1. Lay the platform flat on the ground, adjust the feel of the four corners for stability, and fine-tune the movable feet until it is stable.

2. Place the tablet on the stand, adjust its fulcrum position to as close to the center as possible.

Adjust the legs initially to ensure even distribution of weight across all points of contact.

4. Utilize a leveling instrument (such as a level or electronic level) to check the flatness of the plate, fine-tune the support points until it meets the horizontal position.

5. After the initial adjustment is qualified, let it stand for 12 hours before copying. If it's not qualified, further adjustments are needed. Use only after it passes the test.

6. Perform periodic maintenance inspections based on the actual on-site environmental cycles.
