Lub zog ntawm qhov hluav taws xob tam sim no (amperage) yog tus nqi hluav taws xob uas ua los ntawm cov khoom siv hluav taws xob, xws li cov xov hlau. Lub zog ntawm qhov hluav taws xob tam sim no ntsuas tus naj npawb ntawm cov hluav taws xob uas dhau los ntawm qee qhov taw tes hauv lub sijhawm muab sijhawm, nrog 1 ampere (lossis "amp") sib npaug rau 1 coulomb ib pliag. Kev ntsuas amperage yog qhov tseem ceeb heev thaum koj cuam tshuam nrog cov hluav taws xob hluav taws xob, tshwj xeeb tshaj yog kom ntseeg tau tias tsis muaj xov hlau hla dhau nrog cov dej ntws. Koj tuaj yeem ntsuas hluav taws xob tam sim no nrog cov cuab yeej tshwj xeeb hu ua multimeter.
Kauj ruam
Kauj Ruam 1. Txheeb xyuas qhov ntsuas qhov ntsuas ntawm lub ntsuas cua
Multimeter yog lub cuab yeej me me uas tuaj yeem siv los ntsuas qhov ntsuas hluav taws xob, kev tiv thaiv, thiab hluav taws xob tam sim no. Txhua tus qauv muaj qhov ntsuas rau kev tuav tus nqi tshwj xeeb ntawm tam sim no, thiab qhov ntsuas no yuav tsum phim cov cuab yeej hluav taws xob uas koj xav ntsuas. Piv txwv li, yog tias koj siv lub ntsuas ntsuas ntsuas ntawm 10 amperes los ntsuas 200 amperes, lub ntsuas qhov ntsuas yuav raug puas ntsoog. Qhov ntsuas qhov amperage no yuav teev rau ntawm chav tsev thiab hauv phau ntawv siv khoom lag luam.
Kauj Ruam 2. Xaiv qhov tsim nyog ua haujlwm multimeter
Feem ntau cov ntsuas ntsuas muaj lub luag haujlwm ntsuas ntau qhov ntau. Txhawm rau ntsuas hluav taws xob tam sim no, koj yuav tsum teeb tsa lub luag haujlwm rau DC lossis AC, raws li cov txheej txheem hluav taws xob hauv kev sim. Lub kaw lus lub zog siv hluav taws xob yuav txiav txim seb hom hluav taws xob zoo li cas. Piv txwv, lub zog hauv tsev yog AC, thaum lub zog los ntawm lub roj teeb yog DC.
Kauj Ruam 3. Teev qhov ntau ntawm koj lub multimeter
Txhawm rau kom ntseeg tau tias lub axis ntawm koj lub multimeter tsis puas, teeb qhov siab tshaj plaws amperage rhiab siab tshaj qhov koj kwv yees. Koj tuaj yeem txo nws yog lub multimeter tsis nyeem dab tsi thaum txuas nrog koj lub kaw lus.
Kauj Ruam 4. Txuas tooj liab kawg rau lub davhlau ya nyob twg
Koj lub multimeter los nrog 2 xaim, ib qho nrog cov hlau taub thiab lwm qhov nrog cov tooj liab. Txuas ob lub xov hlau mus rau qhov chaw tsim nyog los ntsuas qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob. Phau ntawv qhia cov cuab yeej yuav qhia qhov tseeb qhov tseeb, yog tias cov ntawv tsis pom meej.
Kauj Ruam 5. Qhib lub phiaj hluav taws xob nrog lub ntsuas cua los ntsuas qhov tam sim no
Cov kauj ruam no txaus ntshai heev thiab tuaj yeem ua rau hluav taws xob poob qis yog tias koj ntsuas tsev neeg AC tam sim no, lossis lwm qhov hluav taws xob qhov hluav taws xob thiab qhov muaj zog tam sim no, lossis txawm tias lub zog hluav taws xob qis tam sim no. Tua txhua lub tshuab hluav taws xob ua ntej ua haujlwm thiab siv cov hlau kawg ntawm AC ntsuas kom pom tias AC raug tshem tawm tag ua ntej kov cov xov hlau, tshwj xeeb tshaj yog cov ntu uas tsis tau qhwv hauv zaj duab xis tiv thaiv. Tsis txhob ua haujlwm hauv qhov chaw ntub lossis qhov chaw ntub me ntsis vim dej coj hluav taws xob thiab tuaj yeem ua rau koj raug mob. Hnav hnab looj tes roj hmab. Ua lwm yam kev tiv thaiv. Tham nrog tus kws hluav taws xob ncaj qha (tsis txhob nyeem kab lus hauv internet) ua ntej koj pib ua haujlwm. Xav tias cov txheej tiv thaiv ntawm cov kab hluav taws xob tau tawg tawm vim qhov tsis xws luag hauv kev teeb tsa lossis hnub nyoog laus dua. Cov kab uas tsis tau qhwv rau hauv txheej tiv thaiv yuav ua rau hluav taws xob poob. Nws yog lub tswv yim zoo kom muaj ib tus neeg npaj hu lub tsheb thauj neeg mob, yog tias muaj xwm txheej tshwm sim thiab koj xav tau kev pab xwm txheej tam sim. Tus neeg no yuav tsum tau kawm paub txog kev pab ua ntej thiab CPR. Yog tias koj tau ntsib hluav taws xob, tus neeg no yuav xav tshem koj tawm ntawm cov tshuab hluav taws xob siv cov khoom uas tsis siv hluav taws xob, xws li daim ntaub qhuav, los tiv thaiv tus neeg no los ntawm kev raug hluav taws xob. Koj yuav tsum tau sab laj nrog kws tshaj lij hluav taws xob thiab nyeem phau ntawv siv ua ntej ua haujlwm (tsis yog los ntawm kab lus hauv internet) thiab paub hom tam sim no uas yuav ntsib. Clamp cov xov hlau ntawm ib qho taw tes rau tooj liab ntawm lub multimeter. Nco ntsoov tias qhov nthuav tawm ntawm txoj hlua tsis kov koj. Rov pib dua lub ntsuas hluav taws xob thiab kho qhov rhiab ntawm lub ntsuas cua yog tias tsis nyeem tawm los.
Kauj Ruam 6. Tua lub tshuab hluav taws xob hloov thiab siv cov hlau ntxig ntawm AC ntsuas kom paub tseeb tias AC tawm
Tsuas yog hauv qhov no koj tuaj yeem rov ua dua lub zog hluav taws xob. Ua raws li kev ceev faj uas tau teev tseg hauv qib 5 thiab cov neeg siv phau ntawv (thiab tsis yog kab lus hauv is taws nem) tsuas yog qhov xwm txheej. Tom qab nyeem ntawv, kho koj daim phiaj fais fab tawg. Nws muaj kev nyab xeeb dua los yuav thiab teeb tsa cov kab hluav taws xob tshiab dua li txhawm rau thaj chaw txiav.
Lub tswv yim
- Ib txwm nyeem tag nrho cov neeg siv phau ntawv rau kev tiv thaiv kev sib tsoo ua ntej siv lub multimeter.
- Hnav cov hnab looj tes roj hmab thaum ua haujlwm nrog cov kab fais fab.
Ceeb toom
- Hluav taws xob tuaj yeem ua rau hluav taws xob poob thiab tuag taus.
- Tsis txhob ua haujlwm hauv qhov chaw ntub lossis qhov chaw ntub heev. Dej thiab av noo tuaj yeem ua hluav taws xob thiab ua rau koj puas tsuaj.
- Nug ib tus neeg kom muaj nrog lub xov tooj ntawm tes. Txheeb xyuas lub zog mobile thiab teeb liab ua ntej ua haujlwm. Tus neeg no tseem yuav tsum tau kawm paub txog kev pab ua ntej thiab CPR. Tsis txhob cia tus neeg no kov koj ntawm haujlwm.
- Ceev faj nrog koj cov tawv nqaij thiab txawm tias cov khoom ntawm koj cov khaub ncaws zoo li lawv tuaj yeem siv hluav taws xob.
- Ib txwm nyeem phau ntawv qhia hluav taws xob (tsis yog kab lus hauv online) ua ntej cuam tshuam nrog cov khoom siv hluav taws xob lossis tam sim no (tshwj xeeb yog cov ntawv loj).
- Hnav cov hnab looj tes tuab thaum ua haujlwm nrog cov kab hluav taws xob nyob.
- Ib txwm nyeem tag nrho cov neeg siv phau ntawv rau kev ceev faj ua ntej ua haujlwm nrog lub multimeter.
