VU meters tau xub tsim los rau ntiaj teb kev sib piv kom pom qhov nruab nrab ntawm lub teeb liab. Yog lawm, VU meter qhia qhov nruab nrab ntim lossis nrov nrov ntawm lub teeb liab uas tau xa los ntawm nws.
VU meter qhia qhov nruab nrab nrov nrov ntawm lub teeb liab. Nws qhia txog lub zog thiab siv zog ntawm cov nkauj. Hauv kev sib xyaw, VU meter qhia qhov tseeb ntawm qhov sib xyaw. One ntawm lub hom phiaj ntawm VU meter yog qhov no: nws muaj kev noj qab haus huv kom muaj qee yam "ciam teb" thaum sib xyaw nkauj. 0VU tuaj yeem xav tias yog ciam teb. Tab sis nws tsis yog qhov txwv tsis pub tshaj. Nws yog qhov zoo mus me ntsis dhau 0VU, vim nws tsis "mob" sib xyaw hauv txhua txoj kev. Mus ntau dhau, thiab koj qhov sib xyaw tuaj yeem raug kev txom nyem. Feem ntau, 2-3VU tuaj yeem suav tias yog qhov txwv.
Kauj ruam 1: Taw qhia
LED vu meters siv IC thiab lub zog siv.
Qee lub sij hawm qhov ntsuas vu yooj yim yog qhov xav tau uas koj tuaj yeem txuas rau cov xov tooj cua.
Nov yog kev sim tsim. tus ncej muaj Circuit thiab video rau koj txaus siab!
