Yuav ua li cas xyuas yog tias ib lub xov hlau kub nrog lub multimeter
Txheem
Txawm hais tias koj tab tom yuav ua haujlwm nrog cov hluav taws xob hluav taws xob lossis tsuas yog xav nkag siab tias lawv ua haujlwm li cas, lub xov hlau kub lossis nyob yog ib qho tseem ceeb tshaj plaws uas yuav tsum tau saib xyuas.
Cov hlau kub yog ib qho los ntawm qhov hluav taws xob tam sim no dhau mus tas li.
Tsawg tus neeg paub yuav ua li cas txheeb xyuas nws, thiab nrog cov xov hlau ntawm tib xim, nws yuav nyuaj dua.
Hmoov zoo, koj tau tuaj rau qhov chaw zoo.
Peb piav qhia tag nrho cov txheej txheem ntawm yuav ua li cas los xyuas seb cov hlau puas kub nrog lub tshuab multimeter.
Cia peb pib.
Yuav ua li cas xyuas yog tias ib lub xov hlau kub nrog lub multimeter
Teem lub multimeter mus rau 250VAC ntau yam, tso cov hlau kuaj liab rau ntawm ib qho ntawm cov xov hlau, thiab tso cov hlau kuaj dub rau hauv av. Yog hais tias cov hlau yog kub, lub multimeter qhia 120 los yog 240 volts, nyob ntawm seb lub hwj chim tso zis.
Cov txheej txheem yog qhov yooj yim heev, tab sis tsis yog txhua yam.
- Hnav tiv thaiv
Thaum koj sim kom pom tias cov hlau yog kub, koj twv yuav raug hu xav tias tam sim no ntws los ntawm nws.
Kev raug hluav taws xob yog ib yam uas koj tsis xav tau, yog li muab cov roj hmab tiv thaiv los yog cov hnab looj tes insulating ua ntej koj nkag mus rau hauv.
Koj kuj hnav looj tsom iav dub thaum muaj hluav taws kub, tuav koj txhais tes ntawm cov yas lossis roj hmab ib feem ntawm lub tshuab ntsuas qhov ntsuas, thiab khaws cov xov hlau tsis txhob kov ib leeg.
Raws li ib tug beginner, koj cob qhia nrog de-energized xov hlau kom tsis txhob yuam kev.
- Teem lub multimeter rau 250V AC ntau yam
Koj cov khoom siv hluav taws xob hloov pauv tam sim no (AC voltage) thiab koj teeb tsa koj lub ntsuas ntsuas rau nws qhov siab tshaj plaws kom tau txais kev nyeem ntawv tseeb tshaj plaws.
Qhov 250VAC ntau yog qhov zoo vim tias qhov siab tshaj qhov hluav taws xob koj xav tau los ntawm cov khoom siv thiab cov hluav taws xob hluav taws xob yog 240V.
- qhib tawm
Txhawm rau txheeb xyuas qhov twg ntawm cov xov hlau hauv qhov hluav taws xob kub, koj yuav tsum qhib lub qhov hluav taws xob.
Tsuas yog tshem tawm tag nrho cov ntsia hlau tuav cov khoom ua ke thiab rub tawm cov xov hlau.
Feem ntau muaj peb cov xov hlau hauv lub qhov (socket): theem, nruab nrab thiab hauv av.
- Muab cov sensors rau ntawm cov xov hlau
Feem ntau tsuas yog cov hlau nyob lossis kub kub yuav tuav tam sim no thaum nws qhib, thiab qhov no ua rau tag nrho cov kev sim no yooj yim dua.
Muab cov xim liab (zoo) coj mus kuaj rau ntawm ib lub xaim thiab cov xim dub (tsis zoo) kuaj ua rau hauv av.
- Ntsuas cov txiaj ntsig
Tom qab koj tso koj cov kev sojntsuam, koj xyuas cov ntawv nyeem multimeter.
Yog hais tias lub multimeter nyeem 120V (nrog teeb pom kev zoo nyob ntawm tej) los yog 240V (nrog rau cov khoom siv loj), cov hlau yog kub los yog nyob.
Nco ntsoov tias cov hlau kub yog ib qho nrog cov tshuaj ntsuam liab thaum koj tau txais qhov kev nyeem ntawv no.
Qhov kev sojntsuam dub tseem nyob hauv av.
Lwm cov xov hlau (nruab nrab thiab hauv av) qhia xoom tam sim no nyeem.
Siv daim ntawv los yog daim kab xev npog los kos cov hlau kub kom koj tuaj yeem txheeb xyuas tau yooj yim rau yav tom ntej.
Ntawm no yog ib daim vis dis aus uas qhia meej yuav ua li cas txiav txim siab cov hlau kub nrog multimeter:
Yog tias koj tsis tau txais kev nyeem ntawv multimeter, qhov teeb meem yuav yog nrog cov xov hlau. Peb muaj ib tsab xov xwm hais txog kev nrhiav cov xov hlau nrog lub multimeter.
Muaj lwm txoj hauv kev los txiav txim siab seb cov hlau twg kub.
Siv lub ntsuas hluav taws xob tsis sib cuag
Ib txoj hauv kev yooj yim dua thiab muaj kev nyab xeeb dua los txiav txim siab seb cov hlau twg kub yog siv lub ntsuas hluav taws xob tsis sib cuag.
Lub ntsuas hluav taws xob tsis sib cuag yog ib qho khoom siv uas teeb pom kev thaum muaj hluav taws xob siv rau nws. Nws yuav tsum tsis txhob kov cov hlau liab qab.
Txhawm rau xyuas seb lub xov tooj puas nyob, tsuas yog tso qhov ntxeev ntawm qhov ntsuas hluav taws xob tsis sib cuag ntawm cov xaim lossis qhov hluav taws xob.
Yog hais tias lub teeb liab (los yog lwm yam teeb, nyob ntawm seb tus qauv) yog nyob rau, lub xaim los yog chaw nres nkoj kub.
Qee qhov ntsuas hluav taws xob tsis sib cuag tau tsim los ua suab nrov thaum nyob ze ntawm qhov hluav taws xob.
Thaum lub cuab yeej no muaj kev nyab xeeb dua rau kev siv, lub multimeter yog ntau yam cuab yeej rau kev sim lwm yam khoom siv hluav taws xob.
Koj tuaj yeem xaiv siv lub multimeter los xyuas seb cov hlau twg yog nruab nrab thiab qhov twg yog hauv av.
Siv cov lej xim
Lwm txoj hauv kev los qhia tias cov hlau twg kub yog siv cov xim xim.
Txawm hais tias txoj kev no yog qhov yooj yim tshaj plaws, nws tsis yog qhov tseeb lossis muaj txiaj ntsig zoo li lwm txoj hauv kev.
Qhov no yog vim ntau lub teb chaws siv cov xim xim sib txawv thiab qee zaum txhua cov xov hlau tuaj yeem yog xim tib yam.
Thov xa mus rau lub rooj hauv qab no txhawm rau txiav txim siab cov lej xim rau koj lub tebchaws.
Ib-theem ib-theem kab yog ib tug nyob los yog energized hlau.
Raws li koj tuaj yeem pom, cov lej xim tsis yog universal thiab tsis tuaj yeem tso siab rau tag nrho.
xaus
Kev txiav txim siab qhov twg ntawm koj cov xov hlau kub yog ib txoj hauv kev yooj yim tshaj plaws.
Ua tib zoo saib, koj tsuas yog siv multimeter los xyuas qhov kev nyeem ntawv voltage.
Yog tias nws muaj txiaj ntsig, koj tuaj yeem tshawb xyuas peb cov khoom ntawm kev sim lwm yam khoom siv hluav taws xob nrog multimeter.

Cov hlau twg kub yog ob qho tib si xim?
Cov hlau kub qhia tau hais tias qhov kev nyeem ntawv multimeter thaum kuaj. Koj sim los ntawm kev tso lub xov tooj liab rau ntawm cov xov hlau thiab muab qhov kev sojntsuam dub rau hauv av kom tau txais kev nyeem ntawv ntawm 120VAC lossis 240VAC.
Yuav ua li cas koj sim ib tug kub hlau rau hauv av?
Txhawm rau ntsuas cov hlau kub rau hauv av, koj yuav xav tau ib lub multimeter. Muab cov hlau kuaj liab tso rau ntawm ib lub xaim thiab tso cov hlau kuaj dub rau hauv av. Cov hlau kub qhia tau hais tias kev nyeem ntawv ntawm 120VAC lossis 240VAC.
Yuav ua li cas kom paub tseeb tias lub hwj chim tawm nrog ib tug multimeter?
Teem lub multimeter mus rau qhov siab tshaj plaws AC voltage ntau, tso cov hlau kuaj liab rau ntawm cov hlau thiab cov hlau lead dub rau hauv av. Yog tias koj lub hwj chim tawm, lub multimeter tsis qhia qhov kev nyeem ntawv voltage.
