Yuav ua li cas siv ib tug multimeter los xyuas cov luv luv Circuit Court thiab to hauv koj lub tsev
1. Kev ntsuas luv luv ntsuas lub hauv paus ntsiab lus luv luv yog qhov yooj yim tuaj yeem ntsuas nrog lub zog tiv thaiv, tab sis nrog lub suab ntawm hom digital multimeter yog qhov zoo dua, ntaus lub diode iav yog qhov zoo tshaj plaws rau unplug tag nrho cov khoom siv hluav taws xob hauv tsev. , ntaus tus hloov thiab ces nrhiav ib tug plug rau tus cwj mem tso Yog hais tias muaj ib tug luv luv Circuit Court nyob rau hauv kab lub multimeter yuav tso tawm beep .... Yog hais tias muaj ib tug luv luv Circuit Court nyob rau hauv kab, lub multimeter yuav tso ib tug beep suab; yog tias cov kab nws tus kheej tsis luv luv, ces txuas cov khoom siv ib qho los ntawm ib qho los saib seb puas muaj qhov luv luv hauv cov khoom siv ntawd.
2. txoj kab xau yog qhov nyuaj dua rau kev ntsuas, tab sis koj tuaj yeem ntsuas qhov kev tiv thaiv ntawm cov kab rau hauv av Cov khoom xau, ces cov xoom xoom xaim lossis hluav taws xob xaim yuav raug txuas nrog lub plhaub (twb grounded plhaub) lossis cov rwb thaiv tsev tsis zoo tuaj yeem ntsuas los ntawm cov ntaub ntawv tiv thaiv
Qee lub sij hawm kev tshuaj xyuas qhov muag kuj tuaj yeem pom, xws li qee cov khoom siv hluav taws xob lossis cov xaim hluav taws xob los ntawm ib puag ncig qhov chaw ntub dej ntau tuaj yeem cuam tshuam hluav taws xob tuaj yeem tsim nyog pad qee yam qhuav kom cais nws. Tsis tas li ntawd, koj tuaj yeem tshem tawm tag nrho cov khoom siv hluav taws xob thiab txuas lawv ib qho los ntawm ib qho, tom qab ntawd koj tuaj yeem nrhiav cov khoom xau.
Lub luv luv Circuit Court yog ib qho kaw Circuit Court uas cov khoom siv hluav taws xob txuas ncaj qha los ntawm cov xaim tsis dhau los ntawm kev thauj khoom. Lub zog hluav taws xob hauv kev ua haujlwm, theem mus rau theem lossis theem mus rau hauv av (lossis nruab nrab) nruab nrab ntawm kev sib txuas txawv txav (xws li luv luv Circuit Court) thiab ntws los ntawm cov tam sim no loj heev. Raws li ib txwm muaj, qhov kev tiv thaiv ntawm theem thiab theem lossis theem thiab hauv av yog qhov loj heev, luv luv Circuit Court, nws qhov tsis kam yog xoom, nrog rau multimeter los ntsuas qhov tsis kam tuaj yeem ua tiav. Qhov kev ntsuas no, lub xeev conductive yog qhov nyuaj kom muaj lub sijhawm los ntsuas, tab sis lub Circuit Court tsis nyob rau hauv lub xeev yog qhov zoo heev los ntsuas qhov kev txiav txim.
Thaum lub Circuit Court tsis kaw, los yog cov hlau tsis txuas, uas yog, lub Circuit Court yog tawg rau ib qho chaw. Nyob rau hauv lub xeev ntawm Circuit Court yog hu ua ib tug tawg Circuit Court, kuj hu ua qhib Circuit Court. Thaum ntsuas nrog lub multimeter, nws cov yam ntxwv tseem ceeb yog qhov tsis muaj qhov tsis kam.
Leakage yog lub plhaub ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob vim qee qhov laj thawj txuas rau hauv av thiab hauv av ntawm qee qhov sib txawv. Txoj hauv kev zoo tshaj plaws los kuaj xyuas cov dej xau yog siv tus cwj mem hluav taws xob los tiv tauj lub cev, yog tias lub teeb neon npuas tam sim ntawd tawm mus, ua pov thawj tias lub cev them nrog hluav taws xob zoo li qub; yog tias qhov ntev ci tsau to yog undoubtedly.
Xav tias cov kab xau, qhov ua tau xau taw qhia ncaj qha rau hauv av ntsuas ntsuas, yog tias qhov hluav taws xob thiab AC voltage ze rau qhov to. Koj tuaj yeem ntsuas qhov tsis kam, tab sis qhov kev ua haujlwm tsis yooj yim li ntsuas qhov voltage.
