Txoj Kev Ntsuas Cov Zero thiab Nyob Hlau nrog Digital Multimeter
Nws yog qhov yooj yim heev los siv lub tshuab ntsuas ntsuas los ntsuas qhov nruab nrab thiab nyob ntawm lub tsev, tsuav yog koj siv lub tshuab digital multimeter, clamp-type multimeter, lossis AC voltage ntau ntawm pointer mechanical multimeter. Qhov kev hloov pauv ntawm multimeter yog teem rau AC voltage ntau (tag nrho cov multimeters yuav tsum muaj qhov no, qhov ntau yog los ntawm 200mV mus rau 750V, feem ntau xaiv 200V ntau, qee qhov clamp meters tsis muaj 200V ntau, koj tuaj yeem xaiv qhov loj dua. ntau.
Lub iav ntawm lub pointer multimeter yuav tsum me dua, koj tuaj yeem xaiv 10 V 100V), thiab tom qab ntawd ntxig cov xim liab thiab xim dub coj mus rau hauv V / COM (lub jack rau ntsuas 220V voltage ntawm cov khoom siv hauv tsev nyob rau lub sijhawm zoo tib yam), thiab cua tshuab. dub test lead hlau nyob rau sab laug tes rau 2-3 lem (saib daim duab ) Tau kawg, qhov ntau qhov zoo, xyuam xim: lub sij hawm no, lub koob hlau ntawm tus cwj mem dub yuav tsum tsis txhob kov koj ob txhais tes, nyob rau hauv rooj plaub no ntawm hluav taws xob poob siab, tom qab ntawd koj tuaj yeem sim, coj tus cwj mem liab los kuaj lub qhov (socket) lossis xoom nyob hauv xov tooj raws li, thiab koj sau ob qhov kev ntsuas raws li qhov tshwm sim, yuav tsum muaj qhov loj thiab me voltage ntawm lawv. Qhov loj voltage ntsuas yog txoj kab nyob, thiab qhov me me voltage tus nqi yog ntawm cov kab nruab nrab. Yog tias cov kab hauv av yuav tsum tsis muaj qhov hluav taws xob me me lossis txawm tias tsis muaj qhov hluav taws xob (nyob ntawm koj lub tsev) Cov xaim hauv av tsis txuas!) Qhov txawv ntawm qhov ntsuas qhov ntsuas hluav taws xob ntawm cov hlau nruab nrab thiab cov xaim nyob yog qhov tseeb ntawm ib nrais muag.
