Ntawm no yog cov lus piav qhia luv luv ntawm kev ua haujlwm yooj yim ntawm kev ntsuas kev tiv thaiv nrog multimeter
1, Ua ntej xaiv qhov ntau ntawm multimeter hauv thaj tsam ntawm cov ntaub ntawv tiv thaiv, thiab xaiv qhov loj dua hauv qhov tseem ceeb.
2, multimeter sab hauv lossis cwj mem kab nws tus kheej muaj qee qhov kev tiv thaiv, txhawm rau ntsuas qhov ntsuas tus nqi ntawm cov khoom siv hluav taws xob ntsuas, thawj kauj ruam yog ntsuas nws cov kev tiv thaiv sab hauv, cov cwj mem liab thiab dub hauv kev sib cuag nrog ib leeg, Tus nqi nyeem tawm los ntawm multimeter yog qhov kev tiv thaiv sab hauv ntawm multimeter nws tus kheej, nyob rau hauv ib txwm muaj xwm txheej, sab hauv tsis kam ntawm 2 ohms hauv qab no.
3. koj tuaj yeem txiav lub roj teeb lub zog.
4, yuav txuas nrog multimeter cwj mem thiab ntsuas cov khoom, thiab tom qab ntawd kho cov iav hauv qhov qub, yog tias koj tsis paub qhov kev tiv thaiv ntawm cov khoom siv ntsuas, koj tuaj yeem ntsuas los ntawm ntau yam me me, yog tias muaj ntau qhov ntau ntawm cov nqi qhia raws li 0.00, uas yog, lub iav loj dua, koj tuaj yeem txuas ntxiv kho qhov me me, ntsuas qhov tsis kam.
5, thaum kawg, lub multimeter qhia tau hais tias tus nqi ib txwm ntsuas los yog kab nrog lub multimeter nws tus kheej cov txiaj ntsig ntawm qhov kev tiv thaiv, lub sij hawm no siv tus nqi rho tawm cov kev tiv thaiv sab hauv ntawm multimeter kom tau txais qhov tsis kam ntawm cov ntsuas ntsuas, xws li qhov ntsuas ntsuas tus nqi ntawm 2.6 rho tawm 0.4 nyob rau hauv daim duab no, qhov tseeb kuj tus nqi yog 2.2.
Multimeter los ntsuas qhov tsis kam ntawm qhov kev tiv thaiv tus nqi ntawm kev ceev faj:
(1) nyob rau hauv kev siv lub multimeter yuav tsum tau nqa tawm ua ntej lub "mechanical zero", uas yog, nyob rau hauv tsis muaj kev ntsuas lub hwj chim, kom lub multimeter pointer nyob rau hauv txoj hauj lwm ntawm xoom voltage los yog xoom tam sim no.
(2) Nyob rau hauv 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 kev 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. Txwv tsis pub, lub multimeter yuav raug puas tsuaj. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav lub ntsuas ntsuas ntsuas ua ntej thiab hloov lub zog ua ntej ntsuas.
(4) Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, nws yuav tsum tau sau tseg kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm multimeter.
