Regulations for working environment of imaging equipment: 1. Clean environment. The image measuring instrument is a highly precise instrument, so it cannot be contaminated with dust. Once the instrument slides, camera lenses, etc. are contaminated with dust and dirt, it can cause serious harm to accuracy and imaging. Therefore, it is necessary to clean the instruments on time and strive for a clean environment as much as possible. Staff must pay attention when entering and exiting, and it is stipulated to change boots or wear foot covers. And reduce staff access. 2. Reduce oil stains. Image measuring instruments are highly precise instruments, so their slides, camera lenses, grating rulers, and laminated glass in plan view must not be stained with oil, otherwise it will endanger all normal applications of the instrument. Be careful not to touch the instrument immediately with unclean hands, and it is best to carry pure cotton rubber gloves. 3. Sunshine exposure hazards. The detector can be placed in areas with strong natural light, otherwise it will harm the accuracy of the instrument and damage the instrument due to long-term exposure to excessively high temperatures. 4. Temperature control. The ambient temperature for placing the detector should be between 18 ℃ and 24 ℃, and should not exceed this range, otherwise the accuracy will be damaged. 5. Environmental humidity control. Environmental humidity also poses a threat to instrument accuracy, and excessive humidity can cause instrument rusting. Therefore, the general environmental humidity should be controlled between 45% and 75%.
