Test Procedures
Secure the cable sample within the tester clamps, ensuring alignment with the abrasion head.
Select the required abrasion force by installing the appropriate weights.
Set the stroke length, speed, and number of cycles via the control interface.
Confirm ambient temperature is within 20 ± 5 °C.
Start the test; the machine performs automatic forward and reverse abrasion cycles.
Monitor test progress via the display; the system stops automatically after reaching preset cycles.
Remove the sample and inspect the outer sheath for wear, scratches, or damage.
Maintenance Information
Regularly inspect abrasion heads for wear and replace if necessary.
Keep the guide rails and moving parts clean and lubricated to ensure smooth motion.
Verify weight sets are accurate and free of deformation.
Check electrical connections and temperature sensors before each test session.
Periodically calibrate speed and stroke parameters for precise operation.
