Cov txiaj ntsig dab tsi ua rau lux meters muab?
● Me me thiab lub teeb yuag (Compact Size, Lub teeb yuag)
Lub sijhawm siv lub ntsuas hluav taws xob yog qhov dav heev, thiab lub sijhawm siv feem ntau nyob hauv ntau qhov chaw. Yog li ntawd, thawj qhov yuav tsum tau ua ua ntej rau lub ntsuas hluav taws xob portable yog qhov me me thiab lub teeb yuag.
● Qhov tseeb﹝ Muaj tseeb﹞
Txawm hais tias lux meter yog qhov zoo lossis tsis muaj kev sib raug zoo nrog nws qhov tseeb. Ntawm chav kawm, nws kuj yog ze ze rau nws tus nqi, yog li nws yog ib qho tsim nyog yuav tau yuav ib lub lux meter nrog qhov tseeb ntawm tus nqi tsim nyog. Feem ntau, qhov yuam kev yuav tsum tsis pub tshaj ± 15 feem pua.
● Xim Xim ﹝ Xim Xaus ﹞
Cov hom teeb pom kev zoo yog tag nrho-encompassing. Qee qhov tsom mus rau cov teeb liab siab siab nrog lub wavelengths ntev, los yog xiav-violet nrog luv wavelengths xws li Daylight fluorescent teeb; kuj tseem muaj ntau qhov sib npaug sib npaug xws li incandescent noob series. Qhov rhiab heev ntawm tib lub teeb pom kev zoo rau qhov sib txawv wavelengths yuav txawv me ntsis. Yog li ntawd, yuav tsum tau them nyiaj kom tsim nyog.
● Cosine Compensation﹝Cosine Compensation﹞
Txhua leej txhua tus paub tias qhov ci ntsa iab ntawm qhov chaw illuminated muaj feem xyuam nrog qhov xwm txheej ntawm lub teeb ci. Ib yam li ntawd, thaum ntsuas nrog lub teeb ntsuas lub teeb, qhov xwm txheej ntawm lub ntsuas hluav taws xob (Sensor) thiab lub teeb pom kev zoo yuav cuam tshuam rau kev nyeem ntawv tus nqi ntawm lub teeb ntsuas. Yog li ntawd, seb lub ntsuas hluav taws xob zoo puas muaj lub luag haujlwm ntawm cosine them nyiaj tsis tuaj yeem tsis quav ntsej.
