摘要
LT31透射仪集成了一个前散射仪,用于对透射仪进行自动校准。利用前散射仪在高能见度下的测量数值,不断对透射仪进行校准使得透射仪测量保持良好状态。为此,本文详细的介绍了LT31透射仪进行自动校准时所需满足的条件,以及如何人工校准LT31大气透射仪和PWD前散仪。
A forward scatter sensor is an integral part of the LT31 system.It is used to fully calibrate the transmittance measurement automatically. Using the measured values by forward scatter when the visibility is high,the transmissometer is constantly calibrated so that it can be kept in good eondition.Inthisarticle,the LT31 auto-calibration situation and the steps of LT31 and PWD manualcalibration are introduced in detail.
