7. Troubleshooting
If you encounter issues with your ANCEL BM300PRO, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Bluetooth Connection | Bluetooth is off on phone; device out of range; metal obstructions; app not open. | Ensure phone Bluetooth is on. Move closer to the device (within 15m/50ft). Relocate the device away from thick metal. Open the ANCEL BM300PRO app. |
| Inaccurate Readings | Loose connections; corroded battery terminals; incorrect battery type selected in app. | Check that clamps are securely attached to clean battery terminals. Verify the correct battery type (lead-acid/lithium) and voltage (6V/12V/24V) are selected in the app settings. |
| No Alerts Received | App notifications disabled; app not running in background; device not connected. | Check your phone's app notification settings. Ensure the ANCEL BM300PRO app is allowed to run in the background. Confirm the device is connected via Bluetooth. |
| 6V Battery Cranking/Charging Test Not Working | This functionality is not supported for 6V batteries. | This is expected behavior. The device only monitors charge status, voltage, and temperature for 6V batteries. |
