Yuav ua li cas siv cov kev txheeb xyuas nyob hauv xov tooj ntawm multimeter
Cov neeg siv hluav taws xob tau siv cov cwj mem hluav taws xob rau kev saib xyuas thiab daws teeb meem, tab sis tam sim no lawv siv multimeters. Qhov tseeb, tsis yog tsuas yog tus cwj mem hluav taws xob tuaj yeem paub qhov txawv ntawm cov xaim nyob nruab nrab ntawm cov hlau tsis huv, tab sis cov multimeter kuj tseem tuaj yeem paub qhov txawv ntawm cov hlau nyob nruab nrab, tab sis ntau tus neeg tsis paub.
Txoj kev paub qhov txawv ntawm cov hlau nyob thiab xoom xaim los ntawm hluav taws xob cwj mem
Ordinary electric cwj mem: Rau kev kho hluav taws xob thiab kev daws teeb meem yav dhau los, ib tus cwj mem hluav taws xob tau siv thoob plaws ntiaj teb. Cov cwj mem hluav taws xob zoo tib yam qhia qhov txawv ntawm cov hlau nyob thiab cov xaim nruab nrab. Cov hlau nyob, tus cwj mem hluav taws xob tsis teeb, nws yog cov xaim nruab nrab
Cov cwj mem hluav taws xob digital: Txij li cov cwj mem hluav taws xob digital muaj, nws tsis tshua siv rau cov cwj mem hluav taws xob zoo tib yam. Rau cov cwj mem hluav taws xob digital, nws muaj ntau txoj haujlwm, xws li tshuaj xyuas cov xov hlau tawg tsis muaj hluav taws xob, paub qhov txawv ntawm cov xov hlau tsis zoo thiab cov xov hlau nyob, paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo ntawm DC roj teeb, thiab txiav txim seb cov xov hlau puas luv luv. Nws yog tag nrho, yog li ntawd tus cwj mem hluav taws xob zoo tib yam tau maj mam tshem tawm. Yog tias koj siv tus cwj mem hluav taws xob digital kom paub qhov txawv ntawm cov xaim nyob thiab cov xaim nruab nrab, koj tuaj yeem siv tus cwj mem hluav taws xob ncaj qha los ntsuas cov xaim nyob thiab cov xaim nruab nrab, thiab saib xyuas qhov voltage ntawm tus cwj mem hluav taws xob. Yog tias qhov siab tshaj plaws qhov hluav taws xob tso tawm yog 220V, nws ua pov thawj tias nws yog cov hlau nyob. Yog tias qhov hluav taws xob siab tshaj plaws yog 12V lossis 36V, nws ua pov thawj tias yog cov kab nruab nrab
Inductive breakpoint ntsuas cwj mem: lub luag haujlwm tseem ceeb ntawm tus cwj mem breakpoint yog nrhiav txoj haujlwm ntawm qhov tawg hauv kab tom qab cov hlau tsis muaj zog. Thaum tus cwj mem hluav taws xob ntsuas cov hlau nyob, lub suab kuj nrawm, thiab thaum ntsuas qhov nruab nrab, lub suab kuj qeeb.
