LED kuratidza skrinivane hunhu hwakadai sekuchengetedzwa kwezvakatipoteredza, kupenya kwepamusoro, kujeka kwepamusoro, uye kuvimbika kwepamusoro.Nekufambira mberi kwe tekinoroji, ma LED ekuratidzira skrini akashandiswa zvakanyanya.Pazasi, isu tichasuma nzira dzinowanzoshandiswa dzekuongorora dzekugadzirisa LED dzemagetsi kuratidza skrini, tichitarisira kubatsira kune wese.
01 Short circuit yekuona nzira
Isa iyo multimeter kune iyoshort circuityekuona mode (kazhinji ine alarm function, kana iri conductive, inoburitsa beep sound) kuona kana paine pfupi pfupi.Kana dunhu rakapfupika rawanikwa, rinofanira kugadziriswa nekukurumidza.Short circuit zvakare ndiyo yakajairika LED kuratidza module kukanganisa.Mamwe anogona kuwanikwa nekutarisa maIC mapini nemapini.Kuonekwa kwedunhu pfupi kunofanirwa kuitwa kana dunhu radzimwa kudzivirira kukuvadza multimeter.Iyi nzira ndiyo inonyanya kushandiswa, iri nyore uye inoshanda.90% yezvikanganiso zvinogona kuonekwa uye kutongwa kuburikidza nenzira iyi.
02 Resistance yekuona nzira
Isa iyo multimeter kune yekupikisa renji, edza kukosha kwepasi kupokana pane imwe nzvimbo pane yakajairwa redunhu bhodhi, uye woyedza kana paine musiyano pakati peiyo imwe pfungwa pane imwe yakafanana dhizaini bhodhi uye yakajairika kuramba kukosha.Kana pane musiyano, huwandu hwedambudziko hunotarwa.
03 Voltage yekuona nzira
Seta iyo multimeter kune voltage renji, tarisa pasi voltage pane imwe nzvimbo munharaunda inofungidzirwa, enzanisa kana yakafanana neyakajairika kukosha, uye nyore kuona huwandu hwedambudziko.
04 Kudzvanya kudonha kwekuona nzira
Seta iyo multimeter kune diode voltage kudonhedza yekuona modhi, sezvo ese maICs anoumbwa akawanda ekutanga ega ega zvikamu, chete miniaturized.Naizvozvo, kana paine ikozvino inopfuura neimwe yepini yayo, pachave nekudonha kwevoltage pamapini.Kazhinji, kudonha kwemagetsi pamapini akafanana eiyo modhi yeIC yakafanana.Zvichienderana nehuwandu hwekudonha kwevoltage pamapini, zvinodikanwa kushanda kana dunhu radzimwa.
