Which characteristic is true about the public weighing services of a weigh master?

The characteristic that a weigh master is not required to provide public weighing services acknowledges the flexibility in their operations. Weigh masters often have specific licenses and are responsible for ensuring that measurements are accurate and compliant with regulations. However, they are allowed to function with discretion regarding when and how they provide public services. This means that while they can offer weighing services, they are not mandated to do so at all times or even during prescribed business hours, allowing them to manage their own schedules and business needs efficiently.

In many cases, public weighing services can be offered based on demand or operational capacity, rather than being an obligatory duty of the weigh master. This autonomy helps weigh masters maintain a balance between serving the public and managing their businesses effectively.
