This paper introduces the meaning of copper ball quasi dynamic calibration and the method of high and low temperature copper ball pressure table. According to the two ideas of temperature correction of plastic manometry device - pressure correction and deformation correction, the deformation analysis Correcting the dimensionless similarity ratio of environmental temperature on the pressure of copper ball, the correction formulas of pressure and deformation were deduced by means of regression analysis technique with the help of the quasi-dynamic calibration data of pressured copper ball under different ambient temperatures. Copper ball of high and low temperature quasi-dynamic calibration experiments were validated and the comparison of the two methods
