Teeb lub multimeter rau ntsuas ac lossis dcvoltage raws li xav tau. Tig lub xov tooj mus rau hom kev ua haujlwm (Ω). Nws tuaj yeem faib qhov chaw ntawm lub xov tooj nrog lwm txoj haujlwm. Txuas lub xeem coj mus rau diode tom qab nws tau raug tshem tawm ntawm lub Circuit Court.

Tsuas yog li ntawd, kuv puas tuaj yeem kuaj lub diode hauv Circuit Court?

Qhov zoo ntawm lub davhlau ya nyob twg a diode hu ua theanode, thiab lub davhlau ya nyob twg tsis zoo hu ua cathode. Koj ua tau puas a diode los ntawm tshaj nws qhov ntsuas voltage lossis tam sim no tus nqi. Feem ntau, ua tsis tiav diode yuav cia tam sim no topass nyob rau hauv ob qho tib si kev taw qhia unimpeded. Koj tuaj yeem kuaj lub diode siv ib tug multimeter.

Ib yam li ntawd, koj yuav txheeb xyuas lub diode davhlau ya nyob twg? Qhov yooj yim tshaj plaws txoj kev txheeb xyuas tus cov terminals ntawm a diode yog mus nrhiav ib tug me me dav 'band' nyob ib ncig ntawm lub diode uas koj yuav tau pom ntawm ib diode . Theportion ntawm diode nyob rau sab uas lub cim no cim, yog tus n lub davhlau ya nyob twg hos lwm tus yog li no p lub davhlau ya nyob twg . Lwm txoj kev yog siv lub diode hauv ib qho yooj yim ledcircuit.

Ntxiv mus, koj yuav ua li cas kuaj lub rectifier diode?

Teem lub multimeter rau qhov diode xeem txoj hauj lwm, feem ntau cim nrog a diode cim. Kov cov meterprobes rau txhua qhov kawg ntawm a diode yuav muab peb qhov kev nyeem tau: Qhib Circuit Court (feem ntau qhia los ntawm tus lej 1 ntawm sab laug sab ntawm cov zaub, lossis cov ntawv OL)

Yuav ua li cas txheeb xyuas diode polarity nrog multimeter?

Qee lub sij hawm nws yooj yim tshaj tsuas yog siv a multimeter rau xeem rau polarity . Tig lub multimeter rau diode kev teeb tsa (feem ntau qhia los ntawm a diode cim), thiab kov txhua qhov kev sojntsuam mus rau ib qho ntawm LED terminals. Yog tias LED teeb pom kev, qhov kev sojntsuam zoo yog kov lub anode , thiab qhov kev sojntsuam tsis zoo yog kov lub cathode.
