Test Analysis ntawm Illuminance Meter Calibration Device
Qhov chaw ncaj ncaj qhov yuam kev ntawm qhov ntsuas axis ntawm lub tshuab ntsuas qhov ntsuas qhov ntsuas qhov ntsuas, lub dav hlau qauv qauv thiab qhov cuam tshuam ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas ntawm qhov ntsuas qhov ntsuas, ob qho tib si cov duab thiab txoj haujlwm tsis raug cuam tshuam ncaj qha rau qhov raug ntawm photometer. txheeb xyuas/calibration tau. Ntawm cov txiaj ntsig ntawm kev txheeb xyuas qhov kev paub zoo ntawm CNAS M0031 "Calibration of Indication Value of Illuminance Meter" tau teeb tsa los ntawm Tuam Tshoj National Accreditation Service for Conformity Assessment thiab tau siv thiab ua tiav los ntawm Tuam Tshoj Institute of Metrology los ntawm 2009 txog 2010, tag nrho ntawm {{ 3}} calibration tau txaus siab. , 17 calibration cov txiaj ntsig tsis txaus siab, suav txog 83.5 feem pua ntawm cov txiaj ntsig txaus siab, thiab 16.5 feem pua ntawm cov txiaj ntsig tsis txaus siab. Raws li kev txheeb xyuas, thawj qhov ua rau tsis txaus siab calibration cov txiaj ntsig yog qhov hloov tsis raug ntawm lub dav hlau filament thiab qhov tau txais qhov chaw ntawm lub taub hau kho qhov muag.
Peb lub tsev kho mob tau ua tiav qhov txiaj ntsig zoo ntawm En{{0}}}00~0.23 hauv qhov kev txheeb xyuas qhov tseeb ntawm qhov ntsuas ntsuas ntsuas (|En|<1.00, which="" means="" satisfaction).="" based="" on="" the="" design="" and="" installation="" of="" photometer="" verification="" professionals="" and="" the="" experience="" of="" verifying/calibrating="" photometers,="" this="" paper="" analyzes="" the="" effects="" of="" these="" two="" methods="" of="" shape="" and="" position="" error="" detection="" and="" adjustment="" on="" ensuring="" the="" accuracy="" of="" photometer="" verification/calibration="">
Tshawb xyuas thiab kho qhov kev ua yuam kev ncaj ntawm qhov ntsuas axis qhov chaw ntawm lub tshuab ntsuas photometer.
Lub teeb khiav ntawm lub tshuab ntsuas hluav taws xob yog ob qho tib si hollow puag ncig lub raj, txhua qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. . Qhov siab qhov sib txawv ntawm Z kev taw qhia thiab qhov sib txawv ntawm qhov sib txawv ntawm X kev taw qhia tsim los ntawm kev sib txuas ntawm lub hollow voj voog ntawm txhua ntu, txoj kab uas hla qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm X ua ke los tsim qhov kev ua yuam kev ncaj ntawm qhov kho qhov muag.
Thaum lub sij hawm kev soj ntsuam ntawm lub teeb ntsuas, lub trolley ntsia nrog lub luminous siv tus qauv teeb (xws li raws li tus qauv teeb) thiab nws cov cuab yeej hloov hloov mus rau txhua qhov pov thawj ntawm lub teeb khiav. Cov kab txuas ntawm qhov chaw nruab nrab ntawm cov qauv teeb txav thiab qhov chaw nruab nrab ntawm lub taub hau kho qhov muag ntawm lub teeb ntsuas ntsuas ntsuas qhov ntsuas axis, uas yog qhov chaw sib txuas kab, thiab qhov sib txawv ntawm cov kab nruab nrab yog qhov ntsuas qhov chaw. ncaj ncees yuam kev. Qhov kev ncaj ncees yuam kev ntawm qhov ntsuas axis qhov chaw yog raws li qhov kev ncaj ncees yuam kev ntawm lub teeb khiav, qhov deflection ntawm lub teeb khiav los ntawm qhov hnyav ntawm lub trolley yog ntxiv, seb qhov nruab nrab ntawm lub teeb teeb thiab lub photometric lub taub hau yog ruaj khov thiab txhim khu kev qha, seb qhov kev txav thiab qhov chaw ntawm lub trolley yog qhov tseeb thiab ruaj khov, thiab lwm yam, feem ntau, nws yog qhov dav thiab siv tau ntau dua li qhov kev ua yuam kev ncaj nraim ntawm lub teeb khiav ntawm qhov chaw los cuam tshuam qhov tseeb ntawm qhov tseeb ntawm lub teeb ntsuas ntsuas. Yog li ntawd, txoj kev ntsuas qhov ncaj ntawm lub teeb khiav tsis tuaj yeem siv los txheeb xyuas qhov ntsuas qhov sib txawv ntawm qhov ntsuas axis, thiab kev kuaj pom yuav tsum tau nqa tawm ntawm txoj kab ncaj nraim ntawm qhov ntsuas qhov chaw tsim los ntawm kev sib txuas ntawm cov ntsiab lus hauv nruab nrab. tus qauv teeb txav thiab photometric center point.
Ua ntej, kho qhov chaw ntawm thawj ntu ntawm lub teeb khiav mus rau theem, txhim kho thiab kho lub trolley ruaj khov ntawm ib qho kawg (hauv qhov tseeb qhov tseeb, lub taub hau photometric ntawm lub illuminometer yuav tsum tau tshuaj xyuas yog ntsia ntawm lub trolley), tso lub autocollimator rau ntawm lub trolley ruaj khov thiab kho Nws qhov chaw kho qhov muag yog nyob rau hauv qhov sib npaug nruab nrab ntawm qhov kho qhov muag (ob lub voj voos kheej kheej). Tom qab ntawd muab lwm lub trolley txav tau (tus qauv teeb yog ntsia rau ntawm lub trolley hauv qhov tseeb qhov tseeb) ntawm ib txoj hauj lwm ze rau lub autocollimator, thiab tso lub reflector ntawm lub autocollimator ntawm lub trolley. Siv cov txheej txheem autocollimator pitch txoj kev kuaj pom, tau txais daim duab ntsuas axis tsim los ntawm qhov chaw nruab nrab ntawm lub taub hau kho qhov muag thiab qhov chaw nruab nrab ntawm cov qauv teeb txav, txheeb xyuas qhov ntsuas axis daim duab, thiab tom qab ntawd kho Z kev taw qhia thiab X kev taw qhia ntawm kev ntsuas. axis Qhov spatial straightness yuam kev yog me npaum li sai tau.
