預付費電表在安裝的時候位置應保持垂直，并參照接線圖接入。

2. 將預購(gou)電(dian)(dian)量IC卡（金屬觸(chu)點面向左）插(cha)入表內，顯(xian)(xian)示(shi)屏首先顯(xian)(xian)示(shi)F1然后(hou)顯(xian)(xian)示(shi)本次所購(gou)電(dian)(dian)量數值(zhi)，再穩定顯(xian)(xian)示(shi)F2后(hou)顯(xian)(xian)示(shi)屏顯(xian)(xian)示(shi)原(yuan)剩(sheng)余電(dian)(dian)量加上新(xin)購(gou)電(dian)(dian)量總和為當前剩(sheng)余的電(dian)(dian)量值(zhi)，此時就可以(yi)取下IC卡，顯(xian)(xian)示(shi)屏熄滅。

4. 預付費電(dian)(dian)(dian)能表(biao)在(zai)正常使(shi)用過程(cheng)中，會自動對所購電(dian)(dian)(dian)量(liang)(liang)作遞減(jian)計算。當電(dian)(dian)(dian)能表(biao)內剩余(yu)電(dian)(dian)(dian)量(liang)(liang)小(xiao)于20度時(shi)，顯示(shi)屏(ping)顯示(shi)當前剩余(yu)電(dian)(dian)(dian)量(liang)(liang)，從而提醒用戶購電(dian)(dian)(dian)；當剩余(yu)電(dian)(dian)(dian)量(liang)(liang)等(deng)于10度時(shi)，停電(dian)(dian)(dian)一次提醒用戶購電(dian)(dian)(dian)，此(ci)時(shi)用戶需將IC卡插入(ru)電(dian)(dian)(dian)能表(biao)一次恢復供電(dian)(dian)(dian)。當剩余(yu)電(dian)(dian)(dian)量(liang)(liang)為零時(shi)，將停止供電(dian)(dian)(dian)。

6. 預(yu)付費電能表(biao)顯示(shi)(shi)器(qi)通常不亮(liang)，如用戶(hu)需(xu)要(yao)檢查剩余電量(liang)時，可以將IC卡(ka)插入(ru)電表(biao)卡(ka)槽內，則顯示(shi)(shi)F1購(gou)買電量(liang)顯示(shi)(shi)零、F2剩余電量(liang)，拔(ba)卡(ka)顯示(shi)(shi)屏熄滅。

7. 用(yong)(yong)(yong)(yong)戶(hu)(hu)每次將(jiang)IC卡插入預(yu)付費電(dian)(dian)(dian)(dian)能表卡槽內，電(dian)(dian)(dian)(dian)能表都會將(jiang)用(yong)(yong)(yong)(yong)戶(hu)(hu)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)情況全部(bu)返寫在IC卡上，下次購電(dian)(dian)(dian)(dian)時(shi)，售電(dian)(dian)(dian)(dian)管理系統可(ke)以(yi)(yi)讀取(qu)IC卡數(shu)據，并(bing)檢(jian)查該用(yong)(yong)(yong)(yong)戶(hu)(hu)是否合法用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)。用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)檢(jian)查人員(yuan)也可(ke)以(yi)(yi)使用(yong)(yong)(yong)(yong)檢(jian)查卡，檢(jian)查用(yong)(yong)(yong)(yong)戶(hu)(hu)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)情況。
