A set of abnormal shallow soil temperature data from the CAWS600B automatic weather station at Pingyin is analyzed and the troubleshooting procedure is described.A rapid determination of the fault location and troubleshooting approach, in case of abnormal data is given by the CAWS600B automatic weather station without a soil temperature sensor in maintenance onsite, is introduced. According to the principle of the adverse stepbystep malfunction elimination in soil temperature data acquisition, troubleshooting was conducted from five aspects: software setting, the soil temperature channel of the data collector, the signal cable, the temperature transmitter, and the temperature sensor. The results provided good references for the maintenance of the automatic station during the 11th Chinese National Game.
