Lub tshuab hluav taws xob twg yog qhov tsim nyog rau kev siv hauv tsev thiab siv tau zoo?
Nws tseem yog analog MF-47 qauv. Txawm hais tias nws yog qhov qub thiab tsis tau txhim kho, ntau cov ntaub ntawv tseem yog raws li lub qub analog saib, tshwj xeeb tshaj yog hauv kev kho cov khoom siv hauv tsev. Raws li tus kws tshaj lij hluav taws xob, nws yooj yim dua los siv lub ntsuas ntsuas analog, vim tias feem ntau cov kws tshaj lij hluav taws xob tsis muaj qhov xav tau siab rau qhov raug, tab sis lawv xav tau kev ntsuas nrawm nrawm, thiab kev nyeem ntawv ntawm lub ntsuas ntsuas digital dhia ib puag ncig yog qeeb. Kuv ua haujlwm tam sim no, thiab kuv feem ntau siv MF47 multimeter thiab ob lub ntsuas digital. Thaum kuv thawj zaug yuav nws, kuv xav tias nws yog tshiab, tab sis dhau sij hawm, kuv pom nws impractical. Nws tau nyob rau hauv lub locker rau ntau xyoo.
Multimeters rau kev siv hauv tsev tsis xav tau qhov tseeb. Koj tuaj yeem yuav ib lub multimeter digital, uas pheej yig heev rau kaum tawm yuan. Rau kev lag luam thiab kev txij nkawm, nws yog qhov zoo dua los siv analog multimeter. Thaum siv cov ntsuas digital, cov lus teb digital qeeb dhau thiab tsis haum. Rau kev ntsuas dav dav, tsuas yog yuav ib lub 'meter' nrog qhov tseeb ntawm 2.5, thiab tus nqi pheej yig heev. Tus nqi ntawm kev saib xyuas siab yuav ntau dua. Seb nws tsim nyog yuav yog nyob ntawm koj cov kev xav tau.
Qhov zaus ntawm kev siv hauv tsev tsawg tsawg, thiab qhov ntsuas qhov ntsuas qhov ntsuas tsis yog siab. Ib tug me me analog multimeter yuav txaus. Yog tias koj muaj peev xwm siv microampere meter los ua tus ntsuas dav dav, nws yooj yim heev. Yog hais tias koj ntxiv tsib diodes, ib tug resistor thiab ib tug ob-ncej ob lub toggle hloov yuav ua tau rau hauv ib tug dual-lub hom phiaj 'meter' rau 22O voltage thiab continuity ntsuas (tau kawg yuav tsum tau ib tug me me roj teeb)
Txiav txim siab qhov ntau thiab qhov tseeb ntawm multimeter raws li qhov voltage, tam sim no, thiab qhov tsis kam ntawm qhov koj ntsuas. Lub multimeter haum rau kev ntsuas hauv tsev muaj qhov voltage ntawm AC60v-500v; DC1v-600v; tam sim no 0.5MA-10A; kuj 1Ω-10kΩ. Nws raug nquahu kom siv MF47 pointer multimeter.
