I. Tool Preparation
Level: Selectable or electronic level, accuracy at least 0.02mm/1000mm
Cleaning Cloth: Wipe the workbench surface and the level's measuring surface clean.
Rust-Preventive Oil: Apply rust-preventive oil after adjustment.
II. Operating Procedures
Cleaning and Inspection: First, clean the workbench surface and the level's measuring surface to avoid dirt affecting accuracy.
Placing the Level: Place the level on the workbench, centering the bubble.
Reading Adjustment: Record the bubble position. If it deviates, adjust the platform's support legs until the bubble is centered.
III. Accuracy Calculation
Actual Tilting Value = Nominal Graduation Value × Measured Length × Deviation Number of Graduations
Example: Nominal graduation value 0.02mm/m, length 200mm, deviation 2 graduations → Actual tilt value: 0.008mm
IV. Precautions
Handle with care: Avoid scratching the measuring surface of the level.
Avoid friction: Lift the level when moving it; do not drag it.
Regular maintenance: Check every 3 months; readjust if accuracy decreases.
