The Ball Rebound Tester from Nextgen Material Testing is designed to measure the rebound height of a ball after being dropped onto a test material. However, the accuracy of the tester can be affected by various factors, including the properties of the material being tested, the height from which the ball is dropped, and the calibration of the equipment.

The Ball Rebound Tester typically has a measuring range between 0 and 100 percent rebound height. The accuracy of the tester is expressed as a percentage of the full-scale range. For instance, a tester with an accuracy of ±1 percent of the full-scale range can measure the rebound height within a range of ±1 unit for every 100 units of the full-scale range.

Equipment calibration is crucial to ensure the accuracy of the Ball Rebound Tester. Calibration involves adjusting the tester to ensure it provides accurate and consistent results. The calibration procedure typically involves dropping the ball onto a standard reference material with a known rebound height and adjusting the tester to match the known value.
