Txhua yam koj xav tau kuaj LED teeb yog digital multimeter nrog teeb tsa diode. Ua ntej, txuas cov xim dub thiab liab xeem coj mus rau qhov hluav taws xob nyob rau pem hauv ntej ntawm lub multimeter. Thaum cov coj tau txuas nrog, hloov lub xov tooj ntawm sab xub ntiag ntawm lub xov tooj cua raws lub moos kom mus txog qhov teeb tsa diode.
Qhov tseeb, koj puas tuaj yeem kuaj lub teeb LED kom txuas ntxiv?
Txawm hais tias koj ua tau yooj yim test ib LED los ntawm kev txuas nws mus rau hauv Circuit Court thiab pom yog nws yuav kaj nce, koj ua tau kuj siv lub ntsuas hluav taws xob nrog lub diode xeem muaj nuj nqi rau test ib LED thiab tshawb pom ob peb yam ntxiv txog nws ib yam.
Qhov thib ob, koj yuav kho qhov muag teeb LED li cas? Kho Tuag Tuag COB LED Lub Teeb
- Kauj Ruam 1: Qhia thiab Tom Qab.
- Kauj Ruam 2: Tshem tawm thiab Txheeb Xyuas Cov Khoom Siv Hluav Taws Xob.
- Kauj ruam 3: Nrhiav qhov phem LED.
- Kauj Ruam 4: Tshem Tawm Cov Qub Qub Qub.
- Kauj Ruam 5: Saib dua LED tshiab los Hloov Qhov Tsis Zoo.
- Kauj ruam 6: Nruab lub LED Tshiab nyob rau hauv qhov chaw ntawm qhov phem.
- Kauj Ruam 7: Rov Qab Ua Ke !!!
Hauv qhov no, puas yog qhov muag teev qhov muag ua ntej lawv hlawv tawm?
LEDs tsuas yog muab lub teeb thaum twg hluav taws xob hluav taws xob khiav los ntawm lawv. Yog tias qhov voltage no tsis tas li, flickering yuav tshwm sim. Qhov no tsuas cuam tshuam LED qhov muag teev vim lwm tus nyiam halogens thiab incandescent tuav kom muaj cua sov txaus los npog luv luv hauv qhov hluav taws xob. LEDs tsis txhob.
Kuv yuav ntsuas kuv li SMD LED li cas?
SMD diodes muaj ntau ntawm cov cim anode/cathode. Qee lub sij hawm nws yooj yim tshaj plaws tsuas yog siv lub multimeter rau xeem rau polarity Tig lub multimeter mus rau qhov chaw diode (feem ntau qhia los ntawm lub cim diode), thiab kov txhua qhov kev sojntsuam mus rau ib qho ntawm LED cov dav hlau

Tig tus yuam sij rau lub 'On,' lossis thib ob, tso rau ntawm qhov hluav taws kub, tab sis tsis txhob tig lub cav. Nias thiab tuav khawm rov pib dua ntawm lub ntsuas vaj huam sib luag kom txog thaum TPMS lub teeb pib ntsais muag thiab tom qab ntawd tawm mus
Koj yuav ntsuas tus ntsuas qhov ntsuas qhov nrawm li cas?
Kuaj TPS siv lub tshuab ntsuas digital. Xyuas kom tseeb tias nws tseem ua haujlwm thiab, yog tias tsim nyog, pom qhov muag thiab sim cov xov hlau thiab cov khoom txuas. Yog tias lub ntsuas ntsuas ntsuas OK, lwv cov cai. Yog tias nws rov qab los lossis koj pom qhov teeb meem kev ua tau zoo
Koj yuav hloov pauv tus ntsuas ntsuas ntsuas kub los ntawm Celsius mus rau Fahrenheit li cas?
Txhawm rau hloov ntawm Celsius thiab Fahrenheit ua raws li cov lus qhia no: Xyuas kom lub ntsuas kub tsis raug. Nias thiab tuav Pob Ntseg pob ntseg rau 10 vib nas this kom txog thaum cov duab pom " - - -˚C" lossis. Tso pob ntseg pob ntseg. Nias pob pob ntseg ib zaug kom hloov ntawm ˚C mus rau ˚F lossis los ntawm ˚F mus rau ˚C
