(2) Duba ko hasken alamar wutar da ke cikin mai sarrafawa yana kunne, idan yana a kunne, duba ko kebul ɗin nuni bai yi daidai ba; idan haske mai nuna alamar ciki yana kashewa (ciki yana duhu), gyara shi gwargwadon hanyoyin da ke tafe.

(3) Duba ko akwai ɗan gajeren kewaye a cikin mai sarrafa. Cire haɗin kebul na tashar jiragen ruwa a bayan mai sarrafawa, yi amfani da mita don gwada ko akwai ɗan gajeren zango tsakanin fil 6 da fil 9 na tashar serial. Tabbatar cewa babu gajeren gajeren zango na ciki (wato, babu gajeriyar madaidaiciya tsakanin fil 6 da fil 9 na tashar serial a bayan mai sarrafawa. Abin mamaki na gajeren zango).

(4) Duba ko wutar lantarki mai canzawa tana da fitowar DC 5V. Cire haɗin kebul na tashar jiragen ruwa a bayan mai sarrafawa, kunna wutar, kuma yi amfani da mita don gwada ko wutar lantarki mai sauyawa tana da fitowar DC 5V, ko a gani a duba ko alamar mai nuna alama kusa da wutan lantarki mai sauyawa yana kunne. Tabbatar cewa ƙarfin fitarwa na wutan lantarki na canzawa al’ada ne.

(5) Duba ko da’irar samar da wutar lantarki ta mai sarrafawa ta karye (gwajin kayan aiki).

(6) Bincika ko mai haɗa haɗin ciki na mai sarrafawa a kashe yake ko sako -sako.

(7) Cikakken gazawar kewaye, tuntuɓi mai ƙira don cire ko maye gurbinsa.

(2) Nuna matsalolin kebul ko matsalolin nuni. Tuntuɓi masana’anta don maye gurbin.

G: Mai sarrafawa yana sake farawa akai -akai: bincika ko fitowar 5V DC na wutar lantarki mai sauyawa yana da tsayayye (canji a cikin ± 0.2V). Gabaɗaya, yana haifar da babban tsalle tsalle na fitowar ƙarfin wutan lantarki, rashin kwanciyar hankali, ko lalacewar abubuwan ciki.

H: Canja wutan lantarki ba shi da fitowar DC5V (hasken alamar yana kashewa):

(1) Tabbatar cewa nauyin ba gajere bane. Cire haɗin kebul na tashar jiragen ruwa a bayan mai sarrafawa, yi amfani da mita don gwada ko akwai ɗan gajeren zango tsakanin fil 6 da fil 9 na tashar serial. Tabbatar cewa babu gajeren gajeren zango na ciki (wato, babu gajeriyar madaidaiciya tsakanin fil 6 da fil 9 na tashar serial a bayan mai sarrafawa. Abin mamaki na gajeren zango).

(2) Tabbatar cewa tashar shigarwa tana da AC (170V ～ 250) V, shigarwar ƙarfin lantarki na 50Hz.

(3) Wutar lantarki mai sauyawa kanta ta lalace. Tuntuɓi masana’anta don cire ko maye gurbin.

I: Zazzabin tanderu yana tashi sama da yanayin zafin da aka saita na dogon lokaci a farkon gwajin:

(1) Wayar wutar makera a buɗe take. Bincika ko waya murhun wutar a buɗe take ko ƙarfin cajin bai isa ba (saitin murhun murhu ya karye). Ana iya gwada juriya na murhun wutar lantarki tare da kayan aiki, wanda yawanci kusan 10-15 ohms ne.

(2) An ƙone ko lalacewar ƙaƙƙarfar yanayin jihar. Bincika ko ingantacciyar hanyar ba da gudummawar jihar ta lalace ko wayoyin sarrafawa ba su cikin hulɗa mai kyau.

(3) The voltage is low low.

J: Babu dumama ko babu dumama

(1) Wayar wutar makera a buɗe take. Bincika ko wayar murhun a buɗe take, buɗe murfin baya na murhun murfi, kuma gwada juriya na waya tanderu da mita. Yawanci, yana kusan 10-15 ohms. (Bincika idan haɗin tashoshin yana cikin amintaccen lamba)

(2) An ƙone ko lalacewar ƙaƙƙarfar yanayin jihar. Bincika ko ingantacciyar hanyar ba da gudummawar jihar ta lalace ko wayoyin sarrafawa ba su cikin hulɗa mai kyau.

(3) The thermocouple yana da kewaye kewaye. Bincika idan akwai kewaye mai buɗewa, sannan sake kunna na’urar bayan kashewa

(4) Hanyar sarrafawa ba daidai ba ce. Bincika ko an saka layin bayanan tashar tashar jiragen ruwa cikin aminci da tabbaci, kuma duba ko ingantacciyar hanyar kula da layin ba da gudummawar jihar tana cikin amintacciyar lamba

(5) Matsalar mai sarrafawa. Tuntuɓi masana’anta.

K: Ana caje yadi:

(1) Duba ko layin wutar lantarki ya lalace ko yana da haɗin zane na waya tare da shari’ar.

(2) Duba ko waya ta ƙasa na wutan lantarki tana cikin amintacciyar lamba ko ta ɓace.

(3) Busasshen iska da wutar lantarki a tsaye.
