Voltage tester kye kimu ku bintu ebikulu eri abakugu mu by’amasannyalaze, bayinginiya b’amasannyalaze, n’abakozesa amaka bonna okusobola okugonjoola ebizibu by’amasannyalaze. Ka kibeere nti okebera vvulovumenti mu nkulungo y’awaka oba okugonjoola embeera y’amaanyi g’ebyuma by’amakolero, okukuguka mu bukodyo obutuufu obw’okukozesa kijja kulongoosa obulungi bw’okupima n’okukakasa obukuumi. Wano waliwo amagezi ag’omugaso okukuyamba okukola ekigezo kya vvulovumenti mu ngeri entuufu.
1. Okulonda ekikebera vvulovumenti ekituufu .
Nga tonnatandika kupima, kakasa nti voltage tester yo esaanira ekika ne voltage range ya circuit gy’ogezesa. Ebigezesa vvulovumenti ebya bulijjo mulimu:
• Digital Multimeter (DMM): Esaanira okupima obulungi amasannyalaze agakyukakyuka (AC) ne direct current (DC) voltages, nga gawa obutuufu obw’amaanyi n’emirimu egy’enjawulo.
• Analog Voltmeter: Okuddamu amangu, okusaanira okuzuula amangu okubeerawo kwa vvulovumenti, naye okusoma si kwa mazima nga mita za digito.
• Non-Contact voltage tester (NCVT): ezuula AC voltage nga tekwata ku waya, ekigifuula esaanira okugonjoola amangu embeera za voltage enamu, naye tesobola kupima specific voltage levels.
Amagezi: Nga tonnaba kupima, kakasa nti ekigezo ky’omugezi (okugeza, AC 0-1000V oba DC 0-20V) okwewala okupima okusukkiridde n’okwonooneka okuyinza okubaawo.
2. Obukuumi Okusooka: Yambala eby’okwekuuma mu butuufu .
Okugezesa vvulovumenti kuzingiramu obukuumi bw’amasannyalaze, n’olwekyo okunywerera ddala ku mateeka agakwata ku byokwerinda:
• Glove ne goolo eziteekeddwamu omusana: Bulijjo yambala ebyuma ebikuuma nga opimira mu mbeera za vvulovumenti eza waggulu-.
• Amasannyalaze-OFF (bwe kiba kyetaagisa): Bwe kiba kisoboka, ggyamu amasannyalaze nga tonnaba kukola bipimo naddala ng’olina okugonjoola ebizibu.
• Kozesa jack za lead ez’okugezesa entuufu: Yunga ekisumuluzo ekiddugavu eky’okugezesebwa ku DMM’s COM jack n’okugezesebwa okumyufu ku jack ya VΩma (Special jacks ziyinza okwetaagisa ku bipimo bya voltage ebya waggulu-).
Amagezi: Bw’oba opimira vvulovumenti enkulu (okugeza, 220V/380V), kuuma omulimu gumu-ekola n’emikono okwewala okukola olukoba era ekiyinza okuleetawo okukuba kw’amasannyalaze.
3. Gatta bulungi tester .
Nga opima vvulovumenti, omugezi alina okuyungibwa mu parallel ne circuit, so si mu series (series connection yeetaagibwa ku current measurements zokka).
• Okupima vvulovumenti ya AC: Koona ku kigezo ekimyufu n’ekiddugavu kituusa ku waya enlamu ne neutral (oba kondakita okugezesebwa), mu kulondako, okukakasa okukwatagana okulungi wakati wa leads ne kondakita.
• Okupima vvulovumenti ya DC: Faayo ku polarity: Gatta ekigezo ekimyufu ekivaako ekitundu kya positiivu ate ekigezo ekiddugavu kivaako ekitundu ekibi. Obutakikola kiyinza okuvaamu okusoma obubi oba okwonooneka ku mita.
Amagezi: Bw’oba opima vvulovumenti ya bbaatule, sooka okakasizza polarity okwewala reverse polarity.
4. Amagezi ag’okukozesa ekintu ekitali-Kyusi .
Non-Ebigezesa vvulovumenti bikwatagana (nga ekkalaamu egezesebwa) bisaanira okuzuula amangu oba waya oba ekifuluma kiri live:
• Ggala okugezesa okumpi: Kwata omugezi okumpi ne waya oba ekifuluma. Singa ettaala y’ekiraga eyaka oba amaloboozi ga buzzer, vvulovumenti ebaawo.
• Okwewala ebirungi eby’obulimba: Ebyuma ebimu (nga amaanyi-ebitaala ebikekkereza n’ebyuma eby’amasannyalaze) biyinza okuleeta okutaataaganyizibwa kw’amasannyalaze okunafu, ekivaamu ebirungi eby’obulimba. Kirungi okugatta okupima okukwatagana n’okukakasa.
Amagezi: Mu mbeera ezitali zimu, NCVT ezimu zijja kwaka okusobola okwanguyirwa okwetegereza, naye ekitangaala eky’amaanyi kiyinza okukosa okusalawo.
5. Amagezi ku kulongoosa obutuufu bw’okupima .
• Okulonda ekika ekituufu: Bw’oba tolina bukakafu ku vvulovumenti, tandika n’olunyiriri olusinga obunene n’oluvannyuma mpolampola okutereeza okutuuka ku bbanga okusobola okulongoosa obutuufu.
• Okwewala okutaataaganyizibwa: Bw’opima mu mbeera ey’amaanyi ey’amasannyalaze (nga okumpi ne mmotoka), okusoma kuyinza okukosebwa. Gezaako okwewala ensonda z’okuyingirira.
• Okusoma okutebenkedde: mita ya digito eyinza okuwuuma olw’enkyukakyuka ya vvulovumenti. Linda omuwendo guteredde nga tonnakwata.
Amagezi: Bw’oba opimira vvulovumenti entonotono (nga milivolts ntono), kozesa ekipimo kya waggulu-precision multimeter oba differential probe.
6. Ensobi n’okugonjoola ebizibu ebitera okubaawo .
• "OL" oba "1" eraga: Kino kiraga embeera ya over-ebanga. Yongera ku bbanga oba kebera oba tewali voltage mu circuit.
• Okusoma okutali kwa ntebenkevu: Kino kiyinza okulaga okukwatagana obubi oba okutaataaganyizibwa mu nkulungo. Ddamu osseeko leads z’okugezesa oba kyusa ekifo we bapimira.
• Battery entono: Battery entono mu mita ya digito esobola okuleeta okusoma okutali kutuufu. Battery zikyuseemu buli kiseera.
Mu bufunzi
Okukuguka mu nkozesa entuufu ey’ekigezo kya vvulovumenti tekikoma ku kulongoosa bulungibwansi bw’okupima wabula era kikakasa obukuumi bw’emirimu. Ka obe nga weekebejja enkola y’amasannyalaze g’awaka oba ng’okola okuddaabiriza n’omusawo w’amasannyalaze omukugu, okusiiga obukodyo buno kijja kukuyamba okukola omulimu gwonna ogw’okugezesa vvulovumenti n’obuvumu. Jjukira nti obukuumi bulijjo busooka!
