Which of the following is a basic requirement for a commercial scale?

A basic requirement for a commercial scale is that it must be continuously maintained in proper operating condition by the user. This ensures that the scale provides accurate and reliable measurements, which is essential for commercial transactions where weight is a critical factor. Regular maintenance can involve checking for mechanical issues, ensuring that the scale is leveled, and cleaning components to prevent inaccuracies due to wear or debris.

While having government approval, regular calibration, and automatic operation may be beneficial or required in certain contexts, the fundamental responsibility lies with the user to ensure that the scale remains functional and precise over time. This maintenance duty is a vital aspect of ensuring compliance with trade regulations and protecting both the business and its customers.
