Yuav ua li cas siv ib tug multimeter los xyuas luv luv Circuit Court, luv Circuit Court thiab to
Hnub no kuv yuav coj koj cov txuj ci tseem ceeb ntawm tus kws tshaj lij hluav taws xob, siv lub tshuab hluav taws xob los kuaj xyuas qhov luv luv Circuit Court, luv Circuit Court thiab to. Cov cuab yeej siv feem ntau siv rau cov tshuab hluav taws xob muaj xws li multimeters, clamp ammeters, megohmmeters, av resistance meters, hluav taws xob txuas hniav, thiab lwm yam. Multimeters muaj ntau txoj haujlwm, xws li ntsuas tam sim no, tsis kam, voltage, diodes, transistors, capacitance, inductance, kub, thiab lwm yam.
Xyuas luv luv Circuit Court nrog multimeter
Ib "luv luv luv" txhais tau hais tias ob qhov kawg ntawm lub zog hluav taws xob txuas ncaj qha los ntawm cov xaim. Siv ib lub multimeter los xyuas qhov luv luv Circuit Court txhais tau tias ntsuas qhov kev tiv thaiv los txiav txim seb lub Circuit Court puas txuas. Txij li qhov kev tiv thaiv ntau yam ntawm multimeter tsis tuaj yeem ntsuas thaum lub hwj chim qhib, qhov ntsuas kev tiv thaiv yuav tsum tau ua thaum lub hwj chim raug kaw.
Txoj Kev Txiav Txim Siab: Ua ntej tshaj tawm cov khoom siv hluav taws xob kom ntseeg tau tias tsis muaj hluav taws xob, thiab tom qab ntawd siv qhov kev tiv thaiv ntau yam ntawm multimeter los ntsuas ob qhov kawg ntawm cov khoom raug ntsuas. Hauv qhov xwm txheej ib txwm muaj, muaj qee qhov kev tiv thaiv tus nqi. Yog tias qhov ntsuas tsis kam yog xoom, nws txhais tau hais tias cov khoom raug ntsuas yog luv luv. Koj tuaj yeem siv hom buzzer lossis hom diode ntawm multimeter los ntsuas ob qhov kawg ntawm cov khoom nyob rau hauv kev sim thaum lub hwj chim tawm. Yog hais tias lub suab nrov nrov, nws txhais tau hais tias cov khoom nyob rau hauv kev sim muaj luv luv Circuit Court.
Lus Cim: Yog tias qhov ntsuas tsis kam muaj qee tus nqi tab sis tsawg heev, nws yuav muaj qhov luv luv tau tshwm sim, uas yog tshwm sim los ntawm kev tiv thaiv kev tiv thaiv. Peb qee zaum ntsib qhov xwm txheej no thaum ntsuas. Piv txwv li, yog tias koj nias tus cwj mem multimeter me ntsis nruj, qhov ntsuas tau yuav me dua; Yog tias koj so lub ntsuas ntsuas me ntsis, qhov ntsuas ntsuas yuav loj dua. Qhov no yog vim qhov kev xeem coj thiab cov xaim nyob rau hauv kev xeem tsis tau txuas nrog zoo, thiab kev tiv thaiv kev sib cuag ntawm qhov chaw sib txuas kuj raug ntsuas. Txhawm rau txo qhov ntsuas qhov yuam kev kom ntau li ntau tau thiab rov qab kho qhov tseeb ntawm cov txiaj ntsig. Yog li ntawd, qhov kev xeem coj thiab cov xaim ntawm cov khoom nyob rau hauv kev sim yuav tsum tau nruj nreem txuas thaum ntsuas; Yog hais tias cov hlau nyob rau hauv kev ntsuam xyuas yog hnyav heev corroded los yog oxidized, oxide txheej nyob rau saum npoo ntawm tus neeg xyuas pib yuav tsum tau scraped tawm. (Raws li cov xwm txheej ib txwm muaj, tooj liab yog xim daj daj, thiab tom qab oxidized, nws tig dub npub; tib yam muaj tseeb rau cov xov hlau txhuas)
Tshawb xyuas Circuit Court break nrog multimeter
Tom qab koj paub yuav ua li cas siv ib tug multimeter los kuaj rau luv luv Circuit Court, kev sim rau qhib Circuit Court yog yooj yim heev.
Txoj Kev Txiav Txim Siab: Ua ntej tshaj tawm cov khoom siv hluav taws xob los xyuas kom meej tias tsis muaj lub zog, thiab tom qab ntawd siv qhov sib txawv ntawm cov multimeter los ntsuas ob qhov kawg ntawm kab. Nyob rau hauv ib txwm muaj xwm txheej, qhov tsis kam yog xoom lossis muaj qee tus nqi tsis kam. Yog tias qhov ntsuas qhov ntsuas tsis muaj qhov kawg, nws txhais tau hais tias tsis muaj kev sib txuas ntawm ob qho kawg ntawm kab, uas yog, qhib Circuit Court tau tshwm sim. Koj tuaj yeem siv lub buzzer lossis diode teeb tsa ntawm multimeter los ntsuas ob qho kawg ntawm kab thaum lub hwj chim tawm. Yog tias muaj suab nrov, nws txhais tau hais tias txoj kab txuas nrog; ntawm qhov tsis sib xws, yog tias tsis muaj suab nrov, nws txhais tau hais tias kab hauv kev sim yuav luv luv.
Lus Cim: Qhov kev tiv thaiv ntawm ob qho kawg ntawm cov hlau yog xoom (lossis ze rau xoom) nyob rau hauv ib txwm muaj xwm txheej; cov khoom siv hluav taws xob muaj qee qhov kev tiv thaiv nyob rau hauv ib txwm muaj, tab sis qhov tshwj xeeb kuj nyob ntawm nws tus kheej. Yog li ntawd, txhawm rau txiav txim siab seb lub Circuit Court lossis cov khoom siv hluav taws xob qhib, nws yog qhov zoo tshaj plaws los siv lub resistor nrog ntau yam. Vim tias qhov kev tiv thaiv ntawm qee cov khoom siv hluav taws xob loj heev, xws li lub teeb txuag hluav taws xob, uas tsis tuaj yeem ntsuas nrog ntau yam me me.
Multimeter los ntsuas qhov to
Ua ntej ntawm tag nrho cov, peb yuav tsum xav txog ib lo lus nug: Dab tsi yog qhov txawv ntawm cov khoom xau thiab cov xwm txheej zoo li cas? Raws li ib txwm muaj, cov kab nruab nrab ntawm cov khoom siv hluav taws xob yog insulated thiab tsis muaj kev sib txuas nrog cov khoom siv plhaub. Thaum lub rwb thaiv tsev ntawm cov khoom siv hluav taws xob puas lawm, piv txwv li, cov hlau tsis huv lossis cov hlau nyob txuas nrog lub plhaub, ces tam sim no yuav ntws mus rau lub plhaub, ua rau lub plhaub hluav taws xob. Yog li ntawd, koj tuaj yeem txiav txim siab seb cov khoom siv hluav taws xob puas los ntawm kev ntsuas seb cov hlau tsis huv lossis cov hlau nyob txuas nrog lub plhaub.
Txoj Kev Txiav Txim Siab: Ua ntej tshaj tawm cov khoom siv hluav taws xob kom ntseeg tau tias tsis muaj hluav taws xob, teeb tsa lub iav mus rau qhov siab tshaj plaws ntawm cov iav tiv thaiv, thiab tom qab ntawd siv multimeter los ntsuas qhov tsis kam ntawm cov hlau nruab nrab (lossis nyob hlau) thiab lub plhaub ( los yog hauv av xaim txuas nrog lub plhaub). Nyob rau hauv ib txwm muaj xwm txheej, tus nqi kuj yuav tsum yog infinite. Yog hais tias ib qho kev tiv thaiv tus nqi raug ntsuas, nws txhais tau tias muaj to.
Faj seeb: Ib qho multimeter rau ntsuas qhov xau tsuas yog tsim nyog rau cov xwm txheej uas cov dej xau loj heev, xws li thaum cov hlau tsis huv lossis cov hlau nyob ze kov cov hlau casing. Cov dej xau los ntawm cov rwb thaiv tsev tsis txaus tsis tuaj yeem tshawb pom, xws li thaum cov hlau tawv tawv tab sis tseem muaj peev xwm tiv thaiv qee yam. Txij li thaum cov hlau sheath muaj ib qho kev rwb thaiv tsev lub zog, nws tsis yog-conductive ntawm tsawg voltage, tab sis to yuav tshwm sim thaum lub voltage siab. Yog tias koj xav ntsuas qhov tseeb seb qhov hluav taws xob lossis cov khoom siv puas, koj yuav tsum siv cov cuab yeej tshaj lij--- megger (megger).
