Nka kimwe mu bikoresho byingenzi mu bijyanye no gupima amashanyarazi, iterambere rya metero imwe - icyiciro cy’amashanyarazi gifitanye isano rya bugufi n’ihindagurika ry’imibereho y’abantu ikoresha amashanyarazi. Kuva amashanyarazi manini - yakoreshejwe mu mpera z'ikinyejana cya 19, kugaragara no kunoza metero z'amashanyarazi ntabwo byateje imbere ubumenyi mu micungire y’ingufu gusa ahubwo byanagize ingaruka zikomeye ku mikoreshereze y’amashanyarazi mu nganda zigezweho no mu mibereho yo guturamo.
Mu myaka ya 1880, hamwe no guteza imbere sisitemu yo kubyara amashanyarazi ya Edison itaziguye, ibikoresho bya mbere byo gupima amashanyarazi byaje kubaho. Mu 1889, injeniyeri w’Ubudage Hermann Aron yahimbye metero y’ingufu z’amashanyarazi ashingiye ku ihame rya electrolytike, ryabaze mu buryo butaziguye gukoresha ingufu mu gupima iyimuka ry’ibyuma mu mazi. Nyamara, iki gikoresho cyari gifite ubunyangamugayo buke no kubungabunga ibintu bigoye, ku buryo kumenyekanisha bigoye. Mu myaka ya 1890, izamuka rya sisitemu zigenda zisimburana byatumye habaho ingufu z'amashanyarazi zikoreshwa cyane. Mu 1896, umuhanga w’umunyamerika Elihu Thomson yateguye metero yambere y’amashanyarazi - icyiciro cy’amashanyarazi. Iri koranabuhanga, ryifashishije ihame ryo kuzenguruka disiki ya aluminiyumu itwarwa n’umurima wa magneti uhinduranya, wageze ku gupima mu buryo butaziguye ingufu z’amashanyarazi. Bitewe nuburyo bworoshye kandi bwizewe cyane, iri koranabuhanga ryabaye igisubizo nyamukuru kwisi yose mugice cya mbere cyikinyejana cya 20.
Hagati ya - kugeza - mu mpera z'ikinyejana cya 20, iterambere mu ikoranabuhanga rya elegitoronike ryateje udushya muri metero z'amashanyarazi. Mu myaka ya za 70, ikoreshwa ryumuzunguruko wahujwe byatumye metero yumuriro wa elegitoronike isimbura buhoro buhoro metero gakondo, itanga ibipimo bihanitse kandi birinda ubudahangarwa. Mu mpera z'ikinyejana cya 20, kwinjiza ikoranabuhanga rya microprocessor byongereye ingufu za metero z'amashanyarazi hamwe no kubika amakuru ndetse n'ubushobozi bwo gutumanaho bwa kure, bishyiraho urufatiro rwo guteza imbere imiyoboro y'ubwenge. Kuva mu kinyejana cya 21, metero imwe ya - icyiciro cya mashanyarazi yagiye buhoro buhoro yerekeza kuri digitale no guhuza imiyoboro, ishyigikira ibipimo byombi kandi ikurikirana - igihe, ikemura ibibazo bikwirakwizwa n’ingufu zikoreshwa hamwe n’ubuyobozi -.
Kuva ku bikoresho bya mashini kugeza kuri chip zifite ubwenge, amateka ya metero imwe - icyiciro cyamashanyarazi yerekana ubumuntu budasubirwaho gushakisha ingufu. Uyu munsi, ntabwo ari igikoresho cyo gukemura fagitire y’amashanyarazi gusa, ahubwo ni n’ingirakamaro mu mbaraga za interineti, bikomeza gutanga ubufasha bwa tekinike mu guhindura ingufu z’isi.
