Nkag siab voltage ntsuas nrog tus multimeter
Kev ntsuas ntsuas hluav taws xob feem ntau yuav muab faib ua kev ntsuas DC voltage thiab kuaj AC Voltage, thaum ntsuas qhov tam sim no tuaj yeem faib ua kev sim DC tam sim no thiab kuaj AC tam sim no. Ua ntej tshaj plaws, thaum kuaj lub hwj chim muab voltage, koj yuav tsum ceev faj. Thaum ntsuas qhov ntsuas hluav taws xob, thawj qhov koj yuav tsum tau ua yog los txiav txim siab seb koj puas tau kuaj AC Voltage lossis DC voltage. Ntawm no, Kuv xav qhia txhua tus neeg paub tias cov khoom lag luam pej xeem yog txhua voltage, tab sis lwm cov ntaub ntawv siv hluav taws xob thiab lwm cov ntaub ntawv siv hluav taws xob dc voltage. Qhov no tuaj yeem yog ib qho teeb meem me ntsis thaum kuaj, yog li nws yog qhov tsim nyog kom paub qhov txawv ntawm AC thiab DC ua ntej ntsuas. Yog tias koj tsis paub tias qhov voltage yog qhov tseeb tiag tiag los yog tam sim no thaum ntsuas, koj yuav tsum muab tso rau hauv AC hom los npaj rau ntau yam teeb meem thaum sim. Txij ntawm no, koj yuav tsum tau maj mam kho thiab hloov los ntawm lub siab rau lub siab * lub iav qis kom txog thaum koj ncav cuag tus nqi xav tau. Thaum siv cov twj paj nruag no thaum pib, qib ntsuas yog qhov tseem ceeb heev. Qhov xwm txheej tseem ceeb koj yuav tsum nco ntsoov yog qhov kev xaiv iav kuaj yog qhov tseeb thiab seb cov tshuaj tua hluav taws xob sib sau ua ke. Yog tias koj raug mob rau kev sojntsuam rau hauv lub qhov (socket) tam sim no thaum ntsuas hluav taws xob, tom qab ntawd koj ua tiav, vim tias kev sim tsis raug rau cov iav tam sim no kom hlawv. Thaum kuaj cov multimeter, nws yog ib qho tseem ceeb kom tsim kho tus cwjpwm zoo ntawm kev hloov pauv hom rau AC Voltage hom kev siv, thiab ntxig qhov kev sojntsuam rau hauv lub tshuab hluav taws xob. Tus cwj pwm zoo no tseem muaj txiaj ntsig zoo rau kev ua haujlwm ua haujlwm yav tom ntej, txwv tsis pub koj yuav tau them tus nqi kawm ntawv qib.
