Txoj kev ntsuas luv luv Circuit Court, qhib Circuit Court, thiab leakage ntawm Circuit Court nrog ib tug multimeter
Ib tug multimeter feem ntau yog siv. Tshooj lus no yuav piav qhia txog yuav ua li cas ntsuas qhov luv luv Circuit Court, qhib Circuit Court, thiab teeb meem ntawm qhov hluav taws xob hauv Circuit Court, thiab yuav ua li cas ntsuas luv luv Circuit Court thiab qhib Circuit Court nrog multimeter tom qab ib qho kev mus ncig hauv Circuit Court.
1. Kev ntsuas luv luv nrog lub ntsuas ntsuas
Txoj kev ua haujlwm:
Ntxig cov hlau lead dub ntawm lub multimeter rau hauv lub qhov "com" thiab cov hlau lead liab rau hauv "V Ω" qhov, thiab kho cov pob qhov rooj mus rau qhov chaw beep.
Disconnect lub hwj chim mov ntawm lub xeem Circuit Court thiab ntsuas ob lub xov hlau ntawm lub Circuit Court nrog ob probes. Yog hais tias lub multimeter qhia qhov tsis kam ntawm 0 thiab muaj lub suab nrov, nws qhia tau hais tias luv luv hauv Circuit Court.
Xwb, siv Ohm 1k lossis 10k los txiav tawm lwm qhov kawg ntawm txoj kab thiab sim ob lub xov hlau nrog ob qhov kev sojntsuam. Yog hais tias lub multimeter qhia ib tug tsis kam ntawm 0, nws qhia ib tug luv luv Circuit Court nyob rau hauv kab.
2. Multimeter xeem rau qhib Circuit Court
Txoj kev ua haujlwm:
Thaum kuaj qhov txuas ntxiv ntawm lub voj voog, nws yog qhov tsim nyog yuav tsum tau txiav lub hwj huam mov ua ntej kuaj.
Tig lub pob qhov rooj mus rau txoj hauj lwm beep, thiab sim tias ob qho kawg ntawm lub voj voog yog nyob rau hauv kev sib cuag nrog cov hlau koob ntawm qhov kev sojntsuam. Yog tias muaj qee yam tsis kam thiab lub suab nrov, nws qhia tau hais tias lub Circuit Court yog conductive; Yog tias qhov kev tiv thaiv tsis kawg, tso tawm raws li 1, thiab tsis muaj beep, ces kab yog txiav.
Xwb, xaiv 10k iav nrog multimeter thiab luv Circuit Court lwm kawg ntawm kab. Siv lub multimeter's sojntsuam los kuaj ob kab. Yog hais tias lub multimeter qhia qhov tsis kam ntawm 1, nws qhia tau hais tias qhib Circuit Court; Tso tawm raws li 0, nws muaj peev xwm hais tias lub voj voog ua haujlwm.
3. Kev ntsuas qhov dej tawm nrog lub Multimeter
Muaj cov xau hauv Circuit Court, thiab feem ntau nws tsis pom zoo kom siv lub tshuab multimeter rau kev sim. Nws kuj tseem tuaj yeem siv multimeter thaum tsis muaj lwm yam kev ntsuas.
Txoj kev ua haujlwm:
Tig lub multimeter mus rau AC voltage ntau, ua ntsuas nyob, thiab ntsuas cov hlau casing ntawm cov cuab yeej xav tias yuav to.
Thaum ntsuas, ib qho kev sojntsuam txuas nrog lub casing thiab lwm qhov kev sojntsuam yog grounded. Yog tias qhov tso tawm voltage siab dua 30V, sim dua. Yog tias cov khoom siv hluav taws xob tau lees paub tias siab dua 30V, nws qhia tau tias xau. Yog tias nws qis dua 30V, nws feem ntau yog qhov qub. Koj tuaj yeem kho tus cwj mem taub hau ntawm xoom thiab nyob hlau ntsuas thiab ntsuas lawv ib zaug los txiav txim.
Cov ntsiab lus
Siv ib lub ntsuas ntsuas los ntsuas qhov luv luv, qhib circuits, AC voltage, DC voltage, tsis kam, tam sim no, thiab lwm yam.
Lus Cim: Tus cwj mem liab yog qhov zoo thiab tus cwj mem dub yog qhov tsis zoo. Thaum ntsuas, ntsuas qeb thiab ntau yam yuav tsum tau kuaj ua ntej. Thaum qhov ntau yam tsis tuaj yeem kwv yees, xaiv qhov loj dua ua ntej, thiab tom qab ntawd maj mam hloov mus rau qhov me me raws li tus nqi.
