Hauv qhov xwm txheej dab tsi tsis tuaj yeem siv multimeter lossis tsis pom zoo?
Multimeter yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws rau cov neeg siv hluav taws xob. Vim tias nws yooj yim thiab siv tau, nws tuaj yeem hais tias txhua tus kws hluav taws xob muaj tsawg kawg yog ib qho ntawm nws txhais tes. Nws muaj tus lej loj. Nws tuaj yeem ntsuas qhov txuas ntxiv, qhov voltage, tam sim no, thiab txawm tias qee yam khoom siv hluav taws xob. Nws zoo li yog omnipotent. Lub peev xwm tshwj xeeb yog muaj zog, uas kuj yog lub hauv paus ntawm lub npe ntawm multimeter.
Peb feem ntau hais tias multimeter tuaj yeem ua qhov no lossis qhov ntawd, thiab peb ib txwm khaws nws nrog peb txhua zaus peb kho nws. Tab sis peb puas tau xav tias muaj xwm txheej thaum lub tshuab hluav taws xob siv tsis tau lossis siv tsis tau?
Niaj hnub no, cia peb tham txog qhov shortcomings ntawm multimeters. Thawj yog tam sim no. Multimeters tuaj yeem ntsuas tam sim no. Txawm li cas los xij, thaum ntsuas tam sim no, lawv yuav tsum tau txuas nrog hauv series hauv Circuit Court, txwv tsis pub lawv siv tsis tau. Feem ntau hais lus, koj xav txuas lub multimeter hauv series hauv Circuit Court los ntsuas. , nws tsis zoo heev thaum tam sim no loj. Ntawm qhov tod tes, tej zaum lub Circuit Court yuav tsum tau disassembled thiab txuas nyob rau hauv series. Yog li ntawd, lub multimeter tsis yog feem ntau siv thiab tsis siv heev thaum ntsuas tam sim no!
Qhov thib ob, nws yog los ntsuas qhov kev tiv thaiv hauv av thiab kev tiv thaiv kev tiv thaiv ntawm lub cev muaj zog cable. Vim hais tias lub zog siv los ntawm multimeter yog lub roj teeb, qhov hluav taws xob tsawg, thiab qhov kev tiv thaiv ntawm cov rwb thaiv tsev tiv thaiv ntsuas rau hauv av, cables thiab motors kuj loj, thiab nws yog ib qho nyuaj rau kev ntsuas nws nrog multimeter nyob rau hauv ib txwm muaj xwm txheej. Txawm hais tias qhov ntsuas qhov ua tau zoo, qhov yuam kev feem ntau loj, lossis txawm tias tus nqi tsis raug, uas tsis muaj nqi siv tiag tiag thiab qee zaum yuam kev. Yog li ntawd, nws tsis pom zoo kom siv lub multimeter hauv qhov no.
Lwm qhov xwm txheej yog tias tsis tuaj yeem siv multimeter, uas yog lub peev xwm roj teeb. Cov neeg feem ntau hais tias kuv lub tsheb roj teeb cia li tau them thiab tsis muaj zog tom qab tsav tsheb ib ntus. Puas yog lub roj teeb tawg? Qhov no hu ua phem roj teeb yeej txhais tau hais tias lub roj teeb muaj peev xwm txo. Kev siv ntau qhov chaw tsis tuaj yeem siv rau hom teeb meem no!
