PROBLEM TO BE SOLVED: To automatically evaluate the durability of an electric equipment by repeatedly executing the locking and unlocking of a door lock in an electric equipment, the opening/closing of a door and the operation of the electric equipment by means of a test control part. SOLUTION: An automatic tester is constituted of a door lock driving part 11 for the door 1A of a sterilizer 1, the open/close driving part 21 of the door 1A and the test control part 31 controlling the both driving parts 11 and 21 and the electric operation of the sterilizer 1. The door lock driving part 11 and the door open/close driving part 21 are respectively constituted of air cylinders 12 and 22 by compression air. The both cylinders 12 and 22 are repeatedly driving-controlled by the test control part 31 so that the locking/ unlocking of the lock in the door 1A and door opening/closing. Moreover, the control board 3 of the sterilizer 1, a water feeding device and a water level detecter, etc., are repeatedly operated in accordance with the lock state and the open/close state of the door 1A. The repeated operation times are set and counted so that the durability of the sterilizer 1 is evaluated. |
