Yadda Ake Faɗa Idan Kebul ɗin Coax Yayi Kuskure (Jagorar Hanyoyi 2)
Abubuwa
A cikin wannan labarin, zan koya muku yadda ake gane mummunan kebul na coax a cikin 'yan mintuna kaɗan.
A matsayin gogaggen jack-of-all-ciniki, Ina amfani da dabaru da yawa don duba yanayin igiyoyin coax. Zan koya muku mafi kyau daga wannan jagorar. Lallatattun igiyoyi na coaxial sun zo da matsaloli da yawa, gami da amma ba'a iyakance ga rufaffen sigina ko mara kyau na intanet ba. Gano tushen dalilin yana da mahimmanci, ba kawai zato don yanke shawara ba.
Gabaɗaya, kuna buƙatar bi ƴan matakai masu sauƙi don gano idan kebul na coax yana da kyau:
- Toshe na'urar gwaji ta DSS01 coax a cikin soket ɗin coax kuma danna maɓallin don gwada shi.
- Yi gwajin ci gaba tare da multimeter na lantarki.
- Hakanan zaka iya bincika ƙarfin ƙarfi, juriya, da abin ƙyama tare da multimeter na lantarki.
Zan yi muku karin bayani a kasa.
Yadda Ake Gane Laifin Coax Cable
Yana da matukar mahimmanci don tabbatar da yanayin kebul ɗin ku na coaxial. Wannan zai taimaka maka gano ainihin matsalar kuma ba zato ba. Kuna iya amfani da hanyoyi da yawa don bincika idan kebul na coax ɗinku yana da kyau ko mara kyau. Zan yi bayani dalla-dalla game da wasu fasahohin.
Hanyar 1: Amfani da multimeter
Kuna iya amfani da multimeter don bincika idan kebul na coax ɗinku mara kyau.
Multimeter yana gwada ƙarfin sassa daban-daban na na'urar lantarki ta hanyar ƙididdiga masu yawa.
Yi gwaje-gwaje masu zuwa akan kebul na coax:
Gwajin ci gaba
Matakai masu zuwa zasu taimake ku:
Mataki 1: Sanya multimeter
Saka jagorar binciken ja a cikin jack tare da V kusa da shi kuma baƙar fata ta jagoranci cikin jack ɗin COM.
Sannan saita multimeter zuwa ƙimar ma'aunin "Ohm" ta hanyar jujjuya bugun bugun kira. A ƙarshe, ping da wayoyi masu bincike; idan multimeter yayi ƙara, akwai ci gaba tsakanin binciken. Yanzu bari mu fara gwada kebul na coaxial.
Mataki 2: Duba masu haɗin haɗin
Kebul na Coaxial ba shi da polarity.
Taɓa wayoyi masu bincike akan masu haɗin kebul na coaxial guda biyu. Idan multimeter yayi ƙara kuma ya karanta ƙasa da 1 ohm, to akwai ci gaba a cikin kebul ɗin coax ɗin ku. Idan karatun ya wuce ohm ɗaya, masu haɗin ku sun yi kuskure.
Mataki na 3: Duba wayoyi a cikin mahaɗin.
Taɓa fil a cikin mahaɗin biyu kuma. Duk wani karatu da ke ƙasa ohm ɗaya yana nufin coax ɗin ku yana da kyau.
Gwajin juriya
Anan, multimeter na lantarki zai gwada ƙarfin lantarki na garkuwar kebul na coaxial da sauran abubuwan haɗin kebul. Nunin zai nuna martani/karantawa a HMS (hectometers).
Mataki 1. Saita multimeter ku zuwa yanayin juriya
Mataki 2. Saka 50 ohm dummy lodi a cikin jack ɗaya. Sannan a taɓa gubar guda ɗaya na binciken zuwa saman ɗayan haɗin kuma ɗayan jagora zuwa cikin kwas ɗin guda ɗaya - babu nauyi mai nauyi.
Mataki 3. Kwatanta sakamakon juriyar ku tare da rashin ƙarfi na kebul na coax na ku.
Binciken iya aiki
Bugu da ƙari, yi amfani da na'urar multimeter na lantarki don bincika ƙarfin jaket da jagoran na USB na coax. Lissafi za su kasance a cikin picofarads (pf).
Tsarin aiki: Tare da multimeter da aka canza zuwa yanayin auna juriya, taɓa jagorar a kan iyakar biyu na kebul na coaxial kuma lura da karatun, wanda zai zama ƙananan - a cikin picometers.
Gwajin inductance
Kuna iya amfani da multimeter na lantarki don bincika inductance na garkuwa da layin coaxial na USB. Lokacin gwada inductance, nanohenry (NH) da ohm (ohm) mafita an tattauna.
Alamomin igiyar coax ta lalace
Rustic Connectors – Idan tsatsa ta bayyana a ƙarshen kebul ɗin coax ɗin ku, kebul ɗin coax yana da lahani.
Abubuwan da suka ɓace suna nuna matsala tare da kebul na coax.
Koren launi na masu haɗin kebul na coaxial kuma yana nuna lalacewa.
Rarrauna masu haɗawa – Idan ka karkatar da masu haɗin kai akan kebul na coaxial kuma ka ji kamar suna kwance, sun lalace.
fallasa wayoyi – Idan igiyoyin da ke cikin kebul na coax suna bayyane, ya lalace.
Rumbun filastik da aka lalace (wanda ake kira garkuwar roba) – Idan garkuwar roba ta lalace, kebul ɗin coax ɗin ku na iya zama mara lahani.
Don haka, idan kun lura da ɗaya daga cikin waɗannan alamun, yi amfani da multimeter na lantarki don tabbatarwa.
Note: Hanyar ganowa ta farko don gwada coax shine don ganin ko sun riga sun gaza.
Kamfanoni iri-iri ne ke yin kebul na Coaxial, don haka ingancin su ya bambanta sosai.
Hanyar 2: Amfani da DSS01 Coax Cable Tester
Ina ba da shawarar amfani da DSS01 Coax Cable Tester don bincika matsaloli tare da kebul ɗin coax ɗin ku. Tare da wannan kayan aiki, kuna guje wa siye ko amfani da waɗannan abubuwan:
- liyafar siginar matsala
- Matsalar watsa siginar matsala
- Ba a buƙatar multimeter
- Coax Cable Tracking
- Gwajin ci gaba - akan kebul na coaxial.
- Duk abin da kuke buƙata shine DSS01 Coax Cable Tester!
Yadda ake amfani da DSS01 coaxial na USB tester
Bi waɗannan matakai masu sauƙi don gwada kebul ɗin coax ɗinku tare da mai gwada DSS01:
Mataki 1. Haɗa DSS01 Coax Cable Tester zuwa soket na coax.
Mataki 2. Danna maɓallin Gwaji. Sakamakon zai bayyana a cikin 'yan daƙiƙa kaɗan.
DSS01 coaxial na USB tester yana adana lokaci da kuɗi. Duk abin da kuke buƙatar sani shine yadda ake haɗa soket ɗin coaxial da maɓallin gwaji - yana da sauƙin amfani.
Matsalolin gama gari da ke shafar igiyoyin Coaxial
Na zaɓi manyan dalilai guda huɗu na rashin nasarar kebul na coaxial. Kauce musu don tabbatar da tsawon rayuwa da aminci gaba ɗaya na igiyoyin coax ɗin ku.
Lalacewar zafi
Matsakaicin narkewar igiyoyin coaxial shine 150°F. Wannan wuri ne mai ƙarancin narkewa. Don haka, igiyoyin coaxial suna da rauni ga yanayin zafi. (1)
alamu: Don gujewa lalacewar zafi ga kebul na coaxial, kiyaye shi daga tushen zafi. Idan ba haka ba, garkuwar roba na iya narkewa, tana tura abubuwan da ke cikin kebul ɗin daga wurin.
Lalacewar ruwa
Yawancin na'urorin lantarki suna da rauni ga ruwa. Coaxial igiyoyi ba togiya. Wayoyin lantarki da abubuwan haɗin gwiwa na iya gazawa idan an fallasa su da ruwa. Don haka, kiyaye kebul na coaxial daga ruwa.
murdiya ta jiki
Garkuwar kebul na coaxial mai rauni ne. Kus ɗin kebul ɗin na iya karyewa idan an jefe shi, an sarrafa shi, ko lankwasa da rashin kulawa. Koyaushe hanyar igiyoyi kai tsaye gaba. Ƙarƙashin lanƙwasa ko kink na iya haifar da innards na kebul na coax (ko abubuwan ciki) su faɗi.
Lalacewar mahaɗa
Lalacewar haši na iya haifar da gazawar kebul na coaxial.
An sanye da igiyoyin igiyoyi tare da masu haɗawa a ƙarshen duka. Masu haɗin kai suna canja wurin bayanai daga wannan tushe zuwa wani. Don haka, canza ko wanne daga cikin masu haɗin biyu yana lalata aikin kebul na coaxial. Abin farin ciki, idan kun sami matsaloli, za ku iya maye gurbin masu haɗawa maimakon siyan sabuwar kebul. Kuma, ba shakka, wannan shine babban dalilin gazawar igiyoyin coaxial. (2)
