Yo use a spirit level
To check verticality using a spirit level, place the level against the surface you want to check. Ensure that the bubble inside the level is centered between the lines, indicating that the surface is perfectly vertical. Adjust as needed until the bubble is centered to ensure vertical alignment.
Place a ball bearing or marble on it, see if it rolls.
The best tool to check for horizontal trueness is a spirit level or a laser level. These tools can help you determine if a surface is level or if there are any deviations from the horizontal plane.
To calibrate a spirit level, place it on a flat and stable surface. Check if the bubble is centered, then flip the level and check it again. If the bubble doesn't center in both positions, adjust the screws or nuts on the level until it does.
