Lenz），C：電容(Capacitor)，R：電阻(Resistance)，LCR數(shù)字電橋就是能夠測量電感，電容，電阻，阻抗的儀器，這是一個傳統(tǒng)習慣的說法，較早的阻抗測量用的是真正的電橋方法，隨著現(xiàn)代模擬和數(shù)字技術的發(fā)展，早已經(jīng)淘汰了這種測量方法，山東電橋lcr系統(tǒng)，但LCR電橋的叫法一直沿用至今。如果是使用了微處理器的LCR電橋則叫LCR數(shù)字電橋。一般用戶又稱這些為：LCR測試儀、LCR電橋，山東電橋lcr系統(tǒng)、LCR表、數(shù)字電橋，山東電橋lcr系統(tǒng)、LCR Meter等等。圳市展榮新精密電子有限公司，專業(yè)從事電子變壓器、電感線圈、電容電阻等各類元器件測試儀之自主研發(fā)、制造和銷售。現(xiàn)有的主要產(chǎn)品—電子變壓器綜合測試系統(tǒng)、精密LCR數(shù)字電橋和直流微電阻表等，并代理國內(nèi)外**品牌的測量儀表。早期的LCR測試就是一個真正的電橋平衡測試方法。山東電橋lcr系統(tǒng)</p><div

style="text-indent:25px">在使用LCR數(shù)字電橋時要注意儀器應在技術指標規(guī)定的環(huán)境中工作,儀器特別是連接試件的測試導線應遠離強電磁場,以免對測量產(chǎn)生干擾.測試完畢或排除故障時需打開儀器時,應將電源開關置于OFF位置并拔下電源插頭.儀器測試夾具或測試電纜應保持清潔,備測試件引腳應保持清潔,以保證試件接觸良好.LCR數(shù)字電橋?qū)嶋H電感、電容、電阻并非理想的純電抗或電阻元件,而是以串聯(lián)或并聯(lián)形式呈現(xiàn)為一個復阻抗元件,本儀器根據(jù)串聯(lián)或并聯(lián)等效電路來計算其所需值,不同等效電路將得到不同的結果.山東電橋lcr系統(tǒng)lcr電橋中L是電感(Inductance), R是電阻(Resistance），C是電容(Capacitance）。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東電橋lcr系統(tǒng),lcr"

style="text-indent:25px">在振動式料位開關研發(fā)中，一般通過LCR數(shù)字電橋來準確測量壓電陶瓷的電容值。通常壓電陶瓷的電容值會受擠壓影響而變化，為減少測量誤差，應設計一個壓電陶瓷夾具（如上圖所示），然后用電橋電纜兩個夾子夾住自制夾具的兩個電極，將壓電陶瓷放入夾具的兩個銅片中來測量。壓電陶瓷的靜態(tài)電容測量中，測量結果還與測量環(huán)境密切相關，特別是環(huán)境濕度和空氣流動，這導致儀表顯示結果往往極不穩(wěn)定，電橋顯示的電容值處于變化跳動狀態(tài)，隨后數(shù)值跳動頻率變小，直到數(shù)值變化很緩，且數(shù)值時大時小變化。</p><p style="text-indent:25px">作為一個新用戶，怎樣選擇一款lcr數(shù)字電橋？首先是看儀器的測試準確度，看儀器的測試頻率，看儀器的測試電平。儀器的輸出阻抗或稱內(nèi)阻。其他視客戶使用具體情況而定，或者可以根據(jù)客戶的實際情況向同深圳市展榮新精密電子有限公司技術咨詢。對于一個已知的“電容”，客戶該選用什么樣的測試條件?1.小于100pF電容用1MHZ頻率測量，中等容量如(1000pF-10uF)用1KHZ,10KHZ,100KHZ，國家標準測試中等電容的測試頻率標準是1KHZ。電解類如鋁電解，鉭電解等用100HZ或120HZ。2.從電平的角度說大部分電容對電平不敏感，不同電平測試變化不大，但有些介電常數(shù)大的電容與電平非常敏感，應仔細選擇電平。通過本文的介紹，相信大家對于LCR數(shù)字電橋有了一定的了解。</p><div

style="text-indent:25px">測試電容器漏電流時,測試時間如何設定?生產(chǎn)線上幾乎不可能按標準的1分鐘來設定測試時間,一般是用抬高漏電流的設定值來相應縮短測試時間,具體的比例關系由各企業(yè)根據(jù)自己的經(jīng)驗公式來確定,一般設定的充電時間都在10秒以內(nèi)(大容值電容和多個電容同時充電的情況除外).LCR數(shù)字電橋在被測元件接入時,接入軸向引線元件時,為避免扭折引線,可采用軸向轉(zhuǎn)接頭,先把這兩個配件分別插入測試夾的兩端,再將其間距調(diào)正到適合元件測量的位置,然后便將軸向引線元件插入兩端的配件夾內(nèi).有了LCR數(shù)字電橋，還需要選擇一款合適的測試夾具才能滿足您的測試需求。山東電橋lcr系統(tǒng)</p><p style="text-indent:25px">LCR數(shù)字電橋選配GPIB接口和電腦相連，編寫相應的軟件，可以實現(xiàn)用電腦控制儀器，進行自動測量。山東電橋lcr系統(tǒng)</p><p style="text-indent:25px">LCR測試儀一般用于測試電感和電容。測量步驟如下：1、設置測試頻率，2、測試電壓或者電流水平，3、選擇測試參數(shù)，比如Z、Q、LS（串聯(lián)電感）、LP（并聯(lián)電感）、CS（串聯(lián)電容）、CP（并聯(lián)電容）、D等，4、儀器校準，校準主要進行開路、短路校準，**的儀器要進行負載校準，5、選擇測試夾具，6、夾具補償，7、將DUT放在夾具上開始測試。以上就是一個完整的步驟了，如果想對測試儀有更多了解可以關注深圳市展榮新精密電子有限公司，專業(yè)從事電子變壓器、電感線圈、電容電阻等各類元器件測試儀之自主研發(fā)、制造和銷售?，F(xiàn)有的主要產(chǎn)品—電子變壓器綜合測試系統(tǒng)、精密LCR數(shù)字電橋和直流微電阻表等，并代理國內(nèi)外**品牌的測量儀表。山東電橋lcr系統(tǒng)</p><p
