New operators usually need only a short introduction to begin using the Class H tester effectively. The machine is designed for straightforward operation, so most of the workflow is guided by the touch screen and the built-in controls. A typical onboarding session covers how to select the correct striking knife for ASTM or ISO work, how to position and center the specimen, how to set the starting angle and how to run a safe impact cycle. This takes little time because the machine handles the heavy steps automatically, including raising the pendulum and returning it after the strike.

For labs using the instrumented version or connecting the tester to analysis software, additional training may be helpful. This includes learning how to read force–time graphs, how to interpret advanced fracture parameters and how to export or store digital results. Even here the process stays simple, and operators often become confident within a few sessions. The system’s layout and instructions are designed so that new users can reach consistent, repeatable results without needing deep prior experience in impact testing.
