PURPOSE:To achieve an analysis for a short time by simultaneously indicating an AF signal and signals pertaining to load and displacement with a specified computation. CONSTITUTION:Signals from AE sensors 1A and 1B mounted on a sample material W are converted into a pulse N for counting an AE event cumulative figure and the peak value Vp of the AE signal with an AE detection circuit 2 and introduced into a central processor 4 through an input/output unit 3 with a signal partaining to a load P added and a displacement X. In the central processor 4, the load and displacement signals are taken on a program when no AE is generated and memorized sequentially with a primary analysis. When an AE signal is generated, with the AE signal as interrupt signal, the output of the AE detection circuit 2 is taken and memorized with the primary analysis. As soon as the requirement is met for ending a test, results of the primary analysis memorized undergo a secondary analysis, the results of which are printed out. The generation of the AE event is outputted and indicated on a LED display from an input/output unit 3. |
