I-Multimeter ibhekisela kumadivayisi anokunceda kakhulu ubomi bemihla ngemihla. Ngoncedo lwabo, unokuyicombulula imibuzo emininzi, umzekelo, indlela yokulinganisa umbane webhethri ene-multimeter? Ukuze uzalisekise oku kusebenza, kufuneka uhambelane ne-algorithm ethile yesenzo.
Injongo yemimitha-mitha
Ngokuncedwa ngumhloli, awukwazi nje ukukhangela amandla amabhetri anemimitha-mitha, kodwa kunye nezinye iindawo zokuhlola ezifanelekileyo, apho ungakhetha khona oku:
- khangela ikhefu kumnatha wekhebula kagesi;
- ukugqiba ukubaluleka kombane kwiziseko;
- ukuzimisela kwexabiso lokumelana nenethiwekhi;
- ukujonga ukusetyenziswa kwezinto zombane, kunye namabala okukhanya;
- kakuhle, kunye nenkqubo ekhankanywe ngaphambili, ukunika impendulo kumbuzo, indlela yokujonga umbane webhethri ene-multimeter.
Ungenza njani ukuyeka?
Ukuze uqonde ingxaki yokujonga ubungakanani bebhethri ene-multimeter, kuya kufuneka. Isinyathelo sokuqala ukuvula ifowuni kwaye uyibeke kwi parameter "DC - Amperes". Emva koko, kufuneka uqulunqe izikhombisi ezicetyiswayo kumachweba:
- Ixabiso lesipoti leprobe kwi-number 1 kufuneka ibe yi-COM;
- uphawu lwesipoti seprobe kwinqanaba 2 kufuneka lisetwe kwi-10ADC;
- Isibambo kufuneka sibe kwindawo ebizwa ngokuthi iDAC okanye i-DCA;
- Isiphumo esiphezulu sokuqinisekisa akufanele sibe ngaphantsi kwe-6 A nangaphezulu kwe-10 A.
Kufuneka ukhunjulwe ukuba ukusetyenziswa kwe "Volta" isikhundla sokuba kuqinisekiswe amandla okwangoku akuvumelekanga. Ngoku sifuna ukudibanisa izixhobo zesilinganisi sokulinganisa kubafowunelwa, ngokuhambelana nolu hlobo lulandelayo:
- Isixhobo "+" sixhunywe kwi "+" kwibhetri;
- ngokufanelekileyo, isistim sokugcina sinxibeleleneyo kwicala kunye nenkunkuma engalunganga.
Ungesabi ukuba i-polarity iya kudideka. Kule meko, kuphela uphawu olubi oluya kubonakala phambi kwenani. Xa uqhuba imilinganiselo, kubalulekile ukuba ungagqithisi ngaphezu kwesiphaluli esivaliweyo, ngenxa yokuba iimeko ezinjalo zingabangela ukutshabalaliswa kwebhetri entsha. Isixa esiphezulu senkqubo asifanele sidlule imizuzwana emibini. Oku kwaneleyo ukubona ixabiso le parameter elifunayo kwi-test tester. Ngokufanelekileyo, yonke into ayifanele ibekwe ngaphaya kweyesibini.
Iziphumo zemitha
Ngokusekelwe kwiimfuno ezifunyenweyo, kunokwenzeka ukufumana izigqibo malunga nesiphumo esongezelelweyo sokusebenzisa ibhetri. Kufanelekile ukukhumbula kuphela ukuba ixabiso eliphakamileyo leparameter elifunayo, liza kusebenza ngakumbi:
- Ngoko, umzekelo, ukulawula okukude kunokusebenza kakuhle ngebhetri enegunya langoku le-1A. Kodwa ngokusebenza ngokufanelekileyo kwekhamera, kukho uphawu olungaphezu kwe-5 A olufunekayo;
- Amandla angoku ayifumanekanga nakwi-A A-ingasetyenziswa kuphela ekusebenziseni izixhobo zombane ezidla inani elingenamlinganiselo wamandla. Iifowuni ezinjalo i-radiyo encinci yesikhwama okanye iwashi yokudonga.
Indlela efanelekileyo kakhulu yokujonga ukufaneleka kobugcisa bhetri ukuyifaka kwisixhobo sombane. Emva kokulinganisa iparameter, akuyimfuneko ukulahleka ulwazi oluboniswe ngqo kwibhetri. Ngokuqhelekileyo, ayibhalisi i-amperage, kodwa i-voltage nomninimandla okanye ngamanye amagama ukutshatyalaliswa. Kwiimeko ezininzi, iiparameters ezilandelayo zichazwe:
- 1.5 V - kuboniswe kwiibhetri ezintsha (ezilahlayo);
- 1.2 V - leyo iseli yebhetri inika.
Ukulandela i-algorithm ethile yezenzo, unokulinganisela amandla ebhetri usebenzisa i-multimeter. Oku kuya kukunceda ukuba yeyiphi idivaysi ukusebenzisa.
