The range of results during a shift or section test must not exceed what value of the maintenance tolerance?

The correct answer is that the range of results during a shift or section test must not exceed the absolute value of the maintenance tolerance. This is crucial for ensuring that weighing instruments remain accurate and reliable throughout their operational lifespan.

Maintenance tolerance refers to the allowable error range within which a scale or weighing instrument must operate correctly. The absolute value signifies that regardless of the direction of the deviation (whether it is slightly over or under the target weight), the instrument should not exceed this tolerance in either direction. By adhering to this standard, it helps ensure compliance with regulations and maintains the integrity of measurements taken in various settings.

Selecting a specific numeric value or percentage, such as 0.1 grain, 0.05% of test load, or 0.01 inch, could lead to confusion, as those values can vary significantly depending on the type of scale, its capacity, and the specific application. The emphasis on maintaining tolerance as an absolute value focuses on the broader standard of accuracy rather than a fixed number, making it a more comprehensive guideline for ensuring precision during weight verification processes.
