【Abstract】 LN-3A digital water level is used widely in earthquake precursor monitoring network of Heilongjiang Earthquake Administration. The authors analyze various failure and abnormal change sensor,data acquisition,data communication and observation data curve in the instrument installation and operation process,aiming at the failure and abnormal phenomenon,they analyze the causes and propose solutions. The result provides some reference for station personnel processing equipment failure and finding out the reasons for abnormal data in the first time and lays a good foundation for the safe and stable running of the instruments,and the continuous,accurate and reliable observation data.更多还原
