PM2000F Flickering analyzer is a professional testing equipment specially used for measuring light source photometric parameters and flicker evaluation parameters, and evaluating flicker safety level. The system consists of PM2000F Flickering analyzer, CHP500 high precision AC power supply (PST), Flicker software, etc. It is to test LED light source flicker index, flicker percentage, flicker frequency, PST, SVM (in accordance with the latest standards such as CIE TN: 006, NEMA 77, American Energy Star and ERP 2019), PAM modulation percentage (in accordance with CEC regulation JA 10), MP (in accordance with ASSIST recommendation and the latest standards such as American Energy Star).

IECTR 61547-1-2020 proposes a short-term flicker index PST for the evaluation of the initial flicker of light sources to evaluate the influence of voltage fluctuation at the power supply terminal on the light output fluctuation of the lighting source .
