Yuav Ua Li Cas Txheeb Xyuas Qhov Teeb Meem ntawm Coax Cable (6 Kauj Ruam)

Hauv tsab xov xwm no, kuv yuav qhia koj yuav ua li cas txhawm rau txheeb xyuas cov teeb liab hauv coaxial cables.

Hauv kuv txoj haujlwm, kuv yuav tsum nquag xyuas seb lub teeb liab coax puas ua haujlwm zoo lossis tsis ua kom muaj kev sib txuas zoo hauv internet thiab kev sib txuas. Thaum lub coaxial cable hnav tawm, kev ua haujlwm ntawm ob lub TV thiab lub tshuab computer txo qis, uas tuaj yeem ua rau lawv tsis ua haujlwm.

Feem ntau, nws tsis yooj yim rau kev kuaj xyuas lub teeb liab ntawm coaxial cable. Ua raws li cov kauj ruam no:

• Tshawb xyuas theem teeb liab ntawm qhov chaw
• Daim ntawv ceeb toom lub zog ntawm thawj lub teeb liab raws li lub zog tseem ceeb ntawm lub teeb liab
• Reconnect tus thawj cable rau lub thawv cable
• Txuas cable rau lub teeb liab ntsuas
• Them mloog mus rau tus nqi ntawm lub teeb liab theem ntawm lub teeb liab qhia.
• Rov ua cov kauj ruam 2 txog 5 rau txhua qhov ntev ntawm coax cable ntawm koj lub network.

Kuv yuav tshawb nrhiav ntxiv hauv qab no.

Coaxial Cable Test

Cov kauj ruam ntxaws ntxaws no yuav pab koj tshawb xyuas lub teeb liab lub zog ntawm koj lub coax cable.

Kauj Ruam 1: Qhov Chaw Theem

Txheeb xyuas qhov theem teeb liab.

Taug qab koj cov kab ke kab ke mus rau qhov chaw uas nws txuas rau koj lub network hauv zos. Tshem tawm cov coax cable los ntawm lub network sab ntawm lub thawv thiab txuas mus rau lub teeb liab cable ntsuas lossis coax tester.

Kauj Ruam 2. Kos lub zog ntawm thawj lub teeb liab raws li lub hauv paus teeb liab lub zog.

Sau cov theem ntawm qhov chaw teeb liab raws li theem pib.

Koj lub meter qhia cov teeb liab theem hauv decibel millivolts (dbmV). Cov ntsuas hluav taws xob tuaj yeem hloov pauv ntawm qhov kev txiav txim ntawm qhov loj, tshaj tawm ntau pua lossis ntau txhiab dBmV ntawm tib theem tso zis, yog li them sai sai rau qhov ntsuas ntsuas ntsuas.

Kauj ruam 3: Reconnect tus thawj cable rau lub thawv cable.

Reconnect tus thawj cable rau lub thawv cable thiab ua raws li nws mus rau thawj kawg kawg. Qhov no tuaj yeem tshwm sim ntawm kev sib tshuam, kev sib tshuam, TV lossis modem.

Kauj ruam 4 Txuas lub cable mus rau lub teeb liab ntsuas los yog coaxial cable tester.

Tshem tawm lub cable los ntawm lub davhlau ya nyob twg nws txuas nrog thiab txuas mus rau lub teeb liab lub zog ntsuas.

Kauj Ruam 5: Ua tib zoo mloog rau lub teeb liab muaj zog tus nqi

Ntsuas lub teeb liab theem.

Txawm hais tias me ntsis teeb liab degradation yuav tsum nyob ntawm cable, koj lub teeb liab lub zog yuav tsum sib piv rau koj cov kev nyeem hauv qab. Txwv tsis pub, lub coaxial cable yuav tsum tau hloov.

Lub teeb liab txhais tau hais tias lub cable yog ok.

Kauj ruam 6. Rov ua kauj ruam ob txog tsib rau txhua qhov ntev ntawm coax cable ntawm koj lub network.

Rov ua cov kauj ruam 2 txog 5 rau txhua qhov ntev ntawm coaxial cable ntawm koj lub network kom cais cov cable txuas ntxiv.

Lub teeb liab lub zog degrades nrog txhua lub hop thiab cable ntev, tab sis ib qho tseem ceeb degradation qhia tau hais tias ib tug splitter los yog cable tsis ua hauj lwm. Yuav kom tswj tau cov teeb liab kev ncaj ncees, cov faulty cables thiab splitters yuav tsum tau hloov. (1)

Qhov zoo tshaj plaws Trick rau Tracing thiab Test Coax Cable

Rau kev taug qab thiab kuaj cov coaxial cable, koj tuaj yeem siv cov cuab yeej tsim nyog thiab tus qauv uas yuav ua kom yooj yim dua thiab ua kom koj txoj haujlwm. Kuv tau suav qee cov ntaub ntawv hais txog qhov zoo tshaj plaws coax cable tester thiab explorer kom ua tau yooj yim dua.

• Nws tuaj yeem tshawb xyuas qhov txuas ntxiv ntawm coaxial cable thiab tso saib cov cable hauv plaub qhov chaw sib txawv tib lub sijhawm.
• Nws los nrog cov xim-coded chaw taws teeb tswj kom yooj yim txheeb xyuas.
• LED cov cim qhia tias muaj qhov luv luv, tawg lossis kev noj qab haus huv ntawm coaxial cable.
• Nws muaj lub teeb yuag thiab compact tsim uas haum yooj yim hauv koj lub hnab ris.
• Tus kov yooj yim ua kom yooj yim nqa thiab ua haujlwm.

Summing txog

Kuv vam tias phau ntawv qhia no yuav pab koj saib xyuas thiab ntsuas lub teeb liab zoo ntawm koj lub coax cable kom pom kev siv internet ceev thiab lub zog. Cov txheej txheem yog qhov yooj yim heev thiab tsis tas yuav tsum muaj tus kws tshaj lij los ua nws; cia li ua raws li cov kauj ruam kuv tau muab. (2)
