Na biyu, matakai da hanyoyin auna juriya
1. Cire haɗin wutar lantarki sannan a cire murfin fanka don fallasa juriyar.
2. Yi amfani da na'urar multimeter don taɓa sandar aunawa zuwa ƙarshen juriyar biyu. Ya kamata a saita na'urar multimeter zuwa na'urar auna juriya. Idan juriyar za ta daidaita, saita na'urar multimeter zuwa na'urar rheostat don a iya karanta juriyar daidai.
