Kev Nyab Xeeb Cov Qauv Kev Nyab Xeeb Qauv thiab kev siv cov kev ua kom digital
Thaum koj pom cov cim zoo li UL, CSA, TUV, lossis nyeem cov lus xws li 'tsim qauv kom tau raws li ...', koj feem ntau xav txog kev kawm ywj siab thiab cov ntawv pov thawj kev pov thawj. Koj tuaj yeem ua pov thawj li cas tias koj cov digital multimeter ua tau raws li cov qauv kev nyab xeeb thiab Catii? Nws yog qhov ntau heev uas cov chaw tsim tshuaj paus ntseeg lawv saib xyuas tau raws li Catia II lossis catia Kuv cov qauv, tab sis tsis tau muaj ntawv pov thawj ywj pheej. Txoj Cai Hluav Taws Xob Electrotechnical thoob ntiaj teb (IEC) tsuas yog tsim thiab pom zoo nws cov qauv, tab sis tsis yog lub luag haujlwm los tswj lawv. Tsuas yog thaum ib qho khoom lag luam tau raug sim thiab ua tiav cov qauv ntawm cov koom haum ywj pheej, tuaj yeem yog cov cim pov thawj kev pov thawj xws li ul, CSA, Tuv, thiab lwm yam cim tau. Hauv kev ua lag luam sib xyaw ua lag luam, kev xeem ntawv ywj siab thiab cov ntawv pov thawj ywj pheej yuav tsis yog qhov zoo tshaj plaws, tab sis nws yuav yog qhov ncaj qha ntawm kev txheeb xyuas tus kheej.
Txhawm rau kom muaj kev nyab xeeb siv cov digital motimeter, thawj kauj ruam yog xaiv cov digital mottimeter uas haum rau daim ntawv thov thiab ua tau raws li ib puag ncig kev thov. Thaum koj tau xaiv qhov tsim nyog digital motimeter, koj yuav tsum siv nws raws li cov ntaub ntawv thov ib txwm muaj. International Electrotechnical Association tau tsim cov qauv tshiab rau kev ua haujlwm hauv lub zog hluav taws xob. Paub meej tias cov digital motulions koj siv tau raws li IEC cov qauv thiab nws cov ntsuas hluav taws xob thiab nws cov ntsuas hluav taws xob tau raws li kev xav tau rau ntawm-}} chaw app. Piv txwv li, yog ntsuas ntsuas tus vaj huam sib luag 480v lub zog muaj zog, koj cov qauv siv hluav taws xob, uas txhais tau tias qhov kev siv hluav taws xob tau ua kom pom cov khoom siv ntawm daim ntawv thov no yam tsis muaj kev sib raug zoo. Xaiv lub digital motically sau npe nrog UL, CSA, Tut, Tuv txhais tau tias cov qauv IEC nkaus xwb, tab sis kuj tsis muaj kev sib tw ntawm cov qauv ntawm kev ywj pheej.
