Yuav ua li cas txheeb xyuas ballast nrog multimeter
Txheem
Lub tshuab hluav taws xob hluav taws xob, tseem hu ua lub tshuab hluav taws xob, yog ib qho khoom siv uas txwv cov khoom siv tam sim no xws li cov teeb lossis cov teeb fluorescent. Yog tias koj khiav mus rau ib qho teeb meem nrog nws, koj tuaj yeem sim nws yooj yim nrog lub digital lossis analog multimeter.
Lub tshuab hluav taws xob digital muaj zog ntau dua li analog multimeter thiab yuav tso cai rau koj kom pom DC thiab AC voltage, hloov pauv tam sim no, thiab kev ntsuas digital siab. Nws tau muab faib ua 4 ntu: cov duab digital, tswj hwm, hu xov tooj thiab cov khoom nkag. Nws muab cov txiaj ntsig tseem ceeb hauv kev nyeem kom raug nrog xoom parallax yuam kev.
Teem lub DMM rau XNUMX ohms. Tom qab ntawd txuas cov hlau dub rau hauv av dawb ntawm lub ballast. Tshawb xyuas txhua lub xov hlau nrog ib qho kev sojntsuam liab. Yog tias koj lub ballast zoo, nws yuav rov qab qhib lub voj lossis kev nyeem ntawv siab tshaj plaws.
Yuav ua li cas thiaj nrhiav tau qhov phem ballast?
Ballast yog tsim nyog los muab cov hluav taws xob tsim nyog rau cov khoom siv hluav taws xob xws li cov teeb fluorescent. Lub ballast yog lub luag hauj lwm rau muab qhov hluav taws xob rau lub teeb qhov muag teev thiab txo qhov tam sim no mus rau qib qub thaum hluav taws xob tsim los ntawm lub teeb ci. Yog tias tsis muaj qhov tsim nyog ballast, lub teeb fluorescent tuaj yeem hlawv tawm vim 120 volts ntawm qhov tam sim no. Tshawb xyuas lub ballast yog tias koj hnov lub suab nrov ntawm cov khoom siv los yog lub teeb pom kev zoo. Koj tuaj yeem tshawb pom qhov no los ntawm kev ua cov hauv qab no. (1)
Cov txheej txheem kuaj
Txoj kev no siv sijhawm tsawg dua thiab muab qhov tseeb ballast xeem. Ntawm no kuv yuav hais txog cov kauj ruam rau kev kuaj lub ballast nrog ib tug multimeter.
- Tua lub Circuit Court breaker
- Tshem tawm Ballast
- Teem lub teeb tsa tsis kam ntawm multimeter (Rau cov neeg pib tshiab, nyem qhov no kom paub suav ohms ntawm multimeter)
- Txuas lub multimeter sojntsuam rau cov hlau
- Reinstallation
1. Tua lub Circuit Court breaker
Nco ntsoov tua lub Circuit Court breaker ua ntej pib ua haujlwm hluav taws xob. Tua tawm qhov hloov pauv thiab hloov pauv txuas nrog cov khoom siv hluav taws xob uas koj xav sim.
2. Tshem lub ballast
Cov tshuab sib txawv muaj qhov chaw sib txawv. Cov ballasts txuas nrog lub qhov muag teev, yog li tshem lub teeb raws li qhov chaw muab los ntawm cov chaw tsim khoom. U-puab qhov muag teev yog txuas nrog lub caij nplooj ntoos hlav nro, thiab cov qij puag ncig txuas nrog lub qhov (socket) nrog rau cov ballast. Koj muaj peev xwm rho tawm lawv clockwise los yog counterclockwise.
3. Multimeter kuj teeb tsa
Teem lub DMM rau XNUMX ohms. Yog tias koj siv Cen-Tech DMM, ntawm no yog cov lus qhia yuav ua li cas siv nws los xyuas qhov voltage.
4. Txuas lub multimeter sojntsuam rau cov hlau.
Tom qab ntawd koj tuaj yeem ntxig tus tshiab multimeter coj mus rau hauv cov hlau txuas. Xaiv tus uas tuav cov xov hlau dawb. Koj tuaj yeem khi cov kev sojntsuam ntxiv rau cov xov hlau liab, daj thiab liab uas tuaj ntawm ballast. Lub multimeter yuav rov qab siab tshaj qhov tsis kam, piv txwv li xoom tam sim no dhau ntawm qhov hnav hauv av thiab lwm tus, thiab yuav txav mus rau sab xis ntawm multimeter yog tias lub ballast zoo. Txawm li cas los xij, yog tias nws pom qhov nruab nrab tam sim no, tsis muaj lwm txoj kev xaiv tab sis hloov nws.
5. Rov nruab
Yog tias tsim nyog, koj tuaj yeem nruab ib lub ballast tshiab. Tom qab hloov, teeb lub teeb fluorescent thiab hloov lawv nrog lub lens cap. Tig lub zog rov qab khawm ntawm lub vaj huam sib luag luam tawm kom qhib lub ntsuas.
