Which of the following DOES NOT apply to automatic bulk weighing systems?

The reasoning behind the correct choice is that automatic bulk weighing systems are specifically designed to weigh or fill objects while they are moving on a conveyor or similar system. This functionality allows for high efficiency and accuracy in measuring large volumes of materials without the need for stopping them.

In contrast, the first choice states that they can weigh items that are stationary, which is not applicable as bulk weighing systems are intended for dynamic processes. The second statement highlights built-in error detection mechanisms, an essential safety feature that ensures the accuracy and reliability of measurements. Lastly, the fourth choice mentions that these systems are typically used for large quantities, which aligns with the purpose and application of automatic bulk weighing systems in industrial settings, where large-scale measurements are common.

Therefore, the choice identifying weighing or filling objects while they are in motion accurately reflects the key operational attribute of these systems.
