Maintenance

Cleaning

To maintain accuracy and prolong the life of your scale, clean it regularly. Use a soft, damp cloth to wipe the surface. Do not use abrasive cleaners or immerse the scale in water. The included small brush can be used to remove dust or small particles from the weighing pan and crevices.

Storage

Store the scale in a dry, stable environment away from extreme temperatures, humidity, and vibrations. Keep the protective cover closed when not in use to prevent dust accumulation and protect the weighing mechanism.

Troubleshooting

If you encounter issues with your UNIWEIGH Digital Milligram Scale, please refer to the following common problems and solutions:

• Inaccurate Readings:
  • Ensure the scale is on a stable, level surface. Use the adjustable feet and bubble level.
  • Calibrate the scale using the 50g calibration weight.
  • Check for drafts or vibrations in the environment. Use the windproof cover.
  • Ensure the weighing pan is clean and free of debris.
• Scale Not Turning On:
