If you encounter issues with your Battman Pro, consider the following common troubleshooting steps:
- Sense pantalla/alimentació:
- Check all power connections to the monitor.
- Verify the fuse in the power supply line (if applicable).
- Ensure the battery bank has sufficient voltage.
- Inaccurate Readings (Current/Ah/Capacity):
- Ensure the current shunt is correctly installed in the negative line of the service battery, and all loads/charges pass through it.
- Check for loose or corroded connections at the shunt and the monitor.
- Perform a "manual synchronize" after fully charging the battery to recalibrate the state of charge.
- Verify that the battery capacity setting in the monitor's menu matches your actual battery bank capacity.
- "Battery Empty" Warning Appears Prematurely:
- Check the battery capacity setting in the monitor's menu.
- Ensure the battery bank is indeed fully charged when performing a manual synchronize.
- Consider having your battery bank tested by a professional to confirm its actual health and capacity.
- Display Freezes or Behaves Erratically:
- Try power cycling the unit by temporarily disconnecting its power supply.
- Check for any signs of physical damage or water ingress (though the unit is IP65, extreme conditions can still cause issues).
If these steps do not resolve the issue, contact Mastervolt customer support or a certified technician for further assistance.
