Troubleshooting
1. Inaccurate Readings
- Issue: Readings appear inconsistent or inaccurate.
- Solution: Ensure the scale is on a flat, stable surface. Avoid drafts or vibrations. Recalibration may be necessary if the issue persists.
2. Scale Not Turning On
- Issue: The scale does not power on when the ON/OFF button is pressed.
- Solution: Check the batteries. Ensure they are correctly installed with the proper polarity and are not depleted. Replace batteries if necessary.
3. Calibration Adjustment
Calibration and adjustment are performed at the factory. However, the weighing range can shift slightly during shipping or due to changes in local acceleration of gravity. If you suspect the scale needs recalibration:
- Press the ON/OFF key to turn the scale on.
- Wait for the display to show "0.00g".
- Press and hold the MODE key until the display shows "CAL", then release.
- Press the MODE key again. The display will flash the required calibration weight (e.g., "100.00g").
- Place the required calibration weight on the center of the platform. The display will show "PASS" then return to normal weighing mode. Calibration is complete.
