We are building an all-sky electrostatic analyzer suitable for plasma observation on the lunar surface. Considering the harsh space environment, we need to conduct various functional verification and space environment tests before launch. In this study we describe the facilities and verification methods we used. The first system is the Space Plasma Operation Chamber, which is mainly used to simulate the vacuum and plasma environment on the lunar surface. It can be used to verify the basic functional performance of the instrument under the environment setting. The second is the space ion beam system, through which an energetic ion beam is generated. We can conduct experiments to obtain signal sensitivity data at the receiving end of the instrument by adjusting the particle energy and incident direction. This is an important data calibration basis before the instrument is launched into space. The third is the thermal vacuum cycling system. The hot and cold temperature generated by this system is used to simulate the temperature difference in the space environment to test whether the instrument can work normally on the lunar surface. We also use this system to verify the functional operation and data reliability at the set temperature.
