Cov txheej txheem thiab cov cuab yeej rau ntsuas tam sim no thiab voltage nrog multimeter
Lub multimeter, tseem hu ua multimeter, multimeter, multimeter, los yog multimeter, yog ib tug multi-purpose electronic ntsuas ntsuas uas feem ntau muaj xws li functions xws li ammeter, voltmeter, ohmmeter, thiab lwm yam. vim lawv qhov raug siab, ceev ceev, loj input impedance, digital zaub, nyeem kom raug, muaj peev xwm tiv thaiv kev cuam tshuam, thiab qib siab ntawm kev ntsuas automation. Tab sis yog tias siv tsis raug, nws tuaj yeem ua rau tsis zoo. Cia tus editor ntawm Hluav Taws Xob Lub Tsev qhia txog cov txheej txheem thiab cov kauj ruam ntawm kev siv lub tshuab ntsuas ntsuas ntsuas tam sim no thiab qhov hluav taws xob ib qho los ntawm ib qho.
1. Ua ntej siv multimeter, nws yog ib qho tsim nyog yuav tsum tau ua ib qho "mechanical zeroing", uas txhais tau hais tias thaum tsis muaj lub hwj chim ntsuas, lub multimeter pointer yuav tsum muab tso rau ntawm xoom voltage lossis xoom tam sim no txoj hauj lwm.
2. Thaum lub sij hawm siv multimeter, tsis txhob kov cov hlau ntawm qhov kev sojntsuam nrog koj txhais tes. Qhov no ua kom qhov ntsuas qhov tseeb thiab kev nyab xeeb ntawm tus kheej.
3. Thaum ntsuas qee qhov hluav taws xob, nws tsis pom zoo kom hloov lub zog ntawm tib lub sijhawm, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis siab tam sim no. Txwv tsis pub, nws yuav ua puas lub multimeter. Yog tias koj xav tau hloov lub zog, tshem tawm qhov kev sojntsuam 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 ntau. 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 yam raws li qhov voltage ntawm lub hwj chim mov hauv Circuit Court. Vim lub fact tias lub hwj chim mov voltage nyob rau hauv lub Circuit Court tsuas yog 3 volts, lub 10 volt ntau yam yog xaiv. Yog tias qhov ntsuas hluav taws xob tsis meej, qhov siab tshaj qhov ntsuas hluav taws xob yuav tsum tau siv rau kev ntsuas ua ntej, thiab maj mam hloov mus rau qhov qis qis dua.
2. Kev ntsuas ntsuas. Lub multimeter yuav tsum tau txuas nrog nyob rau hauv parallel nrog lub xeem Circuit Court. Tus cwj mem liab yuav tsum tau txuas nrog lub davhlau ya nyob twg zoo ntawm qhov ntsuas hluav taws xob thiab lub zog hluav taws xob, thiab tus cwj mem dub yuav tsum tau txuas nrog lub davhlau ya nyob twg tsis zoo ntawm qhov ntsuas hluav taws xob thiab lub zog hluav taws xob.
3. Nyeem kom raug. Ua tib zoo saib lub dial, DC voltage theem scale kab yog kab thib ob. Thaum siv 10V qib, ntsuas tus nqi hluav taws xob tuaj yeem nyeem ncaj qha siv kab thib peb ntawm cov lej hauv qab kab. Ua tib zoo mloog rau kev nyeem ntawv, thiab koj txoj kab ntawm qhov pom yuav tsum tig mus rau lub pointer.
