Multimeter txhawm rau txheeb xyuas qhov tsis raug ntawm lub teeb pom kev zoo
1. Yog vim li cas rau qhov hluav taws xob hluav taws xob Circuit Court
Thaum cov dej xau tshwm sim hauv lub teeb pom kev zoo, nws yuav tsis tsuas yog khib nyiab hluav taws xob xwb, tab sis kuj yuav 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, cov xau ntawm cov teeb pom kev zoo yuav tsum tsis txhob maj maj. Cov rwb thaiv tsev ntawm cov kab yuav tsum tau kuaj xyuas ntau zaus, tshwj xeeb tshaj yog thaum pom cov pa tawm, qhov ua rau yuav tsum tau pom nyob rau lub sijhawm, qhov txhaum yuav tsum pom, thiab nws yuav tsum raug tshem tawm.
Cov laj thawj tseem ceeb ntawm kev xau ntawm 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 kev quab yuam sab nraud; thib ob, kev ua haujlwm ntev ntawm txoj kab ua rau kev laus thiab kev puas tsuaj ntawm cov rwb thaiv tsev;
2. Kev saib xyuas ntawm cov dej xau
Ua ntej txiav txim siab seb puas muaj qhov tso tawm tiag tiag. Siv lub R × 10k block ntawm tus pointer multimeter los ntsuas qhov rwb thaiv tsev ntawm lub ntsuas hluav taws xob, lossis tso cov digital multimeter hauv AC tam sim no thaiv (sib npaug rau ammeter nyob rau lub sijhawm no), txuas nws hauv series mus rau lub ntsiab hloov, tig. ntawm tag nrho cov keyboards, thiab tshem tawm tag nrho cov loads (nrog rau lub teeb teeb). Yog tias muaj tam sim no, nws txhais tau hais tias muaj cov xau. Tom qab paub meej tias qhov xau ntawm txoj kab, koj tuaj yeem txuas ntxiv mus xyuas raws li cov kauj ruam hauv qab no.
(1) Kev txiav txim siab seb nws puas yog qhov xau ntawm theem kab thiab kab nruab nrab, lossis qhov xau ntawm theem kab thiab lub ntiaj teb, lossis ob qho tib si. Txoj kev yog txiav tawm cov kab nruab nrab. Yog tias qhov ntsuas ammeter tseem tsis hloov pauv, nws yog qhov xau ntawm theem kab thiab lub ntiaj teb; yog tias qhov ntsuas ammeter yog xoom, nws yog qhov xau ntawm theem kab thiab kab nruab nrab; Kev xau ntawm kab, theem kab thiab lub ntiaj teb.
(2) Txiav txim siab qhov dej ntws tawm. Tshem tawm lub shunt fuse los yog rub qhib lub Circuit Court breaker. Yog tias qhov ntsuas ammeter tseem tsis hloov pauv, nws txhais tau tias lub tsheb thauj mus los; Yog hais tias lub ammeter qhia yog xoom, nws yog shunt to; Tag nrho cov muaj leakage.
(3) Tshawb nrhiav qhov to taub. Tom qab kev soj ntsuam saum toj no, tua cov hloov ntawm cov teeb thiab cov teeb ci ntawm txoj kab tig. Thaum lub tshuab hluav taws xob raug muab tua, lub ntsuas ntsuas ammeter rov qab mus rau xoom, thiab cov ceg kab yog to; yog tias nws ua me me, nws txhais tau hais tias muaj cov dej ntws tawm hauv lwm qhov chaw ntxiv rau cov ceg kab; Yog tias qhov taw qhia ammeter tseem tsis hloov pauv tom qab txhua lub teeb hloov pauv tau raug muab tua, nws txhais tau hais tias ntu ntawm kab tseem ceeb no tau tawg. Los ntawm kev txo qis ntawm qhov kev huam yuaj nyob rau hauv lem, koj tuaj yeem tshawb xyuas ntxiv seb puas muaj cov xau ntawm cov pob qij txha ntawm txoj kab thiab qhov twg cov xov hlau hla ntawm phab ntsa. Tom qab nrhiav tau qhov dej xau, qhov ua txhaum ntawm cov dej xau yuav tsum raug tshem tawm hauv lub sijhawm.
luv luv Circuit Court, qhib Circuit Court thiab to ntawm teeb pom kev zoo Circuit Court 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.
