Thaum twg los zam lossis tsis txhob siv Multimeter
Multimeter yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws rau cov neeg siv hluav taws xob, vim nws yooj yim thiab siv tau. Nws tuaj yeem hais tias txhua tus kws tshaj lij hluav taws xob muaj tsawg kawg yog ib txhais tes, nrog rau cov khoom muag loj heev. Nws tuaj yeem ntsuas kev tawm-tawm, voltage, tam sim no, thiab txawm tias qee yam khoom siv hluav taws xob. Nws zoo nkaus li yog omnipotent thiab muaj lub peev xwm tshwj xeeb muaj zog, uas kuj yog lub hauv paus ntawm lub npe multimeter.
Peb feem ntau hais tias ib tug multimeter yuav siv tau txoj kev no los yog li ntawd. Txhua zaus peb kho nws, lub multimeter yeej ib txwm nyob hauv peb txhais tes. Tab sis peb puas tau xav txog qhov xwm txheej uas lub multimeter siv tsis tau lossis siv tsis tau?
Niaj hnub no, peb tham txog qhov shortcomings ntawm multimeter. Ua ntej tshaj plaws, nws tuaj yeem ntsuas qhov tam sim no. Lub multimeter tuaj yeem ntsuas qhov tam sim no, tab sis nws yuav tsum tau txuas nrog hauv series hauv Circuit Court thaum ntsuas tam sim no, txwv tsis pub nws yuav siv tsis tau. Feem ntau, nws tsis muaj kev nyab xeeb heev los txuas lub multimeter hauv series hauv Circuit Court los ntsuas qhov siab tam sim no. Ntawm qhov tod tes, qee zaum lub Circuit Court yuav tsum tau muab tshem tawm thiab txuas nrog hauv koob. Yog li ntawd, multimeters tsis yog feem ntau siv los yog siv tau rau kev ntsuas tam sim no!
Qhov thib ob, nws yog ib qho tsim nyog los ntsuas qhov rwb thaiv tsev ntawm cov av tiv thaiv thiab cov kab hluav taws xob, vim tias lub zog siv hluav taws xob siv rau multimeters yog lub roj teeb uas tsis tshua muaj hluav taws xob. Txawm li cas los xij, ntsuas qhov rwb thaiv tsev tiv thaiv hauv av, cable motors, thiab lwm yam yog qhov siab. Feem ntau, nws yog ib qho nyuaj rau multimeters los ntsuas lawv cov kev ua tau zoo, thiab txawm tias lawv ntsuas, qhov yuam kev feem ntau loj, txawm tias qhov tsis raug, uas tsis muaj qhov siv tau zoo thiab qee zaum tuaj yeem ua yuam kev. Yog li ntawd, nws tsis pom zoo kom siv multimeter nyob rau hauv qhov teeb meem no.
Muaj lwm qhov xwm txheej uas tsis tuaj yeem siv multimeter, uas yog lub peev xwm roj teeb. Cov neeg feem ntau hais tias kuv lub scooter hluav taws xob nyuam qhuav tau them thiab siv roj teeb tawm tom qab tsav tsheb ib ntus. Puas yog vim lub roj teeb tawg? Qhov no hu ua roj teeb tsis ua haujlwm yog qhov tseeb vim qhov txo qis ntawm lub peev xwm roj teeb, thiab lub multimeter tsis tuaj yeem siv rau cov teeb meem zoo li no!
