3. Operating Instructions

3.1 Display Navigation

The UM34C features a 1.44-inch color LCD display. Use the 'PREV' and 'NEXT' buttons located on the device to cycle through different measurement screens and settings. Each screen provides specific data points such as voltage, current, power, capacity, energy, temperature, and load impedance.

3.2 Measurement Modes

• Voltage/Current/Power Detection: Real-time monitoring of voltage (V), current (A), and calculated power (W).
• Capacity/Energy Detection: Accumulates charge capacity (mAh) and energy (Wh) over time, useful for evaluating power banks or battery charging.
• Load Impedance Measurement: Displays the calculated load impedance in Ohms (Ω).
• Temperature Display: Shows the ambient temperature in Celsius (℃) or Fahrenheit (℉).
• Quick Charge Recognition: Identifies various quick charge protocols (e.g., QC2.0, QC3.0, Apple 2.4A, Samsung). Note that recognition is for reference only and may not be 100% accurate due to rapid protocol updates.

5. Troubleshooting

5.1 Bluetooth Connection Issues (UM34C Only)

Some Android phones, such as Samsung NOTE8/S8, may experience incompatibility issues with the UM34C's Bluetooth module. If you encounter connection problems, consider the following:

• Android Version: Ensure your Android device is running Android 5.0 or higher.
• App Background Activity: Allow the UM34C application to run in the background without being cleared by the system.
• Auto-Start Permission: Grant the UM34C app permission to auto-start.
• Screen Lock Activity: Ensure the app is allowed to remain active even after the screen is locked and is not cleared from memory.
• Re-pairing: Try unpairing and re-pairing the device from your phone's Bluetooth settings.

5.2 Inaccurate Readings

If you suspect inaccurate readings:

• Ensure all connections are secure and free of debris.
• Verify the power source and load are within the specified operating ranges of the UM34C.
• Avoid extreme environmental conditions (temperature, humidity) that may affect performance.
