Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov tsis kam thiab lub suab nrov ntawm lub tshuab multimeter thaum ntsuas qhov txuas ntxiv
Qhov kev tiv thaiv ntau yam ntawm multimeter tuaj yeem ntsuas qhov loj me ntawm kev tiv thaiv hluav taws xob, thiab peb tuaj yeem txheeb xyuas thiab txiav txim siab seb lub Circuit Court puas zoo li qub lossis muaj qhov ua txhaum raws li qhov loj me me.
Lub buzzing iav tsuas tuaj yeem txiav txim siab seb tus nqi tiv thaiv ntawm lub voj voog loj lossis me me (feem ntau nyob ib puag ncig 30-50 Ω raws li qhov sib faib, thiab tej zaum yuav muaj qee qhov sib txawv ntawm ntau qhov sib txawv).
Piv txwv tias qhov tseem ceeb ntawm kev tiv thaiv tus nqi rau lub multimeter kom emit ib tug beep yog 50 Ω, lub beep yuav tsuas yog suab thaum tus nqi ntawm lub Circuit Court los yog load yog tsawg tshaj li 50 Ω, thiab qhov qis kuj, lub suab nrov yuav nrov. Tab sis thaum tus nqi tsis kam ntawm Circuit Court lossis load ntau dua 50 Ω, lub beep iav yuav tsis suab. Yog li thaum cov kab tsis kam yog siab dua 50 Ω lossis ∞, peb tsis tuaj yeem paub qhov txawv ntawm nws siv lub beep iav.
Ib-theem lub cev muaj zog kev txiav txim zoo
Los ntawm cov lus nug, peb paub tias lub cev muaj zog muaj tag nrho ntawm 4 cov xov hlau, yog li peb tuaj yeem xav tias lub cev muaj zog yuav tsum yog lub cev muaj zog ib zaug (cov hom tshwj xeeb ntawm ib theem motors yuav tsum pom cov khoom tiag tiag los txiav txim siab).
Ib lub cev muaj zog muaj ob lub coil windings, ib qho yog pib winding thiab lwm qhov yog kev khiav hauj lwm winding. Vim yog lub coil thicker ntawm kev khiav hauj lwm winding thiab lub thinner kauj ntawm lub pib winding, tus nqi tsis kam ntawm qhov pib winding yog siab dua qhov kev khiav hauj lwm winding. Tus nqi tshwj xeeb kuj muaj feem xyuam rau lub cev muaj zog qauv thiab lub zog, xws li ntau tshaj kaum ohms mus rau ib lossis ob puas ohms. (Qhov siab dua lub cev muaj zog, qhov ua haujlwm qis dua; lub zog qis dua, qhov ua haujlwm ntau dua)
Yog hais tias lub zog ntawm lub cev muaj zog me me, nws cov nqi kuj yuav siab heev. Yog tias tus nqi tiv thaiv ntau dua 50 Ω, qhov tshwm sim peb ntsuas siv lub buzzer iav tsis muaj suab nrov. Ib yam li ntawd, yog hais tias lub cev muaj zog winding yog burnt tawm, ces peb yuav tsis ua suab nrov siv lub buzzer iav.
Yog hais tias lub cev muaj zog muaj zog, nws cov nqi kuj yuav tsawg heev. Yog tias tus nqi tiv thaiv tsawg dua 50 Ω, qhov tshwm sim peb ntsuas nrog lub suab nrov beep yog lub suab nrov. Ib yam li ntawd, yog hais tias ib tug luv luv Circuit Court tshwm sim nyob rau hauv nruab nrab ntawm lub motor winding, qhov tshwm sim peb ntsuas siv lub beep iav kuj qhia tau hais tias ib tug beep suab.
Yog li, rau qhov xwm txheej koj tau hais, yeej tsis muaj txoj hauv kev los txiav txim seb lub cev muaj zog puas zoo lossis phem. Txhawm rau txiav txim siab qhov zoo ntawm lub cev muaj zog, nws yog qhov yuav tsum tau soj ntsuam nws raws li kev sib xyaw ntawm lub cev muaj zog thiab lub zog.
Rau cov kws tshaj lij hluav taws xob uas nyuam qhuav tau ntsib nrog lub tshuab hluav taws xob, kuv xav tias thaum siv lub tshuab hluav taws xob los ntsuas cov khoom siv hluav taws xob lossis cov khoom thauj, sim siv qhov kev tiv thaiv ntau yam tsis yog lub suab nrov. Qhov no yuav pab tau heev rau kho thiab mastering lub multimeter. Tsuas yog tom qab ua tiav daim ntawv thov kev ntsuas kev tiv thaiv nrog lub multimeter txawj ntse, koj tuaj yeem siv lub beep iav los txhim kho kev ceev ceev.
