          按鍵部分功能:

          P1.2:功能鍵

          p1.1:減

          p1.0:加

          p1.2按一下,開始設置液晶左下方00,然后可按鍵加減(00-20);

          p1.2再按一下,開始設置液晶第二個00,然后可按鍵加減(00-38);

          p1.2再按一下,開始設置液晶第三個參數(shù)0,然后可按鍵加減(0-8);

          p1.2再按一下,最后一位編程1,表示設置完成;

          可長時間按加減鍵,連續(xù)加減;

          以上操作可重復。
