Piv txwv li, tib tus lej 5 thiab ib nrab, suav yog 240000, piv txwv li, 2V iav, xav txog qhov ntau dhau, qhov tseeb, lub iav tuaj yeem ntsuas rau 2.39999. V, uas yog, txhua tus suav suav nrog 0.00001V, uas yog, 10uV, uas yog hais tias, tus lej suav yog tag nrho pes tsawg qhov ntau tuaj yeem muab faib ua? Nws tseem yog 5 thiab ib nrab tus lej. Yog tias nws yog 120000 suav, qhov ntau tseem yog 0 ~ 2.4V. Pom tseeb, txhua feem yog 20uV, uas txhais tau hais tias qhov kev daws teeb meem zoo tuaj yeem ncav cuag 20uV, uas tseem yog 5 thiab ib nrab tus lej. Muaj qhov sib txawv ntawm qhov tshwj xeeb ntawm ob lub multimeters no, yog li cov lej suav ntau dua, qhov tseeb dua.
