| Abstract: |
| In order to effectively improve the observation data accuracy and equipment operation stability of the visibility meter in the national ground meteorological observation station, it is particularly important to carry out daily maintenance, verification and calibration, data quality control and fault repair of the visibility meter. By introducing the hardware structure and basic working principle of DNQ3 forward scattering visibility meter, and analyzing some typical faults, this paper summarizes the detection and maintenance process of the visibility meter, summarizes the corresponding troubleshooting measures, and summarizes the verification calibration and suspected error data quality control method of the visibility meter. It provides reference for frontline service personnel to carry out routine maintenance, troubleshooting, and operation monitoring of visibility meter. |
