Inspectors use various tools and methods to perform their inspections, depending on the complexity and nature of the product or process they are checking. Measuring devices such as rulers, scales, calipers, or gauges can help measure physical properties, while testing equipment like meters, scanners, sensors, or software can test performance, functionality, or reliability. Visual aids such as magnifiers, microscopes, cameras, or monitors can help inspectors gain a clearer view. Sampling is a common method where inspectors select a representative sample of the product or process to inspect instead of the entire batch or lot. Auditing is when inspectors review documents and procedures related to the product or process to ensure compliance with standards and regulations. Lastly, reporting involves documenting and communicating inspection results and findings to relevant stakeholders. This helps provide feedback and improvement suggestions for the product or process.
