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。攀枝花數(shù)顯儀表廠家</p><div

style="text-indent:25px">常見問題：通電后不顯示可能原因：輔助電源未加到儀表上;電源變壓器或開關(guān)電源故障解決方法：使用萬用表檢查輔助電源接線，查看是否具有相應(yīng)的工作電壓;如有相應(yīng)電壓，則儀表內(nèi)部電源或線路出現(xiàn)故障，可聯(lián)系廠家調(diào)換。常見問題：數(shù)碼管亮但顯示為零可能原因：未輸入信號解決方法：查輸入信號接線是否正確并用信號輸入，無則客戶自查;有則初判表故障(可能：測量芯片管腳或數(shù)碼管管腳虛焊)，可聯(lián)系廠家調(diào)換。常見問題：通電后閃爍可能原因：1)信號不穩(wěn)定;2)有強磁場干擾源3)表故障：線圈故障，芯片虛焊等原因。解決方法：按國標(biāo)要求，顯示值允許有2 - 3字的跳動，但不允許間隔跳。斷開輔助電源;測試其是否超出工作電壓范圍;測試輸入信號是否超出額定值;測試環(huán)境溫度是否超出使用上限;測試并解決問題后將輔助電源重新上電。</p><p style="text-indent:25px">顯示位數(shù)：這直接關(guān)系到數(shù)顯表的測量精度，一般來講，顯示位數(shù)越高，測量更準(zhǔn)確，價格也越貴，主要有以下幾種：兩位;三位;三位半;四位;四位半;四又四分之三；五位及五位以上(常見于計數(shù)器、累計表和**儀表)，用戶可以根據(jù)測量精度要求來選擇幾位的數(shù)顯表。輸入信號：指直接輸入儀表的測量信號，有些工業(yè)信號是直接接入儀表測量的，有些信號是經(jīng)過轉(zhuǎn)化后接入儀表的，必須弄清楚測量信號的性質(zhì)，否則買去的儀表不能用，甚至損壞儀表及原有設(shè)備。要弄清信號類型：電流還是電壓，交流還是直流，是脈沖信號還是線性信號等等，還要弄清信號的大小。</p><div
