Txoj kev rau kev kuaj xyuas xau ntawm lub thawv faib nrog multimeter
Ua ntej siv kev haus tshuaj tiv thaiv hluav taws xob hauv lub txee faib khoom lossis lub thawv ua txhaum thiab cov nta pom tseeb; Tom ntej no, saib xyuas qhov saum npoo rau cov ntsiab lus txhais tau hais, thiab tom qab ntawd mus rau kauj ruam tom ntej ntawm kev kuaj xyuas.
1. Ua ntej, disconnect lub ntsiab lus rov qab los ntawm peb lub zog cov kab ntawv tuaj koom thiab tua txhua qhov hluav taws xob plug, tu taub dej hloov chaw, thiab lwm yam.
2. Place the gear of the digital multimeter in the 200M range of the ohm range, place one probe on one of the two output lines on the load side, and touch the other probe against the wall, preferably the grounding wire or temporary grounding wire. Tom qab tus lej pom ntawm cov cabiltimy ntau, cov rwb thaiv tsev tsis kam lees tus nqi ntawm lub circuit Court tseem nyeem. Yog tias cov rwb thaiv tsev tsis kam nqi yog tsawg dua 0.5 Moohms, ces muaj teeb meem nrog lub circuit Coillcuit Court. Yog tias cov rwb thaiv tsev tsis kam muaj siab dua 0.5 Moohms, ces nws tuaj yeem raug txiav txim tawm tias muaj teeb meem nrog lub circuit Court. Ntsuas lwm tus hlau siv tib txoj kev thiab kos tus nqi kom pom yog tias muaj teeb meem nrog lub circuit Court.
3. Tshawb xyuas lub rwb thaiv tsev tsis kam lees qhov tseem ceeb ntawm cov ceg thiab ntau txoj kev siv hluav taws xob, thiab siv tib txoj kev los xyuas lawv ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho kev txhaum taw tes yog pom.
Kev Ceev Kev Ua Haujlwm
Thaum siv cov mulleatusatuses nyob rau hauv xyoo 200M, ceev faj ntau tsis txhob kov cov hlau ntawm cov kev sojntsuam nrog koj txhais tes thaum ntsuas, qhov no yuav ua rau nyeem tsis raug.
2. Thaum ntsuas cov khoom siv hluav taws xob ntau ntau, ua tib zoo saib xyuas kom tsis txhob muaj peev xwm tiv thaiv cov khoom siv los ntawm cov neeg raug mob.
Hom no yog ib txoj kev muaj kev nyab xeeb los nrhiav qhov kev ua txhaum hauv lub xeev tsis muaj hluav taws xob. Hom no tseem siv tau rau kev tshawb nrhiav cov siv fais fab thiab lub Hoobkas xau, tab sis thaum lub sij hawm tshawb nrhiav, tab sis kuj yog cov kab nruab nrab yuav tsum tau txiav kom tsis txhob muaj hluav taws xob sib tsoo.
