Abstract Based on the instructional methods of QXT 84-2007 Test Specification of Meteorological Low Speed Wind Tunnel Performance,stability test for DZS-Ⅱ Meteorological low-speed wind tunnel is conducted.By building the mathematical model,and in accordance with the verification regulations of JJG 431-2014 Portable 3-cup Anemometers,it can be judged that the stability of each velocity point in the wind tunnel is not qualified.After inspecting the device status of the wind tunnel and analyzing the factors caused the unqualified stability,the restoring method for the wind tunnel stability is proposed.At last,suggestions on the daily use and maintenance of the wind tunnel are given to ensure that the equipment in the wind tunnel can keep accurate and reliable in the process of measurement.

Key words： low-speed wind tunnel test stability restoring maintenance
