Multimeter ntsuas qhov tseeb ceev faj
Tib neeg kev nyeem ntawv yuam kev yog ib qho ua rau kev ntsuas qhov tseeb. Nws yog ib qho kev zam tsis tau, tab sis tuaj yeem txo qis. Yog li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them rau cov ntsiab lus hauv qab no hauv kev siv:
(1) Khaws koj ob lub qhov muag perpendicular rau tus pointer thaum nyeem ntawv.
(2) Lub multimeter yuav tsum muab tso rau kab rov tav thiab mechanically zeroed ua ntej ntsuas.
(3) Thaum ntsuas kev tiv thaiv, txhua zaus koj hloov lub iav yuav tsum xoom. Hloov lub roj teeb nrog ib qho tshiab thaum nws tsis xoom; (4) Thaum ntsuas RC circuits, hloov lub roj teeb nrog ib qho tshiab.
(4) Thaum ntsuas qhov kev tiv thaiv hauv RC Circuit Court, txiav tawm lub zog hluav taws xob hauv Circuit Court thiab ntws cov capacitor cov hluav taws xob khaws cia ua ntej ntsuas. Tom qab tshem tawm tib neeg yuam kev hauv kev nyeem ntawv, peb txheeb xyuas lwm yam yuam kev; (5) Thaum ntsuas qhov tsis kam lossis siab voltage, peb yuav tsum hloov lub roj teeb.
(5) Kev ntsuas kev tiv thaiv lossis qhov hluav taws xob siab, koj tsis tuaj yeem tuav cov hlau ntawm tus cwj mem nrog koj txhais tes, yog li tsis txhob shunt tib neeg lub cev tsis kam, nce qhov kev ntsuas yuam kev lossis hluav taws xob poob siab.
Digital multimeter tseem hu ua digital multi-meter (DMM), uas muaj ntau hom thiab qauv. Txhua tus neeg ua haujlwm hauv hluav taws xob xav kom muaj qhov zoo tshaj plaws digital multimeter. Muaj ntau lub hauv paus ntsiab lus rau kev xaiv digital multimeter, thiab qee zaum lawv kuj txawv ntawm ib tus neeg mus rau lwm tus. Tab sis rau lub handheld (pocket) digital multimeter, yuav tsum muaj cov yam ntxwv hauv qab no: cov zaub ntshiab, qhov tseeb, siab daws teeb meem, kev sim ntau yam, ua tiav cov haujlwm ua tiav, muaj peev xwm tiv thaiv kev cuam tshuam, kev tiv thaiv Circuit Court kuj ua tiav, zoo nkauj tsos, siab dav. , yooj yim rau kev khiav lag luam, saj zawg zog, txhim khu kev qha, qis zog noj, portable, pheej yig thiab lwm yam.
