Type Of uses or maintenance or calibration or storage and operating precaution of Engineering square is?

1. Uses: Engineering squares are used for measuring and marking right angles in various engineering and construction applications.

2. Maintenance: Engineering squares should be kept clean and free of debris to ensure accurate measurements. They should be stored in a dry and secure location to prevent damage.

3. Calibration: Engineering squares should be checked for accuracy regularly using a calibration tool or by comparing measurements with a known accurate square.

4. Storage: Engineering squares should be stored in a protective case or box to prevent damage to the edges and ensure they remain accurate.

5. Operating Precautions: When using an engineering square, it is important to handle it carefully to avoid damaging the edges or corners. It should be used on a flat surface to ensure accurate measurements. Additionally, it is important to avoid dropping the square or subjecting it to excessive force, as this can affect its accuracy.
