Hardness testing is often treated as routine—until results fall outside specification. When that happens, confusion, rework, and production delays follow. In most cases, the problem is not faulty equipment, but incorrect load selection, insufficient case depth, poor surface condition, or an inappropriate test method. This guide focuses on practical hardness tester troubleshooting—helping you identify root causes quickly and correct them without unnecessary recalibration or reprocessing. Why Hardness Tester Troubleshooting Matters In production and lab environments, inaccurate hardness readings can delay approvals, trigger unnecessary re-heat treatment, or lead to rejected parts. Too often, teams recalibrate machines or question heat treatment... Continue reading
