Yuav ua li cas kuaj luv Circuit Court thiab qhib Circuit Court nrog ib tug multimeter
Multimeter yog ib qho tseem ceeb "hardcore" cov cuab yeej rau cov phooj ywg koom hauv electronics, hluav taws xob engineering, thiab kev saib xyuas muaj feem xyuam. Nws muaj cov haujlwm muaj zog heev thiab tuaj yeem siv los ntsuas AC voltage, DC voltage, AC tam sim no, DC tam sim no, tsis kam, capacitance, diode, transistor, kub, thiab lwm yam. Piv txwv li, thaum kuaj thiab debugging cov khoom, peb yuav tsum siv lub multimeter los pab nrhiav teeb meem.
Thaum cov khoom lag luam ua haujlwm tsis zoo, Kuv feem ntau ntsuas qhov kev tawm tswv yim thiab cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob los txiav txim seb lub hwj chim hluav taws xob puas ua haujlwm zoo. Qhov txawv txav tsis zoo feem ntau qhia tias luv luv lossis qhib Circuit Court.
Buzzer iav xeem rau luv luv Circuit Court thiab qhib Circuit Court
Ib qho digital multimeter feem ntau muaj hom buzzer, uas yuav suab "BI" thaum txuas nrog, uas yog intuitive heev thiab tsis tas yuav saib ntawm lub multimeter.
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, tab sis tsis muaj "BI" suab, nws qhia tau hais tias muaj lub tshuab hluav taws xob;
Yog tias koj lub multimeter tsis muaj hom buzzer, koj tuaj yeem siv hom kev tiv thaiv los txiav txim siab seb puas muaj qhov luv luv lossis qhib Circuit Court raws li txoj kev ntsuas kev tiv thaiv. Yog tias qhov tsis kam ua me me, tsuas yog ob peb ohms, lossis txawm tias ob peb feem kaum ntawm ohm, nws qhia tau hais tias luv luv; Yog tias tus nqi tiv thaiv tsis tuaj yeem ntsuas los yog siab heev, nws qhia tau tias muaj qhov qhib Circuit Court.
Kev ntsuas qhov dej
Cov dej xau tau muab faib ua qhov muaj zog tam sim no thiab tsis muaj zog tam sim no. Lub zog hluav taws xob xau yog hais txog qhov xau ntawm AC high voltage, uas tuaj yeem ua rau hluav taws xob rau tib neeg lossis ua rau lub xau hloov mus rau qhov chaw. Koj tuaj yeem teeb lub multimeter rau AC hom los ntsuas seb puas muaj qee qhov AC voltage. Lwm txoj hauv kev yog tshem tawm cov khoom siv hluav taws xob thiab ntsuas qhov kev tiv thaiv ntawm cov xaim xaim thiab cov xaim nyob (L) lossis cov xaim nruab nrab (N) siv qhov siab tshaj plaws ntawm kev tiv thaiv. Yog tias tsis muaj qhov to, qhov kev tiv thaiv tus nqi yog siab heev, sib npaug rau rwb thaiv tsev. Yog tias qhov kev tiv thaiv rau hauv av tsis loj txaus thiab qhov ntsuas tus nqi ntawm ntau puas K, ces tej zaum yuav muaj qhov xau.
Yog tias koj xav ntsuas qhov tsis muaj zog ntawm cov hluav taws xob tsis muaj zog tam sim no, koj tuaj yeem siv qhov tam sim no ntawm multimeter, txuas lub multimeter hauv series rau hauv Circuit Court, thiab ntsuas seb qhov ua haujlwm tam sim no tau nce. Piv txwv li, thaum cov khoom nyob rau hauv ib txwm standby hom, tam sim no yog ob peb kaum ntawm microamperes, tab sis thaum nws yog ntsuas los ntawm ntau pua microamperes los yog txawm ob peb milliamps, nws qhia tau hais tias muaj cov khoom uas muaj to hauv Circuit Court. Yog tias koj tsis paub meej txog qhov loj ntawm kev ua haujlwm tam sim no thaum ntsuas tam sim no, koj tuaj yeem pib nrog lub iav nrog ntau qhov loj thiab maj mam txo qhov ntau los kuaj. Tshaj qhov ntau yuav tau yooj yim hlawv tawm lub fuse ntawm multimeter.
