Tsis txhob ua cov haujlwm no thaum siv Multimeter thawj zaug
1. Nws yog txwv tsis pub siv hom kev tiv thaiv, hom tam sim no, thiab hom capacitance ntawm multimeter los ntsuas qhov voltage.
2. Tsis txhob siv qhov kev tiv thaiv ntau yam ntawm lub tshuab multimeter los kuaj cov kab hluav taws xob nyob.
3. Nws yog txwv tsis pub siv ib lub multimeter los kuaj lub hwj chim lim capacitors los yog lub hwj chim replenishment capacitors uas nyuam qhuav tau powered tawm thiab muaj theem tawm. Tsis txhob txuas ncaj qha rau "+" thiab "-" terminals ntawm electrolytic capacitors rau luv luv-circuit discharge. Yog tias tsim nyog, yuav tsum tau ntxiv cov hluav taws xob txuas ntxiv txhawm rau tiv thaiv kev puas tsuaj rau lub capacitor. Thaum tso tawm lub capacitor, cov ntaub ntawv rwb thaiv tsev thiab cov hnab looj tes tsim nyog uas muaj qhov ntsuas ntau dua li qhov ntsuas capacitor yuav tsum tau hnav kom tiv thaiv arcing thiab ntiv tes kub thaum tawm.
4. Exquisite range switch and item switch with a point switching multimeter thaum lub sij hawm xeem txheej txheem.
5. Nws tsis raug tso cai siv lub tshuab ntsuas hluav taws xob rau siab - qhov ntsuas hluav taws xob hauv cov tsiaj qus thaum muaj cua daj cua dub, txhawm rau tiv thaiv cov neeg ua haujlwm kuaj tsis txhob raug xob laim.
6. Kev ntsuas cov xov hlau tsis zoo nrog cov rwb thaiv tsev tsis zoo thiab cov kab nrib pleb ntawm lub vaj huam sib luag multimeter yuav tsum tsis txhob siv. Yog tias muaj ntau lub qhov (socket) muaj rau kev sim ntawm lub vaj huam sib luag multimeter, tsis txhob ntsaws rau hauv qhov tsis ncaj ncees lawm rau kev sim, txwv tsis pub muaj qhov tshwm sim loj heev.
7. Qee qhov multimeters muaj qhov tuab tuab qhov kawg, uas tuaj yeem ua rau luv luv Circuit Court yooj yim thaum kuaj xyuas hluav taws xob circuits. Hauv qhov no, koj tuaj yeem siv cov ntaub ntawv los ua kom lub ntsej muag ntawm tus cwj mem. Yog hais tias lub hau ntawm tus cwj mem ntev dhau lawm, nws tuaj yeem qhwv nrog rwb thaiv tsev daim kab xev (los yog npog nrog ib lub raj yas) kom nthuav tawm tsuas yog lub taub ntawm tus cwj mem.
8. Thaum lub roj teeb clip muaj kev sib cuag tsis zoo, nws kuj tuaj yeem ua rau lub iav R * 1 tsis ua rau xoom. Yog tias koj pom tias qhov elasticity ntawm lub roj teeb clip tau deteriorated, koj tuaj yeem khoov lub ntsej muag lub ntsej muag kom ua kom elasticity thiab txo qhov kev tiv thaiv. Qhov chaw corroded ntawm lub roj teeb clip yuav tsum tau muab ntxuav tam sim nrog cov hniav los yog cov ntawv xuab zeb.
