Li cas los ntsuas cov fuse?
Cov txheej txheem yog hloov lub multimeter rau qhov chaw voltage, (AC hloov mus rau AC iav, DC version hloov mus rau DC iav) muaj cai ua ntej kuaj qhov voltage ntawm pawg teeb ntawm ob lub fuses (yuav tsum zoo li qub), thiab tom qab ntawd kuaj piles ntawm ob lub fuses Yog tias pawg teeb lub taub hau pom tias tsis muaj hluav taws xob, nws tuaj yeem txiav txim siab tias qhov fuse raug hlawv.
Koj tuaj yeem tshem ob lub fuses, tom qab ntawd txav lub multimeter mus rau ohmic crotch txoj hauj lwm, siv ob lub meters thiab ob qho los kov ob hnub kawg ntawm lub fuse, thiab nrhiav pom qhov twg fuse raug hlawv tawm. Thaum lub multimeter teb rau qhov tsis kam ntawm lub fuse, nws yog qhov zoo, tus uas tsis muaj kev tiv thaiv yog lub hlawv fuse.
