Yintoni na multimeters digital

Enye i zifundo ngokubanzi physics yaziwa, ukuba wesekethe ombane waphawulwa ngezinto eziliqela yemida. Phakathi kwabo, ixabiso ombane, okwabizwa ngokuba amandla ixabiso uhlobo olukhoyo ayahamba umqhubi, amandla ndiyaphela umthwalo kwi-network, ixabiso uxhathiso (in Ohms) kunye nabanye. Ukulinganisela into nganye kwezi zixhobo ezizodwa ziye zadalwa. Kuba oku ammeters yangoku, ombane -. Voltmeters, ohmmeters ukumelana, njl Noko ke, kuthekani ukuba kukho imfuneko yokuba umlinganiselo parameter ngaphezu kwesinye, kodwa eziliqela? Nxiba zonke izixhobo ezikhoyo kunye? Kule meko, ukuba sithetha yokuhamba kunye dhawo. izisombululo jikelele ziye wadalwa ukusombulula le ngxaki: izixhobo ezisebenza yokudibanisa kwabanye eziliqela. Umzekelo, tshintsha indawo yokuqala uneswitshi okhethekileyo, ungenza umlinganiselo ombane, kwi logic yesibini iyasebenza lwangaphakathi, nto leyo evumela ukugqiba uxhathiso. Kalula! izixhobo ezifana baziwa multimeters. Oko kukuthi "multi" - ezininzi, kakuhle, "m" - ngomlinganiselo. Isihloko yesibini, nto leyo kakhulu echanekileyo, - abahloli. multimeters digital Modern ukuvumela yalinganisa nobuninzi yemida ukusuka inxalenye ukumelana yesekethe elula lobushushu voice.

kokulungiswa

Nangona iyantlukwano enkulu zezi zixhobo, ukuba yahlulwe iindidi ezimbini eziphambili: analog multimeters digital. Kuba abasebenzisi abaninzi isebenze Okwesibini, nangona wokuqala zinezibonelelo ezininzi, ke, ezithile.

Isikali utolo iziqu

imodeli Analog iphantse ngaphandle imveliso, njengoko imfuno kwabo ezincinane, xa kuthelekiswa enye (Digital multimeter DT ngoku kakhulu ethandwayo). Nangona kunjalo, lo imarike kuyinto enokwenzeka nangoku ukuhlangabezana, izisombululo ezifanayo omtsha, ngoko ke ibikukujonga nje ngokufutshane kubo. izixhobo Analog Kulula kakhulu ukuba ukwahlula kwabanye emzimbeni yinto Ratchet yotshintsho yokukhetha indlela yokulinganisa, kwakunye ibhari enkulu kangangoko kunye isikali apho uphawu hlula (efanayo ukuya kumgca). Xa uqhagamshela uphenyo current wesiphaluka yenzeka jiko angaphakathi, amasimi Imagnethi uzikise kwaye intsebenziswano yazo kubangela utolo ebonisa baphambukile kwindawo engile ethile. Kuhleli kuphela ukuba zibale ixabiso yoqhekeko bafunde ixabiso parameter elilinganisiweyo. multimeters Digital kule nkalo akukhetha kakhulu ukusukela impazamo azibandakanywanga uguqulelo isikali nomgangatho ngezantsi umda ratchet ukubonwa.

Bonisa amanani

Digital Multimeters khangela phantse ngokufanayo analog, ngaphandle kokuba block isalathisi ithathwa screen compact, ebonisa iziphumo yomlinganiselo. utshintsho yangaphakathi, Kakade ke, kubaluleke kakhulu ngakumbi. Kwi ibhodi yesekethe ziprintwe obekwe chip ezisebenza inkqubo epheleleyo uphawu engenayo evela probe. Amaxesha amaninzi, izinto eziliqela ezongezelelweyo asetyenziswa - resistors, capacitors kunye jiko. Phakathi iimpawu ezikhethekileyo kwezi zigqibo, kubalulekile ukukhumbula ukuba minor isiphoso yomlinganiselo - high udidi yokuchaneka, imifuziselo ezingundoqo mali ewe, umzekelo, ezifana 838 multimeter lwedijithali.

UPawulos

Kuba umntu othi ngamanye amaxesha kukho imfuneko umlinganiselo ezinye Ipharamitha kwisekethe ekhaya okanye, umzekelo, inkqubo yombane isithuthi, zexabiso eliphantsi tester lwedijithali esingcono. Lwanele ukuqonda imithetho basebenzisa ratchet nokuqonda umgaqo ngokukhetha uluhlu womlinganiselo.
