Measuring Nozenza izifinyiso leligama iintlobo. izixhobo zombane

iziganeko Electrical ngokuyimfuneko kuqhubeka phakathi sikhokelo yokwakha kunye nokuhlaziywa. Ukongeza, iindlela zabo zisetyenziswa kwezinye kumashishini kunye nokuvavanywa izinto. licandelo elinyanzelekileyo yokugcina naziphi na zombane zizixhobo zombane ukuba kuzakuvumela uku chaza iimpawu kumgca elithile lomsebenzi.

ulwazi ngokubanzi malunga zobunjineli yombane

Izixhobo Inkoliso yale eklasini lujolise ngokuchonga engundoqo parameters amathathu - ngoku, ombane kunye ukuxhathisa. Kulo mzekelo, kukho izixhobo ezikuvumela ukuba ukufumanisa iimpawu nje ezintathu, kodwa kukho isixhobo ezizodwa eyenzelwe ukuchonga Iimpawu ezithile. Kodwa zonke zixhobo ezahlukeneyo imeko enye ebalulekileyo umsebenzi - nje waphule musa bayasigqwetha umgca okhoyo. Ngokukodwa, ezi pincers umlinganiselo ekwaziyo bokulungisa enkulu amaxabiso amandla nemisinga ngaphandle ngokwaphula wesekethe. Nangona kunjalo, kukho abantu abayimizekelo indawo yolu hlobo kuneengxaki ezibalulekileyo. Okokuqala, abaqinisekanga ngokuqhelekileyo kakuhle kakhulu. Kwanele ukuba athi ukuba sizimisele umgangatho parameter kuxhomekeke indawo iindawo abasebenza kuzo ifowuni. Okwesibini, ukuba data ngaphezulu okanye ngaphantsi injongo kufuna ezinye uqeqesho kunye umsebenzisi.

Kwezinye iimeko, kusetyenziswa nezifinyiso yokulinganisa?

Thina amakhalane intsimi kakhulu ezithile isicelo. Isibakala sokuba izixhobo zobungcali uvavanyo kakhulu ezifanelekileyo ngaphakathi kunye kwisiza yokwakha, apho kukho zonke iimeko umsebenzi bekhululekile. Ngenxa yoko, ezi ntwala zigxile ngakumbi umsebenzi kwiindawo ezinzima, ukuquka imigca yomphakamo-ombane. Ibiya kuthetha ukuba umsebenzi kwiindawo ezibuthathaka akufunekanga ibe sisixhobo nje hlobo. Kodwa ngqo yokugcina kwiipropati zokusebenza ezaneleyo, umzekelo, ukulinganisa ezi ntwala DC yongezwe izixhobo ezincedisayo. Ngoko ke, ukuba wemilinganiso yenziwe kumgca eliphezulu-ombane efanayo, apho kuya kubakho nto imbi ukongeza ukusebenzisa imisebenzi multimeter. Kukhethwa inikwa wayifanisa yedijithali - baya ukusebenza ngokuchanekileyo ngakumbi kwaye amakhalane kuba lula ngakumbi processing elandelayo kunye nobhaliso.

Types of ngeetikhi yokulinganisa

Kukho ezintathu umgaqo yokuzahlula ngokulinganisa iintlobo nemalanana. Ukuhlelwa Basic inika izixhobo segmentation ngokungqinelana uhlobo ixabiso elilinganiselweyo. Ngokukodwa, ezi izixhobo zombane angamelwa wattmeters, ohmmeter kunye phasemeter t. D. Kakade ke, kukho kwakhona imizekelo ubhetyebhetye eyenzelwe yokuphatha variables eziliqela ngaxeshanye, kodwa ukuchaneka ngokwemilinganiso enjalo idla ngaphantsi isixhobo ezizodwa.

Eyesibini sinxulumene kokwahlulwa uphumezo constructional. Ngenxa yesi sizathu le modeli yahlulwe igobhogobho lwedijithali kunye unpackaged. Okubaluleke ngokulinganayo indlela transfer data - le yindlela yokuhlela wesithathu. Umzekelo, izixhobo ezininzi ukuphumeza losasazo ngedatha ngamajelo analog. Kodwa kukho ukwanda kunye iifowuni ezisebenza ngaphandle kweengcingo. Ezi ziquka uqinisa Iphiko laliziimitha ukuguqulwa CNX 3000. Lo matshini na sidityaniswe kwi multimeter okanye kwi laptop yakho, esebenzisa amaqhoshana ezizodwa.

Iimpawu isixhobo

The main iparameters ezibonakalisa ukusebenza izixhobo yokulinganisa, zisekelwe kwixabiso eliphezulu uzimisele ziinqobo. Hi xikombiso, le ombane ubuninzi kwi iimodeli ezisemgangathweni ongowona 600 V. iyawulwa ukhetho efanayo kuya kuba uluhlu 20-40 ohms. Ngaphezu koko, kubalulekile ukuba uthathe ingqalelo into yokuba ukungaqiniseki. izixhobo zobungcali kule klasi Ngokuqhelekileyo abe ixabiso ubuncinane ezinxaxhileyo - zomyalelo-1%. yokulinganisa Household Nozenza izifinyiso ukwenza imilinganiselo kunye imposiso avareji malunga ne-2%. Kwakhona, xa ukhetha i isixhobo Ukuzibona lombane kuyimfuneko ukunikela ingqalelo kwezinye, ergonomic iparameters. Xa kuziwa isixhobo yedijithali, ngoko, umzekelo, akuyi kuba akufuneki ukuvavanya ukusebenza izakhono interface, Isibonisi, kunye nonxibelelwano.

abenzi

imifuziselo ezisebenzayo zobugcisa amakhalane kukhona emakethe brand Elitech ekhankanywe inkampani Iphiko, Sturm kunye nabanye. Ezi zoomatshini banamhlanje ezikuvumela ukuba ukwakha inyanda oxineneyo lonxibelelwano ngeekhompyutha kunye multimeters. Ababhekisi phambili bacinge kunye neemodeli yokusebenza yoyilo ngokwemiqathango zokunciphisa uphazamiseko, yaye ukuphatha ergonomics konke ifowuni. imifuziselo Okuninzi zemveli enziwe kwakhona ziinkampani zasekhaya, phakathi kuyo "Bison" yaye "Resanta". Ngokuqhelekileyo, le ntwala Dietze kunye kuyilo classical base yokusebenza ukumelana womlinganiselo, ngoku kunye ombane. Oku akuthethi ukuba izixhobo Russian ungaphinda balahlekelwe iimveliso angaphandle processability. version Budget ngokwenene khangela nje kwi imvelaphi kwezixhobo premium Elitech okanye Iphiko, kodwa kwezinye iintsapho uhlobo olufanayo "Zubr" ubuchule kunye nezisombululo mihla ekuphunyezweni ezisebenzayo kunye noshowo lwezindlu.

Ixabiso udaba

Kwakhona, umahluko isiseko ixabiso ingakumbi Yarkov wazilanda xa bethelekisa imveliso Russian angaphandle. Xa umgca kwiinkampani zasekhaya lwabiwo-ngokwenza Ungafumana imodeli 1-2 amawaka. Thambisani. izixhobo ezingcono, ezinokuthi zisetyenziswe ekusombululeni iingxaki zobungcali, kuqikelelwa kwi 3-4 amawaka. Thambisani. Hi ndlela leyi, kuluhlu efanayo iindleko ephantsi izifinyiso umlinganiselo amazwe. Ixabiso kwezixhobo lobuchwepheshe Iphiko okanye Sturm unako ukufikelela amawaka 6-7. Le iteknoloji engenazingcingo enye, nto leyo ebonakala ichanile aphezulu zomlinganiselo, kwaye ihlala inqanaba.

isiphelo

Xa ukhetho kwezixhobo yokulinganisa kubalulekile ukuhlola iimfuneko ngokusebenza ekucwangciselwa yena. weefomati owahlukileyo kakhulu yokusebenza ezinjalo izixhobo, ngoko ke parameters ukhetho ziyahluka kakhulu. Ngoko ke, ngenxa yomsebenzi yonyaka kumgca ikhaya kwindawo nkonzo ozimeleyo, isixhobo yokulinganisa kunye noyilo olusisiseko, ukubonelelwa analog lwe data kunye neendleko ukuya ku-2 lamawaka. Ngokuba inkosi lowo idla langutane umsebenzi odingekayo isigqibo imisebenzi yokulinganisa hlobo, kuyimfuneko ukubonelela ngomatshini ngakumbi kakhulu . Oku kungaba imodeli kunye ithegi ngexabiso eliyi-4 th., Nguwuphi kuvumela umsebenzisi ukuba ukuhlangana ngezixhobo abangabancedani. Loo ngobuwena kangangoko ngokwemiqathango zemilinganiselo ukuchana, kwaye yokusebenza kunye ergonomics malunga ukusebenzisa le mveliso.
