Cov lus qhia rau kev ntsuas DC nrog tus multimeter
1, ua kev xoom txhua xo.
2, Xaiv cov iav uas tsim nyog.
3, thaum ntsuas ntsuas tam sim no nrog hom kev sib ntxiv tam sim no, kev sib txuas nrog cov kev sib txuas ntawm kev sib txuas tam sim no tuaj yeem ua rau qhov tam sim no los ntawm kev ntsuas tib yam li kev ntsuas. Thaum ntsuas cov ceg yuav tsum tau txiav tawm thiab cov kev sim liab thiab xim liab thiab xim dub ntawm kev sib xyaw ua ke yuav tsum txuas nrog hauv cov ntsiab lus ntawm ob ntawm ob qho ntsiab lus. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov ammeter rau kev sib txuas nrog kev sib tw ntawm kev sib tw ntawm kev sib tw ntawm cov kev phom sij
4, them nyiaj rau cov polarity ntawm cov hluav taws xob ntsuas.
5, Siv tau raws nplai thiab nyeem.
6, Thaum xaiv cov 2.5A hom nrog DC tam sim no, kev sojntsuam liab ntawm kev sib tw yuav tsum tso rau hauv ib qho ntawm DC tam sim no hom.
7, Yog tias DC tam sim no yog ntau dua 2.5A, lub 2.5a ntau ntxiv tuaj yeem txuas ntxiv mus rau 5A ntau. Tus txheej txheem yooj yim heev. Tus neeg siv tuaj yeem txuas ib qho 0. 24 Ohm resistor nruab nrab ntawm "2.5A" Kev Soj Ntsuam Dub (kom lub iav Qhov {0. 24A resistor siv rau kev txuas yuav tsum yog ib tus kais dej tiv tsawg kawg yog 2W. Yog tias lub zog qis dhau, nws yuav hlawv.
Yooj yim paub qhov txawv ntawm nruab nrab thiab nyob hauv xov hlau nrog lub multimeter
Koj tuaj yeem yooj yim ntsuas qhov nruab nrab thiab cov xov hlau nyob hauv koj lub tsev nrog ntev tshaj plaws, ntev li koj siv cov qauv siv tshuab ntau heev, lossis cov khoom siv tshuaj ncab motimeter rau ntawm AC Voltage ntau. Tig cov kab hloov ntawm ntau qhov hloov ntawm cov poltimeter ntau (tag nrho cov ntau yam, koj tuaj yeem xaiv ntau dua, koj tuaj yeem xaiv 10V100V). Tom qab ntawd ntxig cov liab thiab dub probes rau hauv v / com (lub qhov (lub qhov (qhwv cov khoom siv dub ntawm cov khoom siv dub {}} Ntawm chav kawm, ntau dua, qhov zoo dua. Nco tseg: Lub sijhawm no, tsis txhob kov cov hlau rab koob ntawm cov kev sojntsuam dub nrog koj txhais tes tiv thaiv kom tiv thaiv hluav taws xob. Tom qab ntawd koj tuaj yeem sim nws. Nqa cov kev sojntsuam liab thiab ntsuas lub qhov (socket) lossis nruab nrab ntawm cov hlau cais. Sau cov txiaj ntsig ntawm ob ntsuas, thiab yuav tsum muaj qhov loj thiab qhov dav dav ntawm lawv. Qhov loj dua voltage ntsuas yog cov hlau nyob, thiab cov voltage me me yog ntawm chav kawm nruab nrab ntawm cov hlau nruab nrab. Yog tias cov av xaim ntsuas yog ntsuas, yuav tsum tsis muaj qhov ntau dua lossis tsis muaj voltage (nyob ntawm seb koj lub tsev cov xaim txuas nrog). Qhov sib txawv ntawm cov ntsuas hluav taws xob ntawm cov xaim nruab nrab thiab cov xaim hluav taws xob yog ntshiab ntawm ib nrais muag.
