3. Software for automated AE System Verification systeme 4 Basic Procedure for an AE Channel Verification Fig 1 illustrates the basic procedure for a manually performed AE channel verification There must be a predefined list of test patterns to be verified A stimulus usually an AE calibrator must be set to create the predefined test patterns step by step Each pattern is fed into the equipment under verification which converts the test signal to results The operator reads the results records them in a report and checks whether or not they meet the acceptance criteria Then the next test pattern will be processed until the list is completed Finally the channel will be accepted if all results meet the acceptance criteria otherwise it will be rejected and needs repair or at least re adjustment The automated AE channel verification as well as the verification of other parts of the system will basically follow the same procedure Start Report Deviations List of Test Should be Decide Accept Reject patterns End List of Patterns measured Display of Pattern measured Stimulus Equipment under AE Calibrator Verification Fig 1 Basic Procedure for AE Channel Verification file SysVeri1105 page 5 37 Tel 49 8178 9674 400 Copyright 2011 Vallen Systeme GmbH email info vallen de Fax 49 8178 9674 444 Sch ftlarner Weg 26a 82057 Icking Munich Germany http www vallen de Vallen SysVeri So
