The pressure setting is mainly through the touch screen to set the pressure required by the user. The pressure of the expansion tube during operation is transmitted to the digital-to-analog conversion module through the transmitter. The pressure value is displayed on the touch screen "current pressure value". The current pressure value and the setting When the pressure values are equal, the decompression system works to relieve pressure, and the entire expansion process ends.
