Yuav ua li cas los txheeb xyuas cov luv, tawg, thiab xau nrog multimeter?
Muaj ntau ntau txoj hauv kev los siv lub multimeter, hauv qab no kuv sau cov kev sib txawv los kuaj xyuas qhov luv luv Circuit Court, tawg thiab xau ntawm multimeter, Kuv vam tias nws yuav pab tau koj. Tsis txaus, txais tos ntxiv.
Multimeter check luv Circuit Court
Xyuas seb puas muaj ib qho luv luv Circuit Court hauv kab, ua ntej tshaj, txiav tawm lub Circuit Court breaker, thiab tom qab ntawd tag nrho cov keyboards hauv kab yuav raug kaw, tag nrho cov cuab yeej raug kaw (tuaj yeem yog cov khoom siv unplugged, tag nrho cov unplugged).
Multimeter xaiv "beeping iav", nyob rau hauv lub Circuit Court breaker nyob rau hauv lub qhov ncauj rau kev ntsuas - ob tug cwj mem, raws li, hu rau lub Circuit Court breaker nyob rau hauv lub qhov ncauj ntawm lub xoom kab thiab hluav taws kab. Yog hais tias lub multimeter beeps, ua pov thawj tias muaj ib tug luv luv Circuit Court nyob rau hauv kab; txwv tsis pub, tsis muaj luv luv Circuit Court.
Multimeter check tawg Circuit Court
Tseem txiav tawm tag nrho cov keyboards, lub multimeter xaiv "beeping iav". Txiav txim siab qhov kev taw qhia ntawm txoj kab yuav tsum ntsuas, nrhiav ob qhov kawg ntawm cov hlau.
Kev ntsuas, ob lub cwj mem ntawm lub multimeter tau hu rau ntawm ob qhov kawg ntawm cov hlau, yog tias lub suab beeping, nws ua pov thawj tias tsis muaj qhov tawg ntawm cov hlau; Yog tias tsis muaj lub suab beeping, nws ua pov thawj tias muaj qhov tawg ntawm cov hlau.
Yuav ua li cas yog qhov kev ncua deb ntawm ob kawg ntawm cov hlau nyob deb dhau lawm? Nrhiav ib lub xaim uas tau lees paub tias tsis zoo thiab strip lub xaus ntawm cov hlau. Ib qho kawg ntawm cov hlau txuas nrog lub tshuab multimeter, thiab lwm qhov kawg yog siv los ua tus cwj mem los tiv tauj cov kab yuav tsum tau kuaj - qhov no yog kev siv cov xaim txuas mus rau qhov ntev ntawm tus cwj mem multimeter, txoj hauv kev no feem ntau yuav siv rau hauv xyaum.
Multimeter check leakage
Tsis txhob txiav tawm lub Circuit Court breaker lub sij hawm no, tsuav yog cov kab tawm tag nrho cov keyboards, rub tawm tag nrho cov plugs. Multimeter xaiv "750V ~ iav", nyob rau hauv Circuit Court ntsuas ntsuas (hauv lub qhov (socket), hloov thiab lwm qhov chaw, tsis txhob ntsuas hauv lub thawv faib khoom).
Ntsuas qhov hluav taws xob ntawm kab hluav taws xob - xoom kab thiab kab hluav taws - kab hauv av feem. Yog tias ob qhov kev ntsuas muaj qhov sib npaug, lossis thawj tus nqi tsawg dua qhov thib ob, nws ua pov thawj tias tsis muaj qhov xau hauv kab.
Yog tias tus nqi ntawm thawj qhov kev ntsuas ntau dua qhov thib ob, nws ua pov thawj tias muaj qhov xau hauv kab - qhov ntau dua qhov sib txawv ntawm ob, qhov loj dua qhov to.
