Test Procedures

(1) Install the spring or elastic component securely in the appropriate fixture.

(2) Select the measurement mode (tension or compression) and set the test parameters, including load range, displacement, and speed.

(3) Start the test; the machine will apply load and record deformation and force data automatically.

(4) Monitor the measurement display during testing to ensure correct operation.

(5) After completion, stop the machine and remove the tested component carefully.

(6) Record test results and compare with specifications to evaluate spring performance.

(7) Repeat testing if multiple samples or different load conditions are required.

Maintenance Information

(1) Regularly inspect fixtures, load cells, and moving components for wear or damage.

(2) Lubricate guide rails and mechanical parts as recommended by the manufacturer.

(3) Clean the testing area and components after each test to remove debris.

(4) Check electrical connections and control systems periodically to ensure safety.

(5) Store the machine in a clean, dry environment when not in use.

(6) Follow operational safety procedures to prevent injury during testing.
