DFUN AC Ingufu Ibicuruzwa byerekana igikoresho cyambere cyo gupima amashanyarazi, byateguwe cyane cyane ku gukurikirana no gusesengura sisitemu. Ibi bikoresho bya AC AC Sters Koresha Ikoranabuhanga rya Microeletronic hamwe numuzunguruko munini uhujwe, uhiga tekinoroji yo gutunganya ikoranabuhanga hamwe nikoranabuhanga ryo hejuru (SMT). Inyongera, zemerera ibipimo byurubuga binyuze mugusunika-buto kandi birangwa nubunini bwabo, uburemere bwumucyo, igishushanyo mbonera, hamwe nuburyo bwo kwishyiriraho.

DFUN DC Metero ya yagenewe gupima amashanyarazi muburyo butaziguye (DC) ibimenyetso byerekana amarelar nkimirasire yizuba nibikoresho bidafite ibinyabiziga kubinyabiziga byamashanyarazi. Birakwiriye kandi kubijyanye na sisitemu yo gutanga imbaraga za DC igezweho muri sisitemu yo gukwirakwiza mu nganda n'inkunga, inyubako rusange, no kubaka make. 

Ntabwo arimura gukorera mu mucyo no kugenzura imikoreshereze y'ingufu gusa ahubwo bizana inyungu zikomeye z'ubukungu n'ibidukikije mugutezimbere ibiyobyabwenge.

Dfun -Umuyoboro mwinshi wibicuruzwa birashobora gupima voltage, ubungubu, n'imbaraga kuri buri muzunguruko mugihe nyacyo, kugirango imikorere ihamye ya sisitemu yingufu. Ubushobozi bwo gupima cyane bwemerera gufatwa mugihe cyimpinduka zingirakamaro mumiyoboro yamashanyarazi, zitanga inkunga yizewe yo gufata ibyemezo bikora no kubungabunga. Iyi mbaraga za DC ingufu zirimo imikorere ikoresha ingufu zingana, gupima neza ibiyobyabwenge byose kuzunguruka, uyobora imicungire y'ingufu no kugenzura ibiciro binyuze mu isesengura rirambuye.
