5. Troubleshooting

If you encounter issues with your scale, please refer to the following common problems and solutions:

• Press and hold the MODE button until "CAL" appears on the display.
• Press MODE again. The display will show the required calibration weight (e.g., "1000.00g").
• Place the exact calibration weight (e.g., 1kg) on the center of the platform.
• Wait for the display to show "PASS" and return to normal weighing mode. Calibration is complete.
