I-A5 Portable Voltage Current Tester Digital Multimeter

Incazelo Yomkhiqizo

Le divayisi encane isebenziseka ngezindlela eziningi futhi ifanele ochwepheshe kanye nabathandi be-DIY ngokufanayo. Ama-multimeter aklanywe ngendlela elula engqondweni. Anezinketho zokukhetha ububanzi ngokuzenzakalelayo, okukuvumela ukuthi ushintshe kalula phakathi kwezilungiselelo zokulinganisa ezahlukene ngaphandle kokulungisa ububanzi ngesandla. Lokhu kukongela isikhathi futhi kuqinisekisa imiphumela enembile njalo. Ngokuvikelwa kokudlula kobubanzi bokulinganisa okugcwele, ungaqiniseka ukuthi i-multimeter yakho ingaphatha ama-voltage aphezulu kanye nemisinga ngaphandle kokulimala. Lesi sici sikunikeza ukuthula kwengqondo futhi sivikela impilo yedivayisi yakho. I-multimeter ifakwe imodi ezenzakalelayo eqaphela ngokuzenzakalelayo uhlobo lwesignali kagesi elinganiswayo, kungakhathaliseki ukuthi yi-AC volts, i-DC volts, ukumelana, noma ukuqhubeka. Lokhu kuqeda isidingo sokukhetha ngesandla futhi kuqinisekisa ukufundwa okunembile kwezingxenye ezahlukene zikagesi. I-multimeter inesibonisi se-LCD esicacile esinezinombolo ezingu-6000 zokulinganisa, enikeza imiphumela elula ukuyifunda. Iphinde ifake inkomba ye-polarity, enophawu "-" lwe-polarity engemihle. Lokhu kuqinisekisa ukuchazwa okunembile kwemiphumela yokulinganisa. Uma ukulinganisa kungaphandle kobubanzi, i-multimeter izobonisa "OL" noma "-OL" ukukhombisa ukudlula kobuningi, ivimbele ukufundwa okungamanga. Ngesikhathi sesampula esheshayo esingaba yimizuzwana engu-0.4, uthola imiphumela esheshayo nenembile yokuxazulula izinkinga ngempumelelo.

Ukuze kulondolozwe impilo yebhethri, i-multimeter inesici sokuvala ngokuzenzakalelayo esisebenza ngemva kwemizuzu eyi-15 yokungasebenzi. Lokhu kusiza ukwandisa impilo yebhethri futhi kukusindise ekubeni udinga ukushintsha amabhethri njalo. Ngaphezu kwalokho, uphawu lwesibonakaliso sebhethri eliphansi esikrinini se-LCD luzokukhumbuza ukuthi ibhethri lidinga ukushintshwa nini. I-multimeter ingamelana nezimo ezahlukahlukene ngebanga lokushisa lokusebenza elingu-0-40°C kanye nebanga lomswakama elingu-0-80%RH. Ingagcinwa futhi ngokuphephile emazingeni okushisa angu--10-60°C kanye namazinga omswakama afinyelela ku-70%RH. Lokhu kuqinisekisa ukuqina nokuthembeka ngisho nangaphansi kwezimo ezinzima. I-multimeter isebenza ngamabhethri amabili angu-1.5V AAA ukuze inikeze amandla ahlala isikhathi eside ngezidingo zakho zokulinganisa. Umklamo olula unesisindo esingamagremu angu-92 kuphela (ngaphandle kwebhethri) kanye nosayizi omncane ongu-139.753.732.8 mm ukuze kube lula ukuwuthwala. Ama-multimeter ethu afanele ochwepheshe bakagesi, ochwepheshe kanye nabantu abathanda ukuzijabulisa abadinga ukwenza izilinganiso ezinembile ezinhlotsheni ezahlukene zokusebenza kukagesi. Izici zayo ezilula ukuzisebenzisa kanye nokusebenza okuthembekile kuyenza ibe yinto ewusizo ebhokisini lakho lamathuluzi.
