2. Product Components

The BAOSHISHAN DL-100LB Force Gauge and APW Test Stand Extended Version bundle includes the following main components:

• DL-100LB Force Gauge: An analog device for measuring push and pull forces up to 100LB.
• APW Test Stand Extended Version: A mechanical stand designed to provide stable and precise movement for force measurement applications.
• Metal Test Accessories: Various attachments for the force gauge to accommodate different testing requirements.
• Mounting Hardware: Screws and clamps for assembly and securing the force gauge.

3. Setup and Assembly

Follow these steps to assemble and set up your force measurement system:

1. Assemble the APW Test Stand:
   • Attach the handwheel to the designated shaft on the test stand. Use the provided hex wrench to secure it firmly.
   • Install the fixing clamps onto the test stand rails. These clamps will be used to secure the force gauge or the object under test. Ensure they are tightened with the hex wrench.
   

   Figure 3.1: Installation of Handwheel and Fixing Clamps. This image illustrates the process of using a hex wrench to secure both the handwheel and the fixing clamps onto the test stand's frame.

2. Mount the DL-100LB Force Gauge:
   • The test stand features various mounting holes to accommodate different devices. Select the appropriate holes for your force gauge.
   • Secure the force gauge to the movable carriage of the test stand using the provided screws and mounting plates. Ensure it is stable and aligned.

3. Attach Test Accessories:
   • Select the appropriate metal test accessory (e.g., hook, flat head, cone) based on the material and shape of the object you intend to test.
   • Screw the chosen accessory firmly onto the end of the force gauge's measuring rod.

4. Operating Instructions

Once assembled, the system is ready for operation:

1. Position the Object: Secure the object to be tested onto the test stand using the fixing clamps. Ensure it is stable and will not move during the test.
2. Adjust Initial Position: Use the handwheel on the test stand to move the force gauge carriage until the force gauge's measuring rod is in contact with the object. The handwheel allows for very precise control of the measuring stroke.

3. Perform Measurement:
   • For push force, turn the handwheel to advance the force gauge against the object.
   • For pull force, attach the object to the force gauge (e.g., using a hook accessory) and turn the handwheel to retract the force gauge, pulling the object.
   • Observe the analog dial on the DL-100LB Force Gauge. The needle will indicate the applied force in pounds (LB).
   • Note the peak force reading if required. The gauge may have a peak hold function (refer to the gauge's specific instructions if available).
4. Release and Reset: After measurement, retract the force gauge using the handwheel. The gauge's needle should return to zero. If it does not, gently tap the gauge or use any reset mechanism it may have.

5. Maintenance

Proper maintenance ensures the longevity and accuracy of your force measurement system:

• Cleaning: Wipe down the force gauge and test stand with a soft, dry cloth after each use. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the internal mechanisms.
• Lubrication: Periodically apply a small amount of light machine oil to the threaded rod and sliding parts of the test stand to ensure smooth operation. Avoid over-lubrication.
• Storage: Store the device in a clean, dry environment, away from direct sunlight, extreme temperatures, and corrosive substances. Keep it in its original carrying case if available to protect it from dust and impact.
• Calibration: For critical applications, periodic calibration of the force gauge by a certified laboratory is recommended to maintain accuracy. Refer to the calibration certificate for details on recommended intervals.

6. Troubleshooting

If you encounter issues during operation, refer to the following common problems and solutions:

• Issue: Force gauge needle does not return to zero.
  Solution: Gently tap the side of the gauge. If the issue persists, check for any obstructions or damage to the measuring rod. Avoid applying excessive force beyond the gauge's capacity.
• Issue: Test stand movement is stiff or jerky.
  Solution: Clean the threaded rod and guide rails. Apply a small amount of light machine oil to lubricate these components. Check for any debris or foreign objects obstructing the movement.
• Issue: Inconsistent force readings.
  Solution: Ensure the force gauge and the object under test are securely mounted and stable. Verify that the force is applied smoothly and consistently. Check if the test accessory is properly attached. Consider professional calibration if accuracy issues persist.
• Issue: Handwheel is loose.
  Solution: Re-tighten the set screw on the handwheel using the appropriate hex wrench.
