Qhov twg multimeter rau hluav taws xob tsim nyog rau tsev thiab muaj nqi ntau dua?
Nws tseem yog tus pointer MF-47. Txawm hais tias nws yog qhov qub, thiab nws tsis tau txhim kho txhua lub sijhawm, ntau cov ntaub ntawv yog ua raws li cov lus qhia qub no, tshwj xeeb tshaj yog hauv kev saib xyuas cov khoom siv hauv tsev. Nws yog qhov yooj yim dua los siv lub ntsuas ntsuas ntsuas raws li tus kws tshaj lij hluav taws xob, vim tias cov tshuab hluav taws xob feem ntau tsis tas yuav muaj qhov raug siab, tab sis lawv xav tau kev ntsuas nrawm ntawm kev tawm-tawm thiab dhia nyeem cov ntsuas ntsuas tau qeeb dua. Kuv yog ib tug hluav taws xob tam sim no, thiab kuv feem ntau siv MF47 multimeter. Muaj ob lub ntsuas digital. Kuv pom lawv tshiab thaum kuv xub yuav lawv, tab sis kuv pom lawv ua tsis tau tom qab ntev. Kuv tau kaw lawv hauv lub txee rau ntau xyoo.
Lub multimeter rau kev siv hauv tsev tsis xav tau qhov tseeb. Tsuas yog yuav ib qho digital multimeter casually, thiab nws pheej yig heev rau kaum tawm yuan. Nws yog qhov zoo dua los siv pointer multimeter rau kev siv thiab tu. Thaum siv kev ntsuas digital, qhov kev xav ntawm digital yog qeeb heev, yog li nws tsis siv. Feem ntau, nws txaus los 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 qhov xav tau.
Qhov zaus ntawm kev siv tsev neeg tsawg, thiab qhov ntsuas qhov tseeb tsis siab. Feem ntau, me me pointer universal meter yuav ua. Yog tias koj muaj peev xwm ua tau ib lub ntsuas universal nrog microamp meter, nws yooj yim heev. Yog tias koj ntxiv tsib lub diodes, tus resistor thiab ob-ncej, ob-txoj kev hloov pauv, koj tuaj yeem ua ob lub hom phiaj ntsuas nrog 22O qhov hluav taws xob thiab kev ntsuas hluav taws xob (qhov tseeb, koj yuav tsum muaj lub roj teeb me me).
Txiav txim siab lub iav thiab qhov tseeb ntawm lub multimeter raws li qhov voltage, tam sim no thiab tsis kam ntau yam koj ntsuas. Lub multimeter haum rau hauv tsev yog siv los ntsuas qhov voltage hauv AC60v-500v; Hauv DC DC1v-600v; Tam sim no nyob rau hauv 0.5MA-10A; Qhov tsis kam yog nyob rau hauv 1Ω-10kΩ. Nws raug nquahu kom siv MF47 pointer multimeter.
Lub rooj sib tw hauv tsev yog qhov zoo, pheej yig thiab siv tau, tab sis yuav muaj qhov yuam kev hauv kev siv cov ntaub ntawv tiv thaiv, thiab qhov tseeb yog tsis muaj teeb meem hauv daim ntawv thov txhua hnub. Kuv tau siv nws, thiab lub buzzer nrov, yog li nws yooj yim heev los xyuas qhov luv luv thiab qhib Circuit Court.
