Yuav ua li cas ntsuas cov xaim xaim nrog lub multimeter
1, nrog multimeter RX10K iav.
2, ib tug cwj mem txais kev ntsuas ntawm firewire, lwm tus cwj mem av.
3, yuav tsum muaj kev tiv thaiv infinity, txwv tsis pub to.
Multimeter tseem hu ua multipurpose meter, multi-purpose meter, peb meters, ib txwm ntsuas, thiab lwm yam, yog ib qho tseem ceeb ntsuas ntsuas rau lub hwj chim electronics thiab lwm yam departments, feem ntau yog ntsuas voltage, tam sim no thiab kuj raws li lub ntsiab lub hom phiaj. Multimeter muab faib ua pointer multimeter thiab digital multimeter raws li hom zaub. Nws yog ib tug multifunctional, ntau yam kev ntsuas ntsuas, dav multimeter tuaj yeem ntsuas DC tam sim no, DC voltage, AC tam sim no, AC voltage, tsis kam thiab suab qib, thiab lwm yam. Qee qhov tseem tuaj yeem ntsuas AC tam sim no, capacitance, inductance thiab qee qhov tsis sib xws ntawm semiconductors ( eg,) thiab lwm yam.
Basic Functions
Multimeter tsis tsuas yog siv los ntsuas qhov tsis kam ntawm cov khoom ntsuas, AC thiab DC voltage kuj tuaj yeem ntsuas DC voltage. Qee qhov multimeters tuaj yeem ntsuas qhov tseem ceeb ntawm cov transistors thiab lub peev xwm ntawm capacitors. Ua tiav kev siv cov multimeter yog ib qho ntawm cov kev txawj ntse tshaj plaws ntawm kev siv tshuab hluav taws xob.
Multimeters feem ntau yog pointer multimeters thiab digital multimeters. Pointer multimeter yog ib qho cuab yeej siv ntau yam ntsuas nrog lub taub hau ua cov ntsiab lus tseem ceeb, thiab ntsuas tus nqi yog nyeem los ntawm tus taw tes ntawm lub taub hau. Digital multimeter ntsuas tus nqi los ntawm cov kua siv lead ua kua tso ncaj qha rau hauv daim ntawv ntawm cov duab digital, nyeem tau yooj yim, qee qhov kuj muaj suab nrov. Multimeter yog ib lub taub hau, teeb ntawm voltmeter, ammeter thiab ohmmeter hauv ib qho cuab yeej.
Multimeter DC tam sim no iav yog ntau hom DC voltmeter. Nws qhov hluav taws xob ntau tuaj yeem txuas ntxiv los ntawm kev txuas lub kaw lus kaw hluav taws xob hluav taws xob faib hluav taws xob sib txuas nrog lub ntsuas lub taub hau. DC voltage ntau ntawm multimeter yog ib tug ntau yam DC voltmeter. Qhov voltage ntau ntawm lub multimeter tuaj yeem nthuav dav los ntawm kev sib txuas ntawm qhov hluav taws xob faib hluav taws xob nyob rau hauv series nrog lub taub hau ntawm lub 'meter'. Txawv voltage divider resistors muaj ntau yam sib txawv. Lub multimeter lub taub hau yog qhov ntsuas magneto-hluav taws xob *, uas tuaj yeem dhau DC, thiab siv lub diode hloov AC rau DC, yog li paub txog qhov ntsuas ntawm AC lub zog.
