electricity present, by using pith balls, etc.
2. An instrument for measuring the deformation of metal under stress, or an instrument in which such deformation is used to register the elastic strains borne by other materials (e.g. concrete).
