5. Setup and Installation
5.1 Physical Installation
- Prepare Panel: Open a rectangular hole on the panel of your device according to the specified hole size (76.5*39.5mm).
- Insert Monitor: Place the coulomb counter into the prepared rectangular hole.
- Secure Device: Press firmly to engage the buckle mechanism, ensuring the device is securely fastened.
5.2 Wiring Instructions
Important: The coulomb counter must be connected to the negative circuit of the battery. Connecting to the positive circuit is strictly prohibited.
- Sensor Connection: All wires from the positive (or negative) terminal of the battery must pass through the sensor for current measurement.
- Verify Current Direction: After wiring, check the display. The coulomb counter should show a positive current value when the battery is charging and a negative current value when discharging. If the current direction is reversed, it indicates that the sensor is connected upside down. Correct this by reversing the sensor's orientation.

6. Operating Instructions
6.1 Automatic Mode (Recommended)
The automatic mode simplifies initial setup and capacity calibration. It is recommended for ease of use.
- Current Zeroing (if needed): If the coulomb counter displays a non-zero current when there is no load, it needs to be cleared. Ensure no load is connected, then perform the current zeroing procedure (refer to troubleshooting if specific button is not mentioned here).
- Initial Capacity Reset: After the first use or battery replacement, the displayed capacity may not be accurate. To calibrate:
- Empty Battery: Fully discharge the battery until it is empty.
- Reset Capacity: Press and hold the designated button (usually the 'SET' or 'OK' button, or as per device specific instructions) for 3 seconds. The capacity value and percentage on the display will clear.
- Full Charge: Begin charging the battery. The capacity will automatically display 100% once fully charged. This process is fully automatic and requires no further manual settings.
6.2 Manual Capacity Adjustment (Special Case)
If, after a full charge, the capacity does not automatically display 100%, you can manually adjust it:
- Manual Fill to 100%: While the charger is still connected and the battery is fully charged, press and hold the "up" button on the device. This will manually set the displayed capacity to 100%.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the display and casing. Do not use abrasive cleaners or solvents.
- Environmental Protection: Protect the device from prolonged exposure to direct sunlight, extreme heat, or extreme cold. Ensure it operates within the specified temperature range of -10°C to +65°C.
- Connection Checks: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Current display is incorrect (e.g., positive during discharge, negative during charge). | Sensor is connected upside down. | Reverse the orientation of the current sensor. |
| Current display is not zero under no-load conditions. | Initial calibration required or drift. | Ensure no load is connected, then perform a current zeroing operation (refer to device-specific button functions if available, otherwise, a power cycle might help). |
| Battery capacity does not display 100% after a full charge. | Automatic calibration not completed or minor discrepancy. | While the charger is still connected and the battery is fully charged, press and hold the "up" button to manually set capacity to 100%. |
| Display is blank or not functioning. | No power, incorrect wiring, or device malfunction. | Check power connections and wiring. Ensure working voltage is within 9-100V. If issues persist, contact support. |
