style="text-indent:25px">常見問題：通電后缺筆或顯示亂碼可能原因：缺筆基本上為虛焊問題。直接換表。亂碼：1.有干擾源，如大容量開關(guān)合閘時會造成對儀表的沖擊，使多功能表進(jìn)入設(shè)置界面，而非亂碼。此時儀表會在30秒內(nèi)恢復(fù)，或按SET恢復(fù)正常。2.芯片故障：芯片故障率一般為千分之一以下;3.芯片虛焊或漏焊。解決方法：前者與客戶溝通，不成，換表(在電源前端作相應(yīng)處理)，后二都直接換表。常見問題：顯示不準(zhǔn)確可能原因：互感器變比設(shè)置數(shù)值不匹配解決方法：將儀表設(shè)置的變比與PT、CT的變比核對是否一致;電壓、電流的額定值是否一致。</p><p style="text-indent:25px">數(shù)顯儀表產(chǎn)生干擾的途徑：信號源與儀表之間的導(dǎo)線、內(nèi)部配線通過磁耦合在電路中形成干擾。在大功率變壓器、交流電機(jī)、電力線的周圍空間都存在有很強(qiáng)的交流磁場，而閉合回路處在這種變化的磁場中將產(chǎn)生電動勢。這種感應(yīng)電勢與有用信號串聯(lián)，當(dāng)傳感器與數(shù)顯表距離較遠(yuǎn)時，這種串模干擾特別突出。干擾源通過電容的耦合在回路中形成干擾，是由于兩電場相互作用的結(jié)果。通過靜電耦合的方式，能在兩輸入端感應(yīng)出對地的共同電壓，以共模干擾的形式出現(xiàn)，由于共模干擾不和信號相疊加，它不直接對儀表產(chǎn)生影響。但它能通過測量系統(tǒng)形成到地的泄漏電流，該泄漏電流通過電阻的耦合就能直接作用于儀表而產(chǎn)生干擾。電磁感應(yīng)、靜電感應(yīng)所形成大多是工頻干擾電壓，但變頻器、帶整流子的電機(jī)等會產(chǎn)生諧波干擾。</p><div
