Indlela ukukhetha multimeter ekhaya nemoto

Kuze emashumini ambalwa eminyaka edlule, inkosi, okwadingeka ukuba sisebenze ugesi, abakwazi ukucabanga ukuphila ngaphandle ezifana mishini ewusizo njengoba ohmmeter, voltmeter futhi ammeter. Namuhla beza esikhundleni imitha. Lesi sakamuva idivayisi jikelele ukuhlola ezihlukahlukene nemingcele kagesi kanye amanethiwekhi. Ake sizwe ukuthi ukukhetha multimeter ekhaya futhi imoto, cabangela injongo yalo mkhakha amadivayisi, ukusebenza kwabo.

Kuyini multimeter kulinganiswa?

angahlolwa ekusebenziseni le divayisi:

• DC futhi AC voltage;
• capacitance;
• izinga lokushisa ezingxenyeni ezahlukene circuit kagesi;
• ukusebenza transistors futhi diodes;
• inductance ohlobo;
• DC futhi AC zamanje.

izinhlobo multimeters

Ngaphambi wokuqonda indlela ukukhetha multimeter ezinhle, kudingeka ucabangele izinhlobo amadivaysi ezinjalo. Okwamanje kutholakala amakhosi ngogesi kanye namadivayisi analog. Cabangela izici zazo.

Ngo amadivayisi analog zonke izilinganiso iboniswe kubha ingcaca yokuhamba umcibisholo ngenhlonipho ekuhlukaniseni. Liqukethe Samandla, ngamunye elihambisana inkomba ethile. I ethile eyinhloko lesi simiso - the AMANGA isihlobo lobufakazi. Ngisho e qualitative analog multimeter umcibisholo kancane liyashintshashintsha ecaleni, okuholela enye idatha ukuhlanekezela. Ngokwemvelo, uma umninindlu okudinga ukulungiswa izindinganiso ezazivamile kuphela, futhi leli thuluzi zizongena kuso. Ngokuvamile, amadivayisi analog kuyinto cishe yisikhathi, ngakho asetshenziswa namuhla into evamile.

Umangele ngesibalo kanjani ukukhetha multimeter, izingcweti abanolwazi unake ngokuyinhloko amadivayisi ayi- elekhthroniki. Yonke idatha ekhiqizwa esibukweni digital. ukufundwa kuyaphindeka kuqondile futhi kulula ukuyiqonda. amadivaysi e-elekthronikhi izici nenzuzo kakhulu ukusebenza ebanzi.

Ukwakhela phezu kwasiphi amaphuzu kufanele uyinake uma uthenga multimeter?

Kunezindlela eziningana izici belinganisa ukuthi kufanele kubhekwe uma kukhethwa idivayisi sokulinganisa :

• ububanzi izinkomba;
• iphutha;
• kancane izilinganiso;
• kudivayisi sikagesi;
• inani display.

Ngokulandelako, cabangela indlela ukukhetha multimeter, ukugxila lezi nemingcele.

Ububanzi izinkomba

Izici yomkhiqizo ikhombisa esiphezulu kanye esincane umkhawulo amagugu nemingcele ukuthi kufanele kuhlaziywe. Ukukhethwa multimeter, kusukela uhla izinkomba, kuye ngokuthi ububanzi okuhloswe zedivayisi. Uma uhlela ukusebenzisa wona umsebenzi izimo zokuphila, kulesi simo ngokwanele ukuba ayeke ukukhetha kudivayisi ngobubanzi kuqhathaniswa nesizotha. Njengoba for izicelo ezimbonini, kukhona kangcono uthanda multimeter nge ehlukahlukene yasakazwa kungenzeka ipharamitha ngamunye kudingeka.

iphutha

Ngisho eliphezulu namadivayisi amaningi electronic ungavumeli ukuthola izilinganiso ngokuphelele eqondile. kunesithembiso Njalo iphutha elincane, yimaphi amadivayisi ahlukene ziyahlukahluka the uhla kusuka 0.02 kuya ku-3%. Nquma ukuthi ukukhetha umhloli-multimeter, kufanele zinikwe indawo ngokuthi ukuphambuka ekhona.

Uma idivayisi wokulinganisa kuthengwa ngomkhondo ukusebenza ngama-electronic, kutuswa ukuba banake onobuhle Iphutha elincane kakhulu. Njengoba ukusetshenziswa ezifuywayo umhloli, ngeke silingane idivayisi ne ukuphambuka ethile evela langempela ukusebenza nemingcele.

umthamo

Ingqikithi yalo wepharamitha, kanjani ukufundwa olunembile olungaphimiseka ekuskrini yokulinganisa kudivayisi. Ngokwesibonelo, ingxenye enkulu yomsebenzi multimeter kwansuku has 2.5-bit ekhombisa digital, ukubonisa amagugu kabani ukunemba ifinyelela izindawo kumakhulukhulu ledesimali. Ngesikhathi esifanayo, lo 3.5-bit amadivayisi okukhipha amagugu esikrinini ne thousandths.

Ukuzama ukuqonda ukuthi ukukhetha imitha, esekelwe kwemigomo ukudedelwa, kufanele ikhokhwe ukubaluleka amaphutha akhona. Uma iyamangalisa, ngisho kungenzeka thousandths of amagugu obala ngeke kunendaba, ngoba ulwazi kuyoba enganembile.

ukudla

Multimeters amadivayisi azimele wodwa. Eziningi zalezi imisebenzi kusukela amabhethri ezivamile. okuphakela amandla ngokuphelele ngokwanele ukuqinisekisa ukusebenza yesikhathi eside we umhloli, uma kunesidingo, enze izilinganiso yasendlini. Nokho, esimweni ukusebenza kwe-imitha nokuba angasetshenziswa ezimbonini ukuthi akwanele. Kulokhu-ke kubalulekile ukuba ayeke ukukhetha phezu umhloli, okuyinto ifakwe ibhethri capacitive.

Inombolo ekhombisa

Nakani kokwethula izici kufanele kube amakhosi, efuna of umhloli ukusetshenziswa endaweni yezimboni noma ngokusebenzisana Avionics eziyinkimbinkimbi. Khetha imoto multimeter wokulinganisa e evamile imvelo yasekhaya kungaba ukubonisa olulodwa. Ukuba izikrini amaningi digital kuyoba elula ochwepheshe abaku- duty kufanele baphathe wonke eningi izilinganiso ezahlukene.

Ukubuyekezwa kwe onobuhle ezithandwayo

Indlela ukukhetha multimeter semoto nekhaya? Kukhona izibonelo ezimbalwa ezivamile ngempela ukusebenza,-asebenziseka kalula abahloli afaneleka ngalezi zinhloso:

1. ADD8055 - Model multimeter eziklanyelwe yokulinganisa ukusebenza amabhethri. Nayo futhi lungangamela nemingcele yokusebenza lenjini ukuqalisa ikhompiyutha, thola idatha kwi-izingxenye ezihlukahlukene izifunda kagesi.
2. ADD280 - idivayisi ukusetshenziselwa ukuxilonga amabhlogo we kukhanya Imigudu e-diesel. Ukusebenza idivayisi kwenza kube nokwenzeka ukubona amaphutha isusa kumasistimu ezinjalo.
3. ADD3055 - umhloli inkinga ekutadisheni ahlukahlukene control inzwa amayunithi, izinhlelo kagesi izimoto. Ukubhebhetheka yasakazwa lokhu multimeter imodeli usezuze zosizo igxile ngoba esiza izimoto.
4. ADD8630 - ukuze kuhlolwe isimo lobuchwepheshe emotweni temusho, ugesi, amabhethri. Lokhu umhloli yakhiwa iyithimba e iphrinta, nge okuyinto kungenzeka ukubonisa ulwazi ephepheni.
5. ADD91 - Amatebhe wokulinganisa uhlelo ukuthi kabanzi Electricians nemoto Mechanics. Ubunjwe isibonisi ekhanyayo futhi uyakwazi belingisa amasignali lapho ukukhiqiza kabusha izinzwa ezihlukahlukene.

Amacebo eziwusizo

Ukuze ekugcineni unqume ukuthi ukhetha i-imitha semoto ukuqaliswa imisebenzi yasendlini kufanele bacabangele izincomo eziningana.

Lapho lapha iningi ngokuphelele yabahloli elekthronikhi asetshenziswa chips okuthembekile. Ngakho-ke, nakani ekhethekile idivayisi ukugcwaliswa ayidingekile. Kodwa ukubukeka idivayisi kubalulekile. Okokuqala kutuswa lokuhlola izinga inhlangano. Izingxenye we chassis kumele uxhumeke ngokuphephile. Wamukelwa ukuntuleka izikhala, izingxenye okuxekethile izingxenye zalo.

Indlela ukukhetha multimeter ukusetshenziswa ekhaya? Kulokhu, i plastic abavamile zizongena umhloli. Njengoba for ochwepheshe, lona wamuva kufanele ugxile ukuthengwa kudivayisi, ukugcwaliswa yangaphakathi okuyinto ebiyelwe ebiyelwe uphawu ukumelana. Lapho eqhuba multimeter izicelo zezimboni kungakuhle ukuthi idivayisi awuyiyivumeli emgodleni ngaphakathi uthuli futhi umswakama.

Nquma ukuthi iziphi imitha zokuphuma semoto nekhaya, sinake izindleko ukushintshwa. Uma lezi timphawu tesakhiwo zenziwa eliphansi le plastic, kungumqondo kwandisa amathuba ukuthi basuke ngendlela engenathemba babe okuxekethile ezinyangeni zokuqala wokusebenza zedivayisi. Ngenxa yalokho, ethungatha amamethrikhi kwesokudla kuyoba nzima kakhulu. Ngakho-ke kubalulekile ukuba makudle multimeters okunokwethenjelwa, okungcono metal ukushintshwa.

Ukuze uqonde ukuthi ukukhetha multimeter, okuyinto kuyoba usizo lusetshenziswa nsuku zonke, kudingeka baphendukele ukubeka ezinye onobuhle entendeni isithakazelo. Kungcono ukuba makudle idivayisi, okuzoba ukhululekile ukuba aqambe amanga esandleni.

amakhebuli ekhona kumele abe ezinhle cross-section. Kubalulekile lokhu ikakhulukazi ezimweni lapho kudingeka ukwenza izilinganiso amanani ezinkulu.

Kuyinto efiselekayo ukuthi ekupheleni probe icijiwe kahle. Esimweni esinjalo ngeke nhlobo izinkinga isidingo ukuvuma okwakufunwa contact amaphuzu owesincane wesifunda.

Ekuphetheni

Ngakho sabuka kanjani ukukhetha multimeter. Ekugcineni kuyafaneleka ukuthi, uma kudingeka, enze izilinganiso eziyisisekelo ezifana ngibheka kwebhethri noma zama-fuse, kungcono ukubheka kuqhathaniswa eziphansi abahloli. Uma izinhlelo zihlanganisa ukuqaliswa ngaphezulu izinkinga eziyinkimbinkimbi, kufanele ucabangele bathenga idivayisi Amatebhe ngempela.
