Test Procedures

Sample Installation

Place the metal specimen securely in the sample holder. Ensure it is level and fixed.

Parameter Setup

Select test mode (dry or wet), load, and test length on the control system.

Execution

Initiate the scratch test. The stylus moves along the defined path while applying the chosen load. Frictional force is measured in real time.

Data Recording and Analysis

The system converts frictional data into a graphical curve. Optional software can be used for further analysis and documentation.
