Indlela ukukhangela amps multimeter? umyalelo

Multimeter ebizwa obusisixhobo esiza kusetyenziswa umlinganiso ombane, ngoku, ukumelana, wenziwa "ukuqhubekeka" of macingo. Oko kukuthi, le divaysi enesidingo. Ke kaloku, njengokuba kusenziwa zibonisa, onobuhlobo ethandwayo kwanele nje kuphela kushishino kodwa kubomi bemihla ngemihla.

Kodwa ngaphambi kokuba uqale, umlinganiselo, kufanele kuqatshelwe ukuba multimeter - isixhobo ngqo engeyongozi. Xa lisetyenziswe ngendlela engafanelekanga, hayi nje ngokulula ungayikhubaza, kodwa inokubangela umonakalo omkhulu kwimpilo yakho. Oku kuyinyaniso ngakumbi kwiimeko apho ufuna ukwenza imilinganiselo kwi ombane aphezulu okanye kul eliphezulu. Awunako nje ngomlilo nangoko imitha, kodwa kwakhona ukufumana wothuka kakhulu zombane.

Kungenxa yoko le nto, ngaphambi kokuba uqale ukusebenzisa imitha, kufuneka aqeqeshwe kubonelelo amandla kunye nokusebenza eliphantsi ngoku, ezifana ibhetri. Kufuneka kwakhona ngoyaba umyalelo kwifowuni.

imihlobo multimeters

Okokuqala, ufanele wazi ukuba multimeters digital kunye analog (utolo, nditsho phakathi ngombane, aziwa njengoku "tseshka"). zikagesi Second baziwa ixesha elide, kodwa ukusebenzisa ngaphandle naluphi na ulwazi olukhethekileyo kunye neenkqubo kunzima.

• kufuneka bakwazi ukuqonda isikali isixhobo, apho kwisiliphu multimeter bambalwa;
• isixhobo kufuneka kubanjelwa meko, xa kungekho utolo kuyo ukuba "ukuhamba" kwi esikalini.

Kungenxa yoko le nto, ukuba kukho ithuba enjalo, kubhetele ukuba kusetyenziswe multimeter yedijithali. Kwakhona siza kuqwalasela imizekelo usebenzisa nje isixhobo i-digital njengokuba wena ufunda ukusebenza nzima kunye multimeters analog.

Kwiintlobo ngeentlobo yedijithali multimeters ngokwaneleyo, kodwa isebenza njani kuyafana omnye komnye - umahluko kuphela inani iifowuni. Ngako oko, ukusuka ukusebenza multimeter kunye ixabiso ixhomekeke, ngoko phambi kokuba yithenge, isigqibo yintoni na oyifunayo.

Imitha siquka:

• idivayisi uqobo;
• ixhokonxa ezimbini (ezimnyama);
• umthombo wamandla (ibhetri "Crown" 9B).

Ngoko ke, ziziphi iimpawu nokusetyenziswa kwesixhobo sokulinganisa nendlela ukukhangela amps multimeter?

umyalelo

Ukuze umlinganiselo wangoku kwisekethe, kuyimfuneko nangendlela ecwangciswe kakuhle ngokulandelelana ukwazi ukuqhagamshela ifowuni kuso. Ngelo xesha kwi multimeter kuyimfuneko ukuba liphande ebomvu ukuya kwisokethi obusisixhobo ma enombhalo, namnyama - in com. uqhagamshelo Uthotho kuthetha ukuba chain kufuneka eyaphukileyo probe ngasinye incanyathiselwe ucingo eyahlukileyo, t. E. I sixhobo kufuneka adityaniswe phakathi imithombo ezimbini ngamandla. Kodwa njengoko umlinganiselo inqaba ngoku, kwaye amandla okwenza oko nje ukuba imithombo akwenzeki, kufuneka ukuba ibe nomxokelelwane ethile sixhobo, ezifana ibhalbhu eqhelekileyo, uyibeka kwisekethe ngoko nangoko emva umthombo wamandla.

Ukuba Wayilinganisa AC amandla, ifowuni kuzakucwangcisa xabiso liphezulu le-AC (isimboli A ~ - qaphela ukuba efana kakhulu kwi icon DC (A), ngoko ke lumka). Yaye kuphela emva kokuba ukuba ungakwazi ukuqala imilinganiselo.

Phambi kokuba ukhangela ampere multimeter, qiniseka ukuba amandla ngoku elilinganisiweyo yi eziphakamileyo kakhulu, okt. A., imilinganiselo ezinjalo ukuze ukhuseleke ngenxa icandelo encinane umnqamlezo macingo probe. Le yokugqibela akakwazi ukumelana imithwalo eziphakamileyo. Iingcali Siyaleza ukuqhuba imilinganiselo kwi ixabiso langoku 10 A ikliphu-on.

Hlola multimeter ibhetri

Iitsheki kufuneka wenziwe kuphela phantsi komthwalo. Khangela amperes ezininzi kangakanani ibhetri multimeter kuphela ngokusebenzisa amandla ibhetri lwangaphakathi akwenzeki ngenxa yokuba ixabiso layo liphantsi - manani ngenxa musa zichaza amanani oyinyaniso.

Tester sokukala nje kuphela ngoku yokusebenza, kodwa ke ukuvuza yangoku ibhetri. Phambi kokuba ukhangela multimeter wakho amperes of ukuvuza lwangoku, kufuneka ukhumbule ukuba ibe ukuya amperes eziliqela. Ngoko wabeka phezu uluhlu womlinganiselo esixhobo kufuneka ngokuchanekileyo, kungcono 10 A.

Ekusebenzeni phambi kokuba uvavanyo phaya kwibhetri amps multimeter uphakanyiselwa kunye iiterminal ze battery ye ibhetri intambo kakuhle ukubandakanya kwifowni isiphumo yokulinganisa msantsa. Emva koko ke kufuneka:

• khetha imo kwi multimeter yokulinganisa ngoku;
• ukulungisa "ingwenya 'ucingo khosi kume iifyuzi, athi abenoxanduva lomnqongo electronic kwisithuthi.

Ngenxa yokusebenza ethile, uya kuyazi kuphela ukuba batshekishe indlela amps multimeter, kodwa unako lula ukubona unobangela evuzayo, ngaphandle kokubhenela kwiziko lenkonzo.

itshaja Ihlola

Ngaphambi kokuba siphendule lo mbuzo: "Indlela ukukhangela amps multimeter kwitshaja," kufuneka uyazi ukuba ungakwazi ulinganise, umgaqo, nayiphi na Ukuvuya womserbia. Kunokuba ibe kwifowuni okanye tablet, itshaja ibhetri imoto, njalo-njalo. D.

phone Charger

imilinganiselo enjalo aphela rhoqo efunekayo xa kuyimfuneko ukuchonga unobangela memory nandzu. Kufuneka kuqatshelwe ukuba amandla ezikhoyo tshaja yefowuni, amacwecwe njalo njalo. E. Ukuxhasa kancinane ulawulo ezahlukeneyo kwaye idla kuboniswe kwileyibhile itshaja okanye zokumakisha. Kodwa ke ukuba akukho ileyibhile enjalo, ngenxa yaso nasiphi na isizathu, ngoko ungakwazi ukukhangela le multimeter nani.

Umgaqo yokulinganisa ngoku kwitshaja ezingafaniyo kuphela kukuba kunzima ukudibanisa kuwo ixhokonxa multimeter ngenxa ubukhulu encinane abafowunelwa kwi isinxibelelanisi. Ukuza kuthi ga ngoku, abafowunelwa kufuneka ifakwe ngononophelo abaqhelekileyo yokuthunga steel inaliti kunye nayo ukuqhagamshela kuphando multimeter. Ukuba bobabini musa, ngoko ke abanaluncedo kuphela nokuxhuzulwa ukuvulwa lwezindlu ukudibanisa ixhokonxa ngqo kwimemori kwiitheminali kwindawo apho iphela na soldered intambo yombane.

Charger ukuba ibhetri yemoto

Ngaphambi kokuba sithethe ngayo ukuba batshekishe indlela amps kwitshaja multimeter ukuba ibhetri yemoto, kufuneka ukuba uyazi, lenza ntoni.

Ixabiso eliphezulu kokuxhuzulwa sangoku imemori-10% besikhundla kwebhetri imoto. Ixabiso elikhulu ikuvumela ngokukhawuleza kwakhona ibhetri, kodwa embi kuya kuchaphazela ibhetri ngokwayo, kwaye ziyakwehlisa ngokubonakalayo ixesha lokusetyenziswa kwayo.

Xa uthenga memory enjalo ukugcina zonke iparameters ezibhaliweyo kwitshaja. Kodwa umyalelo onjalo, ulwazi oluncinane kungenziwa ngokuzimeleyo. Kulo mzekelo uthe weza multimeter lokuposa. Kwakhona, le imitha kuluncedo ukuba imemori lutshitshe.

Kufuneka ke ukuba xa yokulinganisa kul nayiphi tshaja kwisekethe kufuneka sibandakanye nasiphi na umthwalo (umz, i ibhalbhu ilayite eziqhelekileyo). Kwakhona, musa ukulibala ukuba imemori kudla ibonelela ngoku rhoqo, ngoko ke usiba imitha kufuneka zaziswe indawo efanele (A).

Khangela unikezelo lwamandla

Indlela ukukhangela amps multimeter kwi umbane? Oku kwenziwa kuba umthamo eqine kufuneka ukuyisebenzisa. Umgaqo lulodwa eyahlukileyo kakhulu ngokujonga neminye imithombo. Kuyimfuneko kuphela ukuba uqaphele ukuba PSU ngaba inobunzima kunokuba enkulu, ngoko imilinganiselo kufuneka wenziwe nophando, ngaphandle ixhokonxa ukufudumeza iingcingo multimeter.

Njengoko ubona, imitha kunokuba luncedo kakhulu kubomi bemihla ngemihla ezifunwayo kwiindawo ezahlukeneyo ngokupheleleyo, ngoko ke akuyi kuba akufuneki ukufumana ulwazi kakhulu amancinane ukusetyenziswa kwayo.
