Txoj kev multimeter los nrhiav kev txhaum ntawm hluav taws xob tswj Circuit Court
Ob txoj hauv kev zoo tshaj plaws rau kev daws teeb meem hauv Circuit Court faults nrog multimeter
Ua ntej, txoj kev ntsuas voltage.
Ua ntej, lub voj voog tswj tau hluav taws xob, thiab lub iav hloov ntawm lub multimeter yog teem rau AC voltage ntawm 750V V. Raws li daim duab qhia Circuit Court, ib qho kev sojntsuam ntawm multimeter tau khaws cia ntawm kab 9, thiab lwm qhov kev sojntsuam yog siv los ntsuas kab 8-7-6-5-4-3 raws. Thaum qhov hloov tsis raug kaw, ob qhov kev sojntsuam yog nyob rau tib theem thiab qhov hluav taws xob yog 0 V. Thaum ntsuas kab 2-1, ob lub probes tawm ntawm theem thiab qhov voltage yog 380V V.
Thib ob, txoj kev ntsuas kev tiv thaiv.
Ua ntej tshaj plaws, nws yog ib qho tsim nyog yuav tsum tau txiav tawm Circuit Court, xyuas cov hluav taws xob, thiab tom qab paub tseeb tias tsis muaj hluav taws xob, teeb tsa lub iav hloov ntawm lub multimeter mus rau lub buzzer iav los yog cov iav tiv thaiv, thiab tso ob qhov kev sojntsuam ntawm multimeter. ntawm kab 1 thiab kab 9 raws li: nyob rau hauv ib txwm muaj xwm txheej, nias lub pob SB1 lossis SB2 raws li, lossis ncaj qha nias ob lub AC contactor springs manually (uas yog, manually kaw qhov nquag qhib ntawm KM1 lossis KM2). Lub sij hawm no, 1-9 yog nyob rau, lub Circuit Court yog nyob rau, thiab lub multimeter yuav muaj. Yog tias tsis muaj tus nqi tiv thaiv, nws ua pov thawj tias lub voj voog tsis tuaj yeem, thiab nws yog ib qho tsim nyog los ntsuas thiab txheeb xyuas qhov tshwm sim ntawm qhov taw tes ntawm qhov taw tes tawm tsam daim duab hluav taws xob Circuit Court. Txoj kev ntsuas yog zoo ib yam li qhov voltage.
Thib peb, txoj kev ntsuas kev tiv thaiv thiab ntsuas qhov ntsuas hluav taws xob ntawm multimeter yog ob txoj hauv kev siv ntau tshaj plaws hauv kev daws teeb meem hauv Circuit Court. Nws tuaj yeem hais tias txhua tus muaj nws tus kheej zoo thiab yooj yim. Qhov tseem ceeb yog qhov twg koj tau siv, thiab siv lub multimeter los ntsuas nrog txoj kev koj paub zoo tshaj plaws.
Txoj kev multimeter los nrhiav kev txhaum ntawm hluav taws xob tswj Circuit Court
Feem ntau, muaj txoj kev voltage thiab txoj kev tiv thaiv kom pom kab tsis raug. Txoj kev ntsuas hluav taws xob yog txhawm rau txheeb xyuas qhov ua txhaum ntawm qhov ntsuas hluav taws xob, thiab txoj kev tiv thaiv yog txhawm rau nrhiav qhov txhaum los ntawm kev ntsuas qhov tsis kam. Txhua tus ntawm lawv muaj nws tus kheej zoo. Yog tias koj tsis paub txog kab, peb pom zoo rau txoj kev tawm tsam los txiav txim qhov txhaum, uas yog qhov zoo.
