一、多功能電表故障分析處理

1、顯示器不顯，當電源電路經變壓器降壓方(fang)式(shi)供(gong)電時(shi)，可能存在的(de)故障緣由有：

② 因變(bian)壓器繞組泛(fan)起斷(duan)線或匝間短(duan)路對變(bian)壓器燒壞，造成顯(xian)示(shi)器不顯(xian)示(shi)。處(chu)置方式：更換同規格的變(bian)壓器。

④ 當電(dian)源電(dian)路經(jing)阻容降壓方式供電(dian)時，電(dian)容擊(ji)穿可(ke)造成顯示器(qi)不顯示。處置方式：更換電(dian)容。

⑤ 當電源電路(lu)經過程(cheng)開(kai)關電源的降(jiang)壓方(fang)(fang)式(shi)供電時，穩(wen)壓管壞可造成顯示器不顯示。處置方(fang)(fang)式(shi)：更(geng)換穩(wen)壓管。

2、數(shu)據(ju)(ju)或(huo)法(fa)(fa)式(shi)丟失，多(duo)功能(neng)(neng)(neng)電(dian)(dian)(dian)表(biao)在(zai)斷(duan)電(dian)(dian)(dian)時主要由(you)后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)來(lai)維持時鐘及(ji)(ji)一些寄存(cun)在(zai)RAM里的(de)(de)法(fa)(fa)式(shi)及(ji)(ji)數(shu)據(ju)(ju)。后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)系統(tong)由(you)鋰電(dian)(dian)(dian)池（一般(ban)一節鋰電(dian)(dian)(dian)池在(zai)斷(duan)電(dian)(dian)(dian)后(hou)可(ke)連(lian)結法(fa)(fa)式(shi)和(he)數(shu)據(ju)(ju)的(de)(de)時間少則(ze)半年(nian)，多(duo)則(ze)五年(nian)）和(he)儲(chu)能(neng)(neng)(neng)電(dian)(dian)(dian)容(rong)(rong)(rong)組(zu)成，有(you)(you)(you)的(de)(de)僅(jin)有(you)(you)(you)鋰電(dian)(dian)(dian)池或(huo)儲(chu)能(neng)(neng)(neng)電(dian)(dian)(dian)容(rong)(rong)(rong)。假(jia)設全電(dian)(dian)(dian)子多(duo)功能(neng)(neng)(neng)電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)的(de)(de)年(nian)夜量數(shu)據(ju)(ju)及(ji)(ji)法(fa)(fa)式(shi)存(cun)儲(chu)于E2PROM中(zhong)，斷(duan)電(dian)(dian)(dian)時可(ke)無需(xu)消耗后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)，后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)僅(jin)提供(gong)給時鐘電(dian)(dian)(dian)路，因而(er)消耗后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)容(rong)(rong)(rong)量很小。若將(jiang)全電(dian)(dian)(dian)子多(duo)功能(neng)(neng)(neng)電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)的(de)(de)數(shu)據(ju)(ju)存(cun)儲(chu)于RAM中(zhong)，則(ze)需(xu)要有(you)(you)(you)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)維持才能(neng)(neng)(neng)保留數(shu)據(ju)(ju)，長時中(zhong)斷(duan)電(dian)(dian)(dian)很快(kuai)就會耗盡電(dian)(dian)(dian)池容(rong)(rong)(rong)量，從而(er)造(zao)成數(shu)據(ju)(ju)和(he)法(fa)(fa)式(shi)丟失。由(you)后(hou)備(bei)(bei)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)引發數(shu)據(ju)(ju)、法(fa)(fa)式(shi)丟失的(de)(de)常見(jian)故障有(you)(you)(you)：

② 儲能(neng)電(dian)容(rong)漏電(dian)，以致停電(dian)時(shi)將(jiang)數據、法(fa)式丟失。處置(zhi)方式：更換電(dian)容(rong)。

④ 電(dian)池(chi)毗連線短路放(fang)電(dian)，耗盡電(dian)池(chi)，使法(fa)式、數據丟失。處置(zhi)方式：消除(chu)短路，更換電(dian)池(chi)。
