Tau hais tias, ntawm no yog cov ntaub ntawv xav tau los ua kom tiav cov txheej txheem no.
Nco ntsoov: Rau qhov demo no, koj tuaj yeem siv lub qhov hluav taws xob hauv tsev tsis tu ncua. Peb yuav piav qhia txhua yam los ntawm qhov hluav taws xob. Txawm li cas los xij, nco ntsoov tias tib txoj kev tuaj yeem siv rau lwm lub voj voog.
Cov Khoom Siv Yuav Tsum: Multimeter, ntswj ntsia hlau, qhov (socket), insulated hnab looj tes, sojntsuam
Kauj Ruam 1: Kev Nyab Xeeb Ua Ntej
Txij li thaum peb tab tom cuam tshuam nrog hluav taws xob, nws yog qhov zoo tshaj plaws los hnav cov hnab looj tes insulated. Tsis tas li ntawd, siv cov tshuaj ntsuam xyuas thaum twg koj xav tau. Yog li nco ntsoov ua raws li cov kev ceev faj no.
Kauj Ruam 2 - Plug thiab Multimeter
Tshem tag nrho peb cov xov hlau los ntawm lub qhov hluav taws xob. Qee zaum koj yuav tsum tau tshem lub hau yas pem hauv ntej kom tau cov xov hlau tawm. Hauv qhov no, siv lub hau ntswj kom tshem tawm cov ntsia hlau thiab lub hau yas. Qee lub sij hawm koj tuaj yeem tau txais cov xov hlau tawm yam tsis tau tshem lub hau yas.
Tam sim no teeb koj lub multimeter mus rau qhov chaw siab tshaj plaws. Tsis tas li ntawd, txij li thaum peb tab tom cuam tshuam nrog AC tam sim no, qhov ntau ntawm multimeter yuav tsum sib txawv. Yog li, ua qhov tsim nyog hloov ua ntej siv lub multimeter.
Kauj Ruam 3 - Siv cov tshuaj ntsuam xyuas dub
Koj lub multimeter yuav tsum muaj ob qhov kev sojntsuam; dub dipstick thiab liab dipstick. Lawv kuj raug hu ua leads. Txuas lub multimeter dub lead rau hauv av xaim lossis lwm yam khoom siv hauv av xws li cov kav dej, tub yees, lossis faucet. Lub multimeter yuav tsum tsis txhob muaj kev nyeem ntawv. Tam sim no peb tuaj yeem pib sim cov kab nruab nrab.
Kauj Ruam 4 - Siv Red Probe
Txhawm rau txheeb xyuas cov xaim nruab nrab, kov cov xov hlau liab qab nrog lub xov tooj liab multimeter. Tej zaum koj yuav tau ua qhov no rau ob lub xov hlau ntxiv (tshwj tsis yog cov xaim hauv av). Yog tias koj tsis tau txais kev nyeem ntawv multimeter, qhov ntawd txhais tau hais tias cov xov hluav taws xob tshwj xeeb yog nruab nrab. Yog tias koj tau txais kev nyeem ntawv, qhov ntawd txhais tau hais tias cov hlau yog kub.
Kev ceev faj koj yuav tsum ua raws
Peb cia siab tias tam sim no koj muaj lub tswv yim zoo ntawm yuav ua li cas ntsuas cov hlau nruab nrab nrog lub multimeter. Txawm li cas los xij, txawm tias koj yog ib tus kws paub txog hluav taws xob, muaj qee qhov kev ceev faj koj yuav tsum ua. Rau koj txoj kev nyab xeeb, ua raws li cov lus ceeb toom no kom raug. (1)
