Confirm testing medium or stylus is correctly installed.
Running the Test
Start the program; the tester executes pre-set motion patterns.
Monitor test curves and data in real-time.
Upon completion, the system automatically stops and returns to initial position.
Post-Test Evaluation
Inspect the sample surface for scratches, wear, or impact damage.
Export test data and generate reports as needed.
Maintenance Information
Regularly clean and inspect test heads and working stage.
Ensure mechanical guides and X-Y stage operate smoothly.
Calibrate load and motion parameters periodically for accuracy.
Replace worn or damaged test heads immediately.
Keep software updated for optimal functionality.
