DFUN AC Ingufu za Metero zerekana igikoresho cyambere cyo gupima ibipimo byamashanyarazi, byabugenewe byumwihariko mugukurikirana-gihe no gusesengura sisitemu yingufu. Izi mbaraga za AC Ingufu zikoresha tekinoroji ya elegitoroniki nini nini nini ihuriweho, ikoresha tekinoroji yo gutunganya ibikoresho bya digitale hamwe na Surface Mount Technology (SMT). Byongeyeho, bemera kumurongo wibintu gushiraho binyuze muri push-buto kandi birangwa nubunini bwacyo, uburemere bworoshye, igishushanyo mbonera, hamwe nuburyo bworoshye bwo kwishyiriraho.

DFUN Imiyoboro myinshi ya metero irashobora gupima voltage, ikigezweho, nimbaraga kuri buri muzunguruko mugihe nyacyo, byemeza imikorere ihamye ya sisitemu yingufu. Ubushobozi buhanitse bwo gupima butuma ifata mugihe cyimpinduka zingirakamaro mumashanyarazi, zitanga amakuru yizewe kubikorwa byo gufata neza no kubungabunga. Izi mbaraga za DC zigaragaza imikorere inoze yo gupima ingufu, gupima neza ingufu zose zikoreshwa mumuzunguruko, zifasha mugucunga ingufu no kugenzura ibiciro hifashishijwe isesengura rirambuye ryimikoreshereze yingufu.
