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(shí)會(huì)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(shí)儀表會(huì)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">模擬顯示儀表通常只能接受標(biāo)準(zhǔn)信號（如4~20mA）或選擇一種輸入信號如鉑熱電阻或熱電偶等，儀表刻度范圍不能靈活改變；而智能數(shù)字顯示儀表可接受多種輸入信號，通過簡單的組態(tài)就可以接受直流毫伏、伏、毫安、熱電偶、熱電阻、標(biāo)準(zhǔn)信號等，設(shè)定測量范圍、刻度范圍靈活方便。智能數(shù)字顯示儀表的讀數(shù)方便，無視差；智能數(shù)字顯示儀表的顯示準(zhǔn)確度能達(dá)到滿量程的±0.05%+2個(gè)字，記錄準(zhǔn)確度為滿量程的±0.1%，而模擬顯示儀表一般*為滿量程的±0.5%。</p><div

style="text-indent:25px">智能數(shù)字顯示儀表既有模擬記錄儀的趨勢記錄，又有表格式記錄，還具有記錄曲線零點(diǎn)遷移（即量程自動(dòng)切換）、分區(qū)記錄、放大/縮小記錄等功能，測量和記錄速度很高，各通道記錄曲線在時(shí)間上可以一致。而模擬記錄儀的功能單一，只能記錄趨勢曲線，記錄響應(yīng)速度也慢。由于智能數(shù)字顯示儀表采用了微處理器，所以它有運(yùn)算功能，除四則運(yùn)算外，還有開方、***值、平均值、邏輯運(yùn)算等，以及異常情況自動(dòng)顯示記錄。所有這些都是模擬顯示儀表無法比擬的。樂山數(shù)顯儀表哪家好</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(jià)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(jì)數(shù)器、累計(jì)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。樂山數(shù)顯儀表哪家好</p><p
