Multimeter test socket (2-txoj kev xeem)
Txheem
Koj puas muaj ib qho analog lossis digital multimeter tab sis tsis paub siv nws los ntsuas qhov hluav taws xob? Nrog peb cov lus qhia rau kev ntsuas qhov hluav taws xob nrog multimeter, koj yuav kawm txhua yam koj xav paub. Yog tias koj txhawj xeeb tshaj plaws txog cov kab hluav taws xob, peb tau txais koj them.
Hauv luv luv, koj tuaj yeem tawm nrog multimeter los ntawm kev ua raws li cov kauj ruam no. Ua ntej, teeb tsa koj lub multimeter kom tsim nyog rau ntsuas qhov voltage. Tom qab ntawd txuas lub plug dub rau COM chaw nres nkoj thiab lub ntsaws liab rau Omega chaw nres nkoj. Tom qab ntawd ntxig qhov kev sojntsuam mus rau hauv ob txoj kab ntsug ntawm lub qhov hluav taws xob. Muab tus liab tso rau hauv qhov me me thiab qhov dub rau hauv qhov loj. Cia siab tias qhov kev nyeem ntawv ntawm 110-120 volts rau lub qhov hluav taws xob ua haujlwm zoo. Tsis muaj kev nyeem ntawv txhais tau hais tias lub qhov (socket) wiring faulty los yog Circuit Court breaker tau tripped.
Checkout Cov txiaj ntsig
- Qhov no pab kom lub chassis ruaj ntseg.
- Qhov no yuav pab koj txiav txim siab yog tias cov xaim hauv qhov hluav taws xob thim rov qab.
yam nto moo
Nco ntsoov nyeem phau ntawv qhia uas tuaj nrog koj cov digital lossis analog multimeter. Tsis txhob kov cov hlau pins kom tsis txhob muaj hluav taws xob poob. Txheeb xyuas qhov voltage ntawm qhov hluav taws xob hluav taws xob yog qhov yooj yim heev. Ua rau nws, koj tuaj yeem paub tseeb tias nws lub cev muaj kev nyab xeeb.
Cov lus qhia ib kauj ruam dhau-kauj ruam rau kev ntsuas qhov hluav taws xob nrog multimeter
Peb tau siv ob txoj hauv kev los ntsuas qhov tso zis ntawm multimeter, uas yog;
- Thawj txoj kev - Tshawb xyuas qhov hluav taws xob hauv lub qhov (socket).
- Qhov ob -Chassis grounding check
Wb mus tam sim no.
Txoj Kev 1: Tshawb xyuas qhov hluav taws xob ntawm qhov hluav taws xob
1. Paub koj tus kheej nrog qhov hluav taws xob qhov hluav taws xob toj roob hauv pes. Niaj hnub nimno sockets muaj peb lub qhov - kub, nruab nrab thiab hauv av. Qhov qis dua yog ib lub voj voos kheej kheej. Qhov nruab nrab yog qhov ntev dua rau koj sab laug thiab kub yog qhov luv luv rau koj sab xis. Kov txhua qhov nrog kev saib xyuas vim tias peb lub xov hlau tuaj yeem tswj tau qhov tam sim no. (1)
2. Nruab ib qho analog lossis digital multimeter. Teem koj lub multimeter raws li qhov ntsuas voltage. Koj puas pom kab wavy? Qhov no yog ib qho kev ua haujlwm tam sim no (AC). Xaiv nws. Nov yog cov lus qhia ntxaws ntxiv txog kev ntsuas qhov voltage nrog multimeter.
3. Txuas cov xov hlau. Lub dub hlau txiv tsawb plug (luv tuab plug) yuav tsum haum rau hauv lub jack sau npe "COM". Ib txhia feem ntau muaj ib tug kos npe rau ib sab ntawm lawv. Tom qab ntawd txuas lub connector liab nrog lub cim zoo (+) lossis omega, tsab ntawv Greek. (2)
4. Ntsuas qhov hluav taws xob ntawm qhov hluav taws xob. Nrog ib txhais tes, ntxig qhov kev sojntsuam mus rau hauv ob txoj kab ntsug ntawm lub qhov hluav taws xob. Muab tus liab tso rau hauv qhov me me thiab qhov dub rau hauv qhov loj. Cia siab tias qhov kev nyeem ntawv ntawm 110-120 volts rau lub qhov hluav taws xob ua haujlwm zoo. Tsis muaj kev nyeem ntawv txhais tau hais tias lub qhov (socket) wiring faulty los yog Circuit Court breaker tau tripped.
Txoj Kev 2: Xyuas kom tseeb tias lub qhov hluav taws xob yog qhov zoo
Cia cov hlau liab nyob rau hauv lub qhov (socket) me me thiab txav cov hlau dub mus rau hauv lub qhov (socket) hauv av. Kev nyeem ntawv volt yuav tsum tsis txhob hloov pauv (nruab nrab ntawm 110 thiab 120). Yog tias qhov kev nyeem ntawv hloov pauv, qhov no qhia tias kev sib txuas hauv av tsis raug.
Los ntawm kev txheeb xyuas tias lub qhov hluav taws xob yog hauv av kom zoo, koj tuaj yeem xyuas kom meej tias cov xaim tsis thim rov qab. Txav qhov kev sojntsuam liab mus rau qhov loj thiab qhov kev sojntsuam dub mus rau qhov me me. Cov xaim yuav thim rov qab yog tias koj tau txais kev nyeem ntawv ntawm DMM. Txawm hais tias qhov teeb meem no yuav tsis cuam tshuam nrog cov khoom siv hluav taws xob yooj yim xws li teeb, nws tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob ntau dua.
Summing txog
Tshawb xyuas lub qhov hluav taws xob rau qhov hluav taws xob, seb nws puas yog hauv av, thiab seb cov xaim puas rov qab yog qhov tseem ceeb rau kev nyab xeeb ntawm koj lub tsev lossis chaw ua haujlwm. Tsis muaj kev koom nrog ib tus engineer lossis electrician, muaj peev xwm ua qhov no yog qhov ntxiv. Hmoov zoo, koj tuaj yeem ua qhov no nrog analog lossis digital multimeter.
