When sorting alloys with a comparator, what is the primary reason for keeping indications within the readout device's bounds?

The primary reason for keeping indications within the readout device's bounds when sorting alloys with a comparator is to effectively detect the possible existence of a third alloy. In the context of alloy sorting, maintainable and reliable readouts are crucial to discerning differences among materials. If the indications exceed the device's bounds, it could suggest the presence of an unwanted or unexpected alloy that may not be accounted for in the original sorting criteria.

This approach ensures that the values displayed on the readout remain within a defined range, which is essential for maintaining accuracy. When indications are properly contained within the device's operational range, it can provide a clear distinction between known alloys, successfully eliminating ambiguity and aiding in identifying whether a third alloy or unintended variation is present.
