Indlela hlola voltage esidayisa multimeter jikelele

Ugesi endlini - into evamile. Aqala ukudliwa yiwo wonke. Wonke umuntu uyazi ukuthi inethiwekhi zinamandla 220 V futhi wonke nemishini zenzelwe lo voltage. Kodwa azivamile ubheka imfundo lapho umenzi kubonisa ukuphambuka ovumelekile kusukela voltage okuzisholo lapho umshini othile angase isebenze ngaphandle umonakalo busebenze yayo. Iwashi namanje kunomvuzo, ikakhulukazi ukubakhulisa babe isiqiniseko sokuba njalo ekhona 220 V

Eqinisweni, ukucindezeleka kushintsha njalo, yebo, uma indlu akanayo stabilizers ekhethekile agudle zonke kuzuba, oqaphe ngokucophelela imishini. Ngo esiku amandla esidayisa kungabonakala nasemkhakheni, no-180, futhi 270 B. Akubona bonke imishini ukujamelana isimo sengqondo ezinzima.

Yini ukuthatha bazivikele ingozi nokulahlekelwa electronics? Okokuqala, kubalulekile ukuba sigqoke zonke okokufaka wokusabalalisa inkinobho ibhokisi iyunithi cutoff ka voltage high, okuyizinto ayatholakala emakhemisi. Okwesibili, ukuthenga i multimeter electronic. Indlela hlola multimeter esidayisa voltage? Mayelana-ke - ngezansi.

Ukulinganisa Kudivayisi: izinhlobo

amadivaysi kagesi ezibhekwa, ezisetshenziswa for nesilinganiso ngobuningi kagesi. Lamagugu ukusebenzisa amandla zamanje, voltage kanye ukumelana. Ukuze uhlobo nesilinganiso ngayinye kusetshenziswa uhlobo oluthile divayisi, kodwa kukhona inqubo enemisebenzi evumela ukukala nemingcele ezahlukene ugesi.

Ngokusho uhlobo ukusebenza sekunezifunda analog amadivayisi obuchwepheshe. Analog kube inkomba yokuthi ukubaluleka ipharamitha kokuba kulinganiswa usebenzisa indlela nge umcibisholo kanye esikalini iziqu. Esikhathini samanje digital ukubonisa electronic, okuyinto ubonisa yi nesilinganiso.

Wonke amayunithi abe nezici ezilandelayo esemqoka:

• Ukuzwela.
• Iphutha Ukumeda.

Ngo-semi lezi nemingcele nezanele ukuba ulinganise multimeter voltage kwayo kuleyo ndawo yokuhweba.

Yikuphi imingcele lingalinganiswa ngumuntu multimeter

Multimeters ezihlobene kumadivayisi isicelo jikelele. Bangenza yizilinganiso wamanje kanye voltage prozvanivat uchungechunge isheke Semiconductor amadivayisi eqondile kushintshana ukunquma ubukhulu capacitance. Ibanga wokulinganisa idivayisi inkinobho ngamaviyo eziningana. Nge inqubo enjalo akuyona kuphakama umbuzo: kanjani ukuhlola voltage kwayo kuleyo ndawo yokuhweba odongeni? Multimeter Kulula kakhulu ukuyisebenzisa.

Kukhona amacebo analog electronic. izilinganiso Analog ngayinye zilwane abe isikali yayo nge iziqu. Ngesikhathi imikhawulo yalesi isici, okuyilona elidingekayo ukuze wande inombolo etholakale lapho kulinganiswa ukuze unombono yenani wangempela ipharamitha kulinganiswa. Electronic kulula, ngoba ayidingi izinyathelo ezengeziwe - ku iBhodi ngokushesha ubonisa yi. Ungakwazi kalula hlola multimeter voltage kwayo kuleyo ndawo yokuhweba.

izakhi Functional multimeter

multimeters Iningi ekhiqizwa, engatholwa emakethe, eyenzelwe anhlobonhlobo abathengi. Sinenkosi umklamo ejwayelekile nge ilungiselelo izilawuli.

Ngaphambili iphaneli has a ububanzi okucaciswe luketshezi (LCD) isiboniso, esiyindilinga inkinobho ezahlukeneyo imingcele elinganisiwe futhi yabo imikhawulo, abathathu uxhumano ngoba uphenyo kudivayisi, Isixhumi for nesilinganiso kwemigomo transistors. Umdwebo wokuhlelwa kwendikimba ithuluzi kunikwe amandla "Umqhele" uhlobo ibhethri 9 V

inkinobho izikhundla Ukumaka uthi lokhu okulandelayo:

• OFF - idivayisi ongasebenzi;
• DCV - DC nesilinganiso mode;
• DCA - DC nesilinganiso mode;
• ACV - AC nesilinganiso mode;
• hFE - kuhlolwa transistors;
• ●))) - proring wesifunda kagesi noma diodes;
• Ω - yokukala ukubaluleka ukumelana.

Indlela hlola multimeter esidayisa voltage

Ukuze wenze noma yimuphi izilinganiso, kubalulekile kuqala kuzo zonke ukuxhuma kwi-iphenya kudivayisi. Ziyakwazi ngokuvamile yemibala emibili - elibomvu, omunye abamnyama. Black, njengoba umthetho, kuba zero, jikelele noma lokususa uphenyo, ngakho-ke ixhunywe ku-ukuphela aphansi esinelebuli COM. Okwesibili, obomvu, cishe zonke izilinganiso uxhumeke kwi-maphakathi. Isixhumi engenhla iwukuba Uphenyo elibomvu lapho kulinganiswa AC zamanje afika ku-10 A.

Okulandelayo, khetha imodi ngokuvula round inkinobho kwindawo oyifunayo. Uma eyaziwa ngalo elaziwayo kufanele ipharamitha kulinganiswa, umkhawulo nesilinganiso embukisweni kancane ezinkulu. Lokhu kwenziwa ukuze ashise kudivayisi. Kodwa kungase kube nesimo lapho kungekho isiphakamiso idivayisi ongabonisa. Khona-ke kumkhawulo nesilinganiso abonise okunokwenzeka enkulu.

Ngemva kwalokho, zihlanganisa idivayisi lapha. Uma voltage elinganisiwe, parallel uma wamanje - ngokulandelana. Ukumelana nesilinganiso nomai Semiconductors wenziwa ukungabi ukudla circuit nesilinganiso. Ngaphezu kwalokho thatha ukufundwa.

Ngenxa multimeter ukuhlola voltage ku 220V? Humushela inkinobho ukuze kukhawulwe ACV 750 bese metering wenziwa. Ngenxa multimeter ukuhlola lo voltage in inethiwekhi 380V? Ngendlela efanayo. Kumele kukhunjulwe ukuthi lesi ugesi kuyingozi empilweni, futhi qaphela.

Kanjani ukuhlola ukungabi khona kudivayisi inethiwekhi

Uma imitha ayitholakali, futhi esiphuthumayo ukuhlola ukuthi kukhona amandla izisekelo, ungasebenzisa wesifunda elula. Thatha abavamile esikhipha isibani 220 futhi cap (kuzingxenye threaded) ucezu ngokuqinile screwed tape metal noma induku zethusi ububanzi ezingekho ngaphezu 4 mm. Rod ngensimbi ekupheleni, futhi ezinye contact isibani soldered balahleke wire ukwahlukanisa. Umphumela waba osampulako. Voltage kubo, yebo, akachaziwe, kodwa khona ugesi kungenziwa isethwe. Ungahlola ngisho ukutholakala isigaba, uma kukhona emhlabathini omuhle, kwaziwa ukuthi wamanje kungaba flow phakathi isigaba nomhlaba, ngaphandle kokudinga zero inethiwekhi izintambo. Kodwa le ndlela kufanelekile ngaphezulu abanolwazi Electricians.

isiphetho

Uma kuseyinkinga, indlela ukuhlola multimeter esidayisa voltage, imiyalelo inikezwe kudivayisi lencazelo eningiliziwe. Ngiyajabula ukuthi lezi amadivaysi abe ngentengo ephansi.
