Multimeter tam sim no thiab voltage ntsuas txoj kev thiab cov kauj ruam
Digital multimeter, tseem hu ua multimeter, multi-meter, multi-meter lossis tri-meter, yog ib qho khoom siv hluav taws xob ntau yam ntsuas, uas feem ntau muaj cov haujlwm xws li ammeter, voltmeter thiab ohmmeter. Piv nrog rau lub pointer multimeter, digital multimeter muaj qhov zoo ntawm high precision, ceev ceev, loj input impedance, digital zaub, nyeem kom raug, muaj zog tiv thaiv kev cuam tshuam, thiab qib siab ntawm kev ntsuas automation thiab yog dav siv. Tab sis yog tias tsis siv kom zoo, nws yooj yim ua rau tsis ua haujlwm. Cia tus kws kho hluav taws xob hauv tsev siv cov multimeter los ntsuas qhov tam sim no thiab voltage txoj kev thiab cov kauj ruam ua ib los ntawm ib qho rau koj los qhia nws.
1, nyob rau hauv kev siv ntawm lub multimeter ua ntej, yuav tsum xub "mechanical zero", uas yog, nyob rau hauv tsis muaj kev ntsuas lub hwj chim, kom lub multimeter pointer nyob rau hauv lub xoom voltage los yog xoom tam sim no txoj hauj lwm.
2, Thaum lub sij hawm tus txheej txheem ntawm kev siv lub multimeter, koj yuav tsum tsis txhob kov cov hlau ib feem ntawm tus cwj mem nrog koj txhais tes, thiaj li yuav xyuas kom meej qhov tseeb ntawm qhov ntsuas ntawm ib sab tes, thiab xyuas kom meej tus kheej kev nyab xeeb ntawm qhov tod tes.
3, Thaum ntsuas qee qhov hluav taws xob, koj tsis tuaj yeem hloov lub iav tib lub sijhawm ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis siab tam sim no, koj yuav tsum tau them sai sai rau nws. Txwv tsis pub, lub multimeter yuav raug puas tsuaj. Yog tias koj xav tau hloov lub zog, koj yuav tsum xub txiav lub cwj mem, hloov lub zog thiab rov qab mus rau qhov ntsuas.
Cov kauj ruam rau ntsuas tam sim no thiab voltage nrog multimeter
1. Xaiv qhov ntau. Multimeter DC voltage iav cim nrog "V", 2.5 volts, 10 volts, 50 volts, 250 volts thiab 500 volts tsib ntau yam. Xaiv qhov ntau raws li qhov loj ntawm lub hwj huam mov voltage hauv Circuit Court. Txij li thaum cov khoom siv hluav taws xob hauv Circuit Court tsuas yog 3 volts, qhov 10-volt ntau yog xaiv. Yog tias koj tsis paub meej txog qhov loj ntawm qhov voltage, koj yuav tsum xub ntsuas nrog lub siab tshaj plaws voltage iav, thiab maj mam hloov mus rau lub zog qis dua iav.
2. Kev ntsuas ntsuas. Multimeter yuav tsum tau txuas nrog nyob rau hauv parallel nrog lub Circuit Court nyob rau hauv kev sim. Tus cwj mem liab yuav tsum tau txuas nrog lub ntsuas hluav taws xob thiab qhov zoo ntawm lub zog hluav taws xob, tus cwj mem dub yuav tsum txuas nrog lub ntsuas hluav taws xob thiab qhov tsis zoo ntawm lub zog hluav taws xob.
3. Kev nyeem ntawv raug. Ua tib zoo saib lub dial, DC voltage nplai yog kab thib ob, nrog 10V cov ntaub ntawv, kab thib peb ntawm cov duab muaj nyob rau hauv kab ntsuas ncaj qha nyeem tawm qhov ntsuas qhov ntsuas hluav taws xob. Nco ntsoov tias thaum nyeem ntawv, kab ntawm qhov pom yuav tsum ncaj qha rau tus taw tes.
