Based on the analysis of the test requirements of the aircraft cabin conditioning system, a tester was designed to test the important parameters of the power, pressure increase and decrease register, valve action time of the UUT(unit un-der tested), which consisted of single chip micro computer, industrial control meters with RS485 bus, and program con-trolled register. The application results indicated that the tester was accurate, convenient, reliable and could satisfy the test requirement of the cabin conditioning system.
