Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov tsis kam thiab qhov buzzer ntau yam ntawm multimeter thaum ntsuas qhov txuas ntxiv?
Qhov txawv ntawm lawv yog:
Qhov kev tiv thaiv ntau yam ntawm multimeter tuaj yeem ntsuas qhov tshwj xeeb tsis kam ntawm ib lub voj voog, thiab tom qab ntawd peb tuaj yeem txheeb xyuas thiab txiav txim siab seb lub Circuit Court puas zoo li qub lossis yog tias muaj qhov tsis raug raws li tus nqi tiv thaiv.
Lub buzzing hom tsuas tuaj yeem txiav txim siab seb qhov kev tiv thaiv ntawm Circuit Court yog siab lossis qis (feem ntau nyob ib ncig ntawm 30-50 Ω raws li qhov sib faib, nrog qee qhov sib txawv nyob ntawm qhov multimeter).
Piv txwv tias qhov tseem ceeb ntawm kev tiv thaiv tus nqi rau lub multimeter kom tawm suab beep yog 50 Ω, lub suab beep tsuas yog tshwm sim thaum qhov kev tiv thaiv ntawm Circuit Court lossis load tsawg dua 50 Ω, thiab qhov me dua qhov tsis kam, lub suab nrov ntau dua. Tab sis thaum qhov kev tiv thaiv ntawm Circuit Court lossis load ntau dua 50 Ω, buzzing hom yuav tsis suab. Yog li thaum qhov kev tiv thaiv ntawm Circuit Court yog ntau dua 50 Ω lossis ∞, peb tsis tuaj yeem paub qhov txawv ntawm nws siv hom buzzer.
Lub cev muaj zog ib zaug muaj ob lub coil windings, ib qho yog pib winding thiab lwm qhov yog khiav winding. Vim lub thicker khiav winding kauj thiab thinner pib winding kauj, tus nqi tsis kam ntawm qhov pib winding yog siab dua li ntawm kev khiav winding. Tus nqi tshwj xeeb kuj nyob ntawm tus qauv lub cev muaj zog thiab lub zog, xws li kaum tawm ohms mus rau ib lossis ob puas ohms. (Qhov loj dua lub cev muaj zog, qhov me dua qhov tsis kam; lub zog me dua, qhov loj dua qhov tsis kam)
Yog hais tias lub zog ntawm lub cev muaj zog tsawg heev, nws cov nqi kuj yuav siab heev. Yog tias tus nqi tiv thaiv ntau dua 50 Ω, qhov tshwm sim peb ntsuas siv hom buzzer yuav tsis suab. Ib yam li ntawd, yog tias lub cev muaj zog winding hlawv tawm, peb yuav tsis ua suab nrov txawm tias siv hom buzzer rau kev sim.
Yog hais tias lub cev muaj zog muaj zog, nws kuj yuav tsawg heev. Yog tias qhov kev tawm tsam tsawg dua 50 Ω, qhov tshwm sim peb ntsuas siv hom buzzer yog tias muaj 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 buzzer hom kuj yuav tsim ib tug buzzing suab.
Yog li, rau qhov xwm txheej koj tau hais, nws yog qhov tsis yooj yim sua kom txiav txim siab seb lub cev muaj zog 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 phooj ywg hluav taws xob uas nyuam qhuav pib siv lub multimeter, kuv xav tias thaum ntsuas circuits lossis loads nrog multimeter, sim siv hom kev tiv thaiv tsis yog hom buzzer. Qhov no yuav pab tau heev rau kho thiab mastering lub multimeter. Tsuas yog tom qab koj tau ua tiav daim ntawv thov siv multimeter los ntsuas kev tiv thaiv, koj tuaj yeem siv hom buzzer los txhim kho kev ceev ceev.
