FIELD: test equipment. ^ SUBSTANCE: this invention relates to test device (100) for check of operating reliability of oxygen distribution circuit (1) in crew compartment, which has many components (20, 30, 40, 50) which ensure oxygen supply from oxygen distribution circuit in the compartment to the air crew of the aircraft in emergency situation. Test device (100) includes means (20', 30', 40', 50') for electric connection of test device (100) instead at least of one of the components (20, 30, 40, 50) to circuit (1) of oxygen distribution in the crew compartment, indicator (120) to show that electric connection of test device (100) to oxygen distribution circuit (1) in crew compartment has been made in preliminary set manner, and switching means (RL1, RL2, RL3, RL4) for indication of output signal of test device (100); at that, output signal of test device corresponds to operating mode of component (20, 30, 40, 50) at its being connected to oxygen distribution circuit (1) in crew compartment. ^ EFFECT: invention also refers to application of such test device (100) and to check method of operating reliability of oxygen distribution circuit (1) in crew compartment. ^ 15 cl, 4 dwg |
