An urumuri rwerekanaikoreshwa cyane cyane kumuzunguruko cyangwa ibikoresho bya mashini mugukurikirana no gutabaza imikorere yimikorere yibikoresho.Igikoresho, gikurikirana imikorere cyangwa imyanya yumuzunguruko nibikoresho byamashanyarazi ukoresheje itara.Itara ryerekana ubusanzwe rikoreshwa mukugaragaza imikorere yumuzunguruko (amashanyarazi cyangwa udafite amashanyarazi), imikorere y ibikoresho byamashanyarazi (imikorere, guhagarika cyangwa kugerageza) hamwe na leta ihagaze (ifunze cyangwa idahuye), nibindi .Itara ryerekana ikoreshwa bisanzwe amabara ni umutuku, icyatsi, umuhondo, ubururu, umweru.Umuhondo bisobanura kwihagararaho, icyatsi bisobanura gukora bisanzwe, umutuku bisobanura guhagarara byihutirwa. Ibara ryamabara ningenzi yibara rihuza ibara, uburebure bwumuraba nyamukuru, ibara ryera, ubushyuhe bwamabara niterambere ryamabara, nibindi, uburyo bwikizamini nuburyo bwa spekitroscopique nuburyo bwuzuye. Ibicuruzwa byatsi nicyera byumva amashanyarazi ahamye, mugukoresha ibikenewe kwitondera ubwiyongere bwumuriro wamashanyarazi uza kwangiza cyangwa kwangiza ibicuruzwa, kandi ibicuruzwa bihura numwanya wakazi ndakwinginze ukoreshe icyuma kiyobora unyuze mubitaka;Isonga y'icyuma kigurisha igomba kuba ihagaze;Amashanyarazi ya Ion arasabwa.

Amashanyarazi aranga ibipimo bya LED harimo imbere yimbere, imbere yimbere, voltage ihindagurika na voltage yinyuma.Iki kizamini gisanzwe gikoreshwa mugukoresha voltage ammeter mugihe cyumuvuduko uhoraho kandi uhoraho wa voltage.Ibipimo ntarengwa byemerwa imbere yumubyigano, imbere yimbere ninyuma ya voltage numuyoboro urashobora kuboneka mugupima ibiranga amashanyarazi ya LED.Mubyongeyeho, imbaraga zamashanyarazi zikora neza za LED nazo zirashobora kuboneka.
