Mugihe cya AC test voltage, uburyo bukoreshwa muburyo bwo gupima gusohora igice nuburyo bukurikira:
(1) Icyitegererezo
Mbere yikizamini, icyitegererezo kigomba kubanzirizwa hakurikijwe amabwiriza abigenga:
1. Gumana ubuso bwibicuruzwa byipimishije kandi byumye kugirango wirinde kwaduka kwatewe nubushuhe cyangwa umwanda hejuru yubushuhe.
2. Mugihe habuze ibisabwa byihariye, icyitegererezo kigomba kuba mubushyuhe bwibidukikije mugihe cyizamini.
3. Nyuma yubukanishi bwabanjirije, ubushyuhe cyangwa amashanyarazi, ibicuruzwa byikizamini bigomba gusigara mugihe runaka mbere yikizamini, kugirango bigabanye ingaruka zibyo bintu byavuzwe haruguru kubisubizo byikizamini.
(2) Reba igice cyo gusohora igice cyumuzingi wikizamini ubwacyo
Ntukabanze uhuze ibicuruzwa byikizamini, ariko koresha voltage gusa kumuzingo wikizamini.Niba nta gusohora igice bibaho munsi yumubyigano wikigereranyo urenze gato ibicuruzwa byapimwe, umuzenguruko wikizamini urabishoboye;niba igice cyo gusohora igice cyarenze cyangwa cyegereye ubushobozi bushoboka bwo gusohora ibicuruzwa byipimishije 50% byagaciro, inkomoko yo kwivanga igomba kumenyekana kandi hafashwe ingamba zo kugabanya urwego rwivanga.
(3) Calibration ya loop ikizamini
Igikoresho kiri mukuzunguruka kigomba guhindurwa muburyo busanzwe mbere yigitutu kugirango hamenyekane igipimo cyibipimo byumuzunguruko wikizamini mugihe ibicuruzwa byipimishije bihujwe.Iyi coefficient yibasiwe nibiranga uruziga hamwe nubushobozi bwibicuruzwa byipimishije.
Munsi ya Calibrated circuit sensitivite, reba niba hari intambamyi nini mugihe amashanyarazi menshi adahujwe cyangwa nyuma yumuriro w'amashanyarazi mwinshi uhujwe, kandi niba aribyo, gerageza kubikuraho.

Kuraho igikoresho cya kalibrasi kandi ukomeze izindi nsinga zidahindutse.Iyo imiyoboro ya voltage yikizamini yujuje ibisabwa, voltage yongewe kuri voltage iri munsi yumubyigano uteganijwe gusohora igice cya voltage, kandi voltage ikazamuka kumuvuduko wagenwe kugeza igihe ubushobozi bwo gusohora bugera ku giciro cyagenwe.Umuvuduko muriki gihe nigice cyo gusohora igice cya voltage.Noneho voltage yiyongereyeho 10%, hanyuma voltage iramanurwa kugeza igihe ubushobozi bwo gusohora bungana nagaciro kavuzwe haruguru, kandi voltage ijyanye nayo ni ukuzimya gusohora igice.Iyo upimye, voltage ikoreshwa ntabwo yemerewe kurenza igipimo cyagereranijwe cyumubyigano wikizamini.Mubyongeyeho, gusubiramo inshuro nyinshi za voltage hafi yayo birashobora kwangiza ikintu cyikizamini.
(5) Gupima gusohora igice munsi ya voltage yagenwe
Birashobora kugaragara uhereye hejuru ko ibipimo biranga gusohora igice byose bipimirwa kuri voltage yihariye, ishobora kuba hejuru cyane kurenza igice cyo gusohora igice cya voltage.Rimwe na rimwe, hateganijwe gupima ubushobozi bwo gusohora munsi y’amashanyarazi menshi, kandi rimwe na rimwe harateganijwe gukomeza igihe runaka munsi y’umubyigano runaka kandi ugakora ibipimo byinshi kugira ngo harebwe icyerekezo cyiterambere cyo gusohora igice.Mugihe upima ingano isohoka, irashobora kandi gupima umubare wibisohoka, impuzandengo isohoka hamwe nibindi bipimo bisohora igice.
1. Gupima nta voltage yabanje gukoreshwa
Mugihe cyikizamini, voltage kuri sample igenda yiyongera buhoro buhoro kuva ku giciro cyo hasi kugeza ku giciro cyagenwe, kandi ikabikwa mu gihe runaka mbere yo gupima ibyasohotse igice, hanyuma ikagabanya voltage no guhagarika amashanyarazi.Gusohora igice rimwe na rimwe bipimwa mugihe cya voltage yuzuye, hejuru, cyangwa mugihe cyibizamini kuri voltage yagenwe.
2. Gupima hamwe na voltage yabanje gukoreshwa
Mugihe cyikizamini, voltage yiyongera buhoro buhoro uhereye ku giciro cyo hasi, kandi nyuma yo kurenga igice cyateganijwe cyo gusohora igice cyumubyigano, irazamuka kuri voltage yabanje gukoreshwa, ikagumana mugihe runaka, hanyuma ikamanuka mukigeragezo cya voltage, ikomeza igihe cyagenwe, hanyuma igapima mugihe runaka intera isohoka igice.Mugihe cyose cya voltage ikoreshwa, hagomba kwitonderwa itandukaniro ryumubare wogusohora igice.
