Ubushobozi buke bwo gupima nuburemere buke bwo gupima igipimo gishobora kugira ngo hatabaho ikosa rikabije ugereranije mubisubizo byo gupima.Ni ubuhe butumwa bukwiye kuba “ubushobozi buke bwo gupima”?Iki nikibazo gikwiye gushimangirwa kuri buri gipimo mubikorwa byacu bifatika.Kuberako hari umunzani ukoresheje ibice, mugihe uhisemo umunzani, batekereza gusa kuzigama amafaranga yo kugura, kugabanya umubare wiminzani yaguzwe bishoboka, kandi niba bashobora gukoresha umunzani umwe kugirango bapime ibintu byinjira nibisohoka mubice, bo rwose ntibashaka kugura umunzani ibiri ifite ubushobozi butandukanye bwo gupima.
Turimo kuganira gusa kubushobozi buke bwo gupima "umunzani wa nonautomatic", ntabwo ubushobozi buke bwo gupima "umunzani wikora" bijyanye.Impamvu nuko buri cyiciro cyibice bitandatu by "umunzani wikora" gifite byibura ibipimo byibura byo gupima, kandi byumvikane ko byose byashizweho kugirango bigenzure neza ibipimo byabo.
Mu gitabo cy’umwaka wa 2006 cy’icyifuzo mpuzamahanga R76 “Ibikoresho byo gupima Nonautomatic”, ubushobozi ntarengwa bwo gupima buri cyiciro cy’ibice bine bitandukanye byerekana umunzani bwerekanwe kandi bwanditse neza “Ubushobozi buke bwo gupima (Limit Limit)”.
Kubwibyo, nkumushinga winganda nishami ryubuyobozi bwa metrologiya bigomba gusobanurira abakoresha igipimo ko bagomba kohereza umunzani ufite ibipimo bitandukanye bipima mubigo byabo kugirango barebe ko umunzani utandukanye ukoreshwa mubintu bifite uburemere butandukanye, kugirango barebe ko gushyira mu gaciro mu gukemura ibicuruzwa.
Mu Bushinwa amabwiriza yo gupima no kugenzura muri iki gihe, niba igipimo gishobora kuba cyujuje ibisabwa n'amabwiriza abigenga, mu igenzura rya mbere na nyuma yo kugenzura byibura umunzani watoranijwe, kandi rigomba kuba rikubiyemo: igipimo ntarengwa, impinduka ntarengwa zemewe mu bipimo ( 500e, 2000e kurwego rwo hagati rwukuri, 50e, 200e kurwego rusanzwe rwukuri), 1/2 igipimo ntarengwa, igipimo ntarengwa.Niba ubushobozi buke bwo gupima ari 20e gusa, cyangwa 50e gusa, mugihe ikosa ryemewe ari 1 kalibrasi, ikosa rigereranijwe ni 1/20 cyangwa 1/50.Iri kosa rifitanye isano ntacyo risobanura kubakoresha.Niba ikoreshwa ryikigo ryasabwe mu buryo bweruye kugirango hamenyekane ubushobozi buke bwo gupima burenze 500e, urwego rwemeza ntirushobora kuba 500e yubushobozi bwo gupima ibyemezo.
Kubipimo byo gupima kutamenya neza imashini ipima ibikoresho bya elegitoronike, ubushobozi ntarengwa bwo gupima, 500e, 2000e bwatoranijwe muri rusange
ingingo eshatu zipima, kandi munsi ya 500e yo gupima ntikiri nkisuzuma ryumushinga.Noneho munsi ya 500e yo gupima uburemere bwo gupima, birashobora kandi kumvikana nkibikubiye mubisuzuma, bigomba noneho kubyara "gupima byibuze" iyi ngingo uburyo bwo guhitamo intego.
