Cov txheej txheem ntawm digital multimeter los xyuas seb qhov kev tiv thaiv zoo los yog phem:
1. Kho rau cov ntaub ntawv diode (tseem hu ua cov ntaub ntawv buzzer).
2. Siv ob lub xeem coj ntawm lub multimeter los ntsuas ob tus pins ntawm qhov tsis kam.
3. Tus nqi tso tawm yog ze rau tus nqi nominal ntawm tus resistor, qhia tias tus resistor zoo.
4. Yog hais tias tus nqi tso tawm ib txwm yog "1", nws txhais tau hais tias tus resistor yog qhib sab hauv.
5. Yog hais tias tus nqi tso tawm yog ib txwm "0", nws txhais tau hais tias tus resistor puas lawm (luv luv Circuit Court).
Lus Cim: Yog tias qhov kev tiv thaiv ntawm cov resistor loj heev, qhov ntsuas tus nqi tsis tas yuav tsum muaj tus nqi ntawm cov resistor, yog li yog tias koj xav ntsuas nws qhov tsis kam, koj yuav tsum siv cov iav tiv thaiv.
Digital multimeters yog cov cuab yeej ntsuas yooj yim. Txoj hauv kev yog siv digital multimeter. 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 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 pub tshaj tus nqi qhia, uas yog los tiv thaiv lub voj voog sab hauv los ntawm kev puas tsuaj.
3. Ua ntej kuaj. Cov kev hloov pauv yuav tsum tau teem rau qhov ntau yam koj xav tau.
