Thaum koj tab tom cuam tshuam nrog cov xov hluav taws xob, nws yog ib qho tseem ceeb kom paub tias cov xov hlau twg yog qhov zoo thiab qhov twg yog qhov tsis zoo. Txawm hais tias qee lub xov tooj tau cim meej nrog rau ntxiv (zoo) thiab rho tawm (tsis zoo) cov cim, lwm tus tsis yog. Rau cov xov hlau tsis cim, koj tuaj yeem xub txheeb xyuas qhov sib txawv los ntawm kev tshuaj xyuas cov yam ntxwv ntawm lub cev, xws li xim lossis kev ntxhib los mos. Yog tias koj tseem tsis paub tseeb, xyuas lub cable nrog lub digital multimeter. Tom qab ntawd, qhib lub zog!

Kauj Ruam 4. Nco ntsoov tias tooj liab tooj liab hauv tus hais lus feem ntau yog them tus nqi zoo

Hauv cov qauv siv hluav taws xob siv rau cov cuab yeej xws li lub suab nrov thiab lub tshuab ua kom nrov nrov, cov xim xim daj yog cov xaim tsis zoo thiab cov xim tooj liab yog cov xaim zoo. Cov xov hlau no feem ntau tau sib dhos ua ke nyob rau hauv cov ntaub thaiv uas ua rau nws yooj yim los txiav txim siab lawv cov kev sib txawv sai.

Hauv Cov Ntaub Ntawv Ntawm Cov Xim Cable Sib Txawv

Yog tias cov xov hlau dub thiab liab, dub yog ib qho xaim tsis zoo, qhov chaw liab yog ib txoj xov zoo.

Yog tias ob lub xov hlau dub, tab sis ib qho ntawm cov hlua muaj kab dawb, nws txhais tau tias dawb kab txaij hlau tsis zoo, ib ntus xaim dub dub yog qhov zoo.

Kauj Ruam 5. Qhib phau ntawv qhia neeg siv kom paub qhov xaim tsis zoo ntawm lub tsheb

Txhua lub tsheb ua raws nws tus kheej cable xim coding system. Tsis muaj tus txheej txheem lossis txheej txheem thoob ntiaj teb. Yog li, nrhiav qhov tshwj xeeb kab hluav taws xob daim duab rau koj ua thiab qauv hauv phau ntawv siv.

Yog tias koj tsis muaj phau ntawv qhia siv tsheb, nrhiav hauv lub tsev qiv ntawv lossis hauv is taws nem. Lossis, tshuaj nrog kws kho tsheb ntawm koj lub khw kho lossis chaw muag khoom hauv koj cheeb tsam

Kauj Ruam 1. Teeb lub digital multimeter rau qhov ncaj qha teeb tsa tam sim no

Tig tus xaiv qhov hloov pauv - uas yog, lub pob qhov rooj loj nyob nruab nrab ntawm lub multimeter - mus rau lub cim uas zoo li tus loj "V" nrog txoj kab ncaj nraim saum nws. Nov yog qhov ntsuas hluav taws xob ncaj qha tam sim no (DC) teeb tsa ntawm lub ntsuas hluav taws xob.

Tsis txhob siv analog multimeter los tshuaj xyuas polarity. Txuas cov hlau lead tsis raug (sojntsuam lossis sojntsuam) mus rau cov xovtooj tsis raug tuaj yeem ua rau lub analog multimeter puas tsuaj

Kauj Ruam 2. Txuas 1 tus txhuas rau txhua lub xaim txuas nws mus rau lub multimeter

Nyob rau theem no, nws tsis muaj teeb meem uas ua rau cov xaim txuas nrog. Kaw tus me me tus kauv ntawm tus liab coj mus rau qhov kawg ntawm ib txoj xov hlau, thiab ib tus dub mus rau lwm qhov kawg.

Txheeb xyuas tias cov hlau lead tau ntsaws rau hauv qhov chaw nres nkoj nyob rau sab xub ntiag ntawm lub multimeter sau tias "COM". Txuas cov hlau lead liab rau hauv qhov chaw nres nkoj sau nrog lub cim volt, uas yog "V"

Kauj Ruam 3. Saib ntawm lub vijtsam kom pom tias tus lej zoo lossis tsis zoo

Tom qab koj txuas cov kab ntawv mus rau kab uas koj xav tshuaj xyuas, kos tus lej ntawm cov duab multimeter. Qhov no yog qhov hluav taws xob cable, thiab tus lej tuaj yeem ua qhov zoo lossis tsis zoo.

  • Yog tias tsis muaj tus lej tshwm, ua ntej kuaj xyuas tias tus nab kuab txuas tau ruaj khov rau hauv kab.
  • Yog tias cov lej tseem tsis tshwm, hloov lub roj teeb multimeter thiab sim dua. Yog tias nws tseem tsis ua haujlwm, muaj feem yuav koj xav tau cov coj tshiab.

Kauj Ruam 4. Paub tias cov xaim txuas nrog cov hlau lead liab yog qhov zoo yog tias tus lej ntawm lub multimeter zaub zoo

Yog tias tus lej ntawm lub ntsuas hluav taws xob dhau los ua qhov zoo, piv txwv li 9, 2, nws txhais tau hais tias cov hlau lead tau txuas nrog kom raug. Ntawd yog, xaim pinched los ntawm cov hlau lead liab yog qhov zoo thiab xaim pinched nrog cov hlau dub yog qhov tsis zoo.

Yog tias tus lej multimeter tsis zoo, piv txwv li -9, 2, nws txhais tau tias cov hlau lead tau thim rov qab, txhais tau tias cov xaim txuas rau cov hlau lead liab tsis zoo

Kauj Ruam 5. Sib pauv cov hlau lead thiab muab tus liab liab tso rau lwm lub xov hlau kom txog thaum nws nyeem tus lej tsis zoo

Qhib cov hlau lead thiab txuas cov hlau lead liab rau cov xov tooj yav dhau los raug kaw rau cov hlau lead dub, thiab hloov pauv. Tom qab kev sib pauv, txheeb xyuas tias cov lej zoo los txheeb xyuas tias cov hlau lead tau txuas nrog cov xov hlau raug.

  • Piv txwv li, txheeb xyuas yog tias tus lej qub -9, 2 yog tam sim no 9, 2.
  • Yog tias tus lej tseem tsis zoo, nws txhais tau tias lub multimeter tsis raug. Nqa nws mus rau lub khw kho hluav taws xob kom kuaj xyuas lub fuse, lossis yuav ib lub multimeter tshiab.

Ceeb toom

  • Kev thim rov qab polarity hauv Circuit Court tuaj yeem ua rau lub zog puas tsuaj, txawm tias ua rau tawg.
  • Txuas lub xov tooj tsis raug -piv txwv li, siv lub xov tooj zoo them thaum nws yuav tsum tsis zoo - tseem tuaj yeem hlawv lub cable.
  • Tsis txhob siv analog multimeter yog tias koj tsis paub tseeb tias xaim twg zoo thiab xaim twg tsis zoo. Txuas qhov tsis ncaj ncees mus rau qhov ua tsis raug tuaj yeem ua rau lub multimeter puas tsuaj.
