Kebul ɗin da ba a gwada shi ba yana nufin ba ku san ko tana aiki ba, nisan da za ta iya tafiya, ko akwai hutu a tsakiya, ko kuma ƙarar siginar tana cikin iyakoki karɓuwa. A cikin injiniyan cabling, gwajin kebul ba 'ƙarin mataki' ba ne - shine layin ƙarshe na tsaro don ingancin isarwa.
Wani kuskuren da aka saba shine cewa sabbin igiyoyi an gwada masana'anta kuma basa buƙatar ƙarin gwaji. A zahiri, igiyoyi na iya lalacewa yayin jigilar kaya, ajiya, shigarwa, da ƙarewa - radius mai wuce gona da iri, jan ƙarfi, gogewa daga gefuna masu kaifi, oxidation a masu haɗin kai - duk waɗannan na iya yin shuru suna lalata aikin kebul. A lokacin da mai amfani ya ba da rahoton 'cibiyar sadarwa ta ci gaba da faduwa' ko kuma 'wannan hanyar ba ta da iko,' tushen dalilin yakan yi wahala a gano asalinsa.
Gwajin ci gaba shine abu mafi mahimmanci a gwajin kebul kuma mataki na wajibi bayan kowane ƙarewar na USB. Ka'idar mai sauƙi ce: allurar siginar lantarki a ƙarshen kebul ɗin kuma gano shi a ɗayan. Idan ba a karɓa ba, akwai hutu a tsakiya.
Amma gwajin ci gaba yana da sauƙin watsi da shi - mutane da yawa suna tunanin 'muddin ya yi, yana da kyau'. A zahiri, gwajin ci gaba shine kawai Layer na farko na dubawa. Kebul ɗin da ke gudanarwa maiyuwa ba zai iya watsa bayanai a ƙayyadaddun ƙimar da aka ƙera ba.

Wannan shine dalilin da ya sa ake buƙatar ƙarin gwaji bayan tabbatar da ci gaba.
Ma'aunin tsayin kebul yayi kama da lamba ɗaya, amma yana ɗaukar bayanai fiye da yadda kuke zato. Na farko, tsayin bayanai yana da alaƙa kai tsaye da lissafin kayan aiki - sanin adadin mita nawa aka shigar a zahiri yana ba ku damar ƙididdige amfani da kebul daidai kuma ku guje wa sayayya ko ƙasa da siyayya.
