Abstract：
A data quality monitoring system for fast reconstructed event is depicted in detail for ψ(2S)data taking during 2001-2002 years' running at Beijing Spectrometer(BES Ⅱ) . In parallel with fast reconstruction of raw data, the performance and stability of BES Ⅱ subdetector can be inspected from various intuitive distributions of fast reconstructed and selected events. The system,with operation simplicity,function completeness and extension flexibility,has played and will play an important role in the quality monitoring of BES data taking.
