Pointer multimeter yuav ua li cas kuaj lub horn zoo los yog phem
Pointer multimeter yuav ua li cas txhawm rau ntsuas horn zoo lossis phem rau pointer multimeter hu rau ohm cov ntaub ntawv, thiab tom qab ntawd hu rau lub multimeter mus rau ib ohm, random pointer multimeter, cwj mem liab, cwj mem dub luv rau xoom, kom qhov ntsuas qhov tseeb, ntsuas ntawm lub horn tsis xav tau cov lus nyhuv, ncaj qha mus rau lub multimeter hloov mus rau ib ohm, lub rooj cwj mem casually caij mus rau ib tug zoo, tsis zoo ncej ntawm ib tug horn yuav siv tau casually nrog rau lwm tus cwj mem kov lub horn lwm ncej, tsuav yog hnov lub suab ntawm nias, ua pov thawj tias tus hais lus zoo, ntawm qhov tsis sib xws, tsis muaj suab, ua pov thawj tias nws tsis zoo. Cov saum toj no yog ib tug pointer multimeter los txiav txim tus hais lus zoo phem phem ntsuas txoj kev, txiav txim tus hais lus yog zoo los yog phem, nrog ib tug pointer multimeter ib ohm cov ntaub ntawv, qhov zoo tshaj plaws ntsuas.
Kev soj ntsuam ntawm lub horn siv cov ntaub ntawv tshawb nrhiav tsis kam yog, lub horn yog tsav los ntawm tooj liab hlau winding kuj coil, raws li impedance yuav tsum tau muab faib ua 4 ohms, 8 ohms, thiab lwm yam, tsuav yog tam sim no los ntawm zoo. Qhov no yog qhov kev paub tau kawm 55 xyoo dhau los, thaum lawv sib sau ua ke lawv tus kheej xya-tube transistor semiconductor xov tooj cua, kho transistor TV. Tam sim no nws yog tag nrho cov chips sib xyaw ua ke, thiab cov kev paub tau hloov kho, tab sis cov ntsiab lus ntawm lub horn tsis tau hloov ntau.
