摘要

The device has a test suction cup accommodated at a deforming part. The suction cup is connected with a low pressure source (19) via a wire (1) made of a flexible material, where a control valve (18) e.g. single solenoid valve, is arranged in the wire. A pressure measuring device (6) is arranged in the wire between the control valve and the test suction cup. An acoustic display device (10), optical display device (11) and a stop switch (12) are attached to the pressure measuring device. A receiver supports the deforming part into which the test suction cup is integrated.
