Ikizamini cya voltage nigikoresho cyingenzi cyo gupima muri sisitemu yingufu, zikoreshwa mugupima urugero rwa voltage mumuzunguruko no kwemeza neza ibikoresho byamashanyarazi. Kugirango hamenyekane ibipimo nyabyo, bigomba guhindurwa no kugenzurwa hakurikijwe uburyo busanzwe bwo gupima. Ibikurikira nuburyo burambuye bwo gupima ibizamini bya voltage.
1. Pre - Gutegura Ikizamini
Mbere yo gutangira kwipimisha, menya neza ko ibintu bikurikira byujujwe:
• Ibisabwa Ibidukikije: Ibidukikije bigomba kuba byumye kandi bitarangwamo ingufu za electromagnetique, hamwe nubushyuhe bugenzurwa hagati ya dogere 10 na dogere 30 nubushuhe butarenga 80% RH.
• Imiterere y'ibikoresho: Ikizamini cya voltage mugeragezwa kigomba kuba kimeze neza, kitarangiritse cyangwa ibice bitagabanije, kandi gifite bateri ihagije (niba bishoboka).
• Ibikoresho bisanzwe: Tegura isoko yo hejuru - isobanutse neza ya voltage (nka voltmeter isanzwe cyangwa kalibatori) ifite uburebure burenze inshuro 3-5 ugereranije nigikoresho kiri mu kizamini kugirango urebe ibisubizo byizewe.
• Ingamba zumutekano: Abakoresha bagomba kwambara uturindantoki, bakareba niba ibidukikije byapimwe bitagira ingaruka zikomeye za voltage, kandi bagahagarika ingufu zose zidakenewe kumuzunguruko uri mu kizamini.
2. Kugaragara no Kugenzura Imikorere
Mbere yikizamini gisanzwe, kora igenzura ryibanze:
• Kugenzura Ibigaragara: Emeza ko ibyerekanwe bisobanutse kandi bitarangiritse, utubuto twitabira, kandi ama terinal nta okiside cyangwa irekuye.
• Ikizamini Cyimikorere: Nyuma yo gukora amashanyarazi kuri tester ya voltage, genzura neza ko itangiye neza, ihinduranya intera neza, kandi ntigaragaze ko idasanzwe cyangwa kode idasanzwe.
3. Zeru na Byuzuye - Kugenzura Ibipimo
• Calibibasi ya Zeru: Niba nta voltage yinjiza (cyangwa ibyinjijwe hafi ya 0V), hindura igikoresho cya zeru (niba gifite ibikoresho) kugirango ibyerekanwe bisome 0.00V cyangwa hafi ya zeru.
• Byuzuye - Calibibasi ya Scale: Shyiramo urwego rwo hejuru rwumubyigano wamashanyarazi asanzwe (urugero, 100V, 500V, cyangwa irenga, bitewe nicyitegererezo cyibizamini) hanyuma uhindure kalibibikoresho ya kalibasi kugirango agaciro kerekanwe gahuye nagaciro gasanzwe, hamwe nikosa muri ± 0.5% kugeza 1%.
4. Ikizamini Cyukuri
• Multi - Urwego Ikigeragezo: Injiza agaciro gasanzwe ka voltage kuri buri cyiciro cyikigereranyo cya voltage (urugero, 2V, 20V, 200V, 1000V), andika agaciro kageragejwe, gereranya nagaciro gasanzwe, hanyuma ubare ikosa.
• Kubara Ikosa: Ikosa=(Agaciro gapimwe - Agaciro gasanzwe) / Agaciro gasanzwe × 100%. Menya neza ko ikosa kuri buri cyiciro ryujuje ibikoresho bya tekiniki (mubisanzwe bisaba ± 1% kugeza ± 3%).
Kugenzura umurongo: Gerageza kuri voltage nyinshi hagati (urugero, 50V, 250V, 500V) kugirango urebe niba agaciro gapimwe gahinduka kumurongo kugirango wirinde amakosa adafite umurongo.
5. Ikizamini gihamye kandi gisubirwamo
• Ikizamini gihamye: Kuri voltage ihamye (urugero, 100V), reba niba gusoma ibizamini bya voltage bigenda muminota 5-10. Mubihe bisanzwe, impinduka zigomba kuba munsi ya ± 0.1%.
• Ikizamini gisubirwamo: Gupima agaciro kamwe ka voltage inshuro nyinshi (urugero, inshuro 5-10) hanyuma ubare gutandukana bisanzwe mubisomwa kugirango urebe ko ikosa risubirwamo riri murwego rwemewe.
6. Isuzuma ryibisubizo byo gusuzuma no gufata amajwi
• Ibipimo byo kwemererwa: Niba ikosa, ituze, hamwe no gusubiramo ibyiciro byose byujuje ibya tekiniki yababikoze, ibizamini bya voltage bifatwa nkuwatsinze ikizamini.
• Gukemura ikibazo cyo kunanirwa: Niba ikosa rirenze urwego rwemewe, birasabwa gusubiramo cyangwa gusana, kandi ibice bitaribyo bigomba gusimburwa nibiba ngombwa.
• Kwandika Ububiko: Inyandiko zirambuye z'itariki y'ibizamini, imiterere y'ibidukikije, amakuru y'ibikoresho bisanzwe, amakuru yo gupima, n'imyanzuro ya nyuma ibikwa kugirango byoroshye gukurikiranwa.
7. Kohereza - Uburyo bwo Kwipimisha
• Kugarura Igenamiterere: Kugarura ibizamini bya voltage kumiterere yinganda cyangwa igenamigambi rikoreshwa kenshi kugirango wizere gukoresha neza.
• Isuku nububiko: Ihanagura igikoresho hejuru yigitambaro cyoroshye hanyuma ubike ahantu humye, hijimye kugirango wirinde ubushyuhe bwinshi nubushuhe kugirango bitagira ingaruka.
Gukurikiza ubu buryo busanzwe, ibipimo bipima ibipimo bya voltage birashobora gukemurwa, bikarinda imikorere yumuriro wa sisitemu. Kwipimisha bisanzwe (bisabwa buri mezi atandatu kugeza kumwaka umwe) nigipimo cyingenzi cyo gukomeza ibikoresho byizewe.
