style="text-indent:25px">為了減少測量誤差，LCR測試儀具有若干校正功能。校正值根據(jù)頻率和阻抗的量程不同會有所不同，所以進行全范圍的校正要花費很多時間。這里對零點校正和負荷校正進行解說。零點校正:當LCR測試儀的零點漂移對于測量值不能忽略時，就需要進行零點校正。因為零點漂移會隨著電纜和電極的物理配置不同而變化，所以進行開路和閉路的零點校正時，必須與連接零部件時的電纜布線、電極間隔等相同。負荷校正:除了測量夾具等不同所引起的零點漂移以外，如果還有不能夠忽略的測量誤差，那么可以進行負荷校正，以提高測量精確度。即使對于沒有負荷校正功能的LCR測試儀，也能夠對各個阻抗量程和頻率求取校正系數(shù)，自己進行校正。貴州lcr電橋儀選擇傳統(tǒng)LCR電橋的信號源阻抗隨著量程的變化而變化的。</p><div

* Ux/Ur。這個公式是相位量關系公式。從這個結構來看，數(shù)字橋只是繼承了橋的傳統(tǒng)稱呼。LCR數(shù)字電橋在不斷的發(fā)展過程中提高了性能,具有了更強大的數(shù)據(jù)處理能力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">隨著現(xiàn)代模擬和數(shù)字技術的發(fā)展，特別是高速運放，微處理器技術的發(fā)展，現(xiàn)代阻抗測量大都使用自動平衡電橋法。首先由信號源發(fā)生一個一定頻率和幅度的正弦交流信號，這個信號加到被測件DUT上產生電流流到虛地“0V”，由于運放輸入電流為零，所以流過DUT的電流完全流過Rr，根據(jù)歐姆定律DUT的阻抗：Z = V1*Rr/V2。因為運算放大器虛地功能的引入，使這種測量方法的精度和抗干擾能力產生了質的飛躍。當然，以上只是一個比較抽象化的原理模型，真正的產品要復雜的多。深圳市展榮新精密電子有限公司代理國內外**品牌的測量儀表。貴州lcr數(shù)字電橋哪個比較好</p><p
