The weighing gauges have been widely used nationwide in ground observing stations, undertaking the observation task of winter precipitation and providing observation data for winter precipitation forecast and service. Currently, 126 sets of weighing gauges have been put to use by the Beijing Meteorological Service, of which 90% are DSC2 weighing gauges. This paper focuses on the introduction of basic principles and the data quality control algorithm of DSC2 weighing gauges, and then two kinds of typical common faults are analyzed to propose the corresponding judgment methods and solutions. Finally, several precautions of daily maintenance for DSC2 weighing gauges are put forward to reduce related equipment failures.
