<p>The article provides a&#xa0;brief overview of group-wise inspection methods that enable several products to be simultaneously inspected in terms of one or more parameters by means of one tool. In order to reduce the batch inspection time compared to its piece-by-piece inspection, a&#xa0;search method for group-wise inspection was developed and studied. This method relies on an approach used to find hidden faults in radio equipment by dividing the circuit into parts and then inspecting them. The requirements to be met by inspected products are defined. The effect of defect rate, batch size, and distribution of defective items throughout the batch on its inspection time is analyzed. It was proved that with uniform distribution of defective products throughout the batch, the batch inspection time is the longest and that the time of batch inspection via this method decreases significantly with decreasing defect rate. Taking the size and defect rate of the batch into account, the author determines when applying this method provides an advantage over the methods of piece-by-piece inspection. A&#xa0;device used to implement the method is described. The performance of the search method for group-wise batch inspection is evaluated for application under specific conditions. The obtained results can be used by technologists at various production facilities in the development of batch inspection processes.</p>
