Qhov tseeb, peb txhua tus paub tias cov khoom siv LED sab hauv tsev tsis hais qhov zoo npaum li cas, muaj kev saib xyuas, nws lub neej ntev ntxiv rau qhov zoo ntawm cov khoom nws tus kheej, kev saib xyuas kuj yog ib qho tseem ceeb hauv tsev LED zaub, zoo li lwm yam. cov khoom, nws tsim nyog muaj teeb meem.Qhov peb tuaj yeem ua tau zoo dua yog nrhiav kom paub txog cov teeb meem ua ntej lawv tuaj thiab ua haujlwm tu ua ntej kom deb li deb tau.Yog li dab tsi yog kev saib xyuas thiab kev tshawb pom ntawm sab hauv LED zaub screen?Yuav ua li cas tus neeg siv yuav ua tau ib txoj hauj lwm zoo ntawm sab hauv LED zaub screen nrhiav kom tau?
1. Nyob sab hauv tsev LED Screen tsis kam kuaj, kev ntsuas kev tiv thaiv rau sab hauv tsev coj zaub, peb yuav tsum xa cov multimeter los tiv thaiv, thawj zaug nrhiav pom lwm daim ntawm lub rooj tsav xwm ib txwm nyob rau hauv av tsis kam ntawm qee qhov taw tes, thiab tom qab ntawd kuaj tib lub ntsiab lus sim lwm daim. ntawm tib lub rooj tsav xwm hauv Circuit Court, yog tias muaj qhov sib txawv nrog kev ua haujlwm ib txwm muaj thiab paub yog tias muaj qhov sib txawv, qhov ntsuas ntawm qhov teeb meem ntawm sab hauv coj zaub, qhov sib txawv yuav yog.
2. sab hauv LED zaub voltage nrhiav kom tau txoj kev: sab hauv LED zaub voltage nrhiav kom tau yog kho lub multimeter rau cov ntaub ntawv voltage, ntes ib tug tsis txaus ntseeg thiab teeb meem Circuit Court ntawm ib tug taw tes rau hauv av voltage, piv nrog rau yav dhau los yog ib txwm, kom nws yuav ua tau. yooj yim los txiav txim qhov teeb meem.
3. sab hauv LED zaub luv Circuit Court nrhiav kom tau txoj kev: sab hauv LED zaub luv Circuit Court nrhiav kom tau txoj kev yog los kho cov multimeter rau luv luv Circuit Court detection thaiv, kom koj yuav ntes tau seb puas muaj ib tug luv luv Circuit Court tshwm sim.Yog tias muaj qhov tshwm sim luv luv, nws yuav tsum tau daws tam sim ntawd.Qhov luv luv Circuit Court tshwm sim ntawm sab hauv LED zaub screen kuj yog qhov feem ntau hauv tsev LED zaub module tsis ua hauj lwm.Ntxiv thiab!Kev kuaj xyuas luv luv yuav tsum tau ua thaum lub tshuab hluav taws xob raug kaw kom tsis txhob muaj kev puas tsuaj rau multimeter.
4. sab hauv tsev coj zaub siab poob kev sim: sab hauv tsev coj zaub siab poob kev sim yog nias lub multimeter hloov mus rau diode nco kev sim, vim hais tias sab hauv tsev coj zaub tag nrho cov IC yog tsim los ntawm ntau chav tsev, yog li thaum nws nyob ntawm tus pin yog energized thaum yuav muaj nyob rau hauv phau ntawv qhia |ko taw poob.Raws li ib txwm muaj, lub siab poob ntawm IC tus pin ntawm tib tus qauv zoo ib yam.
Rau cov saum toj no ob peb sab hauv tsev L ED zaub kev saib xyuas peb tuaj yeem khaws cia rau hauv lub siab, thaum lub sijhawm tshawb pom, kom tsis txhob muaj kev puas tsuaj ntawm peb sab hauv LED zaub, kuj tseem tuaj yeem ua tau zoo heev los txuas ntxiv kev pab cuam lub neej ntawm peb sab hauv LED zaub.Nyob rau hauv txoj kev no, nws tuaj yeem tsis tsuas yog ncua nws lub sijhawm siv, tab sis kuj txuag cov nyiaj siv tsis tsim nyog.
