當(dāng)前國(guó)際上LCR測(cè)量主要以符合通行測(cè)試標(biāo)準(zhǔn)的IEC/MIL標(biāo)準(zhǔn)（國(guó)際電工會(huì)或美國(guó)標(biāo)準(zhǔn)）的美國(guó)Agilent公司的4284A精密LCR測(cè)試儀為標(biāo)準(zhǔn)。而我們?cè)谠O(shè)計(jì)TH2818時(shí)就消化和綜合了4284A的諸多優(yōu)點(diǎn)。主要表現(xiàn)如下：操作界面：TH2819XB采用中、英文雙語(yǔ)選擇和樹狀菜單式操作界面，邏輯性強(qiáng)，容易操作。3250不支持中文，操作界面邏輯性不強(qiáng)，新手不易上手。ADC：TH2819XB采用與4284A類似的當(dāng)前國(guó)際先進(jìn)的多斜積分式AD轉(zhuǎn)換器，分辨率高、速度快、精度高，貴州高頻變壓器測(cè)試儀器購(gòu)買，貴州高頻變壓器測(cè)試儀器購(gòu)買、穩(wěn)定性好。3250采用的是普通的雙斜積分式AD轉(zhuǎn)換器。加直流偏置電流功能，TH2819XB采用與4284A類似的加偏置電流原理，一方面保證了測(cè)量讀數(shù)與4284A的一致性，另一方面這種加電流原理的測(cè)量與穩(wěn)定速度遠(yuǎn)遠(yuǎn)快于傳統(tǒng)的加電流方式。TH2819XB加電流的測(cè)試速度比3250更快，貴州高頻變壓器測(cè)試儀器購(gòu)買。TH2819XB直流偏置測(cè)試結(jié)果與Agilent4284A直流偏置的測(cè)量結(jié)果是基本相同的，3250直流偏置測(cè)試加了諸多人為修正因素以期與4284A相符，但結(jié)果不盡理想。掃描治具盒內(nèi)用繼電器：變壓器掃描測(cè)試主要依靠掃描治具內(nèi)繼電器的切換，繼電器的好壞及壽命長(zhǎng)短直接影響儀器的正?？煽渴褂?。3250采用OMRON的機(jī)械式繼電器，它的電氣壽命為幾十萬(wàn)次數(shù)量級(jí)，動(dòng)作時(shí)間為4ms。嚴(yán)禁超額定電壓使用。貴州高頻變壓器測(cè)試儀器購(gòu)買</p><div

4、校準(zhǔn)儀器，用700K歐姆陶瓷電阻跨接于底線夾同高壓測(cè)試棒之間至儀器報(bào)警為準(zhǔn)。 </p> <p> 5、設(shè)定測(cè)試條件：電壓3500伏，漏電流5毫安，測(cè)試時(shí)間為4秒鐘。 </p> <p>
