Quality control of components in the automatic meteorological station

Since automatic meteorological station is high integrated micro-electronics equipment,it is especially sensitive to lightning electromagnetic impulse,as well as it being harmed by lightning impulse overvoltage.

This paper narrates the calibration method of the spot calibration of the automatic meteorological station and how to operate correctly in order to better content with the calibration standard during the calibration.
