Kev siv hluav taws xob txheeb xyuas qhov ua haujlwm ntawm multimeter
Hluav taws xob cwj mem kom paub qhov txawv ntawm hluav taws xob hlau thiab xoom kab txoj kev
Ordinary cwj mem: rau kev saib xyuas hluav taws xob yav dhau los txhawm rau txheeb xyuas qhov txhaum, yog tus cwj mem mus thoob plaws ntiaj teb, tus cwj mem zoo tib yam kom paub qhov txawv ntawm qhov hluav taws kub thiab xoom kab, cov neeg feem coob yeej paub, ncaj qha nrog tus cwj mem los ntsuas qhov hluav taws kub thiab xoom kab. , tus cwj mem ci ci rau qhov hluav taws kub, tus cwj mem tsis teeb rau txoj kab xoom!
Cov cwj mem digital: txij li tus cwj mem digital, rau tus cwj mem zoo tib yam tsis tshua siv, rau cov cwj mem digital nta ntau dua, xws li tsis them nyiaj los kuaj xyuas cov kab tawg, paub qhov txawv ntawm xoom thiab hluav taws, paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo DC roj teeb, txiav txim siab seb cov hlau yog luv luv-circuited tuaj yeem ua tau, yog li maj mam tshem tawm ntawm tus cwj mem zoo tib yam, nrog rau cov cwj mem digital kom paub qhov txawv ntawm cov kab hluav taws thiab xoom kab, yog tias koj siv tus cwj mem digital ntsuas ncaj qha nrog tus cwj mem los ntsuas cov kab hluav taws. thiab xoom kab, saib cov cwj mem Voltage, yog tias cov zaub ntawm qhov siab tshaj plaws voltage ntawm 220V, ua pov thawj tias cov hluav taws xob hluav taws xob, yog tias cov khoom siv hluav taws xob siab tshaj plaws ntawm 12V lossis 36V voltage, ua pov thawj tias xoom kab!
Induction breakpoint stylus: lub luag haujlwm tseem ceeb ntawm lub breakpoint stylus yog nrhiav qhov chaw ntawm lub sab hauv breakpoint ntawm txoj kab tom qab cov hlau tsis muaj zog, lub breakpoint stylus distinguishes ntawm kab hluav taws thiab xoom kab, nrog lub breakpoint stylus los ntsuas qhov. hluav taws kab thiab xoom kab, qhov ntsuas qhov ntsuas qhov ntsuas
Multimeter kom paub qhov txawv ntawm kab hluav taws thiab xoom kab txoj kev
Rau lub multimeter yuav muaj AC voltage iav, rau AC voltage iav yuav ntsuas qhov voltage ntawm alternating tam sim no, ntsuas qhov voltage nrog ib tug liab thiab dub cwj mem, ntsig txog, muab tso rau ntawm qhov hluav taws kub kab thiab xoom kab, nws yuav qhia nws voltage, tab sis qhov ntsuas ntawm qhov hluav taws xob, yuav tsum tau muab tso rau hauv qhov tsim nyog iav, xws li kev ntsuas ntawm tsev neeg 220V, 380V voltage, multimeter yuav tsum muab tso rau hauv AC voltage ntawm 700V iav!
Rau AC voltage iav, tsis tsuas yog tuaj yeem ntsuas qhov hluav taws xob, qhov tseeb, tuaj yeem paub qhov txawv ntawm cov hluav taws xob thiab xoom kab. Tsuas yog ntau tus neeg tsis paub nws, multimeter kom paub qhov txawv ntawm kab hluav taws thiab xoom kab, multimeter ntawm AC voltage iav, tus cwj mem dub ntawm ib sab, nrog tus cwj mem liab los ntsuas kab hluav taws thiab xoom kab. , soj ntsuam lub multimeter's digital, digital loj yog cov kab hluav taws xob, cov digital me me yog xoom kab, yog tias koj xav tias tus lej tsis pom tseeb tuaj yeem muab tso rau ntawm lub iav, kho me ntsis, kom tus lej yuav ntau dua. pom tseeb!
