RESTORE ACCURATE READINGS WITH A RELIABLE 500-GRAM REFERENCE

The 500g Calibration Weight for Digital Scales provides a known reference mass for testing and recalibrating compatible digital scales. By giving the scale an exact calibration point, it helps restore dependable, repeatable measurements when readings begin to drift or after the scale has been transported, moved, or stored.

This reusable weight is ideal for pocket scales, kitchen scales, ingredient scales, jewelry scales, and other digital weighing devices that specifically request a 500-gram calibration mass. Some scales with capacities above 500 grams also use a 500-gram weight during calibration, so compatibility should always be confirmed in the scale’s instruction manual. For example, American Weigh Scales lists a 600-gram pocket scale that calibrates with a 500-gram weight.

Benefits of Use

• Helps restore accurate and consistent scale readings
• Provides a known reference point for recalibration
• Allows users to test a scale for possible measurement drift
• Helps improve repeatability between weighing sessions
• Useful after transporting, relocating, or storing a digital scale
• Simple, reusable design requires no batteries or maintenance
• Compact enough for convenient storage with the scale
• Suitable for home, commercial, educational, and general weighing applications
• Can be used for a quick accuracy check without entering calibration mode
• Designed for scales that specifically require a 500-gram reference mass

A calibration weight may be used in two ways: placing it on the scale during normal weighing mode checks whether the reading is close to 500 grams, while using it in the scale’s CAL mode allows compatible models to adjust their internal calibration. Manufacturer instructions confirm that the exact calibration mass required depends on the scale model.

Size Available

• 500 Grams
• 0.5 Kilograms
• Approximately 17.64 Ounces

This listing includes one standalone 500-gram calibration weight.

How to Use

1. Place the digital scale on a flat, level, and stable surface.
2. Keep the scale away from vibration, strong airflow, and uneven surfaces.
3. Make sure the weighing platform is empty, clean, and dry.
4. Turn on the scale and allow the display to settle at zero.
5. Enter calibration mode by following the instructions for your specific scale.
6. Wait until the display requests the calibration mass.
7. Carefully place the 500-gram weight in the center of the weighing platform.
8. Leave the weight undisturbed until the scale displays “PASS,” “END,” or another completion message.
9. Remove the weight and restart the scale when directed.
10. Place the weight back on the platform in normal weighing mode to verify the reading.

Calibration button combinations and procedures vary between scale models. Always follow the scale manufacturer’s instructions rather than assuming that every digital scale uses the same process. My Weigh manuals, for example, specify that an accurate 500-gram mass is required only for particular models and capacities.

Disclaimer

This listing is for the 500-gram calibration weight only. Digital scales, trays, cases, and other accessories are not included.

Check the scale’s instruction manual before ordering or beginning calibration. A scale’s maximum weighing capacity does not always indicate the calibration weight it requires. Some models require a smaller reference weight, multiple weights, or a specific calibration sequence. Truweigh recommends using calibration weights that match the requirements of the individual scale.

Handle the weight carefully and keep it clean and dry. Do not drop, grind, file, drill, or otherwise modify it, as physical damage or material loss can change its mass. Store it separately from loose items that may scratch, contaminate, or damage the surface.

Unless the product packaging specifically identifies an OIML class, tolerance, or traceable calibration certificate, this item should be treated as a general-purpose calibration weight. It does not certify a scale for laboratory, medical, legal-for-trade, or regulated commercial use. Applications requiring documented accuracy should use an appropriately classified and certified weight.
