Abstract

본 발명은 다기능 전력수급용 복합계기의 LCD자기체크모드에 관한 것으로, 테스트 포트의 접점을 온시켜 LCD자기 체크의 모드를 선택하면, 승률모드를 3초동안 표시하도록 하고, 디스플레이 스위치가 온되면 세그먼트를 1개씩 수동점멸시키고, 디스플레이 스위치가 온되지 않으면 전표시 세그먼트를 순차적으로 점멸시킨 후, 정전의 상태인가를 확인하여 정전 상태표시로 고정하거나, LCD자기 체크의 모드를 해제할 때까지 전표시 세그먼트를 고정점등시키는 과정에 의해 수행하도록 함으로써 LCD의 세그먼트의 정상여부를 확인할 수 있도록 한 것이다.The present invention relates to an LCD magnetic check mode of a multi-function power supply-type multi-function meter. When the contact of the test port is turned on and the LCD magnetic check mode is selected, the multiplier mode is displayed for 3 seconds and the display switch is turned on. If the display switch is not turned on one by one, and all display segments are blinking sequentially, after confirming whether the state of power failure, fix it to the power failure status display or all display segments until the LCD self-check mode is released. By performing the process of fixed lighting, it is possible to check the normality of the segment of the LCD.

제1도는 본 발명의 개략적인 구성을 나타낸 블럭도, 제2도는 본 발명의 동작과정을 나타낸 플로우챠트.1 is a block diagram showing a schematic configuration of the present invention, Figure 2 is a flow chart showing the operation of the present invention.

Claims (1)

테스트 포트(14)를 이용하여 LCD 자기체크의 모드를 선택하면 합성변성비배를 3초동안 표시하는 승률모드를 수행하는 단계와, 3초가 경과하면 디스플레이 스위치(SW1)가 온되었는가를 확인하는 단계와, 디스플레이 스위치가 온되었으면 세그먼트를 1개씩 수동점멸하고 온되지 않았으면 전표시 세그먼트를 순차적으로 점멸시키는 단계와, 통전상태가 계속유지되면 LCD자기체크의 모드가 종료될때 까지 전표시 세그먼트를 고정 점등시키는 단계들에 의해 수행됨을 특징으로 하는 다기능 전력수급용 복합계기의 LCD 자기 체크방법.Selecting a mode of the LCD magnetic check using the test port 14, performing a multiplier mode for displaying the composite denaturation ratio for 3 seconds; checking whether the display switch SW1 is on after 3 seconds; If the display switch is on, manual segment flashes one by one, and if not, flashes all display segments sequentially.If the display state is maintained, all display segments are fixedly lit until the LCD self-check mode is finished. LCD self-checking method of the multi-function power supply multi-function instrument characterized in that performed by the steps. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
