Taw qhia rau dab tsi lub multimeter yog siv los ntsuas
Ib tug multimeter, tseem hu ua compultimeter lossis reusable meterable, yog qhov yooj yim thiab qhov tseem ceeb ntsuas cov cuab yeej siv hluav taws xob. Nws cov haujlwm yooj yim suav nrog ntsuas ntsuas ntsuas AC / DC tam sim no, kev ntsuas cov neeg muaj zog, thiab cov neeg siv hluav taws xob tau sib npaug
Ib tug multimeter muaj qhov zoo ntawm versatural versatility, ntau yam, thiab siv yooj yim, ua rau nws cov cuab yeej siv feem ntau hauv kev ntsuas hluav taws xob. Nws tuaj yeem siv los ntsuas tiv thaiv, AC / DC voltage, thiab dc voltage. Qee tus neeg muaj peev xwm kuj tseem tuaj yeem ntsuas qhov tseem ceeb ntawm cov transistors thiab lub capacitance ntawm capacitors. Mastering cov kev siv ntawm ib tug multimeter yog qhov kev txawj ntse hauv cov tshuab hluav taws xob.
Cov multimeters suav nrog cov multipeters multimeters thiab digital multivers. Tus pointer hom mulceteral ntsuas ntsuas nrog lub taub hau ntsuas nrog cov tseem ceeb yog nyeem los ntawm tus poter ntawm lub taub hau ntsuas. Qhov ntsuas ntsuas qhov tseem ceeb ntawm cov digital pululimeter yog ncaj qha rau hauv daim foos digital ntawm LCD npo, ua rau nws yooj yim nyeem. Ib txhia txawm muaj suab hais kom sai. Lub taub hau sib xyaw muaj cov khoom siv hluav taws xob rau kev khaws hluav taws xob
Qhov ntsuas uas sib xyaw ua ke ntawm lub siab, ib qho kev ammeter, thiab ib tug ohmampeter. DC tam sim no ntau ntawm cov multimeter yog ntau ntau ntau dc voltmeter. Parallel kev sib txuas ntawm lub circuital Circuital voltage divider resistor nyob rau hauv lub taub hau ntsuas tuaj yeem nthuav nws cov hluav taws xob.
Lub DC voltage ntau ntawm cov multimeter yog ntau ntau ntau dc voltmeter. Txuas cov hluav taws xob tiv thaiv nyob rau hauv series nrog lub taub hau ntsuas tuaj yeem nthuav nws cov hluav taws xob ntau. Cov kev sib txawv ntau txawv nyob ntawm cov voltage divider resistor.
Lub taub hau ntawm pultimimeter yog lub magneto hluav taws xob ntsuas hluav taws xob ntsuas, uas tsuas yog ntsuas AC lub zog los ntawm kev hloov ACT DC siv dodes.
Ntawm lub hauv paus ntawm txoj kev sib txuas tam sim no, ntxiv roj teeb, faib cov resistor, thiab band hloov ua ib ohmarketer.
