Yuav ua li cas siv digital multimeter, yuav ua li cas siv digital multimeter
Kev nkag siab ntawm kev sim thiab ntsuas qhov voltage
Kev ntsuas hluav taws xob tuaj yeem muab faib ua qhov ntsuas DC voltage thiab ntsuas AC voltage, thaum kuaj thiab ntsuas tam sim no tuaj yeem muab faib ua kev ntsuas thiab ntsuas DC tam sim no thiab ntsuas thiab ntsuas AC tam sim no. Ua ntej ntawm tag nrho cov, koj yuav tsum tau ceev faj thaum koj kuaj lub hwj chim mov voltage. Thaum ntsuas qhov voltage, koj yuav tsum xub txiav txim seb qhov koj tab tom sim yog AC voltage lossis DC voltage. Ntawm no kuv xav qhia rau sawv daws paub txog kev paub. Cov khoom siv pej xeem yog tag nrho AC. Txawm li cas los xij, chargers xws li xov tooj ntawm tes thiab lwm yam chargers tso tawm DC voltage, uas ua rau qhov kev ntsuam xyuas me ntsis teeb meem. Yog li, koj yuav tsum paub qhov txawv seb nws yog AC lossis DC ua ntej ntsuas. Yog tias koj ntsuas Yog tias koj tsis paub tias qhov hluav taws xob puas yog qhov hluav taws xob tiag tiag lossis tam sim no, ces koj yuav tsum muab tso rau hauv qhov chaw AC yog tias muaj ntau yam teeb meem tshwm sim thaum kuaj. Lub sijhawm no, koj yuav tsum maj mam kho thiab hloov ntawm lub iav siab tshaj plaws mus rau qhov tsawg kawg nkaus iav kom txog thaum koj ncav cuag tus nqi koj xav tau. Thaum koj thawj zaug pib siv cov cuab yeej ntsuas no, qib raug tsis tseem ceeb heev. Koj yuav tsum nco ntsoov cov teeb meem tseem ceeb. Tus yuam sij Nws nyob ntawm seb qhov kev xaiv iav yog qhov tseeb thiab seb lub tshuab hluav taws xob multimeter puas zoo ib yam. Yog tias koj yuam kev ntxig cov hlau lead mus rau hauv lub jack tam sim no thaum ntsuas qhov hluav taws xob, ces koj raug ntsia hlau, vim tias qhov kev ntsuas tsis raug yuav ua rau lub iav tam sim no hloov. Yuav tsum tau hlawv. Tsis tas li ntawd, thaum koj ua tiav kev sim multimeter, koj yuav tsum tsim tus cwj pwm zoo. Txhua zaus koj siv lub multimeter, koj yuav tsum hloov lub iav mus rau AC voltage ntau * thiab ntxig qhov kev xeem coj mus rau hauv qhov hluav taws xob qhov hluav taws xob. Qhov no yog ib tug cwj pwm zoo * Nws yog qhov zoo los txhim kho nws, thiab nws tseem yuav pab tau zoo rau kev ua haujlwm yav tom ntej. Txwv tsis pub, koj yuav tau them tus nqi kawm ntawv.
