Uas muaj ntau yam siv rau kev siv rau voltage ntsuas; Yuav ua li cas los ntsuas tam sim no nrog tus multimeter
Tus motiveter yog qhov ntsuas hluav taws xob siv los ntsuas kev ntsuas, tam sim no, thiab kev tawm tsam. Nws yog cov cuab yeej siv uas siv rau cov tshuab hluav taws xob, cov tshuab hluav taws xob, thiab cov uas muaj kev xav tau tam sim no thiab hluav taws xob. Thaum siv ntau qhov kev ntsuas ntsuas ntsuas hluav taws xob, nws yog qhov tsim nyog los xaiv cov iav tsim nyog. Thaum ntsuas ntsuas tam sim no, nws yog qhov yuav tsum tau them sai sai rau kev nyab xeeb ntawm cov twj paj nruag thiab xaiv cov ntsuas ntsuas kom tsim nyog.
Ua ntej siv ntau qhov kev ntsuas ntsuas ntsuas hluav taws xob, nws yog qhov tsim nyog los xaiv thawj zaug cov iav tsim nyog. Feem ntau, peb tuaj yeem xaiv cov iav tsawg kawg nkaus me ntsis dua li ntsuas tus nqi. Qhov tsawg kawg nkaus iav yuav ntsuas voltage qhov tseem ceeb ntau dua, thaum lub iav ntau dua tuaj yeem zam cov ntsuas kev ntsuas kom muaj nuj nqis.
Tom ntej no, txuas ob qhov kev xeem Cill rau ob qhov kawg ntawm cov voltage kom kuaj. Feem ntau, tus cwj mem liab yog siv los txuas tus ncej zoo, thiab cov cwj mem dub muag yog siv los txuas tus ncej tsis zoo. Nyob rau hauv txoj kev no, cov zaub pom ntawm motimeter yuav qhia tus nqi ntawm cov voltage ntsuas kom ntsuas.
Nws yuav tsum raug sau tseg tias qhov ntau ntau muaj ob qho kev ntsuas seb: DC voltage thiab AC voltage. Ua ntej ntsuas hluav taws xob, nws yog qhov tsim nyog los xaiv hom voltage ntsuas tau ntsuas los ntawm kev xaiv lub pob qhov rooj ntawm lub ntsuas. Yog tias tsis yog lwm yam teev tseg, DC voltage ntsuas ntau yam tuaj yeem xaiv los ntawm lub neej ntawd.
Thaum ntsuas ntsuas tam sim no, tej zaum yuav muaj teeb meem ntxiv thiab kev nyab xeeb. Since current measurement is achieved by inserting resistors into the circuit and measuring the voltage across the resistors, it is necessary to ensure that the resistors in the circuit can stably pass current.
Ua ntej ntsuas qhov tam sim no, nws yog ib qho tsim nyog los ua ntej nrog Circuit Court thiab tom qab ntawd xaiv cov iav tsim nyog. Thaum xaiv cov iav tam sim no, nws yog qhov tseem ceeb kom them sai sai rau cov ntsuas tam sim no thiab xaiv cov iav tsawg tshaj plaws uas yog ntsuas me ntsis.
Tom ntej no, ntxig rau tus cwj mem rau ntsuas tam sim no mus rau hauv lub qhov muag uas tsim nyog ntawm qhov ntsuas. Nco ntsoov tias thaum ntsuas qhov tam sim no, tus cwj mem liab yuav tsum tau ntxig rau hauv lub ntsuas phoo ua "lossis" "ntawm qhov ntsuas kev ntsuas dub) Nyob rau hauv txoj kev no, pulcalimeter tuaj yeem pib ntsuas qhov tam sim no.
Thaum ntsuas ntsuas tam sim no, nws yog qhov tsim nyog los txuas ob qhov kev xeem ntawm lub twj paj nruag mus rau ob daim nodes hauv lub voj voog. Feem ntau, tus cwj mem liab tau txuas nrog rau qhov tam sim no inflow, thaum tus cwj mem dub muag tau txuas nrog qhov kev tawm ntawm kev tawm tshiab tam sim no.
Nws yuav tsum tau sau tseg tias thaum ntsuas ntsuas tam sim no, lub load tsis kam nyob rau hauv Circuit Court yuav qhia tsis meej. Yog li ntawd, txhawm rau txo qis kev ntsuas tsis yog, ib qho kev ntsuas me dua tuaj yeem xaiv lossis ntsuas tshwj xeeb tuaj yeem siv tau.
Thaum lub sijhawm ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau them ib zaug rau kev nyab xeeb ntawm cov multimeter. When inserting and removing the test pen for measuring current, it is necessary to ensure that the circuit is in a disconnected state to avoid the risk of electric shock caused by excessive current.
Qhov saum toj no yog cov kauj ruam yooj yim rau kev ntsuas voltage thiab tam sim no siv ntau. Hauv kev ua haujlwm zoo, cov iav tsim nyog yuav tsum tau raug xaiv raws li cov teeb meem tshwj xeeb, thiab cuam tshuam hluav taws xob kev nyab xeeb yuav tsum tau ua raws.
