Abstract
Provided is a method of designing a low-pressure chamber that provides a preset air pressure corresponding to a predetermined altitude. The method may include the steps of: calculating a predetermined error range of the preset air pressure, and calculating an amount and types of materials of a getter to be inserted into the low-pressure chamber based on the error range and a total volume of the low-pressure chamber.
