Digital multimeters yog cov cuab yeej ntsuas yooj yim. Hauv tsab xov xwm no, tus kws sau ntawv yuav qhia koj yuav ua li cas siv digital multimeter kom raug. Pib los ntawm cov kev ntsuas ntawm digital multimeters xws li voltage, tsis kam, tam sim no, diodes, triodes, thiab MOS field effect raj, 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 ON / OFF hloov mus rau hauv txoj haujlwm ON, xyuas lub roj teeb 9V, yog tias lub roj teeb tsis txaus, nws yuav tsum tau muab tso rau ntawm 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 voj voog sab hauv los ntawm kev puas tsuaj.
⑶ ua ntej qhov kev xeem. Cov kev hloov pauv yuav tsum tau teem rau qhov ntau yam koj xav tau.
