Setup and Connection

To begin using your KWS-2303C USB C Tester, follow these simple steps:

1. Identify the Type-C Male Port and Type-C Female Port on the tester.
2. Connect the Type-C Male Port of the tester to the power source (e.g., charger, power bank, computer's USB-C port).
3. Connect your device (e.g., smartphone, tablet, laptop) to the Type-C Female Port of the tester using a compatible USB-C cable.
4. The tester's screen will illuminate and display real-time charging data once both input and output connections are established.

Important Note: Due to PD (Power Delivery) protocol limitations, the USB-C tester screen will only light up if both the output (device being charged) and input (power source) ports are connected. Ensure a complete circuit for proper operation.

Curve Function:

The upgraded curve function allows for real-time graphical representation of voltage and current. To access and configure this feature:

• Navigate to the curve display interface using a single click.
• Long press the button to set the recording time for the curve page (options: 5 minutes, 15 minutes, 60 minutes, 2 hours).
• The voltage and current scales on the graph will automatically adjust based on the actual measured values for optimal visualization.

Recording Maximum Values:

The tester automatically records the maximum voltage, current, and power detected during a charging session. This feature provides insight into peak performance and helps identify potential issues or limitations of your charging setup.

Specifications

Maintenance

• Keep the device clean by wiping it with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Store the device in its provided storage case when not in use to protect it from dust and physical damage.
• Avoid exposing the device to direct sunlight or high temperatures for extended periods.

Troubleshooting

Q: The screen does not light up when connected.

A: Ensure both the input (power source) and output (device being charged) ports are connected. The tester requires a complete circuit to activate its display due to PD protocol limitations. Verify that the power source is active and the connected device is drawing power.

Q: Readings appear inaccurate or fluctuate significantly.

A: Check all cable connections to ensure they are secure. Try using different USB-C cables and power sources to rule out faulty accessories. Ensure the device is not exposed to extreme electromagnetic interference.

Q: The device is unresponsive to button presses.

A: Disconnect and reconnect the tester from the power source to perform a soft reset. If the issue persists, ensure the button is not physically stuck or damaged.
