Ibice bitatu - icyiciro cyamashanyarazi nibikoresho byingenzi bikoreshwa mumashanyarazi kugirango bapime neza bitatu - icyiciro cyo gukoresha ingufu za AC. Zikoreshwa cyane mubikorwa byinganda, ubucuruzi, nuburyo bunini bwo guturamo. Amahame yabo ya tekiniki ashingiye kumashanyarazi ya electronique cyangwa tekinoroji yo gupima ibikoresho. Mugukusanya ibintu bitatu - icyiciro cya voltage nicyapa kigezweho, babara indangagaciro zumubare wimbaraga zikora, zidasanzwe, nimbaraga zigaragara, amaherezo bakagera kubisesengura ryimibare yingufu zamashanyarazi.
Muburyo, gakondo eshatu - icyiciro cyamashanyarazi akenshi ikoresha imashini ikora amashanyarazi. Imikoranire ya magnetiki flux itangwa na voltage hamwe na coil igezweho itwara kuzenguruka kwa disiki ya aluminium, hamwe n umuvuduko wo kuzenguruka ugereranije nimbaraga. Uburyo bwo kohereza ibikoresho byegeranya kuzenguruka no kwerekana gusoma. Ibyuma bya elegitoroniki bigezweho - icyiciro cyamashanyarazi yishingikiriza kuri microprocessor hamwe na - igereranya risobanutse - kugeza - ihindura imibare (ADCs). Berekana mu buryo butaziguye indangagaciro ako kanya ya - icyiciro cya voltage nicyiciro, babara imbaraga zako kanya bakoresheje uburyo bwo gutunganya ibimenyetso bya digitale, kandi bagahuza amakuru yingufu. Imashanyarazi ya elegitoroniki itanga ubuziranenge bwo gupima, ubudahangarwa bukomeye bwo kwivanga, kandi igashyigikira ubushobozi bwitumanaho nka RS - 485, imiyoboro yabatwara, cyangwa itumanaho ridafite insinga, byorohereza gucunga amashanyarazi. Inyungu yibanze ya metero eshatu - icyiciro cyamashanyarazi kiri mubushobozi bwabo bwo kwakira imitwaro iringaniye kandi itaringanijwe -. Ibikoresho byinganda mubisanzwe bikoresha amashanyarazi ibyiciro bitatu kugirango bitezimbere imikorere, kandi metero zamashanyarazi zigomba gupima neza umubare wa vector yingufu za buri cyiciro kugirango hamenyekane neza amakuru yimbaraga zose. Byongeye kandi, metero z'amashanyarazi zigezweho akenshi zihuza ibintu nko gusesengura guhuza, imibare isabwa, no gutema amashanyarazi, gutanga amakuru yo kugenzura imiterere ya gride no gukoresha neza ingufu z'abakoresha.
Kurwego rwo gusaba, gutoranya metero eshatu - icyiciro cyamashanyarazi bisaba gutekereza kuri voltage yagenwe, intera iriho, hamwe nibidukikije. Kurugero, ibintu byinganda bishobora gusaba metero kugirango bihangane n’imihindagurikire y’imizigo n’ubushyuhe bukabije, mu gihe inyubako z’ubucuruzi zishyira imbere guhuza itumanaho. Hamwe niterambere rya gride yubwenge, metero yumuriro wamashanyarazi ifite ubushobozi bwa IoT iragenda ihinduka nyamukuru, ishyigikira nyabyo - igihe cyo kugiciro cyibiciro byamashanyarazi no gukwirakwiza imicungire yumutungo w'ingufu, kurushaho kunoza imikorere ya sisitemu no gukoresha abakoresha.
Mu bihe biri imbere, tekinoroji ya metero eshatu - izakomeza gutera imbere igana ku buryo bunoze, guhuza imiyoboro, hamwe no guhuza ibikorwa -, biba ibikorwa remezo byubaka sisitemu y’ingufu zikora neza, zizewe, kandi zirambye.
