Usb Tam sim no Thiab Voltage Meter

Khoom Taw Qhia: Ib-theem digital voltmeter

Usb Tam sim no Thiab Voltage Meter yog qhov ntsuas tam sim no thiab qhov ntsuas hluav taws xob nrog cov khoom siv digital. Nrog rau kev txhim kho txuas ntxiv ntawm cov thev naus laus zis thiab microcomputer thev naus laus zis, cov ntsuas ntsuas digital thiab cov khoom siv tshiab thiab cov ntaub ntawv kaw lus nrog ib qho nti microcomputer raws li cov tub ntxhais tau siv ntau dua thiab dav siv hauv kev lag luam automation thiab kev lag luam tswj. Zoo li cov lus taw qhia, cov ntsuas ntsuas digital sib tw nrog ntau lub ntsuas thiab cov khoom xa tawm los ntsuas hluav taws xob, siab, qib, qib kua, ntws tus nqi, ntsuas kub, thiab lwm yam, thiab tso saib cov txiaj ntsig ntsuas ncaj qha hauv daim ntawv digital.

Cov lus qhia digital yuav tsum ua ntej hloov pauv qhov hloov pauv tsis tu ncua kom muaj nuj nqis rau hauv kev hloov pauv digital ntau (A / D hloov dua siab tshiab), thiab tom qab ntawd lub txee (yog tias lub teeb liab tawm tswv yim yog qhov ntau, ces lub txee ncaj qha), sau npe, decoders, thiab Thaum kawg tshwm sim ntawm cov kua siv lead ua kua lossis LED digital.
Qhov tseeb, feem ntau ntawm Usb Tam Sim No Thiab Voltage Meter yog nyob ntawm voltmeter raws li lub cev tseem ceeb, ntau lub cev muaj zog tau hloov mus rau hauv cov khoom siv hluav taws xob sib txuas tom qab inductive kis tau tus mob, cov tswv yim ntawm qhov ntsuas yuav ua cov teeb liab hluav taws xob rau hauv. cov pa hluav taws xob cov paib, yog li feem ntau ntawm cov khoom ntsuas digital lub ntsiab lub cev tsuas yog lub voltmeter, qhov sib txawv yog qhov kev hloov pauv hloov pauv hloov pauv.

Lub koom haum qauv:

Usb Tam sim no Thiab Voltage Meter yuav tsum muaj A / D hloov dua siab tshiab, tsis muaj nyiaj them poob haujlwm thiab ntsuas kev hloov pauv peb ntu.

a, A/D hloov dua siab tshiab: cov analog kom muaj nuj nqis yog hloov dua siab tshiab rau hauv ib tug digital kom muaj nuj nqis, muaj ib tug tshwj xeeb ib nti.

b, nonlinear them nyiaj: feem ntau ntawm cov ntsuas ntsuas thiab cov txiaj ntsig qhia pom qhov tsis sib xws, txhawm rau txhawm rau tshem tawm qhov tsis raug, yuav tsum tau muab ntxiv rau hauv qhov ntsuas qhov ntsuas tsis yog kab hluav taws xob. Cov kev siv feem ntau yog: analog nonlinear them nyiaj txoj kev, nonlinear digital-rau-analog hloov dua siab tshiab txoj kev, cov kev them nyiaj digital nonlinear thiab lwm yam.

c, scale transformation: feem ntau muaj ib tug proportional kev sib raug zoo ntawm tus nqi ntsuas thiab engineering tus nqi, lub rooj zaub digital yuav tsum tsis txhob yog tus nqi nkag, tab sis qhov tseeb engineering tus nqi, yog li qhov kev hloov pauv yuav tsum tau ua. General digital display meter display range yog tag nrho cov ntau yam tuaj yeem teeb tsa.

d, cov zaub tam sim no voltmeter tuaj yeem txuas nrog ua haujlwm.
