Taw qhia rau hom kev sib tw ntawm lub zog plugs ntsuas los ntawm multimeter
Ib transformer hom
Lub zog hluav taws xob no feem ntau yog siv hauv cov khoom siv hluav taws xob xws li cov tshuab hluav taws xob, cov kws sau ntawv, cov xov tooj, cov TV dub thiab dawb, thiab cov thaum ntxov-tswj TV.
Lub zog ntsaws tau ncaj qha rau lub zog hloov hluav taws xob lossis cov hloov chaw nres tsheb, thiab qee tus tuaj yeem ntxiv lub zog hluav taws xob hauv nruab nrab.
Thaum ntsuas, tig rau lub hwj chim hloov thiab siv ntau qhov kev ntsuas ntsuas ob pins ntawm lub hwj chim ntsaws. Nyob rau lub sijhawm no, tus thawj kauj ntawm cov transformer sab hauv lub tshuab yog ntsuas, thiab cov nqi tsis kam muaj feem ntau ntawm ob peb txhiab ohms.
II Hloov Chaw Fais Fab Khoom Hom
Cov cuab yeej hluav taws xob no yog tam sim no feem ntau. Ntau lub xov tooj txawb chaw siv, hluav taws xob hloov kho, thiab feem ntau LED teeb pom kev zoo consttures rau hom no
Thaum ntsuas kev ntsuas, RX 1K lossis R × 10K ntau ntawm tus taw tes motiver muaj peev xwm raug xaiv. Thaum pib, qhov tsis kam yuav qhia ib qho nqi me me thiab maj mam nce. Nws zoo ib yam li cov xwm txheej ntawm kev ntsuas me me muaj peev xwm electrolytic capacitors.
Tab sis qhov ntsuas no tsuas yog txwv rau tus taw qhia meters. Vim tias cov zis qis voltage ntawm cov digital meters, nws yog qhov nyuaj rau kev ua txhaum ntawm thaj chaw txiav tawm, yog li nws yog tau tias tus nqi tiv thaiv tsis tuaj yeem ntsuas.
III Yooj Yim Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob
Cov khoom siv hluav taws xob cua sov suav nrog cov cua kub hluav taws xob, cov hlau kettles hluav taws xob, thiab cov nplej nplej. Lawv feem ntau siv cov neeg kho tshuab ntsuas kub kom tswj cov xov cua kub rau cua sov. Txij li thaum peb feem ntau ntsuas ntawm chav sov, thaum lub chaw tswj kub hloov tau muab rau, ntsuas qhov kev tawm tsam yog qhov tsis kam ntawm cov cua sov hlau.
Cov kev tawm tsam ntawm hom hluav taws xob cua sov hlau feem ntau feem ntau yog qis dua 100 ω. Lo lus 'yooj yim' hauv subheading tsuas yog hais txog hluav taws xob mov nplej. Vim tias kev tswj hwm hluav taws ntawm qee cov multifunctional mov noj mov yuav tsum tau siv rau kev ua haujlwm, siv ntau yam tsis kam ua rau ntsuas nws yuav tsis muaj peev xwm ntsuas nws.
4 Tsis kam lees nthuav dav voltage txo hom
Resistive caperitive txo hom feem ntau yog siv hauv cov khoom siv hluav taws xob tsawg, cov teeb liab teeb, lossis cov tub rog lub chais sab hauv.
Vim muaj lub peev xwm me me ntawm capacitors, nws nyuaj rau kev ntsuas nrog tus multimeter. Tab sis yuav muaj kev tawm tsam tsis kam ntawm ntau pua k txog 1m ω ntawm lub capacitor, yog li ntsuas kev tawm tsam yuav yog cov kev ntsuas tsis kam ntawm qhov tsis kam thiab lub nra. Nws tus nqi yuav yog ib nyuag loj dua li kev tawm tsam tsis kam.
Rau qhov ntsuas ntawm cov plaub xwm saum toj no, pointer lossis digital meter tuaj yeem siv rau thawj thiab thib peb, thaum lub sijhawm taw me me yuav tsum tau siv rau qhov thib ob thiab thib plaub.
Vim yog cov kev tsim muaj ntau yam hluav taws xob cov khoom siv tam sim no, nws yog qhov nyuaj rau kev txiav txim siab qhov zoo ntawm cov vaj tse hluav taws xob feem ntau yog ntsuas lub hwj chim ntsaws. Tab sis feem ntau, qhov ntsuas tau tuaj yeem ua raws li kev sim hluav taws xob tuaj yeem siv rau kev ua haujlwm, uas tuaj yeem txo cov xwm txheej tshwm sim los ntawm lub zog.
