Kev daws teeb meem ntawm multimeter
Kev daws teeb meem yog hais txog qhov kev hloov pauv yam tsawg kawg nkaus hauv cov teeb liab tawm tswv yim uas tuaj yeem ua rau cov teeb liab tso zis hloov. Thaum qhov ntau ntawm DMM raug txo, qhov kev daws teeb meem yuav raug txhim kho. Txawm li cas los xij, thaum kawg koj xav kom koj lub multimeter tso saib ntsuas kev nyeem ntawv ntawm qhov kev daws teeb meem zoo tshaj plaws. Koj tuaj yeem siv qhov multimeter no thiab xaiv qhov ntau yam uas muab kev daws teeb meem zoo tshaj plaws rau koj nyeem. Nov yog ib qho piv txwv: siv 10V ntau yam los ntsuas 1.3V DC voltage teeb liab, kev nyeem ntawv yog 1.30034V, thiab qhov kev daws teeb meem yog 0.00001V. Hloov qhov ntau mus rau 100V, kev nyeem ntawv yog 1.3004V, thiab qhov kev daws teeb meem yog 0.0001V. Raws li tuaj yeem pom los ntawm qhov piv txwv no, rau qhov ntsuas 1.3V, xaiv 10V ntau yam muab kev daws teeb meem siab dua li 100V ntau.
