Paub meej: Thaum lub tsheb tsis kuaj xyuas cov khoom siv hluav taws xob, qhov tseem ceeb ntawm kev ua haujlwm tsis zoo yog ntsuas cov ntaub ntawv thiab cov txheej txheem kev xav. Tsis zoo li cov ntaub ntawv ntawm cov khoom siv hluav taws xob, cov khoom siv kho tshuab sab hauv tuaj yeem qhib kom pom, thiab siv cov kauj ruam tsim nyog thiab cov laj thawj uas tuaj yeem tshawb pom cov teeb meem sai sai hauv cov txheej txheem no yog cov cuab yeej tseem ceeb hauv multimeter. Ib txwm multimeter tuaj yeem kuaj qhov voltage, tsis kam, tam sim no, tsis haum rau kev kho tsheb niaj hnub thiab kev tshuaj xyuas cov khoom siv hluav taws xob hauv hluav taws xob rau cov khoom siv kho tsheb ntawm kev lag luam tam sim no nrog cov multi-function digital multimeter tsheb muaj ntau yam tshwj xeeb kuaj tsheb hluav taws xob ua haujlwm, xws li Raws li zaus, lub voj voog ua haujlwm, lub siab dav, qhov kub thiab txias thiab lwm yam-Ntawm no yog cov khoom siv hluav taws xob tswj tau ntau qhov kev ua haujlwm digital multimeter ntawm cov khoom siv hluav taws xob, kev kuaj cav, rau feem ntau ntawm cov tsheb tu engineering thiab cov tub ceev xwm.
