What do the measured values indicate about the hardness?

The hardness tester measures cane hardness by pressing a pin into the cane with a constant force when the lever is moved from the right to the left side of the tester. Moving the lever releases the mechanism that drives the pin, and the dial measures how far the pin penetrates the cane. Lower readings indicate a harder cane, while higher readings indicate a softer cane because the pin penetrates further.
