Kev ntsuas qhov yuam kev ntawm qhov tam sim no thiab qhov tsis kam siv lub multimeter
Thaum ntsuas nrog multimeter, tej zaum yuav muaj qee qhov yuam kev. Qee qhov yuam kev no yog qhov yuam kev siab tshaj plaws uas tau tso cai los ntawm qib raug ntawm qhov ntsuas nws tus kheej.
Qee qhov yog Tus Kheej sib npaug tshwm sim los ntawm kev hloov kho thiab siv tsis raug. Los ntawm kev nkag siab zoo txog cov yam ntxwv ntawm multimeter thiab cov laj thawj ntawm kev ntsuas qhov yuam kev, kev paub txog cov txheej txheem ntsuas thiab cov txheej txheem kom raug, ntsuas qhov yuam kev tuaj yeem raug txo.
Tib neeg kev nyeem ntawv yuam kev yog ib qho laj thawj uas cuam tshuam rau kev ntsuas qhov tseeb. Nws yog inevitable, tab sis nws tuaj yeem txo qis kom ntau li ntau tau. Yog li ntawd, tshwj xeeb yuav tsum tau them rau:
1. Ua ntej ntsuas, lub multimeter yuav tsum muab tso rau kab rov tav thiab mechanically zeroed;
2. Khaws koj ob lub qhov muag perpendicular rau lub pointer thaum nyeem ntawv;
3. Thaum ntsuas qhov tsis kam, xoom yuav tsum tau hloov kho txhua zaus lub iav hloov. Hloov lub roj teeb nrog ib qho tshiab yog tias nws tsis tuaj yeem hloov mus rau xoom;
4. Thaum ntsuas qhov tsis kam lossis siab voltage, nws tsis raug tso cai tuav cov hlau ib feem ntawm lub ntsuas ntsuas nrog koj txhais tes los tiv thaiv tib neeg lub cev tiv thaiv los ntawm diverging, nce kev ntsuas yuam kev lossis hluav taws xob poob siab;
5. Thaum ntsuas qhov kev tiv thaiv nyob rau hauv RC Circuit Court, txiav tawm lub hwj chim mov nyob rau hauv lub Circuit Court thiab tso tawm cov hluav taws xob nyob rau hauv lub capacitor ua ntej ntsuas.
Tom qab tsis suav nrog tib neeg kev nyeem ntawv yuam kev, peb tau ua qee qhov kev tshuaj xyuas ntawm lwm qhov yuam kev.
ib qho, Xaiv qhov voltage thiab tam sim no ntau yam thiab ntsuas qhov yuam kev ntawm multimeter
Cov qib raug ntawm multimeter feem ntau muab faib ua ntau theem, xws li {{0}}.1, 0.5, 1.5, 2.5, thiab 5. Kev ntsuas qhov tseeb ntawm qib rau ntau lub zog xws li DC voltage, tam sim no , AC voltage, thiab tam sim no yog sawv cev los ntawm qhov siab tshaj plaws tso cai yuam kev △ X thiab feem pua ntawm cov nqi xaiv tag nrho. Qhia los ntawm cov mis: A feem pua =(△ X/tag nrho cov nqi) × 100 feem pua ... 1
(1) Qhov yuam kev tshwm sim los ntawm kev ntsuas tib qhov hluav taws xob siv lub tshuab multimeter nrog qhov tseeb sib txawv
(2) Qhov yuam kev tshwm sim los ntawm kev ntsuas tib qhov hluav taws xob siv ntau qhov sib txawv ntawm multimeter
(3) Qhov yuam kev tshwm sim los ntawm kev ntsuas ob qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm ib qho multimeter
