Yuav ua li cas ceev faj yuav tsum tau noj nrog Lux meters?
① Selenium (se) lossis silicon (si) photovoltic hlwb nrog zoo linearity yuav tsum tau siv rau photovoltaic; Lub sijhawm ntev ua haujlwm tseem tuaj yeem tswj tau zoo ruaj khov thiab siab rhiab; Thaum siv cov e, xaiv cov photovoltic cell nrog lub siab nyob rau sab hauv, uas muaj qhov muaj kev rhiab siab thiab zoo li tsis yooj yim los ntawm lub teeb muaj zog
Remple Lim nrog V (λ) Kev Kho Hniav Kev Kho Lus, haum rau kev ua kom haum nrog cov xim sib txawv, nrog qhov yuam kev me me
Qhov laj thawj rau kev ntxiv cov tshuaj ntsuab ntawm lub ntsej muag (lub ntsej muag dawb lossis dawb lub kaum sab xis
Prolluminance Meter yuav tsum ua haujlwm nyob rau hauv lossis ze chav sov (drift ntawm lub photovoltaic hloov nrog ntsuas kub)
Calibration ntawm Illuminance Meter:
Ua kom ci ntawm photovoltic cell yog ls {{= Kuv / r2, thiab hloov R kom tau txais cov ntawv sau cov ntaub ntawv txawv. Hloov ua cov nplai tam sim no mus rau lub qhov hluav taws xob cenpumance raws li kev sib sau ntawm e thiab kuv.
Txoj kev calibration:
Siv lub teeb siv lub teeb ua haujlwm teeb, ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm Ammeter ntawm kev ua haujlwm ntawm lub xov tooj ntawm lub ntsej muag, thiab cov teeb meem Los ntawm qhov no, ib qho ntawm thaj chaw thaj chaw thaj tsam txawv uas kuv tuaj yeem tau txais, thiab qhov sib txawv ntawm cov photocrurrent Kuv thiab qhov kev txiav txim siab ntawm qhov kev txiav txim siab ntawm lub chaw ntsuas dej. Txoj kev ntsuas hluav taws xob nkhaus ntawm kev ntsuas Illuminance tuaj yeem faib los ntawm lub xov tooj ntawm daim ntawv Illuminance, uas yog qhov ntsuas hluav taws xob ntawm kev ua kom zoo nkauj illuminance
Yam cuam tshuam rau kev nkhaus calibration:
Thaum hloov photovoltic hlwb thiab ammeters, kev rov ua dua tshiab yog qhov yuav tsum tau; Tom qab siv Illuminance meter rau ib lub sijhawm, nws yuav tsum tau recalibrated (feem ntau 1-2 zaug hauv ib xyoos); Siab precision illuminance yuav ntsuas siv cov teeb meem teeb lub teeb ci ntsa iab; Nthuav cov kev ntsuas ntsuas hluav taws xob ntau ntawm qhov kev ntsuas Illuminance tuaj yeem hloov qhov deb R, thiab teeb tus qauv sib txawv kuj tseem siv tau los xaiv ib qho ammeter me.
