Tam sim no koj muaj cov cuab yeej thiab cov cuab yeej uas yuav tsum tau ua, cia peb mus rau cov ncauj lus kom ntxaws cov kauj ruam ntawm kev sim LED Christmas teeb nrog multimeter.

Kauj ruam 1: Teeb lub Multimeter

Ua ntej pib cov txheej txheem kuaj, nws yog ib qho tseem ceeb kom paub meej tias lub multimeter raug teeb tsa kom raug. Nov yog yuav ua li cas:

1. Qhib lub multimeter thiab xaiv qhov kev tiv thaiv (Ω) teeb tsa. Feem ntau cov multimeters muaj lub xov tooj sib cais rau kev ntsuas sib txawv, yog li nrhiav qhov chaw tiv thaiv ntawm lub dial.

2. Teem qhov ntau yam rau tus nqi qis tshaj plaws. Qhov kev teeb tsa no yuav muab cov kev nyeem ntawv tseeb tshaj plaws thaum kuaj lub teeb LED.

3. Txiav txim siab seb koj lub multimeter puas muaj qhov ntsuas qhov txuas txuas ntxiv. Kev ntsuas txuas ntxiv pab txheeb xyuas cov kev tawg hauv Circuit Court. Yog tias koj lub multimeter muaj qhov no, hloov nws.

Kauj Ruam 2: Ntsuas cov teeb ci LED kom txuas ntxiv mus

Kev ntsuam xyuas txuas ntxiv tso cai rau koj txheeb xyuas txhua lub cev tawg lossis cuam tshuam hauv hluav taws xob hluav taws xob ntawm koj lub teeb Christmas LED. Nov yog yuav ua li cas mus ntxiv:

1. Tshem tawm cov teeb ci LED los ntawm txhua qhov chaw siv hluav taws xob kom ntseeg tau tias koj muaj kev nyab xeeb.

2. Coj ob txoj kev sojntsuam ntawm koj lub multimeter thiab kov ib qho txhuas mus rau cov hlau tooj liab ntawm ib kawg ntawm txoj hlua LED, thiab lwm qhov ua rau cov hlau ntawm qhov kawg. Yog tias qhov ntsuas qhov txuas txuas mus ntxiv, koj yuav tsum hnov ​​​​ib lub suab nrov lossis pom kev nyeem ntawv ze rau xoom tsis kam ntawm lub multimeter zaub. Qhov no qhia tias lub voj voog ua tiav thiab tsis muaj kev tawg.

3. Yog tias koj tsis hnov ​​​​ib lub suab nrov lossis qhov kev nyeem ntawv tsis txaus siab dhau lawm, txav mus rau qhov kev sojntsuam ua raws txoj hlua, kuaj xyuas ntawm ntau lub ntsiab lus, kom txog rau thaum koj pom qhov tawg qhov twg lub Circuit Court cuam tshuam. Qhov no tuaj yeem yog vim cov xaim puas lossis LED tsis raug.

Kauj Ruam 3: Txheeb xyuas qhov ua tau zoo ntawm qhov hluav taws xob

Thaum koj tau txiav txim siab qhov txuas ntxiv ntawm koj lub teeb Christmas LED, nws yog lub sijhawm los xyuas lawv qhov kev ua haujlwm voltage. Ua raws li cov kauj ruam no:

1. Tig koj lub multimeter dial rau qhov voltage (V) teeb. Yog tias nws muaj ntau qhov sib txawv, muab nws tso rau qhov chaw ze tshaj plaws rau qhov xav tau qhov hluav taws xob ntawm LED teeb. Piv txwv li, yog tias koj muaj ib txoj hlua ntawm lub teeb ntsuas rau 12 volts, xaiv 20-volt ntau yam.

2. ntsaws rau hauv lub teeb LED thiab xyuas kom meej tias lawv txuas nrog lub hwj chim.

3. Kov qhov zoo (liab) sojntsuam ua rau lub davhlau ya nyob twg zoo lossis xaim ntawm lub teeb LED. Tom qab ntawd, kov qhov tsis zoo (dub) sojntsuam ua rau lub davhlau ya nyob twg tsis zoo lossis xaim.

4. Nyeem qhov voltage tso tawm ntawm lub multimeter. Yog tias nws nyob hauv qhov xav tau (piv txwv li, 11V-13V rau 12V teeb), lub teeb ua haujlwm raug. Yog tias qhov kev nyeem ntawv voltage qis dua lossis siab dua li qhov xav tau, tej zaum yuav muaj teeb meem nrog lub hwj chim lossis lub teeb lawv tus kheej.

Kauj Ruam 4: Ntsuas qhov tsis kam

Kev ntsuas kev tiv thaiv tuaj yeem pab txheeb xyuas cov teeb meem nrog cov LEDs tshwj xeeb, xws li cov uas yuav ua yuam kev lossis hlawv tawm. Ntawm no yog yuav ua li cas ntsuas kev tiv thaiv:

1. Hloov lub dial ntawm koj lub multimeter mus rau qhov tsis kam (Ω) teeb tsa.

2. Cais cov LED koj xav sim los ntawm cov hlua seem. Nrhiav ob lub xov hlau txuas nrog LED koj xav ntsuas.

3. Kov ib qho kev sojntsuam multimeter ua rau txhua lub xov hlau txuas nrog LED. Qhov kev txiav txim tsis muaj teeb meem raws li lub multimeter yuav ntes qhov tsis kam tsis hais.

4. Txheeb xyuas qhov kev nyeem ntawv ntawm cov khoom siv multimeter. Yog tias qhov tsis kam yog ze rau xoom, LED yuav ua haujlwm kom raug. Txawm li cas los xij, yog tias kev nyeem ntawv tsis kawg lossis siab dua li qhov xav tau, LED yuav tsis zoo thiab yuav tsum tau hloov.

Kauj Ruam 5: Txheeb xyuas qhov teeb meem

Tom qab ua raws li cov kauj ruam dhau los, koj yuav tau ntsib qee yam teeb meem. Cia peb tham txog cov teeb meem uas yuav tshwm sim thiab lawv cov kev daws teeb meem:

1. Yog tias koj tsis tau hnov ​​​​ib lub suab nrov thaum kuaj kev txuas ntxiv lossis qhov kev nyeem ntawv siab dhau lawm, koj yuav muaj cov hlau tawg. Ua tib zoo tshuaj xyuas qhov chaw uas qhov tawg tau tshwm sim thiab, yog tias ua tau, kho cov xaim siv hluav taws xob daim kab xev lossis cov khoom siv.

2. Yog tias qhov kev nyeem ntawv voltage siab dua lossis qis dua li qhov xav tau, koj yuav muaj teeb meem ntawm lub hwj chim. Xyuas kom meej tias lub zog hluav taws xob sib phim qhov kev xav tau ntawm qhov hluav taws xob ntawm LED teeb thiab xav txog kev hloov lub zog hluav taws xob yog tias xav tau.

3. Yog hais tias ib tug neeg LED qhia infinite kuj los yog ib tug tsis tshua muaj siab tsis kam nyeem ntawv, nws yuav faulty los yog hlawv tawm. Hloov cov teeb meem LED feem ntau tuaj yeem daws qhov teeb meem no.

Hauv kev xaus, kev sim LED Christmas teeb nrog lub multimeter yog ib txoj hauv kev yooj yim uas tso cai rau koj txheeb xyuas thiab kho txhua yam teeb meem uas koj lub teeb yuav ntsib. Los ntawm ua raws li cov kauj ruam uas tau teev tseg saum toj no, koj tuaj yeem txaus siab rau lub caij so zoo nkauj thaum ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm koj lub teeb Christmas LED. Nco ntsoov ib txwm saib xyuas kev nyab xeeb thaum ua haujlwm nrog cov khoom siv hluav taws xob thiab siv ceev faj thaum cuam tshuam nrog cov xaim hluav taws xob lossis cov khoom siv hluav taws xob.
