I-Multimeter ibhekisela kumadivayisi angasiza kakhulu ekuphileni kwansuku zonke. Ngosizo lwabo, ungakwazi ukuxazulula imibuzo eminingi, isibonelo, indlela yokukala umthamo webhethri nge-multimeter? Ukuze usebenzise lokhu ngokusebenza, udinga ukunamathela ku-algorithm ethile yesenzo.
Inhloso ye-multimeter
Ngosizo lomhloli, awukwazi ukuhlola kuphela amandla amabhethri ane-multimeter, kodwa futhi namanye amasheke amaningi asebenzayo, phakathi kokuthi ungachaza okulandelayo:
- sesha ikhefu kwinethiwekhi yekhebula kagesi;
- ukucacisa ukubaluleka kwendiza emakethe;
- ukuzimisela kwenani lokumelana kwinethiwekhi;
- ukuhlola ukusebenza kahle kwemishini kagesi, kanye nama-light;
- kahle, futhi nenqubo eshiwo kakade, enikeza impendulo yombuzo, indlela yokuhlola amandla okubhethri nge-multimeter.
Ungenza kanjani ukuyeka?
Ukuze uqonde inkinga yokuhlola ikhono lebhethri elinomthamo we-multimeter, kuzodingeka izinyathelo eziningi. Isinyathelo sokuqala ukuvula idivayisi bese uyibeka ku-parameter "DC - Amperes". Okulandelayo, udinga ukulungisa izinkomba ezinconywayo zamapayipi:
- i-port value ye-probe enombolweni 1 kumele ibe yi-COM;
- isici sechweba se-probe ngenombolo 2 kufanele isethwe ku-10ADC;
- Isibambo kufanele sibe endaweni ebizwa nge-DAC noma i-DCA;
- Umphumela omkhulu wokuqinisekiswa akufanele ube ngaphansi kuka-6 A nangaphezulu kuka-10 A.
Kumele kukhunjulwe ukuthi ukusetshenziswa kwe "Volta" isikhundla ukuze kunqume amandla wamanje akuvumelekile. Manje sidinga ukuxhuma izinsimbi zomculo wokulinganisa koxhumana nabo, ngokusho kobudlelwane obulandelayo:
- Isiphetho se "+" sixhunywe ku- "+" ebhethri;
- Ngokufanele, ukugcina okungezansi kuxhunywe ohlangothini nge-polarity engafanele.
Ungesabi ukuthi le polarity izodideka. Kulesi simo, uphawu olubi kuphela luzovela ngaphambi kwenombolo. Uma uqhuba isilinganiso, kubalulekile ukuthi ungagudluli ngaphezulu-ukujikeleza kwesigodi, ngoba ukuphenduka okwenzekayo kungaholela ekuqothulweni kwebhethri entsha. Isikhathi esiphezulu senqubo akumele sidlule imizuzwana emibili. Lokhu kwanele ukubona ukubaluleka kwepharamitha e-ampere oyifunayo kumbukiso wokuhlola. Okufanelekile, konke kufanele kwabiwa okungaphezu kwesigamu esisodwa.
Imiphumela yokulinganisa
Ngokusekelwe kokutholiwe, kungenzeka ukudweba iziphetho mayelana nesiphambano esengeziwe sokusebenzisa ibhethri. Kubalulekile ukukhumbula kuphela ukuthi inani eliphakeme lepharamitha elifunayo, lizoba namandla kakhulu:
- ngakho-ke, isibonelo, ukulawula okukude kungasebenza kahle ngebhethri elinamandla wamanje we-1A. Kodwa ukuze kusebenze kahle ikhamera, kunesidingo esingaphezu kwe-5 A;
- Amandla wamanje akakafiki ngisho ne-A A - angasetshenziswa kuphela ekusebenzeni kwezinto zikagesi ezidla inani elingenakubalwa lamandla. Amadivaysi anjalo yi-radio encane ye-pocket noma iwashi lesodonga.
Indlela enhle kunazo zonke yokuhlola ukufaneleka kwebhethri ukuwufaka kumshini kagesi. Ngemuva kokulinganisa ipharamitha, akudingekile ukulahleka kolwazi oluboniswa ngqo ebhethri. Ngokuvamile, ayibhalisi ukufakwa kwamandla, kodwa i-voltage yomthamo noma ngamanye amazwi ukungezwani. Ezimweni eziningi, imingcele elandelayo ichaziwe:
- 1.5 V - kuboniswe amabhethri amasha (alahlwa) amasha;
- 1.2 V - okuyinto iselibhethri inikeza.
Ukulandela i-algorithm ethile yezenzo, ungakwazi ukukala umthamo webhethri usebenzisa i-multimeter. Lokhu kuzosiza ukunquma ukuthi iyiphi idivayisi okufanele ukuyisebenzise.
