Digital multimeter diode iav thiab diode ntsuas txoj kev

 

Diode iav yog qhov siv ntau zaus ntawm kev siv lub iav, feem ntau hauv cov ntsuas digital muaj cov iav no, lub logo yog lub cim diode, tej zaum yuav muaj qhov "cim" zoo sib xws nyob ib ncig ntawm lub cim, koj tuaj yeem xa mus rau daim duab saum toj no ntawm tus sawv cev. .


Tig lub multimeter rau lub iav no, saib yog tias cov zaub qhia cov cim "cim" saum toj no, qhov tseeb, qhov no yog cov ntaub ntawv buzzer, yog tias tus cwj mem liab thiab dub luv luv, koj yuav hnov ​​​​lub suab buzzer, nrog lub iav no tuaj yeem ntsuas qhov ntsuas qhov ntsuas kub. tus neeg xyuas pib rau thiab tawm, tab sis hnub no peb tab tom tham txog lwm tus, nias lub pob hloov ntawm lub rooj digital! , koj tuaj yeem pom lub cim diode pom ntawm cov zaub.


Raws li tus cwj mem liab ntawm lub ntsuas hluav taws xob txuas nrog lub davhlau ya nyob twg zoo ntawm cov khoom siv hluav taws xob sab hauv, tus cwj mem dub txuas nrog lub tshuab hluav taws xob tsis zoo ntawm lub tshuab hluav taws xob sab hauv, yog li cov ntsuas digital ntsuas lub diode thaum tus cwj mem liab ntawm lub diode lub davhlau ya nyob twg zoo. , tus cwj mem dub txuas nrog qhov tsis zoo ntawm lub diode, cov zaub ib txwm yuav qhia cov diode qhov zoo conduction voltage poob, piv txwv li, cov duab hauv qab no ntawm diode conduction voltage poob ntawm 0.607 volts.


Rau ib txwm diode tuaj yeem ntsuas ntawm qhov ntsuas hluav taws xob poob, tab sis lub diode rov qab (tus cwj mem liab txuas nrog lub diode tsis zoo, tus cwj mem dub txuas nrog lub diode zoo) tsis ntsuas qhov txiaj ntsig, yog li txoj kev no tuaj yeem txiav txim siab lub diode zoo lossis phem, koj tuaj yeem xa mus rau cov txiaj ntsig ntawm kev ntsuas hauv daim duab hauv qab no.


Kev ntsuas ntawm diodes yog rau cov raj rectifier zoo tib yam li piv txwv, qhov tseeb, rau lwm hom diodes kuj tseem siv tau rau hauv txoj kev no, piv txwv li, nrog cov iav no kuj tuaj yeem ntsuas tawm ntawm lub teeb LED (lub teeb-emitting diodes) conduction voltage poob.
