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(zhǔn)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(shù)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(biāo)準(zhǔn)測試中等電容的測試頻率標(biāo)準(zhǔn)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(yīng)仔細選擇電平。</p><p style="text-indent:25px">LCR數(shù)字電橋其多種輸出阻抗模式可以適應(yīng)各個電感變壓器廠家的不同標(biāo)準(zhǔn)需求.LCR數(shù)字電橋量程自動功能就是儀器每次測量都會根據(jù)測試端被測件的阻抗大小去尋找對應(yīng)的量程.這主要應(yīng)用于被測件阻抗未知的情形.LCR數(shù)字電橋在使用時所有元件測試儀器設(shè)計的時候雖然都做了抗沖擊保護設(shè)計,但是測試電容前還是要保證電容不帶電,這樣可以保證儀器穩(wěn)定的準(zhǔn)確測試和較長的使用壽命.要保持被測試產(chǎn)品引腳表面導(dǎo)電性能良好好,才能保證測試結(jié)果準(zhǔn)確一致性好.測量元件、傳感器或其他設(shè)備的電感、電容、電阻的LCR數(shù)字電橋，可根據(jù)電容、電感或電阻進行工作。</p><div

src="https://tyunfile.71360.com/UploadFile/ZRX888/637284365269062500/8221799.png"></div><p style="text-indent:25px">LCR測試儀測試原理：Vx與Vr均是矢量電壓表，Rr是理想電阻。LCR測試儀自平衡電橋的意思是：當(dāng)DUT(Device Under Test)接入電路時，放大器的負反饋配置自動使得OP輸入端虛地。Vx準(zhǔn)確測定DUT兩端電壓（DUT的Low電位是0），Vr與Rr測得DUT電流Ix，由此可計算Zx。LCR測試儀提高精度的方法是: 1,Hp,Lp,Hc,Lc盡量接近DUT; 2,減小測試電流Ix的回路面積&磁通量（關(guān)鍵是分析Ix，要配合使用Guard與Cable*小化回路面積);3,使用Gurard與Cable構(gòu)建地平面中斷信號線間的電場連接，雖然會增加信號線的對地電容（對地電容不影響測試結(jié)果），但是會減少信號線的互容。Guard與Cable的對地寄生阻抗（Zhg,Zlg) 不影響測試結(jié)果，電橋平衡時Zlg的兩端電壓是0，流向Rr的電流不會被Zlg分流，Zhg的分流作用不影響Hp的電壓測量。正確合理的使用LCR數(shù)字電橋，會極大的提高LCR數(shù)字電橋的使用壽命。浙江lcr電橋表系統(tǒng)選擇</p><p style="text-indent:25px">LCR數(shù)字電橋主要由正弦信號發(fā)生器、精密量程電阻、鑒相器和高精度A/D轉(zhuǎn)換器組成。湖南數(shù)字電橋lcr系統(tǒng)</p><p style="text-indent:25px">LCR電橋測試信號檢測：施加于被測件的電平是十分重要的。實際施加于被測件上的電平（電壓或電流）與儀器信號源阻抗有關(guān)，雖然儀器電平相同，若信號源阻抗不同，實際施加于被測件上的電平就不同。自動電平控制對某些與信號電平相關(guān)性強的器件，保持施加恒定的測試信號電平（電壓或電流）是非常重要的。TH2818、TH2819、TH2828/A/S 具備了電平的自動控制功能，這對相關(guān)性強的元件的測量是極為有用的。信號源輸出阻抗：傳統(tǒng)LCR電橋的信號源阻抗隨著量程的變化而變化的，這樣，不同的元件測量時的實際電平變化極大，這對某些器件的測量是不合理的。湖南數(shù)字電橋lcr系統(tǒng)</p><p
