Yuav ua li cas koj sim rau luv luv circuits thiab qhib circuits nrog ib tug multimeter?
Multimeter yog ib qho tseem ceeb "hardcore" cov cuab yeej rau cov neeg koom nrog hauv electronics, hluav taws xob engineering, thiab kev saib xyuas. Nws boasts haib zog thiab yuav siv tau los ntsuas AC voltage, DC voltage, AC tam sim no, DC tam sim no, tsis kam, capacitance, diodes, transistors, kub, thiab lwm yam. Piv txwv li, thaum peb sim thiab debug cov khoom, peb yuav tsum tau siv ib tug multimeter los pab nyob rau hauv kev txheeb xyuas cov teeb meem.
Thaum cov khoom lag luam ua haujlwm tsis zoo, kuv feem ntau yog thawj zaug siv lub voltmeter los ntsuas seb cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob puas zoo li qub, txhawm rau txiav txim siab seb lub zog hluav taws xob puas ua haujlwm zoo. Thaum qhov hluav taws xob tsis zoo, nws feem ntau qhia tias muaj luv luv Circuit Court lossis qhib Circuit Court.
Buzzer iav xeem rau luv luv Circuit Court thiab qhib Circuit Court
Digital multimeters feem ntau muaj qhov chaw buzzer. Thaum kuaj pom kev sib txuas, nws yuav tawm suab "BI", uas yog qhov yooj yim heev thiab tshem tawm qhov xav tau los saib xyuas cov multimeter tas li.
Thaum ntsuas ob txoj haujlwm uas yuav tsum tsis txhob sib txuas, yog tias lub suab "BI" raug tso tawm, nws qhia tau hais tias luv luv; thaum ntsuas ob txoj haujlwm uas yuav tsum tau txuas nrog, yog tias tsis muaj "BI" suab tawm, nws qhia tau hais tias qhib Circuit Court;
Yog tias koj lub multimeter tsis muaj qhov teeb tsa buzzer, koj tseem tuaj yeem siv qhov chaw tiv thaiv los txiav txim seb puas muaj qhov luv luv lossis qhib Circuit Court los ntawm kev ua raws li txoj kev ntsuas kev tiv thaiv. Yog tias qhov kev tiv thaiv qis heev, tsuas yog ob peb ohms, lossis txawm tias ob peb feem kaum ntawm ohm, nws qhia tau hais tias luv luv; Yog tias tsis muaj tus nqi tiv thaiv tuaj yeem ntsuas tau lossis tus nqi tiv thaiv siab heev, nws qhia tau hais tias qhib Circuit Court.
Kev ntsuas qhov dej
Cov hluav taws xob xau tau muab faib ua hluav taws xob muaj zog thiab hluav taws xob tsis muaj zog. Cov hluav taws xob muaj zog yog hais txog kev xau ntawm qhov siab -voltage alternating tam sim no (AC), uas tuaj yeem cuam tshuam cov neeg siv hluav taws xob lossis ua rau cov dej xau mus rau qhov chaw. Koj tuaj yeem siv multimeter teem rau AC hom los ntsuas seb puas muaj qee qhov AC voltage tam sim no. Lwm txoj hauv kev yog tshem tawm cov khoom siv hluav taws xob thiab siv qhov chaw tiv thaiv ntawm qhov siab tshaj plaws los ntsuas qhov kev tiv thaiv ntawm qhov xau thiab cov xaim nyob (L) lossis cov xaim nruab nrab (N). Yog tias tsis muaj qhov to, qhov kev tiv thaiv tus nqi yuav siab heev, sib npaug rau rwb thaiv tsev. Yog hais tias qhov kev tiv thaiv rau hauv av tsis siab txaus, thiab qhov ntsuas tsis kam yog nyob rau hauv ntau pua kilohms, ces tej zaum yuav muaj to.
Yog tias koj xav txheeb xyuas qhov xau me ntsis hauv qhov tsis muaj zog tam sim no, koj tuaj yeem siv qhov tam sim no ntau yam ntawm multimeter thiab txuas rau hauv series rau hauv Circuit Court los ntsuas seb qhov kev khiav hauj lwm tam sim no nce. Piv txwv li, yog tias tam sim no ntawm cov khoom lag luam nyob rau hauv ib txwm standby hom yog kaum tawm ntawm microamps, tab sis nws ntsuas ntau pua microamps lossis txawm tias ob peb milliamps, nws qhia tau tias muaj cov khoom tawg hauv Circuit Court. Thaum ntsuas tam sim no, yog tias koj tsis paub meej txog qhov loj ntawm kev khiav hauj lwm tam sim no, koj tuaj yeem pib nrog ntau qhov loj dua thiab maj mam txo nws mus rau qhov ntsuas. Tshaj qhov ntau yuav tau yooj yim hlawv tawm lub fuse ntawm multimeter.
