This specification provides the requirements for design, construction, performance, and testing of solid state bargraphtype indicating meters. The solid state bargraph meters covered by this specification are intended for use in shipboard applications of electrical measurement. This specification covers the requirements and quality assurance provisions for solid state, panel-type (edgewise), and rectangular switchboard-type instruments, which use light-emitting diodes (LEDs) for bargraph indication and optional digital displays. Bargraph meters shall be classified by type and style. The type designation defines the physical configuration of the meter and the scale. The style designation defines the meters display attributes as follows: bargraph display, and digital display. Meters shall be examined visually and mechanically to verify that materials, design, construction, physical dimensions, workmanship, and markings are as specified.
