摘要: A visual indicator includes a concave reflecting surface having an opening therein. An optical image-producing element moves into and out of the opening under the guidance of an electrical meter movement. The electrical meter movement responds to an electrical signal so that the image produced by the visual indicator is related to the magnitude of the electrical signal applied to the meter movement.
