When using a bubble level, it is necessary to keep the instrument stable, avoid vibration and tilting, to ensure the accuracy of the measurement results.

Regularly check the accuracy and stability of the bubble level, and perform calibration and maintenance in a timely manner.

When used in different environments and temperatures, attention should be paid to the impact of temperature on liquids and bubbles to avoid errors.
