- If the bubble is not centered, the surface is not plumb. Adjust the surface until the bubble is centered.
4.3. Measuring 45-Degree Angle
- Place the level against the surface you wish to check for a 45-degree angle.
- Observe the 45-degree vial. The bubble should be centered precisely between the two indicator lines.
- If the bubble is not centered, the surface is not at a 45-degree angle. Adjust the surface until the bubble is centered.
