    bro check mo kung my ecg ka na libro or check mo sa alldatasheet pero base sa experience ko pag sa tv gamit pwede yan check mo lang ung pin nya ung kabila side ma check mo dun diode test. ngayun kung gusto mo malaman kung paano mag check ng opto coupler gamit ka ng 1.5 battery i connect mo sa diode side bale ung kabila side check mo sa meter mag kakaroon ng continuity pag nagkaroon ng continuity ung sa col/emmiter side buo ung opto coupler mo.
