Txoj kev thiab cov kauj ruam rau ntsuas tam sim no thiab voltage nrog ib tug multimeter
Lub tshuab hluav taws xob digital, tseem hu ua multimeter, multimeter, multimeter lossis peb lub hom phiaj ntsuas, yog cov khoom siv hluav taws xob ntau lub hom phiaj uas feem ntau suav nrog ammeter, voltmeter, ohmmeter thiab lwm yam haujlwm. Piv nrog rau pointer multimeters, digital multimeters 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 tau dav siv. Txawm li cas los xij, yog tias siv tsis raug, nws yuav ua rau muaj teeb meem. Cia tus kws kho hluav taws xob hauv tsev qhia rau koj ib qho los ntawm ib qho ntawm cov txheej txheem thiab cov kauj ruam ntawm kev siv multimeter los ntsuas qhov tam sim no thiab qhov hluav taws xob.
1. Ua ntej siv lub multimeter, koj yuav tsum xub ua "txhim kho xoom xoom", uas yog, thaum tsis muaj hluav taws xob ntsuas, lub multimeter pointer yuav tsum taw tes ntawm xoom voltage lossis xoom txoj haujlwm tam sim no.
2. Thaum siv lub tshuab multimeter, tsis txhob kov cov hlau ntawm cov hlau lead ntawm koj txhais tes. Qhov no tuaj yeem ua kom ntsuas qhov tseeb ntawm ib sab tes, thiab kev nyab xeeb ntawm tus kheej ntawm qhov tod tes.
3. Thaum ntsuas qee qhov hluav taws xob, koj tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis tam sim no loj, koj yuav tsum tau them sai sai. Txwv tsis pub, lub multimeter yuav puas. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev sim ua ntej, thiab tom qab ntawd ntsuas tom qab hloov lub zog.
Cov kauj ruam los ntsuas tam sim no thiab voltage siv lub multimeter
1. Xaiv qhov ntsuas qhov ntsuas. DC voltage ntau ntawm multimeter yog cim nrog "V" thiab muaj tsib yam: 2.5 volts, 10 volts, 50 volts, 250 volts thiab 500 volts. Xaiv qhov ntau raws li qhov hluav taws xob muab hluav taws xob voltage hauv Circuit Court. Txij li thaum lub hwj chim mov voltage nyob rau hauv lub Circuit Court tsuas yog 3 volts, 10 volt ntau yog xaiv. Yog tias koj tsis paub qhov voltage, koj yuav tsum xub ntsuas nrog qib siab tshaj plaws thiab maj mam hloov mus rau qib qis dua.
2. Cov txheej txheem ntsuas. Lub 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 kev sib txuas ntawm lub voj voog nyob rau hauv kev sim thiab tus ncej zoo ntawm lub hwj huam mov, thiab tus cwj mem dub yuav tsum tau txuas nrog kev sib txuas ntawm lub voj voog nyob rau hauv kev sim thiab tus ncej tsis zoo ntawm lub hwj huam mov.
3. Kev nyeem ntawv raug. Ua tib zoo saib lub dial. DC voltage scale kab yog kab thib ob. Thaum siv qhov ntsuas 10V, koj tuaj yeem nyeem ncaj qha rau qhov ntsuas qhov ntsuas hluav taws xob los ntawm kev siv kab thib peb ntawm cov lej hauv qab kab. Thaum nyeem ntawv, koj ob lub qhov muag yuav tsum tig mus rau lub pointer.
