In recent days, heavy rain and thunderstorms have occurred throughout the country, and the low-lying areas, especially in the south, even have a water line that exceeds the knee. Summer is a period of frequent typhoons. Special attention must be paid to personal safety. As one of the precision instruments, the image measuring instrument also needs to pay attention to whether there are any problems after the typhoon. The following introduces what failures the measuring instrument is prone to, and maintains the image measuring instrument correctly, thereby reducing instrument failure.
1. Accuracy failure. Including the inaccurate XYZ axis accuracy, the measurement accuracy of the two coordinates is poor, the error of the angle indication is large, and the measurement error of different planes is large,
2. The workbench is faulty. Generally, it is easy to have smooth rod idling, polished rod transmission has carbon carving, friction transmission type is not smooth, working table movement has noise, working table movement has stuck phenomenon, etc.
3. The screen is faulty. There is abnormal noise when moving and rotating, the friction force is large and uneven when rotating
4. Failure of the lifting drive. The common ones are abnormal sounds during lifting, unable to ascend and descend, falling with a sense of falling, bouncing, large gap between transmission time and space, and fine adjustment without transmission
5. Electrical failure. Common failures include light bulbs not turning on, axial fans not rotating, easy to burn light bulbs, easy to burn fuses, transformer overheating, damage, etc.
6. Electronic failure. If the button of the electric box fails, etc.
7. Image imaging failure. When the objective lens is zoomed, the crosshair and the aiming point will move to a large extent.

How to maintain the image measuring instrument in the summer when typhoons are frequent?
1. Move the image measuring instrument to a high place or increase it to prevent the equipment from getting wet
2. Keep the equipment in a dry environment at normal temperature, and keep the temperature and humidity of the equipment room within an appropriate range
3. After use, power off or add a grounding module to the device in time to avoid short circuit of the device due to voltage jump during thunderstorm.
4. After the typhoon thunderstorm weather ends, you should check whether the various functions of the equipment are normal. If you find the above fault, please contact us for repair.
