Coax Tracing (3 Txoj Kev rau 3 Teeb Meem)
Txheem
Hauv tsab xov xwm no, kuv yuav qhia qee txoj hauv kev uas kuv tau kawm los taug qab coax cables yooj yim thiab ua tau zoo.
Raws li ib tus kws paub txog hluav taws xob thiab jack-of-tag nrho-kev lag luam, kuv yuav qhia koj ntau yam kev daws teeb meem los pab ua kom cov txheej txheem yooj yim dua. Muaj peev xwm taug koj cov coaxial cables kom raug txuag koj cov teeb meem ntawm nkim sij hawm daws teeb meem ntau yam nrog koj cov cables.
Raws li txoj cai dav dav, ua raws li cov kauj ruam yooj yim no rau txoj kev coax cable:
- Tau cov cuab yeej taug qab - Cov khoom siv tshuaj ntsuam xyuas, toner, cable tester thiab colour daim kab xev
- Txuas lub connector rau lub transmitter.
- Siv tus hais lus module, xyuas txhua lub cable.
- Thaum koj txuas lub coaxial cable kom raug, koj yuav hnov ib lub suab nrov.
Kuv mam li mus rau hauv ntau yam hauv qab no.
Cov cuab yeej taug qab
Ua ntej, npaj cov cuab yeej tsim nyog ua ntej pib txheej txheem tracing. Ib coaxial cable tracer feem ntau yog ib qho khoom me me uas muaj ntau yam haujlwm; qee cov qauv tuaj yeem tso saib ntau qhov chaw thiab muab cov ntaub ntawv tseem ceeb. Cov cuab yeej no yuav muaj ntau lub npe sib txawv.
Chav ntsuas thiab toner xav tau rau cable routing. Lub cable nws tus kheej txiav txim siab cov cuab yeej tsim nyog.
Yog tias koj muaj ntau coax cables los taug qab thiab tsis xav kom ploj, xav siv daim kab xev xim.
Ntau yam kev daws teeb meem cable tracing muaj nyob ntawm tus nqi tsim nyog. Cov qauv sib txawv yuav suav nrog cov khoom siv thiab cov yam ntxwv ntxiv uas ua rau tag nrho cov txheej txheem yooj yim dua thiab sai dua.
1. Cov kab ntau lawm
Yog tias koj muaj ntau lub cables txuas nrog cov khoom siv sib txawv thiab khiav hauv ntau qhov chaw thoob plaws hauv koj lub tsev, koj yuav tsum siv lub ntsuas hluav taws xob los txiav txim seb qhov coax mus qhov twg. Cov khoom siv no suav nrog "xa" feature uas xa cov teeb liab tshwj xeeb hla lub coax cable. Cov txheej txheem yog yooj yim:
kauj ruam 1. Txuas lub connector rau lub transmitter.
kauj ruam 2. Siv tus hais lus module, xyuas txhua tus coax cable.
Koj yuav hnov ib lub suab nrov thaum lub cable raug txuas. Yog tag nrho.
2. Thaum kawg ntawm lub cable muaj
Yog tias koj muaj ntau cov cables uas xa cov teeb liab mus rau ntau yam khoom siv sib txawv thiab koj yuav tsum nrhiav qhov zoo, koj tuaj yeem siv cov txheej txheem yooj yim. Hauv qhov no, koj xav tau ib qho multimeter.:
Kauj ruam 1: Nruab lub multimeter
Txhawm rau pib, hloov lub multimeter mus rau hom txuas ntxiv los ntawm tig lub pob qhov rooj xaiv mus rau txoj haujlwm "ohm" - txhawm rau ntsuas qhov tsis kam. Tom qab ntawd nruab qhov liab thiab dub multimeter coj mus rau "V" thiab "COM" connectors.
Kauj Ruam 2. Tshawb xyuas cov xov hlau nrog cov ntsuas ntsuas ntau.
Tom qab ntawd kov cov hlau lead liab rau ntawm tus neeg xyuas pib sab hauv thiab cov hlau lead dub rau ntawm qhov txuas sab nraud ntawm lub coaxial cable kom txog thaum koj hnov ib lub suab nrov txuas ntxiv uas qhia txog kev sib txuas ntawm ob lub xov hlau.
Lus qhiaA: Yog tias tsis muaj ib txoj hauv kev no ua haujlwm rau koj, lossis yog tias koj pom tias nws nyuaj los qhia seb lub xov tooj twg yog qhov twg, koj tuaj yeem sim ua qhov pom ntawm lub cable.
3. Ntau cov cables - yuav ua li cas?
Tracing coax cables tuaj yeem ua kom yuam kev, tshwj xeeb tshaj yog tias koj muaj ntau cov cables khiav ntawm phab ntsa lossis qab nthab, tab sis nws yeej ua tau:
kauj ruam 1. Pib los ntawm kev nrhiav pom cov cim pom tseeb ntawm qhov chaw uas lub cable yuav khiav, xws li nyob rau hauv baseboards lossis moldings.
kauj ruam 2. Thaum koj tau txiav txim siab qhov chaw dav dav ntawm lub cable, pib maj mam tapping rau ntawm phab ntsa lossis qab nthab vuas kom txog thaum koj hnov cov suab nrov - qhov no feem ntau qhia tau tias muaj qee yam tom qab qhov chaw no (xws li thaiv!).
Txawm li cas los xij, ceev faj, kev quab yuam ntau dhau tuaj yeem ua rau cov phab ntsa lossis qab nthab!

Yuav ua li cas nrhiav tau coaxial cable nyob rau hauv phab ntsa?
Muaj ob peb yam koj tuaj yeem ua tau yog tias koj tab tom nrhiav coaxial cable hauv koj phab ntsa:
kauj ruam 1. Sim xyuas seb qhov twg cable nkag mus rau koj lub tsev. Qhov no feem ntau yog nyob ze ntawm lub TV lossis qhov chaw uas lub tuam txhab cable txoj kab nkag mus rau hauv koj lub tsev.
kauj ruam 2. Thaum koj tau txiav txim siab tag nrho cheeb tsam, siv tus ntsia thawv nrhiav kom pom cov ntsia hlau lossis cov ntsia hlau hauv phab ntsa uas tuaj yeem tuav cov coax hauv qhov chaw. Yog tias koj tsis tuaj yeem pom dab tsi, sim nrhiav lub coax cable tom qab phab ntsa ntub dej nrog lub teeb nyem.
Yuav ua li cas mus nrhiav tau ib tug zais coaxial cable?
Coaxial cable feem ntau muab zais hauv qab phab ntsa, hauv qab hauv pem teb, lossis saum qab nthab. Pib koj txoj kev tshawb nrhiav rau qhov zais coax cable los ntawm kev nrhiav cov xov hlau uas raug. Tom qab ntawd siv tus finder los nrhiav cov ncej hauv cov phab ntsa thiab kos lawv txoj haujlwm nrog daim kab xev.
Thaum koj pom cov studs, nrhiav qhov sib txawv ntawm lawv qhov twg cov coax cable yuav muab zais. Thaum kawg, nrhiav cov cables uas yuav khiav los ntawm cov khoob no nrog lub teeb nyem.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Yuav ua li cas txheeb xyuas lub teeb liab ntawm coaxial cable nrog multimeter
- Coaxial teeb liab tester
- Yuav ua li cas qhia yog tias coax cable tsis zoo
