What is the minimum load requirement on a livestock scale with minimum divisions greater than 5 lb?

The minimum load requirement on a livestock scale that has a minimum division greater than 5 lb is determined based on regulatory standards for accuracy and performance. For scales with larger minimum divisions, such as those exceeding 5 lb, the requirement typically ensures that the scale can accurately measure loads without being affected by factors such as load cell performance or environmental conditions.

In this case, a requirement of 20 scale divisions provides a balance that allows for sufficient resolution and accuracy when weighing livestock. This specification helps to ensure that the weight readings are precise enough for regulatory compliance and operational efficacy. It's important for livestock scales to have a minimum load that correlates with their division size to avoid potential inaccuracies that could arise from underloading the scale.

As such, the selection of 20 scale divisions is appropriate, as it aligns with best practices for weighing livestock, ensuring safety and regulatory compliance in the operation of such weighing devices.
