Yuav ua li cas siv ib tug multimeter los xyuas qhib Circuit Court thiab luv Circuit Court
Ua ntej txuas cov kev xeem coj mus kuaj, kev xaiv ntawm multimeter tuaj yeem yog tus taw tes lossis cov duab digital, cov hlau kuaj liab tau muab tso rau hauv cov ntaub ntawv VΩ, thiab cov hlau lead dub tau muab tso rau hauv COM davhlau ya nyob twg los xyuas kom meej tias lub multimeter yog qhov qub; tig lub iav multimeter, thiab siv cov ntaub ntawv tiv thaiv los ntsuas luv luv lossis qhib Circuit Court, xws li 200Ω cov ntaub ntawv; txuas qhov kev xeem coj mus rau ob qho kawg ntawm kab, yog tias lub multimeter tsis tso tawm (duab 1), nws txhais tau hais tias qhib Circuit Court, thiab yog tias nws qhia me me ntawm 0 o'clock, nws txhais tau tias luv luv Circuit Court.
Tsis txhob siv lub multimeter los ntsuas qhov to. Lub hwj chim ntawm lub multimeter feem ntau yog 9V roj teeb. Tsawg voltage tsis txhais hais tias 220 high voltage tsis xau. Nws yuav tsum tau ntsuas nrog lub shaker tsawg kawg yog 500V. Ob lub clamps ntawm lub shaker txuas nrog 2 kawg ntawm kab. Kov, tus pointer ntawm lub meter taub hau khiav mus rau xoom kev taw qhia, uas yog to.
Peb lub ntsiab lus ntawm Circuit Court muaj pes tsawg leeg yog fais fab mov, load, thiab nruab nrab txuas. Lub hwj chim mov yog ib yam khoom uas muab hluav taws xob rau lub load, thiab lub load yog ib tug ntaus ntawv uas tau txais hluav taws xob lub zog thiab hloov mus rau lwm yam zog. Qhov hloov hauv nruab nrab txuas yog qhib lossis tawm ntawm lub voj voog, thiab cov xaim xaim hluav taws xob.
Yooj yim muab, luv luv Circuit Court yog qhov tsis muaj load, thiab tsuas muaj ob lub ntsiab lus, lub hwj chim mov thiab qhov nruab nrab txuas. Qhov qhib Circuit Court tsis muaj qhov sib txuas nruab nrab, tsuas yog ob lub ntsiab lus ntawm lub zog thiab kev thauj khoom, xws li qhov hloov pauv tsis raug kaw thiab cov xaim raug kaw. Leakage yog tam sim no to ntawm cov khoom nyob los yog cov khoom siv vim kev laus ntawm cov txheej insulating los yog lwm yam laj thawj. Rau qee qhov laj thawj, muaj qee qhov muaj peev xwm sib txawv ntawm cov av thiab hauv av, uas yog cov xau. Yog li ntawd, cov dej xau tuaj yeem tshwm sim hauv cov khoom siv hluav taws xob, kev thauj khoom, lossis kev sib txuas nruab nrab.
Multimeter check luv Circuit Court, qhib Circuit Court, to
Tshawb xyuas qhov ua txhaum luv luv thiab qhib-circuit nrog txoj kev ntsuas kev tiv thaiv lossis xyuas qhov luv luv thiab qhib-circuit faults nrog lub buzzer iav.
Thaum siv multimeter los xyuas cov luv luv Circuit Court thiab qhib circuits, siv txoj kev tiv thaiv kev tiv thaiv los txiav txim seb lub zog hluav taws xob puas raug txiav tawm. Thaum kuaj xyuas cov load lossis kab, xaiv cov iav tiv thaiv tsim nyog. Nws pom tias qhov kev nyeem ntawv ntawm multimeter yog xoom, thiab lub iav ntawm multimeter yog qis dua. Yog tias qhov kev nyeem ntawv tseem yog xoom, yuav tsum muaj luv luv. Nws tau pom tias qhov kev nyeem ntawv qhia cov cim hla "1", thiab lub cim hla "1" tseem tshwm sim tom qab cov iav tiv thaiv tau hloov kho upwards. Yuav tsum muaj qhov qhib Circuit Court. Txheeb xyuas qhov luv luv thiab qhib Circuit Court nrog lub buzzer iav ntawm lub multimeter, thiab lub hauv paus yog txiav tawm lub zog hluav taws xob. Thaum lub sij hawm sim, nws tau pom Lub multimeter beeps, nws yuav tsum yog luv luv Circuit Court. Yog tias lub cim overflow 1 tau tshwm sim, nws tsis tas yuav yog qhib Circuit Court. Nyob rau lub sijhawm no, txuas ntxiv ntsuas nrog lub siab tiv thaiv iav ntawm multimeter. Yog tias lub cim overflow 1 tseem tshwm sim, nws txhais tau hais tias muaj qhov qhib Circuit Court.
Multimeter los xyuas cov dej xau
Raws li cov lus piav qhia ntawm cov dej xau, nws tuaj yeem pom tias vim qhov kev laus ntawm cov txheej txheem rwb thaiv tsev ntawm cov khoom thauj, cov khoom siv hluav taws xob, thiab kev sib txuas nruab nrab lossis lwm yam, yuav muaj qhov sib txawv ntawm peb lub ntsiab lus saum toj no thiab lub ntiaj teb. Yog tias nws tau kuaj pom nrog lub xaum ntsuas, nws lub raj neon yuav twv yuav raug hu mus ntxiv. Thaum kuaj nrog ib lub tshuab multimeter, ib qho ntawm cov kev xeem coj tau txuas nrog cov hlau casing los yog cov khoom siv casing ntawm lub hwj huam mov chav tsev, thiab lwm yam kev xeem txhuas yog txuas nrog rau hauv av, thiab muaj qhov voltage ntawm lawv. Kev nyeem ntawv ntawm multimeter qhia tau hais tias qhov kev xa tawm tam sim no ntawm ib qho ntawm peb lub ntsiab lus ntawm kev thauj khoom, qhov sib txuas nruab nrab, thiab cov khoom siv hluav taws xob yog qhov hnyav.
Ntawm lawv, cov txiaj ntsig ntawm kev ntsuas qhov xau yog qhov zoo tshaj plaws. Lub sijhawm no, nrhiav qhov chaw hauv av zoo ntawm qhov chaw kuaj pom, xws li cov kav dej zoo, cov av ntub dej thiab lwm cov ntsiab lus hauv av zoo. Tom qab ntawd txuas ib qho ntawm cov kev xeem coj ntawm multimeter mus rau lub plhaub ntawm lub cev them nyiaj kom kuaj pom, thiab lwm qhov kev sim ua rau qhov chaw xaiv hauv av. Nyob rau hauv txoj kev no, cov nyhuv leakage ntawm kev tshawb pom yog pom tseeb dua.
