operation method

1. Sampling: Cut more than 4 pieces of 250mm×250mm samples

2. Observation: Put one of the samples on the rotatable workbench. Turn on the fluorescent lamp, and check the visible dust on the sample surface under the fluorescent lamp. When observing, keep the visual distance of the eyes at 250~300mm, and use different marks to circle the dust in different areas; it is also possible to record the number of dust in the same area according to the size of different areas.

3. Comparison: Rotate the workbench by 90°. After each rotation, use the standard Dirt Count picture to identify the size of the Dirt Count area on the sample. You can also use different areas to mark the newly discovered Dirt Count until you return to the original position.
