Description

칼라브라운관의 3극관 전류 자동측정 장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 본 발명에 따라 칼라브라운관의 3극관 전류를 자동으로 측정하는 장치를 도시한 도면.

Claims (1)

  1. 칼라브라운관(10)내의 제1그리드(2)에 소정시간동안 일정치의 전압(-45V)을 공급하는 제1전압공급부(60)를 연결하며, 소정시간 이후에는 제1그리드(2)와 캐소드(1)를 전기적으로 연결하는 자동 절환 스위치(SW)와, 상기 스위치(SW)에 의해서 제1그리드(2)에 제1전압공급부(60)에서 출력된 전압이 공급될때 캐소드(1)에 흐르는 전류가 일정치가 되도록 제2,3그리드(3)(4)에 공급되는 전압을 자동으로 조정하는 제2전압 공급부(70)와, 상기한 스위치(SW)의 접점 절환에 의해서 제1그리드(2)와 캐소드(1)가 전기적으로 연결된 상태에서 캐소드(1)에 흐르는 전류를 감지하여 디지탈화하는 A/D콘버터(20)와, 상기 A/D콘버터(20)에서 출력된 데이터를 표준데이터와 비교하여 칼라브라운관의 특성을 판별하는 수단으로 구성됨을 특징으로 하는 칼라브라운관의 3극관 전류 자동측정 장치.
