或“1KHz”指示LED來建議更改測量頻率。選擇LCR數(shù)字電橋關心的主要方面：測量準確度，測試信號頻率與電平，儀器價位。數(shù)字lcr電橋評測</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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。深圳lcr數(shù)字電橋哪個比較好LCR數(shù)字電橋的測量速度比較的快,測量出來的精確度比較的高。</p><div

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，早已經淘汰了這種測量方法，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、LCR表、數(shù)字電橋、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?，F(xiàn)有的主要產品—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，并代理國內外**品牌的測量儀表。</p><p style="text-indent:25px">對于LCR數(shù)字電橋的使用來說，正確的選擇所需要的電阻頻率很重要。我們需要知道幾個選擇的規(guī)則。電容小于2nF，選擇，選擇串聯(lián)1KHz，選用高的測試信號可提高測試精度，同樣能量測大于1000μF以上電容。電感小于2mH，用串聯(lián)1KHz，選擇高測試頻率可提高測試精度。電感大于200H，并聯(lián)，120Hz，選擇低測試頻率可提高測試精度。電阻大于等于 1K Ω，選擇并聯(lián)120Hz(100Hz)，選擇低頻減少交流影響，選擇“并聯(lián)”，是因為量測過程中出現(xiàn)電抗部份，等效為被測件并聯(lián)一個電容呈現(xiàn)的高電抗，用并聯(lián)模式減小這種影響，如果Q＜0.1，已存在小電容影響。目前大多的工廠、各種實驗室都會大量的使用到電橋，電橋的品種、型號繁多。</p><div

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。成都臺式lcr電橋</p><p style="text-indent:25px">根據(jù)LCR數(shù)字電橋測量流過被測器件的電流(I)、電壓(v )、電壓與電流的相位角測量結果，可以計算阻抗參數(shù)。數(shù)字lcr電橋評測</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，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。數(shù)字lcr電橋評測</p><p
