4.2. Batré Persentage Testing Modes
You can choose one of two appropriate ways to test your battery percentage:
- Modeu C+D- (Persén Kapasitastag(Modeu Tés e): Charging (C+) capacity adds, and discharging (D-) capacity reduces. This mode requires setting the measured battery capacity value in the product. The capacity measurement displays the current actual capacity of the measured battery after adding during charging and subtracting during discharging.
- Modeu C+D+ (Modeu Itungan Kapasitas Kumulatif): Charging (C+) capacity adds, and discharging (D-) capacity also adds (does not reduce). Both values are cumulative. This mode does not require setting the battery capacity value; simply clear the capacity to zero before each test.

Answer: Yes, Bluetooth and location information (GPS) must be turned on to allow the app to function correctly.
7. Tips pamaké
- Always ensure the CW20 meter receives independent DC5V power supply if the measured voltage is below 10V, especially when using the WiFi module.
- When setting battery percentage and alarm thresholds (OVP, LVP), carefully consider your battery type and application to prevent over-charging or over-discharging.
- For accurate capacity testing, remember to reset the capacity to zero by long-pressing the "+" and "-" keys simultaneously before starting a new test, especially in C+D+ mode.
- If you experience WiFi connection issues, try resetting the WiFi via the device's backend settings.
- Keep your device's firmware updated for the best performance and latest features. Refer to the official ATORCH website for the latest software and firmware.
