Taw qhia rau Hom Kev Ntsuas Hluav Taws Xob nrog Multimeters
Transformer hom
Txoj kev siv hluav taws xob no feem ntau yog siv rau hauv cov khoom siv xws li xov tooj cua, cov kaw lus, hais lus, TV dub thiab dawb, thiab cov chaw taws teeb tswj xim xim thaum ntxov.
Lub hwj chim ntsaws yog txuas ncaj qha mus rau lub hwj chim transformer los yog standby transformer, thiab ib txhia yuav ntxiv ib lub hwj chim hloov nyob rau hauv nruab nrab.
Thaum ntsuas, qhib lub hwj chim hloov thiab siv lub multimeter los ntsuas ob tus pins ntawm lub hwj chim ntsaws. Lub sijhawm no, thawj kauj ruam ntawm transformer hauv lub tshuab yog ntsuas, thiab tus nqi tsis kam yog feem ntau ntawm ob peb puas mus rau ob txhiab ohms.
Switching fais fab mov hom
Hom khoom siv hluav taws xob no yog tam sim no feem ntau. Ntau lub xov tooj ntawm tes chargers, lub hwj chim adapters, thiab feem ntau LED teeb pom kev zoo yog rau hom no
Thaum ntsuas, Rx 1K lossis Rx 10K ntau yam ntawm tus pointer hom multimeter tuaj yeem xaiv. Thaum pib, yuav muaj tus nqi tiv thaiv me me, thiab tom qab ntawd maj mam nce. Nws zoo ib yam li qhov xwm txheej ntawm kev ntsuas me me muaj peev xwm electrolytic capacitors.
Txawm li cas los xij, qhov ntsuas no tsuas yog txwv rau pointer meters. Vim tias qhov tso zis hluav taws xob tsawg ntawm cov ntsuas hluav taws xob feem ntau, nws nyuaj rau kev tawg los ntawm qhov chaw txiav tawm ntawm tus choj rectifier, yog li nws muaj peev xwm ntsuas qhov ntsuas tsis tau.
Cov khoom siv hluav taws xob yooj yim
Cov khoom siv hluav taws xob cua sov feem ntau muaj xws li hluav taws xob cua sov, hluav taws xob kettles, thiab mov cookers. Lawv feem ntau siv cov cuab yeej tswj qhov kub thiab txias los tswj cov hluav taws xob cua sov hlau rau cua sov. Raws li peb feem ntau ntsuas nyob rau hauv chav tsev kub, qhov kub thiab txias hloov pauv yuav nyob rau hauv lub xeev, yog li qhov ntsuas tsis kam yog hluav taws xob cua sov hlau tsis kam.
Tus nqi tsis kam ntawm hom hluav taws xob cua sov hlau no feem ntau yog qis dua 100 Ω. Lo lus "yooj yim" nyob rau hauv lub subheading feem ntau yog hais txog mov cookers. Vim hais tias cov tswj Circuit Court ntawm ib co multifunctional mov cookers yuav tsum tau powered nyob rau hauv thiaj li yuav ua hauj lwm, txawm yog ntsuas ncaj qha nrog ib tug multimeter, tus nqi kuj yuav tsis ntsuas.
Resistance capacitance voltage txo hom
Hom kev tiv thaiv kev tiv thaiv hluav taws xob txo qis feem ntau yog siv hauv cov khoom siv hluav taws xob qis qis, xws li LED npuas teeb, teeb nyem me me, lossis cov khoom siv sab hauv rau shavers.
Vim lub peev xwm me me ntawm lub capacitor, nws yog qhov nyuaj rau kev ntsuas nrog multimeter. Tab sis yuav muaj kev tawm tsam ntawm ob peb puas K mus rau 1M Ω ntawm lub capacitor, yog li qhov ntsuas tsis kam yuav yog tus nqi ntawm qhov kev tiv thaiv ntawm qhov kev tiv thaiv no thiab kev thauj khoom. Nws tus nqi yuav yog me ntsis ntau dua qhov kev tawm tsam.
Rau kev ntsuas ntawm plaub qhov xwm txheej saum toj no, thawj thiab thib peb tuaj yeem ntsuas tau siv lub ntsuas ntsuas ntsuas lossis ntsuas digital, thaum lub thib ob thiab plaub yuav tsum ntsuas siv lub ntsuas ntsuas ntsuas.
Vim muaj kev sib txawv ntawm cov khoom siv hluav taws xob niaj hnub no, nws yog ib qho nyuaj rau kev txiav txim siab qhov zoo ntawm cov khoom siv hluav taws xob nkaus xwb los ntawm kev ntsuas lub taub hau fais fab. Tab sis feem ntau, cov txiaj ntsig kev ntsuas tuaj yeem ua lub hauv paus rau seb cov khoom siv hluav taws xob kuaj puas tuaj yeem siv rau kev sim ua haujlwm, uas tuaj yeem txo qis kev sib tsoo tshwm sim los ntawm kev siv fais fab tuag.
