Kuberako Asfalt ivanze ecran yoroshye: Koresha urugendo rumwe nta mutwaro, hanyuma utangire urugendo. Nyuma yo gusimbuza relay nshya yubushyuhe, amakosa aracyahari. Reba umubonano, kurwanya moteri, imyigaragambyo hamwe na voltage, nibindi, kandi ntakibazo cyabonetse; Kuramo umukandara woherejwe, tangira ecran yo kunyeganyega, Ammeter yerekana ibisanzwe, kandi ntakibazo cyo gutembera muminota 30 nta gikorwa cyo gupakira. Ikosa ntabwo ari mu gice cy'amashanyarazi. Nyuma yo kohereza umukandara woherejwe, ecran yo kunyeganyega yabonetse cyane yatsinzwe cyane na eccentric.
Guhagarika eccentric guhagarika, tangira ecran yo kunyeganyega, Ammeter yerekana imyaka 15; Metero ya magnetic yashizweho ku isahani ya ecran yo kunyeganyega, hagenzurwa na radio igenzurwa no gushyira ahagaragara igiti, hamwe na kogo ya radiyo ni mm 3,5; Oval ntarengwa ya diameter yimbere ni 0.32 mm. Simbuza ecran yo kunyeganyega, shyiramo eccentric blok, ongera utangire kuri ecran yo kunyeganyega, kandi Ammeter yerekana ibisanzwe. Nta rugendo ruzongera kubaho.
