4. Setup

1. Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
2. Placement: Place the test bench on a stable, level, and vibration-free workbench. Ensure sufficient space around the unit for safe operation and access.
3. Force Gauge Installation:
   • Attach your compatible NK/HP series push-pull dynamometer (digital or analog) to the designated mounting plate on the sliding mechanism. Ensure it is securely fastened.
   • If using a digital force gauge, ensure it is charged or has fresh batteries and is properly calibrated according to its own manual.
4. Fixture Installation:
   • Select the appropriate fixture for your test sample (e.g., harness terminal).
   • Mount the fixture securely onto the test bench using the provided screws or clamping mechanisms. Ensure the fixture is aligned with the force gauge's pulling/pushing axis.
5. Initial Check: Manually operate the test handle to move the sliding mechanism back and forth. Ensure smooth movement and no obstructions.

5. Operating Instructions

1. Prepare the Sample: Securely attach the test sample (e.g., harness terminal) into the installed fixture. Ensure it is held firmly and correctly positioned for the test.
2. Zero the Force Gauge: If using a digital force gauge, power it on and zero the reading before starting the test. Refer to the force gauge's specific manual for detailed instructions.
3. Position the Sliding Mechanism: Use the test handle to move the sliding mechanism so that the force gauge is in the starting position, just touching or slightly engaging the sample, depending on the test type (pull or push).
4. Perform the Test:
   • Slowly and steadily rotate the test handle to apply force to the sample.
   • Observe the force reading on the force gauge.
   • Continue applying force until the desired test condition is met (e.g., maximum force, breaking point, specific displacement). Do not exceed the maximum load capacity.
5. Record Data: Note down the peak force, breaking force, or any other relevant data displayed on the force gauge.
6. Release and Remove Sample: Once the test is complete, slowly release the applied force by rotating the test handle in the opposite direction. Carefully remove the tested sample from the fixture.
7. Repeat Tests: If multiple samples are to be tested, repeat steps 1-6 for each sample.

6. Maintenance

• Cleaning: Regularly clean the test bench and fixtures with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or components.
• Lubrication: Periodically apply a small amount of light machine oil to the sliding rails and moving parts to ensure smooth operation. Do not over-lubricate.
• Inspection: Before each use, inspect the test bench for any signs of wear, damage, or loose components. Pay close attention to the fixtures and the mounting points for the force gauge.
• Storage: When not in use, store the test bench in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Calibration: The force gauge itself requires periodic calibration by a qualified service provider to maintain accuracy. Refer to the force gauge's manual for recommended calibration intervals.
