Yuav ua li cas siv ib tug multimeter los ntes luv luv thiab qhib circuits
Multimeter yog qhov tsim nyog "cov tub ntxhais kawm nyuaj" rau cov phooj ywg koom nrog hauv hluav taws xob, hluav taws xob, thiab kev saib xyuas. 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 tau siv ib tug multimeter. los pab nrhiav teeb meem.
Thaum cov khoom lag luam ua haujlwm tsis zoo, kuv feem ntau siv qhov ntsuas hluav taws xob 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 yog qhov qub. Qhov voltage yog txawv txav, thiab feem ntau muaj luv luv Circuit Court lossis qhib Circuit Court.
luv Circuit Court los yog qhib Circuit Court kuaj los ntawm buzzer iav
Ib qho digital multimeter feem ntau muaj lub buzzer, thiab thaum txuas nrog, nws yuav suab "BI", 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" lossis "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" lossis "BI" suab tawm, nws qhia tau tias muaj qhov qhib Circuit Court;
Yog tias koj lub multimeter tsis muaj ntau yam buzzer, koj tuaj yeem siv qhov kev tiv thaiv ntau los txiav txim seb puas muaj luv luv lossis qhib Circuit Court los ntawm kev ntsuas tus nqi 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 loj heev, nws qhia tau hais tias qhib Circuit Court.
Thaum siv lub buzzer los yog kev tiv thaiv ntau yam rau kev ntsuas, nco ntsoov disconnect lub hwj chim ua ntej!
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 tam sim no hais txog kev xau ntawm AC high voltage, uas tuaj yeem ua rau hluav taws xob rau ib tus neeg lossis ua rau lub xau hloov mus rau qhov chaw. Lub multimeter tuaj yeem teeb tsa rau AC ntau yam los ntsuas qhov muaj qee qhov AC voltage. Lwm txoj hauv kev yog txiav tawm cov khoom siv hluav taws xob thiab ntsuas qhov kev tiv thaiv tus nqi ntawm cov xaim xaim thiab cov xaim nyob (L) lossis xoom xaim (N) siv qhov siab tshaj plaws tiv thaiv ntau yam. Yog tias tsis muaj qhov xau, qhov kev tiv thaiv tus nqi yog siab heev, sib npaug rau rwb thaiv tsev. Yog tias tus nqi tiv thaiv rau hauv av tsis loj txaus thiab tus nqi tiv thaiv ntawm ntau pua K ntsuas, 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 ntau yam ntawm multimeter los txuas cov multimeter hauv series rau hauv Circuit Court thiab ntsuas seb qhov ua haujlwm tam sim no puas tau nce. Piv txwv li, thaum cov khoom nyob rau hauv ib txwm standby hom, tam sim no yog ob peb kaum ntawm microamps, tab sis qhov ntsuas tam sim no yog ob peb puas microamps, los yog txawm ob peb milliamps, uas qhia tau hais tias muaj to hauv Circuit Court. Yog tias koj tsis paub meej txog qhov loj ntawm kev ua haujlwm tam sim no thaum ntsuas qhov tam sim no, koj tuaj yeem pib nrog lub iav nrog ntau qhov loj dua ua ntej, thiab tom qab ntawd maj mam txo qhov ntau los kuaj. Overrange tau yooj yim hlawv tawm lub fuse ntawm multimeter.
Dab tsi yog lwm txoj haujlwm uas lub multimeter muaj?
Lub multimeter muaj ntau yam haujlwm, xws li ntsuas qhov ntsuas, diodes, LEDs, transistors, thiab txawm txuas cov thermocouples los ntsuas qhov kub thiab txias. Tau kawg, tsis yog txhua tus multimeters muaj lub zog zoo li no, thiab nws nyob ntawm tus qauv tshwj xeeb
