I-A5 ephathekayo yeVoltage yangoku iTester Digital Multimeter

Ingcaciso yeMveliso

Esi sixhobo sihlanganisiweyo sisebenza ngeendlela ezininzi kwaye sifanelekile kwiingcali kunye nabathandi be-DIY ngokufanayo.Ii-Multimeters ziyilwe ngokulula engqondweni.Ibonisa uluhlu oluzenzekelayo lokukhetha, ikuvumela ukuba utshintshe ngokulula phakathi kweseto ezahlukeneyo zomlinganiso ngaphandle kokulungelelanisa ngokwalo uluhlu.Oku kongela ixesha kwaye kuqinisekisa iziphumo ezichanekileyo ngalo lonke ixesha.Ngomlinganiselo opheleleyo wokhuseleko lomthwalo ogqithisiweyo, unokuqiniseka ukuba i-multimeter yakho inokusingatha i-voltages ephezulu kunye nemisinga ngaphandle komonakalo.Eli nqaku likunika uxolo lwengqondo kwaye likhusela ubomi besixhobo sakho.I-multimeter ixhotyiswe ngemowudi ezenzekelayo eqaphela ngokuzenzekelayo uhlobo lwesignali yombane elinganiswayo, nokuba i-AC volts, i-volts ye-DC, ukuchasana, okanye ukuqhubeka.Oku kuphelisa imfuno yokukhethwa kwezandla kunye nokuqinisekisa ukufundwa ngokuchanekileyo kwamacandelo ahlukeneyo ombane.I-multimeter inomboniso ocacileyo we-LCD onamadijithi angama-6000 okulinganisa, ukubonelela ngeziphumo ezilula ukufunda.Ikwabandakanya isalathiso se-polarity, kunye nesimboli "-" ye-polarity engalunganga.Oku kuqinisekisa ukutolikwa ngokuchanekileyo kweziphumo zomlinganiselo.Ukuba umlinganiselo awukho kuluhlu, i-multimeter iya kubonisa "OL" okanye "-OL" ukubonisa ukugqithisa, ukuthintela ukufundwa kobuxoki.Ngexesha lesampulu ekhawulezayo malunga nemizuzwana eyi-0.4, ufumana iziphumo ezikhawulezayo nezichanekileyo zokusombulula ingxaki.

Ukugcina ubomi bebhetri, i-multimeter inomsebenzi wokuvala umbane ozenzekelayo osebenza emva kwemizuzu eyi-15 yokungasebenzi.Oku kunceda ekwandiseni ubomi bebhetri kwaye kukusindise ekubeni utshintshe rhoqo iibhetri.Ukongeza, uphawu lwebhetri ephantsi kwiscreen seLCD luyakukhumbuza xa ibhetri ifuna ukutshintshwa.I-multimeter inokumelana neendawo ezahlukeneyo kunye nomgangatho wokushisa osebenzayo we-0-40 ° C kunye nobubanzi bomswakama we-0-80% RH.Isenokugcinwa ngokukhuselekileyo kumaqondo obushushu e--10-60°C kunye namaqondo okufuma ukuya kwi-70%RH.Oku kuqinisekisa ukuqina kunye nokuthembeka naphantsi kweemeko ezinzima.I-multimeter isebenza kwiibhetri ezimbini ze-1.5V AAA ukunika amandla ahlala ixesha elide kwiimfuno zakho zokulinganisa.Uyilo olulula olunobunzima be-92 grams kuphela (ngaphandle kwebhetri) kunye nobukhulu obuncinci be-139.753.732.8 mm ukuze kube lula ukuthwala.Ii-multimeters zethu zifanelekile kubasebenzi bombane, abachwephesha kunye nee-hobbyists abafuna ukwenza imilinganiselo echanekileyo kwizinto ezahlukeneyo zombane.Iimpawu zayo ezisebenziseka lula kunye nokusebenza okuthembekileyo kuyenza ibe lulongezelelo oluxabisekileyo kwibhokisi yakho yezixhobo.
