style="text-indent:25px">顯示位數(shù)：這直接關(guān)系到數(shù)顯表的測(cè)量精度，一般來(lái)講，顯示位數(shù)越高，測(cè)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(jiàn)于計(jì)數(shù)器、累計(jì)表和**儀表)，用戶可以根據(jù)測(cè)量精度要求來(lái)選擇幾位的數(shù)顯表。輸入信號(hào)：指直接輸入儀表的測(cè)量信號(hào)，有些工業(yè)信號(hào)是直接接入儀表測(cè)量的，有些信號(hào)是經(jīng)過(guò)轉(zhuǎn)化后接入儀表的，必須弄清楚測(cè)量信號(hào)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(hào)類型：電流還是電壓，交流還是直流，是脈沖信號(hào)還是線性信號(hào)等等，還要弄清信號(hào)的大小。</p><p style="text-indent:25px">常見(jiàn)問(wèn)題：通電后缺筆或顯示亂碼可能原因：缺筆基本上為虛焊問(wèn)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(duì)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(jiàn)問(wèn)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(duì)是否一致;電壓、電流的額定值是否一致。</p><div

style="text-indent:25px">數(shù)顯儀表產(chǎn)生干擾的途徑：信號(hào)源與儀表之間的導(dǎo)線、內(nèi)部配線通過(guò)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(chǎng)，而閉合回路處在這種變化的磁場(chǎng)中將產(chǎn)生電動(dòng)勢(shì)。這種感應(yīng)電勢(shì)與有用信號(hào)串聯(lián)，當(dāng)傳感器與數(shù)顯表距離較遠(yuǎn)時(shí)，這種串模干擾特別突出。干擾源通過(guò)電容的耦合在回路中形成干擾，是由于兩電場(chǎng)相互作用的結(jié)果。通過(guò)靜電耦合的方式，能在兩輸入端感應(yīng)出對(duì)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(hào)相疊加，它不直接對(duì)儀表產(chǎn)生影響。但它能通過(guò)測(cè)量系統(tǒng)形成到地的泄漏電流，該泄漏電流通過(guò)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(huì)產(chǎn)生諧波干擾。達(dá)州數(shù)顯儀表哪家好</p><p
