Network cable xeem

Tom qab ob qho tag nrho ntawm lub taub hau crystal ua tiav, qhov kev xeem tuaj yeem nqa nrog lub network kab. Yog tias tag nrho 8 qhov ntsuas ntawm tus tester yog ntsuab flashing, kev tsim cov kab hauv lub network muaj kev vam meej. If there is any a lamp for the red or yellow light, all that exist cut-off or poor contact phenomenon, the best first ends of crystal head again with the cable clamp pressure, measured again, if the fault is still, to check whether the conductor on both ends of the order, if not the same, with the cut end to press the other end of the wire order making crystal head. Yog tias cov xov hlau nyob hauv tib qho kev txiav txim, tab sis tus tester tseem qhia cov teeb liab lossis daj tom qab rov ua dua tshiab, nws qhia tias yuav tsum muaj qhov tsis zoo ntawm cov xov hlau. Nyob rau lub sijhawm no, tsis muaj lwm txoj kev, yog li peb yuav tsum txiav ib qho kawg thiab ua kom lub taub hau crystal dua raws li lwm qhov kawg ntawm cov hlau loj. Tom qab ntawd peb tuaj yeem sim ntawd. Kom txog rau thaum tag nrho cov kev ntsuam xyuas yog ntsuab, qhov ntsuas flashes. Rau cov txheej txheem sib txawv ntau lawm, qhov kev txiav txim ntawm qhov teeb pom kev ntawm lub tester tseem txawv. Yog hais tias lub teeb ntawm tus tes taw yog nyob ntawm txoj kab ncaj ncaj, nws yuav tsum nyob hauv kab ntawv. Yog hais tias nws yog nyob rau ntawm tus ntoo khaub lig kab, kev txiav txim ntawm kev ntsais nyem ntawm ntu ntawm tus tester yuav tsum yog 3, 6, 1, 5, 5, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7 thiab 8.
