Thaum siv mulul ancimeter rau thawj zaug, zam kev ua haujlwm no
1. Nws raug txwv kom siv hom kev tawm tsam, hom tam sim no, thiab capactrance hom ntawm ib tug loj rau kev ntsuas voltage.
2. Tsis txhob siv cov kev tiv thaiv ntau ntau ntawm cov ntau ntawm cov ntau yam ua ke los sim ua neej nyob.
3. Nws raug txwv kom siv tshuaj multimeter kom sim siv hluav taws xob lim hluav taws xob lossis hluav taws xob rov qab muaj peev xwm siv tau thiab muaj theem tso tawm. Tsis txhob txuas ncaj qha txuas rau "+" thiab "-" cov lus ntawm electrolytic capacitors rau luv luv-tso tawm. Yog tias kev tawm mus yog qhov tsim nyog, kev tawm mus ntxiv tawm yuav tsum tau ntxiv los tiv thaiv kev puas tsuaj rau tus capacitor. Thaum rho tawm lub capacitor, rwb thaiv tsev cov hnab looj tes thiab cov kev ntsuas cov kev ntsuas ntau dua li cov tshuaj ntsuam uas tsis muaj kev tiv thaiv thiab ntiv tes hluav taws xob thaum tso tawm.
4. Qhov hloov tau zoo heev thiab cov khoom hloov nrog lub ntsiab lus hloov multimeter ib ce.
5. Nws tsis raug tso cai siv ntau ntau rau high-voltage kuaj hauv cov qus thaum tseem ceeb, txhawm rau tiv thaiv cov neeg ua haujlwm sim los ntawm xob laim.
6. Kuaj cov xov hlau nrog cov rwb thaiv tsev tsis tau thiab cov kab nrib pleb ntawm cov madion maladusatus tsis siv. Yog tias muaj ntau lub vias muaj rau kev sim rau ntawm txoj haujlwm sib txawv, tsis yog txoj haujlwm tsis ncaj ncees rau kev sim, qee qhov yuav tshwm sim.
7. Txij ntawm no, koj tuaj yeem siv cov ntaub ntawv los ua kom lub ntsis ntawm tus cwj mem. Yog hais tias qhov ntxeev ntawm tus cwj mem ntev heev, nws tuaj yeem qhwv nrog cov kab xev rwb thaiv tsev (lossis npog nrog lub raj yas yas) kom pom cov taub hau xwb.
8. Thaum cov teeb liab clip tau tiv tauj tsis zoo, nws kuj tseem tuaj yeem ua rau R * 1 iav kom tsis xoom. Yog tias koj pom tias cov roj teeb elasticity muaj paug, koj tuaj yeem khoov lub caij nplooj ntoo hlav ntse kom ua rau kev sib chwv. Lub cheeb tsam corroded ntawm lub roj teeb clip yuav tsum tau ntxuav kom sai nrog cov hniav lossis cov ntaub qhwv.
