To read an engineer's spirit level, place it on the surface you want to check for levelness. Observe the bubble inside the vial; it should be centered between the marked lines for the surface to be perfectly level. If the bubble is off-center, it indicates the surface is inclined in the direction the bubble is moving. Adjust the surface until the bubble is centered for accurate leveling.
If you mean a 'spirit level' then when the line is in the center of the bubble then the object being measured is horizontal to the ground.
Ensure the surface to be tested, and the level itself, are clean so bits of swarf etc don't prop the level's end up and give false readings. Ensure the alignment of the level is true along the direction to be tested. Read the level then rotate it 180º to obviate or show any errors in the level.
Use of a spirit level is to find out if things are level.
A spirit level tells if things are level, horizotally or vertically.

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.

it is read in tenths of a foot, engineers scale

The Spirit Level - poetry - was created in 1996.
it is a spirit level
level 3, i activated AR code for max spirit level and they all turned to level 3

Dumpy level provides a horizontal line (parallel to earth's curvature); you can read the scale by holding it normal to the ground level. Take separate readings for separate points then compare them
im not so sure about the spirit level but a botanist
