9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate or inconsistent readings | Scale is on an uneven surface; Batteries are low; Scale moved between measurements; User not standing still. | Ensure scale is on a hard, flat, stable surface. Replace batteries. Avoid moving the scale. Stand still during measurement. For best accuracy, weigh yourself at the same time each day under similar conditions. |
| Scale only shows weight, no other metrics | Not standing barefoot; Feet not making proper contact with electrodes; App not connected or profile not set up correctly. | Ensure you are standing barefoot with feet centered on the electrodes. Verify the Vihealth app is open, connected via Bluetooth, and your user profile (age, height, gender) is correctly entered. Full body composition analysis requires electrical impedance measurement through bare feet. |
| Bluetooth pairing issues or frequent disconnection | Bluetooth interference; App or phone issue; Scale battery low. | Ensure Bluetooth is enabled on your phone and the app is open. Try restarting your phone and the app. Replace scale batteries. Move closer to the scale. If issues persist, try unpairing and re-pairing the scale in the app's settings. |
| Scale unit (KG/LB) keeps changing | Unit setting reset. | Check the unit switch in the battery compartment (if available) and ensure it's set to your preferred unit. If the issue persists, ensure the app's unit setting matches and is stable. |
