Kev siv cov hlau nyob hauv cov hlau cim kev ua haujlwm ntawm tus motimeter?
Tus cwj mem cwj pwm zoo tib yam: Yav dhau los, thaum muaj hluav taws xob daws teeb meem, cwj mem zoo nkauj yog lawv cov cuab yeej tseem ceeb. Feem ntau cov neeg yeej paub yuav ua li cas paub qhov txawv ntawm cov xaim hlau nyob thiab cov hlau nruab nrab nrog tus cwj mem zoo tib yam. Tsuas yog siv tus cwj mem xeem los ntsuas cov xaim hlau nyob thiab cov hlau nruab nrab ncaj qha. Yog hais tias tus cwj mem ntsia teeb, nws yog cov hlau nyob; Yog tias nws tsis taws, nws yog lub hlau nruab nrab.
Digital kuaj cwj mem: Vim tias qhov tshwm sim ntawm cov digital kuaj cwj mem, tus cwj mem zoo tib yam li qub. Tus cwj mem digital kuaj cwj mem muaj ntau dua cov haujlwm. Piv txwv li, nws tuaj yeem tshawb xyuas rau cov xaim tawg tsis muaj lub zog, paub qhov txawv ntawm cov xaim hluav taws xob nruab nrab thiab txiav txim siab seb puas muaj lub roj teeb thiab txiav txim siab seb puas muaj cov xaim luv luv hauv cov hlau. Yog li, maj mam, tus cwj mem ib txwm muaj phased tawm. Txhawm rau paub qhov txawv ntawm cov hlau nyob thiab lub nruab nrab ntawm cov hlau nrog tus cwj mem digital nrog tus cwj mem thiab saib cov cwj mem ntawm digital. Yog tias qhov ntsuas siab tshaj plaws yog 220V, nws ua pov thawj ua cov hlau nyob. Yog tias qhov siab tshaj plaws pom yog 12v lossis 36V, nws ua pov thawj los ua ib tus neeg nruab nrab.
Inductive beatpoint kev sim cwj mem: Lub luag haujlwm tseem ceeb ntawm kev kuaj tus cwj mem Breakpoin Txhawm rau paub qhov txawv ntawm cov xaim hlau nyob thiab cov hlau nruab nrab nrog cov xaim hluav taws xob (ntsuas cov xaim xaim thiab cov xaim nruab nrab feem nrog nws. Thaum ntsuas cov xaim xaim nyob nrog tus cwj mem tawg, lub suab nws ua rau nrawm, thaum ntsuas qhov nruab nrab ntawm cov hlau nruab nrab, lub suab yog qeeb.
Txoj kev ntawm kev paub qhov txawv ntawm cov xaim hlau nyob thiab cov hlau nruab nrab nrog lub multimeter
Tus multimeter muaj ib qho hluav taws xob ntau npaum li cas, uas tuaj yeem siv los ntsuas qhov hluav taws xob ntawm txoj kev hloov tshiab. Thaum ntsuas qhov ntsuas hluav taws xob, tso cov kev xeem liab thiab dub ua rau cov xaim hlau nyob ntawm cov xaim thiab qhov chaw nruab nrab yuav raug tso tawm. Txawm li cas los xij, thaum ntsuas qhov ntsuas hluav taws xob, nws yog qhov yuav tsum tau teeb tsa ntau sib txuam rau ib qho uas tsim nyog. Piv txwv li, thaum ntsuas cov tsev neeg voltage ntawm 220V lossis 380v, pulcev, palultimeter yuav tsum tau teeb tsa rau qhov hluav taws xob ntau ntawm 700V.
Qhov hluav taws xob ntau ntawm cov puv hluav taws xob ntawm cov multimeter tsis tuaj yeem ntsuas qhov hluav taws xob tab sis kuj tseem paub qhov txawv ntawm cov hlau nyob ntawm cov xaim hluav taws xob thiab cov neeg nruab nrab tsis paub txog qhov no. Txhawm rau paub qhov txawv ntawm cov hlau nyob thiab cov hlau nruab nrab nrog cov ntsuas hluav taws xob ntau, thiab siv cov xim liab ua rau ntsuas cov xaim hluav taws xob thiab cov xaim nruab nrab feem. Saib xyuas tus lej ntawm pullimeter. Cov hlau nrog tus lej loj dua yog cov hlau nyob, thiab ib qho nrog tus lej me me yog qhov nruab nrab ntawm nruab nrab. Yog tias cov naj npawb tsis pom tseeb, koj tuaj yeem kho cov kab kom me dua, thiab tom qab ntawd cov lej yuav txawv.
