Yuav ua li cas siv ib tug multimeter los ntsuas qhov 'on' thiab 'off' xeev ntawm ib kab nyob
Yuav ua li cas siv multimeter los ntsuas qhov zoo thiab qhov tsis zoo ntawm lub cev muaj zog, yuav ua li cas siv multimeter, yuav ua li cas siv multimeter los ntsuas qhov zoo thiab qhov tsis zoo ntawm lub capacitor ntsig txog cov lus qhia yuav ua li cas siv multimeter los ntsuas lub zog ntawm cov nqi kab
Hauv hluav taws xob engineering, lub zog rub sab hauv, hluav taws xob muab faib ua hluav taws xob tsis muaj zog, hluav taws xob muaj zog, thiab muab faib ua hluav taws xob tsawg, hluav taws xob siab, ultra-high voltage. Tab sis sab hauv cov hluav taws xob tsis muaj zog, muaj hluav taws xob muaj zog thiab txawm tias muaj hluav taws xob siab, xws li TV, hloov hluav taws xob, LED teeb lub zog, tsis muaj zog rau ob peb volts ntawm hluav taws xob, siab tshaj 10, 000 volts. High voltage nyob rau hauv lub hwj chim uas tsis muaj hluav taws xob thiab tsis muaj zog, vim hais tias cov kev tswj qhov system tswj yog tsis tshua muaj voltage tswj kev kub siab, tsis muaj zog tswj tsis muaj zog voltage, yog ua hauj lwm yam xyuam xim.
Yog hais tias koj tsuas siv ib tug multimeter los ntsuas cov energized kab nyob rau hauv thiab tawm, kuv tsis nyob rau hauv favour! Koj tuaj yeem siv tus cwj mem hluav taws xob los ntsuas qhov muaj lossis tsis muaj hluav taws xob, lossis, tom qab lub hwj chim txiav tawm, siv lub ohm nres los ntsuas kab zoo lossis qhov phem.
Hluav taws xob yog ib qho kev lag luam uas muaj kev pheej hmoo siab, yuav muaj sij hawm thaum koj yuav tsum ntsuas cov ntaub ntawv, thiab tsis muaj hluav taws xob tsis muaj txoj hauv kev los ntsuas qhov tseeb cov ntaub ntawv voltage, tam sim no. Thiab waveforms. Kev ntsuas kev ntsuas thiab yog nyob rau hauv kev ua haujlwm raug them, txawm hais tias muaj cov khoom pov hwm kev ua haujlwm, cov hnab looj tes insulated, cov khau insulated, tus txiv neej nrog kev ua haujlwm yog qhov tsis yooj yim, cov phooj ywg hais tias txoj haujlwm nyuaj ua nws!
Raws li yuav ua li cas siv lub multimeter, koj tuaj yeem nyeem phau ntawv qhia, ntawm Baidu, cov txiv neej tau teb zoo heev Kuv yuav tsis rov hais dua, Kuv xav qhia cov ntawv ntawm kev ntsuas bandwidth yuav ua li cas ua haujlwm zoo dua thiab siv ntau yam kev nyab xeeb. .
Kev ntsuas hluav taws xob ntsuas hluav taws xob tsis muaj zog
Kev ntsuas yuav tsum tsis txhob ua ntej qhov muag tsis pom kev ntsuas, tshuaj xyuas lub voj voog ntawm lub zog tsis muaj zog thiab muaj zog, xaiv lub iav zoo, ntsuas DC, AC24V voltage hauv qab qhov yooj yim tsis muaj kev phom sij, tab sis tsis txhob kov cov khoom siv hluav taws xob, thiab cov khoom siv hauv qhov hluav taws xob siab, xws li zoo li loj capacitors.
Kev ntsuas cov khoom siv hluav taws xob tsawg hauv high-voltage, txoj hauv kev zoo tshaj plaws yog thawj lub hwj chim tawm, tso tawm (suav nrog cov capacitors) thiab tom qab ntawd tus cwj mem 'meter' xaiv lub iav zoo, muab tso rau hauv qhov ntsuas qhov ntsuas zoo, thiab tom qab ntawd xa lub zog mus rau nyeem cov ntaub ntawv ntsuas, digital multimeter nrog lub cim xeeb khawm, koj tuaj yeem nias lub cim xeeb khawm, yog li nws yuav muaj kev nyab xeeb dua.
Thaum ntsuas qhov voltage nrog multimeter nyob rau hauv lub Hoobkas, qhov voltage tsis tas kab yog los ntawm, tsis muaj voltage kab yog twv yuav raug hu tsis.
Raws li kev ntsuas ntsuas, muaj cov transformers thiab motors nyob rau hauv kab, muaj hwj chim nyob rau hauv lub breakpoint, thiab muaj hwj chim nyob rau hauv lub breakpoint, lub hwj chim ntawm lub breakpoint yog lub hwj chim mov, thiab lub hwj chim nyob rau hauv lub breakpoint yog lub hwj chim. ntawm lwm theem los ntawm winding lossis coil hlua hla lub zog, yog li peb yuav tsum tau them sai sai rau qhov tshwm sim no. Yog li nrog ib tug multimeter nrog lub hwj chim los ntsuas txoj kab ntawm thiab tawm yog tsis ntsuas! Rau kev siv hluav taws xob hluav taws xob, yuav tsum yog lub zog ib zaug, cov kab hluav taws xob tawg, tsis muaj lub zog, tab sis xoom kab tawg, yuav ntsuas qhov tshwm sim ntawm lub zog tsis muaj hluav taws xob.
Piv txwv li, nrog ib tug multimeter nrog lub hwj chim los ntsuas txoj kab los ntawm tsis yog, tau nws tsis ncaj ncees lawm, tsis yog lawv tus kheej winding rau nws, txoj kev zoo tshaj plaws yog siv lub ohm thaiv tom qab lub hwj chim tsis ua hauj lwm, los yog siv lub pob zeb ntsuas ntsuas. txoj kab dhau los yog qhov tseeb dua.
