On the resistance scale of a digital meter, what does the lazy 8 symbol signify?

The lazy 8 symbol on the resistance scale of a digital multimeter represents infinity. This symbol visually resembles the number eight lying on its side and indicates that the resistance is so high that it cannot be measured, effectively meaning an open circuit. When the meter displays this reading, it suggests that there is no continuity in the circuit or component being tested. This concept is crucial in understanding electrical circuits, as identifying open circuits or non-functional components helps in troubleshooting and ensuring proper system operation.
