Digital multimeters yog cov cuab yeej ntsuas yooj yim. Hauv tsab xov xwm no, tus sau yuav qhia koj yuav ua li cas siv digital multimeter kom raug. Pib los ntawm cov txheej txheem ntsuas ntawm digital multimeters xws li voltage, tsis kam, tam sim no, diodes, triodes, thiab MOS field effect tubes, koj tuaj yeem nkag siab zoo dua cov kev ntsuas multimeter.
Ua ntej siv, koj yuav tsum tau nyeem phau ntawv qhia cov lus qhia kom zoo thiab paub txog kev ua haujlwm ntawm lub hwj chim hloov, hloov ntau yam, jack, thiab tshwj xeeb jack.
(1) Muab lub ON / OFF hloov mus rau hauv ON txoj hauj lwm, kos lub 9V roj teeb, yog tias lub roj teeb voltage tsis txaus, nws yuav tsum tau muab tso rau hauv cov zaub, ces lub roj teeb yuav tsum tau hloov. Yog tias cov zaub tsis pom, ua raws cov kauj ruam hauv qab no.
(2) Lub cim ntawm ib sab ntawm qhov ntsuas tus cwj mem qhia tau hais tias qhov input voltage lossis tam sim no yuav tsum tsis txhob tshaj tus nqi qhia, uas yog los tiv thaiv lub hauv paus ntawm kev puas tsuaj.
