To facilitate the testing and assembly of a measuring instrument necessary electronic and electrical components including meter 300 are mounted on printed-circuit board 400 so that the overall operation test of the instrument can be performed solely by testing this assembly mounted between cases 100, 200, upper case 100 having spring claws 108 engaging the meter. Line and earth probes 600, 700 are held by case 200 immovably in notches 110, 111. Optical guide 304 is shaped to transmit and spread light from lamp 405 across a meter scale plate.
