Key Points for Using a Laser Level:
Power-On Calibration: Switch on the side power switch and ensure the instrument is level using the automatic calibration system (by observing the position of the bubble).
Measurement Operation: Place the working surface firmly against the surface being measured; take a reading only after the bubble has come to a complete standstill.
Data Calculation: Actual Tilt Value = Indicated Value × Measurement Length × Number of Error Grids.
Zero-Point Calibration: A zero-point check must be performed before use; if the deviation exceeds the allowable limit, correct it by adjusting the calibration screws.
Safety Precautions: Strictly avoid directing the laser beam into human eyes; take precautions against electric shock and protect sensitive components.
