5. Operating Instructions
5.1 Key Operations
The single control button on the device allows for various functions:
- Short Press: Switches between different display screens (e.g., Voltage/Current, Capacity, Power).
- Quick Double-Click: Resets the cumulative capacity (mAh) to zero.
- Quick Triple-Click: Resets the cumulative power (Wh) to zero.
- Quick Four-Click: Resets the timer (00:00:00) and clears the current data group.
- Quick Five-Click: Changes the cumulative data storage group number (NO.X, up to 10 groups).
- Long Press: Enters or exits system settings, or turns the screen off/on.
5.2 Display Interfaces
The UC96 tester provides several display interfaces to show different measurement parameters.
Image 5.1: Examples of the GuliTech UC96 display interfaces, including the Chinese display, English display, capacity group number interface, and the main measurement interface, showing various parameters like Voltage, Current, Power, Capacity, and Time.
- Main Measurement Interface: Displays real-time Voltage (V), Current (A), Power (W), Resistance (Ω), Temperature (°C/°F), Capacity (mAh), Energy (Wh), and Time (H:M:S).
- Capacity Group Interface: Shows accumulated capacity and energy for the selected data group.
- USB Four-Wire Detection Interface: Provides detailed information on USB D+/D- voltage, fast charge protocol recognition (e.g., FCP, FAST), and supply voltage.

5.3 System Settings
To access system settings, long press the control button. Use short presses to navigate and quick double/triple clicks to adjust values.
- Overvoltage Alarm (OVP): Set the maximum voltage threshold. If exceeded, an alarm will sound.
- Low Voltage Alarm (LVP): Set the minimum voltage threshold. If voltage drops below this, an alarm will sound.
- Overcurrent Alarm (OCP): Set the maximum current threshold. If exceeded, an alarm will sound.
- Screen Rotation: Adjust display orientation.
- Default Settings: Reset all settings to factory defaults.
- Clear Data: Erase all stored measurement data.
- USB IAP / USB Upgrade: For firmware updates.
- Exit: Exit the system settings menu.
To adjust alarm values (e.g., overvoltage >35.0V, low voltage <3.00V, overcurrent >8.00A), short press to select the setting, then quickly double-click to increase (+) or quickly triple-click to decrease (-) the value.
5.4 Bidirectional Current Test
The UC96 supports bidirectional current testing, allowing you to measure current flow in both directions, which is useful for devices that can both charge and discharge.
