That direction is level when bubble is centered
when the bubble in the center is centered its level
To adjust the refrigerator leveling legs for stability and balance, use a wrench to turn the legs clockwise to raise the refrigerator and counter-clockwise to lower it. Check the level of the refrigerator with a bubble level and adjust the legs until the bubble is centered. Make sure all legs are firmly in contact with the floor to prevent wobbling.
Calibration of a level typically involves placing the level on a flat surface to ensure accuracy. Then, checking if the bubble is centered in the vial will indicate if the level is calibrated. If adjustments are needed, calibration screws on the level can be manipulated until the bubble is centered.
The bubble pops!
Answer The older versions had a bubble level built into the base. You adjusted the legs until the bubble was centered. Now with laser surveyors, I'm not sure how this is done.
you don't get bubble gum that's for sure

If the bubble is exactly centered the level is horizontal (or vertical if it is one of those)
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.
