Operating Instructions
These weights are designed for use in various physics and science experiments. Their double-hook design allows for versatile applications.
- Connecting Weights: Each weight features hooks on both ends. This allows for easy connection to other weights, springs, force sensors, or pulley systems. Simply hook one weight onto another or onto your experimental apparatus.
- Measuring Force: When used with a spring scale or force sensor, these weights can be used to demonstrate and measure gravitational force, tension, and other forces.
- Pulley Systems: The double hook design facilitates integration into pulley systems for experiments on mechanical advantage and work.
- Mass Demonstrations: Use the calibrated 200g weights to demonstrate concepts of mass and weight.
Weights can be easily connected to form larger masses or for use in experimental setups.

Safety and Handling
To ensure safe and proper use of the weight set, observe the following guidelines:
- Avoid Impact: Do not drop the weights or subject them to strong impacts, as this may cause damage to the chrome plating or affect their calibration.
- Prevent Twisting Stress: Avoid applying excessive twisting stress to the hooks, which could deform them.
- Load Limitations: The maximum recommended pulling force for a single hook weight is 0.5 kg (approximately 5 N). Exceeding this limit may cause damage to the weight or the experimental setup.
- Intended Use: Use these weights only for their intended purpose in educational and laboratory settings. Do not use them for industrial hanging, fitness, or other applications not specified.
- Supervision: Always use under appropriate supervision, especially in educational environments.

Maintenance
The QWORK Double Hooked Weight Set requires minimal maintenance to ensure its longevity and accuracy.
- Cleaning: Wipe the weights with a soft, dry cloth after use to remove any dust or residue. Avoid abrasive cleaners or materials that could scratch the chrome plating.
- Inspection: Periodically inspect the weights and hooks for any signs of wear, corrosion, or damage. If any damage is observed, discontinue use and replace the affected weight.
Storage
Proper storage helps maintain the accuracy and longevity of the weight set.
- Keep Clean and Dry: Store the weights in a clean, dry environment to prevent corrosion.
- Use Case: Always store the weights in the provided case with separators to protect them from damage and keep them organized.
The chrome-plated finish ensures durability and ease of cleaning.
Troubleshooting
This product is a passive mechanical component, and troubleshooting is generally limited to physical integrity and proper usage.
- Inaccurate Readings: If experimental results appear inaccurate, ensure the weights are clean, undamaged, and used on a level surface with properly calibrated measuring equipment. Verify that the weights are not subjected to external forces other than those intended for the experiment.
- Damaged Hooks: If a hook becomes bent or damaged, the weight should be replaced to ensure safety and accuracy. Do not attempt to bend hooks back into shape, as this may weaken the material.
