Yuav ua li cas calibrate lub Illuminance Meter?
Illuminance meter calibration txheej txheem ntawm random ntsuas qhov yuam kev feem ntau suav nrog sab nraud teeb cuam tshuam, kev hloov pauv ntawm qhov kub thiab txias, qhov hloov pauv ntawm qhov hluav taws xob hauv DC tswj fais fab mov, tus qauv teeb txav ntawm kev vibration thiab cov neeg ua haujlwm nyeem ntawv.
Hauv cov kev ntsuas random no, qee qhov tsis tuaj yeem zam tau, uas yuav tsum tau ntsuas kom txo qis qhov cuam tshuam ntawm qhov yuam kev.
Illuminance meter calibration ib puag ncig yuav tsum nyob rau hauv qhov kub thiab av noo ntawm chav tsaus ntuj, txhawm rau txo qhov cuam tshuam ntawm sab nraud lub teeb, kub thiab av noo, illuminance meter yuav tsum tau nruab rau hauv qhov chaw ua haujlwm ruaj khov (yuav tsum tsis muaj qhov muaj zog sib nqus nyob ib puag ncig. tiv thaiv electromagnetic cuam tshuam);
Qhov ntsuas kub sab hauv tsev yuav tsum khaws cia ntawm (20 ± 5) degree (photocell drift hloov nrog kub hloov).
Chav tsev yuav tsum qhuav, av noo tsawg dua 85% RH. vim av noo kuj muaj feem xyuam rau lub illuminance meter;
Vim li no, lub teeb sojntsuam ntawm lub illuminance meter yuav tsum muaj kev sib khi zoo dua, thiab lub ntsuas hluav taws xob tsis siv lub sijhawm ntev, * nws yog qhov zoo kom muaj peev xwm ua kom lub ntsuas hluav taws xob ib zaug hauv ib ntus. .
Txhawm rau txo qhov cuam tshuam ntawm kev vibration los ntawm cov txheej txheem teeb tsa, kev xaiv ntawm lub teeb rail raws li cov swb, thiab hauv cov txheej txheem kev ntsuas ntawm qeeb zawv zawg kom txo tau qhov cuam tshuam ntawm kev co.
Cov neeg ua haujlwm nyeem cov teeb meem, nws yog ib qho tsim nyog los xyuas cov neeg ua haujlwm nrog kev paub txog lub teeb pom kev zoo meter calibration kev paub thiab kev txawj ua haujlwm, thiab nyob rau hauv lub illuminance meter calibration txheej txheem conscientious thiab lub luag hauj lwm.
Illuminance meter tej kev khiav hauj lwm cov kauj ruam, illuminance meter (los yog lux meter) yog ib tug tshwj xeeb ntsuas ntawm luminosity, brightness instrumentation.
Nws yog qhov ntsuas ntawm lub teeb siv (illuminance) yog qhov degree ntawm cov khoom yog illuminated, uas yog, qhov saum npoo ntawm cov khoom tau txais los ntawm lub luminous flux thiab qhov piv ntawm lub illuminated cheeb tsam.
Lub ntsuas hluav taws xob feem ntau yog tsim los ntawm selenium photocell lossis silicon photocell thiab microammeter.
