Yuav ua li cas siv ib tug multimeter los ntsuas qhov tsis xws luag nyob rau hauv ib txoj hlua hlua los yog cov khoom siv
Multimeter yog ib qho tseem ceeb ntsuas ntsuas rau cov neeg siv hluav taws xob, lub multimeter tuaj yeem ntsuas qhov voltage, ntsuas tam sim no, ntsuas qhov tsis kam thiab ntsuas lub peev xwm ntawm cov capacitors thiab ntau lwm yam khoom siv lub cev tuaj yeem ntsuas nrog nws. Yog li ntawd, multimeter plays lub luag haujlwm tseem ceeb hauv kev ntsuas kab thiab kho cov kab hluav taws xob. Yuav ua li cas siv lub multimeter los ntsuas cov kab lossis cov khoom ua txhaum cai.
Kev xau txhais li cas?
Kev xau yog vim tias cov txheej txheej rwb thaiv tsev ntawm cov xaim raug puas lawm thiab lub plhaub hluav taws xob ntawm cov khoom siv hluav taws xob ntawm qhov kev sib txuas ntawm kev sib raug zoo, uas ua rau cov tam sim no nyob rau hauv cov hlau "xov" tawm, xws li lub plhaub lub cev muaj zog thiab peb-theem hluav taws xob txhua theem. kev sib cuag tej zaum yuav ua rau to; tseem muaj lub plhaub ntawm cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob hauv cov hluav taws xob hluav taws xob ntawm cov hluav taws xob sib txuas vim qee qhov laj thawj. Kev sib txuas hluav taws xob, kom cov hlau casing ntawm cov khoom siv hauv tsev thiab cov hluav taws xob hluav taws xob ntawm ib qho kev sib txawv ntawm cov xwm txheej no kuj dhau los. Qhov tshwm sim ntawm kev xau yuav ua rau muaj kev phom sij loj heev, yooj yim heev rau kev ua haujlwm ntawm cov neeg ua haujlwm ntawm lub tshuab hluav taws xob sib tsoo, nyob rau hauv qhov chaw no peb feem ntau siv cov khoom tiv thaiv los tiv thaiv Circuit Court.
Multimeter nrog dab tsi iav los ntsuas qhov to ntawm hluav taws xob
Thaum qhov kev huam yuaj tshwm sim li cas los xyuas nws? Qhov no yog ntau tus phooj ywg txhawj xeeb txog qhov teeb meem, Kuv xav tham txog kuv qhov kev xav ntawm qhov teeb meem no, rau qhov teeb meem zoo li no peb thawj zaug xav txog yog siv cov multimeter los kuaj xyuas cov khoom siv hluav taws xob tsis yog qhov ua txhaum, kuv xav tias muaj. tsis muaj ntau tshaj li ob txoj hauv kev los ntes, ib qho yog siv txoj kev tiv thaiv; Lwm qhov yog txoj kev voltage.
1, tiv thaiv txoj kev los xyuas kom meej qhov txhaum
Txoj kev tiv thaiv txhawm rau txhawm rau txhawm rau txhawm rau ua ntej txiav tawm lub zog ntawm cov khoom siv hluav taws xob, peb tuaj yeem siv lub pointer multimeter RX10K iav yog tias cov iav digital multimeter tuaj yeem ua si ntawm 200M iav, nrog rau multimeter cwj mem tiv tauj nrog lub firewire (theem) ntawm lub Circuit Court, thiab tom qab ntawd siv lwm tus cwj mem rau kev sib cuag nrog cov hlau casing ntawm cov cuab yeej, nyob rau hauv ib txwm muaj xwm txheej, lub multimeter tus pointer yuav tsum qhia tus nqi ntawm kev tiv thaiv infinity, yog tias tus pointer muaj deflection, ces nws txhais tau hais tias cov khoom siv hluav taws xob tsis yog. leak. Yog tias rab koob muaj qhov deflection, nws txhais tau hais tias cov hlau casing ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm lub rwb thaiv tsev lub zog tsis txaus, yog li nws yog qhov xau ntawm hluav taws xob.
