4. Configuración
Follow these steps to set up your UT01C USB Tester:
- Deshacer: Carefully remove the UT01C USB Tester from its packaging.
- Identificar puertos: The tester has a male USB-C connector (input/output depending on connection) and a female USB-C port (output/input depending on connection).
- Connect for Testing:
- To test a power source (charger, power bank): Plug the male USB-C connector of the UT01C directly into the power source's USB-C port.
- To test a device's charging (phone, laptop): Plug the male USB-C connector of the UT01C into the power source, then connect your device's charging cable to the female USB-C port of the UT01C.
- Encendido: The tester will automatically power on and display readings once a power source is connected.
5. Instrucciones de funcionamiento
5.1 Medidas básicas
Upon connection, the main screen will display real-time voltage (V), current (A), and power (W). Additional parameters like capacity (mAh/Wh) and temperature may also be visible.

5.2 Navegación por el menú y configuración
The tester features physical buttons for navigation:
- < / > Botones: Used to navigate through menu options or cycle between different display pages.
- Botón OK: Selecciona una opción o confirma una configuración.
- Botón de retroceso: Exits a menu or returns to the previous screen.
- Interruptor APAGADO/ENCENDIDO: Controls power or enters specific test modes.
Selección de idioma:
- Navigate to the settings interface using the navigation buttons.
- Locate the language selection option, typically found in the fourth column of the settings menu.
- Utilice el < or > buttons to select between English and Chinese.
- Presione el OK Botón para confirmar su selección.
Note: Menu options are indicated by color; deep color signifies unselected, while light color indicates the currently active option.
5.3 Advanced Testing Functions
- Fast Charging Protocol Detection: The tester automatically identifies and displays the active fast charging protocol (e.g., PD, QC, PPS).
- Medición de ondulación: Access this function through the menu to analyze the stability of the power output.
- Curve Plotting: View real-time graphs of voltage, current, and power to observe dynamic changes during charging.
