Method for testing the reliability of a testing apparatus, especially an empty bottle inspector

Abstract

To test the reliability of a testing apparatus which tests a large number of objects of the same type for one feature, generates a feature signal for each object and checks the feature signal for fulfilment of a first condition, a test object is conducted to the testing apparatus after a number of objects and the feature signal of the test object is checked for the fulfilment of a second condition. The second condition is that the feature signal of the test object corresponds to a previously entered reference value. The reference value can be entered by storing the feature signal of a test object as a reference value.
