LED zaub screensmuaj cov yam ntxwv xws li kev tiv thaiv ib puag ncig, siab ci, siab clarity, thiab kev ntseeg siab.Nrog rau kev nce qib ntawm thev naus laus zis, LED cov ntxaij vab tshaus tau siv dav.Hauv qab no, peb yuav qhia txog cov kev tshuaj xyuas uas siv los kho LED cov ntxaij vab tshaus hluav taws xob, vam tias yuav pab tau rau txhua tus.
01 Short circuit detection method
Teem lub multimeter rau qhovluv luvhom kev kuaj pom (feem ntau nrog lub tswb muaj nuj nqi, yog tias nws yog conductive, nws yuav emit suab beep) kom paub seb puas muaj luv luv Circuit Court.Yog tias pom muaj hluav taws xob luv luv, nws yuav tsum tau daws tam sim ntawd.luv Circuit Court kuj yog qhov feem ntau LED zaub module txhaum.Qee qhov tuaj yeem pom los ntawm kev soj ntsuam IC pins thiab tus pin pins.Kev kuaj xyuas luv luv yuav tsum tau ua thaum lub tshuab hluav taws xob raug kaw kom tsis txhob ua rau lub tshuab hluav taws xob puas.Txoj kev no yog qhov feem ntau siv, yooj yim thiab siv tau zoo.90% ntawm qhov txhaum tuaj yeem kuaj pom thiab txiav txim los ntawm txoj kev no.
02 Resistance detection method
Teem lub multimeter rau qhov kev tiv thaiv ntau yam, sim cov nqi hauv av ntawm qee qhov taw tes ntawm lub rooj tsav xwm ib txwm muaj, thiab tom qab ntawd sim seb puas muaj qhov sib txawv ntawm tib lub ntsiab lus ntawm lwm lub rooj tsav xwm zoo tib yam thiab cov nqi tiv thaiv ib txwm muaj.Yog tias muaj qhov sib txawv, qhov ntau ntawm qhov teeb meem yog txiav txim siab.
03 Voltage detection method
Teem lub multimeter mus rau qhov voltage ntau, ntes cov av voltage ntawm ib qho chaw nyob rau hauv qhov kev xav tias Circuit Court, piv seb nws puas zoo ib yam li tus nqi ib txwm, thiab yooj yim txiav txim siab qhov ntau ntawm qhov teeb meem.
04 Kev ntsuas qhov ntsuas qhov siab
Teem lub multimeter rau lub diode voltage nco nrhiav hom, raws li tag nrho cov ICs yog tsim los ntawm ntau yam yooj yim ib feem, tsuas yog miniaturized.Yog li ntawd, thaum muaj tam sim no dhau los ntawm ib qho ntawm nws cov pins, yuav muaj qhov hluav taws xob poob ntawm tus pins.Feem ntau, qhov hluav taws xob poob ntawm tib tus pins ntawm tib tus qauv ntawm IC zoo ib yam.Nyob ntawm qhov ntsuas hluav taws xob poob ntawm tus pins, nws yuav tsum tau ua haujlwm thaum lub tshuab hluav taws xob raug kaw.
