4.4 Tare Function

5. Maintenance

- Storage: Store the scale in a dry, cool place. If not in use for an extended period, remove the batteries to prevent leakage.

6. Troubleshooting
- No Display/Power:
- Check battery installation and ensure batteries are not depleted.
- Verify AC adapter connection to both the display unit and the power outlet.
- Inaccurate Readings:
- Ensure the scale is on a flat, stable surface and not touching any walls or objects.
