I-A5 Portable Voltage Current Tester Digital Multimeter

Incazelo Yomkhiqizo

Le divayisi ehlangene inezinto eziningi futhi ifanele izingcweti kanye nabathandi be-DIY ngokufanayo.Ama-Multimeter aklanywe ngokunethezeka engqondweni.Ifaka phakathi ukukhetha kwebanga okuzenzakalelayo, okukuvumela ukuthi ushintshe kalula phakathi kwezilungiselelo ezihlukene zokulinganisa ngaphandle kokuthi ulungise mathupha ububanzi.Lokhu kongela isikhathi futhi kuqinisekisa imiphumela enembile ngaso sonke isikhathi.Ngokuvikelwa kokulayisha ngokweqile kobubanzi bokulinganisa, ungaqiniseka ukuthi i-multimeter yakho ingaphatha ama-voltage aphezulu namaza ngaphandle kokulimala.Lesi sici sikunikeza ukuthula kwengqondo futhi sivikela impilo yedivayisi yakho.I-multimeter ifakwe imodi ezenzakalelayo ebona ngokuzenzakalela uhlobo lwesiginali kagesi elinganiswayo, noma ngabe ama-volts e-AC, ama-volts e-DC, ukumelana, noma ukuqhubeka.Lokhu kuqeda isidingo sokukhethwa ngesandla futhi kuqinisekisa ukufundwa okunembile kwezingxenye ezahlukene zikagesi.I-multimeter inesibonisi se-LCD esicacile esinamadijithi angu-6000 wezilinganiso, ahlinzeka ngemiphumela efundeka kalula.Kuhlanganisa futhi inkomba ye-polarity, enophawu "-" lwe-polarity engalungile.Lokhu kuqinisekisa ukuhunyushwa okunembile kwemiphumela yokulinganisa.Uma ukulinganisa kungaphandle kwebanga, i-multimeter izobonisa "OL" noma "-OL" ukukhombisa ukugcwala, ukuvimbela ukufundwa okungamanga.Ngesampula esheshayo yesikhathi cishe esingamasekhondi angu-0.4, uthola imiphumela esheshayo nenembile yokuxazulula inkinga okuphumelelayo.

Ukuze ulondoloze impilo yebhethri, i-multimeter inesici sokuvala amandla esizenzakalelayo esisebenza ngemva kwemizuzu engu-15 yokungasebenzi.Lokhu kusiza ukunweba impilo yebhethri futhi kukusindise ekubeni ushintshe amabhethri njalo.Ngaphezu kwalokho, uphawu lwebhethri oluphansi esikrinini se-LCD luzokukhumbuza uma ibhethri idinga ukushintshwa.I-multimeter ingakwazi ukumelana nezindawo ezihlukahlukene ezinezinga lokushisa elisebenzayo lika-0-40°C kanye nebanga lomswakamo lika-0-80%RH.Ingabuye igcinwe ngokuphephile emazingeni okushisa ayi-10-60°C namazinga omswakama afinyelela ku-70% RH.Lokhu kuqinisekisa ukuqina nokuthembeka ngisho nangaphansi kwezimo eziyinselele.I-multimeter isebenza ngamabhethri amabili angu-1.5V AAA ukuze ikunikeze amandla ahlala isikhathi eside ezidingo zakho zokulinganisa.Idizayini engasindi enesisindo esingamagremu angu-92 kuphela (ngaphandle kwebhethri) nosayizi ohlangene we-139.753.732.8 mm ukuze iphatheke kalula.Ama-multimeters ethu alungele ochwepheshe bakagesi, ochwepheshe kanye nabazilibazisayo abadinga ukwenza izilinganiso ezinembile ezinhlotsheni zokusebenza zikagesi.Izici zayo ezisebenziseka kalula nokusebenza okuthembekile kuyenza ibe isengezo esibalulekile ebhokisini lakho lamathuluzi.
