PROBLEM TO BE SOLVED: To provide a loose contact tester by which a test can be executed precisely, easily and safely by a method wherein a collision member and a push-pull actuator are installed at a moving part and a shock is applied automatically. SOLUTION: A volume 8 is operated, the output of a push-pull actuator 7 is set, and a shock to be applied is adjusted. When a movable switch 9 is operated, the actuator 7 is driven, a collision member 20 is pushed out, and the shock is applied to an object 3 to be tested. After that, when the actuator 7 is driven, the collision member 10 is pulled back. When the collision member 10 gives the shock to the object 3 to be tested, the shock is transmitted to a shock sensor 4 via the collision member 10. The shock which is sensed by the shock sensor 4 is displayed on a monitor part 5. When an operator refers to its information, the shock which is given to the object 3 to be tested can be confrimed, and the shock to be applied can be changed properly by referring to its value. |
