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、電力線的周圍空間都存在有很強的交流磁場，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、帶整流子的電機等會產(chǎn)生諧波干擾。四川數(shù)顯儀表價格</p><div

可能原因：信號未輸入儀表解決方法：測試儀表接線端子有無信號，端子連接是否可靠。常見問題：三相儀表缺相可能原因：信號未加到儀表上解決方法：測試接線端子有無輸入信號，端子是否正確可靠連接;可將正常顯示的一相信號線接到缺相信號進行對比測試。常見問題：電能計量不準(zhǔn) 可能原因：變比不對，電壓電流的相序錯誤解決方法：將儀表設(shè)置的變比與PT、CT的變比核對是否一致;檢查電壓、電流的相序是否正確;在用電情況下，有功率顯示的儀表可以通過儀表的功率顯示查看單相功率是否有負號指示，有負號指示的則很可能對應(yīng)的那相電流的進出線反了。</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)確度能達到滿量程的±0.05%+2個字，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
