Yuav ua li cas ntsuas qhov tam sim no ntawm kev them nyiaj tam sim no nrog multimeter
Thaum siv multimeter los ntsuas AC lossis DC tam sim no, koj yuav tsum teeb tsa qhov tam sim no ntawm multimeter mus rau AC lossis DC ntau yam, thiab ntsuas hauv kab hauv kab.
Rau ib qho analog multimeter, nws cov hlau kuaj liab yuav tsum tau txuas nrog cov txiaj ntsig zoo ntawm lub charger, thiab cov hlau lead dub yuav tsum tau txuas nrog cov khoom siv hluav taws xob raug them. Yog tias lub tshuab hluav taws xob digital siv los ntsuas qhov tam sim no hauv cov kab them nyiaj, nws cov kev sim liab thiab cov kev sim dub tseem tuaj yeem ntsuas tus nqi ntawm AC lossis DC tam sim no hauv kab txawm tias lawv txuas rov qab. Nws tsuas yog hais tias muaj ib tug -(- tsis zoo nyob rau hauv pem hauv ntej ntawm lub digital multimeter zaub. Number).
Thaum ntsuas me me AC lossis DC them tam sim no, koj tuaj yeem teeb tsa qhov tam sim no ntawm multimeter mus rau 500mA ntau. Yog tias koj xav ntsuas qhov them tam sim no tshaj 500mA, koj yuav tsum teeb tsa analog multimeter lossis digital multimeter rau 5A ntau ntawm analog multimeter (MF47 multimeter feem ntau tsuas muaj 5A DC tam sim no ntau yam tshwj tsis yog rau ob peb qauv uas muaj 10A. ntau), thiab Cov multimeter muaj AC lossis DC tam sim no ntau ntawm 10A lossis 20A.
Vim tias cov multimeter digital kuv feem ntau siv hloov pauv hloov pauv, Kuv tsuas tuaj yeem siv nws. Lwm cov digital multimeters tsuas yog yuav tsum tau teeb tsa lub iav kom taw tes rau 20A. Lub sijhawm no, ntxig cov hlau kuaj liab rau hauv 10 txoj haujlwm, thiab cov hlau kuaj dub tseem nyob hauv qhov qub COM jack.
Kuv tsis paub yog tias lub charger tus neeg nug hais txog yog lub xov tooj txawb charger lossis lub roj teeb tsheb charger. Tab sis tsis muaj teeb meem dab tsi ntawm lub charger nws yog, yog tias koj xav ntsuas qhov DC them tam sim no hauv kab, koj yuav tsum txiav tawm ib qho ntawm cov xov hlau them nyiaj (los yog txiav tawm ib qho ntawm cov xov hlau them rau lwm qhov ntawm lub ntsaws ntsaws, thiab txuas lub xov tooj ntawm tes. tus cwj mem liab ntawm lub multimeter, Cov kev xeem dub tau txuas nrog hauv koob thiab nyob hauv Circuit Court). Nyob rau lub sijhawm no, ntxig cov khoom siv hluav taws xob ntawm lub charger rau hauv 220V lub zog hluav taws xob thiab saib xyuas qhov tseeb them tam sim no ntawm lub charger thiab cov nqi them.
Yog tias nws yog lub xov tooj ntawm tes charger, koj yuav tsum tau khawb ib lub xov tooj them thiab ntsuas ob lub DC tam sim no qhov kev sojntsuam ntawm lub multimeter hauv kab.
Teem lub multimeter mus rau qhov tam sim no ntau yam, thiab xaiv qhov siab ntau ua ntej thiab tom qab ntawd qhov qis qis, thiab txuas nws hauv cov kab mus rau cov kab hluav taws xob uas yuav tsum tau ntsuas.
Dab tsi yuav tsum tau muab sau tseg ntawm no yog tias cov roj teeb feem ntau siv ib qho kev them nqi hluav taws xob tas li rau kev them nyiaj ceev. Txij li thaum lub them hluav taws xob tseem tsis hloov pauv thiab cov ntsiab lus ntawm ob qho kawg ntawm lub roj teeb kuj tsawg, qhov them tam sim no yuav loj heev thaum pib. Raws li qhov hluav taws xob ntawm ob qho kawg ntawm lub roj teeb nce, cov nqi them tam sim no yuav maj mam txo, yog li cov nqi them tam sim no ntsuas nyob rau lub sijhawm them nqi sib txawv.
Muaj qhov sib txawv loj ntawm lithium roj teeb them thiab cia roj teeb them. Txhawm rau tiv thaiv kev ua haujlwm siab tshaj plaws ntawm cov roj teeb lithium thiab tiv thaiv lub roj teeb lub neej, nws feem ntau tuaj yeem muab faib ua plaub theem: precharging, ceev them, them nyiaj rau sab saum toj, thiab kev them nyiaj qis. Yog li ntawd, qhov them tam sim no ntawm txhua theem kuj yuav txawv.
Muaj clamp multimeters thiab zoo tib yam multimeters. Hom clamp yog yooj yim. Kho lub 'meter' mus rau qhov chaw tam sim no thiab muab ib lub xaim nyob rau hauv kev sim rau hauv lub nplhaib clamp los nyeem cov ntaub ntawv. Ordinary multimeters yuav tsum tau txuas nrog nyob rau hauv series mus rau lub Circuit Court. Them mloog mus rau qhov ntau ntawm lub 'meter'. , ceev faj kub hnyiab. Qhov tam sim no uas lub ntsuas ntsuas ntsuas tau yuav tsis loj heev, yog li nws tsis haum rau ntsuas qhov ntsuas hluav taws xob tam sim no.
Tsuas yog siv lub multimeter los txuas lub charger. Rau lub xov tooj ntawm tes them, xaiv DC2A rau kev them nyiaj sai thiab DC500mA rau kev them qeeb. Los yog yuav cov lus nug tshwj xeeb rau kev them nyiaj ntawm lub xov tooj ntawm tes, uas tuaj yeem kuaj xyuas qhov them nqi hluav taws xob thiab roj teeb tib lub sijhawm. Nws muaj dual LED zaub, tus nqi yog hais txog 25 yuan, thiab cov tswv yim thiab cov zis yog USI3 interfaces.
Tsis tas li ntawd, koj tuaj yeem ntxiv 1 ohm resistor nyob rau hauv series rau lub voj, thiab tom qab ntawd ncaj qha ntsuas qhov voltage hla lub resistor. Tus nqi hluav taws xob yog tus nqi tam sim no. Txij li thaum qhov ntxig ntawm cov resistor txo qhov tam sim no tag nrho, qhov tseeb tam sim no yuav loj dua me ntsis ntawm qhov ntsuas tus nqi. (蠠=v/R, thaum R=1,
蠠=v).
Teem lub multimeter rau qhov sib thooj tam sim no. Yog tias koj tsis paub, sim siv qhov ntau tshaj plaws. Feem ntau, qhov siab tshaj plaws ntawm multimeter yog 10A lossis 20A. Koj yuav tsum tau tshem tawm cov xov hlau liab thiab ntsaws rau hauv lub qhov (socket) tshwj xeeb. Nrog lub roj teeb txuas mus rau ib qho kawg ntawm lub charger, txuas ib qho ntawm ob qhov kev xeem coj ntawm lub multimeter mus rau lwm qhov kawg ntawm lub charger, thiab lwm qhov mus rau lwm qhov kawg ntawm lub roj teeb. Nws tsis muaj teeb meem yog tias nws yog digital multimeter. Yog hais tias nws yog ib tug analog multimeter, koj yuav tsum xyuam xim rau lub polarity. Cov hlau kuaj liab yuav tsum tau txuas nrog tus ncej zoo ntawm lub charger lossis tus ncej tsis zoo ntawm lub roj teeb, thiab cov hlau kuaj dub yuav tsum tau txuas nrog tus ncej tsis zoo ntawm lub charger lossis tus ncej zoo ntawm lub roj teeb. Nws nyob ntawm qhov kawg koj txoj hlua hauv.
Cov zis tam sim no ntawm 12V charger dav dav yuav tsis tshaj 8A, thiab cov zis tam sim no ntawm ib qho zoo dua yuav loj heev. Lub multimeter lead hlau yog nyias dhau thiab tsis haum rau kev tshawb pom ntawm lub charger tso zis tam sim no. Nws yog qhov zoo tshaj los siv cov cuab yeej ntsuas tsis sib cuag.
Muaj cov theem tam sim no ntawm multimeter (ob theem, mA thiab A). Raws li cov lus qhia, ntxig cov xim liab thiab cov xim dub coj mus kuaj rau hauv lub qhov, teeb lub multimeter mus rau qhov sib luag A ntau, thiab tom qab ntawd txuas cov xim liab thiab xim dub coj mus rau hauv cov voj voog tam sim no los ntsuas.
