Kev siv lub tshuab hluav taws xob multimeter txhawm rau txhawm rau txhawm rau pom qhov tsis raug hauv cov teeb pom kev zoo
Thaum cov xau tshwm sim hauv cov teeb pom kev zoo, nws tsis tsuas yog siv hluav taws xob pov tseg xwb, tab sis kuj tseem tuaj yeem ua rau hluav taws xob poob siab. Lub ntsiab lus ntawm kev xau thiab luv luv Circuit Court yog tib yam, tab sis qib ntawm kev sib tsoo txoj kev loj hlob txawv. Kev xau loj tuaj yeem ua rau luv luv. Yog li ntawd, peb yuav tsum tsis txhob coj lub to ntawm lub teeb pom kev zoo circuits maj mam. Kev rwb thaiv tsev ntawm lub voj voog yuav tsum tau kuaj xyuas ntau zaus. Tshwj xeeb tshaj yog thaum pom pom qhov tshwm sim, qhov ua rau yuav tsum tau pom nyob rau lub sijhawm, qhov yuam kev yuav tsum pom, thiab tshem tawm.
Qhov laj thawj tseem ceeb ntawm kev xau hauv cov teeb pom kev zoo yog: ua ntej, kev rwb thaiv tsev ntawm cov xov hlau lossis cov khoom siv hluav taws xob puas tsuaj los ntawm sab nraud; thib ob, kev ua haujlwm ntev ntawm lub voj voog ua rau kev laus thiab kev puas tsuaj ntawm cov rwb thaiv tsev; thib peb, lub Circuit Court yog invaded los ntawm noo noo los yog paug, ua rau tsis zoo rwb thaiv tsev.
Ua ntej, txiav txim siab seb puas muaj qhov xau tiag tiag. Lub rwb thaiv tsev tiv thaiv tuaj yeem ntsuas tau siv R × 10k ntau ntawm tus taw qhia multimeter, lossis digital multimeter tuaj yeem muab tso rau hauv AC tam sim no ntau yam (sib npaug rau ammeter nyob rau lub sijhawm no), txuas nrog hauv series mus rau lub ntsiab hloov, tig rau tag nrho. keyboards, thiab tshem tawm tag nrho cov loads (suav nrog lub teeb teeb). Yog hais tias muaj tam sim no, nws txhais tau hais tias muaj to. Tom qab paub tseeb tias qhov hluav taws xob xau, koj tuaj yeem txuas ntxiv mus xyuas raws li cov kauj ruam hauv qab no.
1. Txiav txim siab seb puas muaj qhov xau ntawm cov kab theem thiab cov kab nruab nrab, cov dej ntws ntawm cov kab theem thiab hauv av, los yog ob qho tib si. Txoj kev yog txiav tawm cov kab nruab nrab. Yog tias qhov ntsuas ammeter tsis hloov, nws txhais tau hais tias muaj qhov xau ntawm theem kab thiab lub ntiaj teb; yog tias qhov ntsuas ammeter yog xoom, nws txhais tau hais tias muaj qhov xau ntawm theem kab thiab kab nruab nrab; Yog tias qhov ntsuas ammeter ua me me tab sis tsis yog xoom, nws txhais tau tias muaj qhov xau ntawm theem kab thiab xoom kab. Muaj cov xaim ntawm cov xaim, theem xaim thiab lub ntiaj teb.
2. Txiav txim siab qhov dej ntws tawm. Tshem lub shunt fuse los yog rub qhib lub Circuit Court breaker. Yog tias qhov ntsuas ammeter tsis hloov, nws txhais tau hais tias lub tsheb thauj mus los; yog tias qhov ntsuas ammeter yog xoom, nws txhais tau tias shunt to; Yog hais tias lub ammeter qhia me me tab sis tsis xoom, nws txhais tau hais tias lub tsheb npav los yog shunt to. Tag nrho cov muaj leakage.
3. Nrhiav qhov to taub. Tom qab kev soj ntsuam saum toj no, tua cov keyboards ntawm lub teeb ntawm kab hauv lem. Thaum ib qho kev hloov pauv tau raug muab tua, qhov taw qhia ammeter rov qab mus rau xoom, uas txhais tau hais tias cov ceg kab yog to; yog tias nws ua me me, nws txhais tau hais tias ntxiv rau qhov to ntawm cov kab no, muaj cov xau rau lwm qhov; Yog tias qhov ntsuas ammeter tseem tsis hloov pauv tom qab txhua lub teeb hloov pauv tau raug tua, nws txhais tau hais tias muaj cov dej xau nyob rau hauv seem ntawm lub cev kab. Los ntawm txoj kev nqaim ntawm qhov kev huam yuaj nyob rau hauv lem, koj tuaj yeem tshawb xyuas ntxiv seb puas muaj cov dej ntws tawm ntawm cov pob qij txha ntawm cov kab no thiab qhov twg cov xov hlau hla ntawm phab ntsa. Tom qab pom qhov to ntawm qhov to, qhov ua txhaum ntawm qhov to yuav tsum raug tshem tawm raws sijhawm. Lub load kawg pib los xyuas cov kauj ruam los ntawm kauj ruam mus rau pem hauv ntej kawg kom pom seb qhov kev ua haujlwm yog tshwm sim los ntawm Circuit Court lossis cov khoom siv, thiab tom qab ntawd koj tuaj yeem txiav txim. Tom qab tshem tawm qhov luv luv Circuit Court txhaum, nruab ib lub fuse tsim nyog ua ntej lub hwj chim.
luv luv Circuit Court, qhib Circuit Court, thiab to ntawm teeb pom kev zoo circuits yog feem ntau faults. Tsuas yog los ntawm kev ua cov kev ntsuas tshwj xeeb thiab kev tshuaj ntsuam xyuas peb tuaj yeem tshawb pom qhov tseeb ntawm qhov txhaum, txiav txim siab qhov txhaum, thiab siv cov kev ntsuas zoo los tshem tawm qhov txhaum sai li sai tau.
