EFS 1001 Simplified Diagram) are designed to determine the relative strength of the electric field by comparing the level of the electric field on a known, stable, uncharged reference object. The object used in a field mill is known as the sensor plate. When an uncharged sensor plate is exposed to an electric field it becomes charged.
