style="text-indent:25px">數(shù)字電橋產(chǎn)品磨損老化之后會造成什么樣的問題的呢?很常見的恐怕就是檢測數(shù)據(jù)不準(zhǔn)確了,對大多數(shù)的檢測而言,數(shù)據(jù)不準(zhǔn)確不**是誤差的問題,會讓檢測和實(shí)驗(yàn)喪失意義.也就是說如果一個數(shù)字電橋的檢測數(shù)據(jù)不準(zhǔn)確,重復(fù)性不強(qiáng)就意味這臺數(shù)字電橋已經(jīng)喪失了它存在的意義.因此,我們在選購數(shù)字電橋時心中的性價比不**是產(chǎn)品功能和價格之比,要充分考慮到產(chǎn)品的有效使用壽命.而不是**看到眼前的產(chǎn)品和價格,要更多的去考慮產(chǎn)品使用一定期限之后檢測結(jié)果的穩(wěn)定性和精確性.這才是數(shù)字電橋產(chǎn)品性價比的真正體現(xiàn).lcr自動測量儀評測通過本文的介紹，相信大家對于LCR數(shù)字電橋有了一定的了解。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="成都lcr 測量儀,lcr" src="https://tyunfile.71360.com/UploadFile/ZRX888/637284365556523438/6064664.png"></div><p style="text-indent:25px">LCR電橋的使用方法主要是先將電源線帶IEC一端接到電橋左后方的IEC 插座上，另一端插入合適的電源插座上，搬動電橋左后方的船形開關(guān)，即使電橋通電。通電后，顯示器、量程及功能指示器隨之變亮。電橋可自動置于電感、電容測量檔，并聯(lián)等效及1KHz頻率狀態(tài)。正常情況下，內(nèi)部電路加電幾秒鐘后即能穩(wěn)定，便可進(jìn)行測量。被測元件的接入方法：1.通常徑向引線的元件可直接插入組合測試夾夾板內(nèi)，而接入特殊柔性引線的元件時，應(yīng)借助夾板離合器進(jìn)行，該離合裝置位于測試夾的正下方。2.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)。3.在軸向轉(zhuǎn)接頭必需相當(dāng)牢固定的場合，如在測量大量的同類元件時，需采用支撐板。</p><p style="text-indent:25px">在振動式料位開關(guān)研發(fā)中，一般通過LCR數(shù)字電橋來準(zhǔn)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(yīng)設(shè)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(jié)果還與測量環(huán)境密切相關(guān)，特別是環(huán)境濕度和空氣流動，這導(dǎo)致儀表顯示結(jié)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。經(jīng)濟(jì)實(shí)用型LCR數(shù)字電橋，可以滿足一般的測試要求。</p><div

style="text-indent:25px">LCR與試樣的四端子法:設(shè)置**的電壓檢測電纜，以消除由于測試電纜的串聯(lián)阻抗所引起的電壓降和接觸電阻的影響等，是一種減少低阻抗零部件的測量誤差的方法。需要考慮由于電纜之間的互電感（M）所產(chǎn)生的影響。如果使用在一個夾子上有2個相互絕緣的電極的開耳芬夾子，那么用2個夾子可以容易地進(jìn)行4個端子的連接。LCR與試樣的四端子對法:對于交流阻抗的測量，與直流測量不同，其特點(diǎn)是不會受到溫差電動勢的影響。但是，由于電流電纜與電壓電纜之間的電磁感應(yīng)，測量的頻率越高，要想測量低阻抗就越困難。對于這個問題，可以利用電纜的屏蔽層，使電流的去路和歸路相互重疊，以抑制磁通量的產(chǎn)生，由此來減少由于電磁感應(yīng)所引起的殘留阻抗。LCR電橋儀器提供的簡單的分選功能及易于設(shè)置分選極值的方法為大批量的分選器件提供了方便。中山精密lcr數(shù)字電橋系統(tǒng)</p><p style="text-indent:25px">測量LCR數(shù)字電橋準(zhǔn)確度是反映儀器性能的主要指標(biāo)之一。成都lcr 測量儀</p><p style="text-indent:25px">怎樣選擇串聯(lián)和并聯(lián)測試參數(shù)? (1)可以兩個不同的測試頻率下?lián)p耗因子的變化性來決定，若頻率升高而損耗增加，則應(yīng)選用串聯(lián)等效電路若頻率升高而損耗減小，則應(yīng)選用并聯(lián)等效電路。對于電感來說，情況正好與電容相反。實(shí)際中器件的D 不可能與頻率完全成正比關(guān)系，其可能有并聯(lián)成分，也可能有串聯(lián)成分，應(yīng)看何種成分占主導(dǎo)。(2)根據(jù)元件的使用情況來判定。如用于信號耦合電容，則優(yōu)先選擇串聯(lián)方式，旁路或并聯(lián)諧振則使用并聯(lián)等效電路。習(xí)慣上說低阻抗元件用串聯(lián)，從數(shù)值上說阻抗小于100歐姆一定用串聯(lián)，大于10千歐用并聯(lián)，(100歐姆-10千歐)根據(jù)實(shí)際情況選擇。成都lcr
