5.3 Ripple Measurement

The ripple measurement function allows you to analyze the stability of the power output. It displays a real-time graph of voltage ripple, along with sampling speed, plotting curve area, and average ripple values.

• Status Indication: Real-time or paused measurement. Press the confirmation key to switch status.
• Sampling Speed Display: Shows the +/- switch speed.
• Plotting Curve Area: Visual representation of the ripple.
• Real-time Voltage and Current Display: Can be paused at a certain moment.
• 100ms Average Ripple: Real-time display following VBUS voltage changes.

5.4 Curve Measurement

This feature provides a graphical representation of cell voltage, current, and power over time, adapting to the total voltage. It helps in understanding the charging dynamics.

• Cell Voltage Display: Curves in 4 areas, adaptively following total voltage.
• Sampling Time Display: Indicates total time of the displayed table section (+/- switching speed).
• Current Direction Indication: Follows current size to update flow rate.
• Real-time Curve Plotting: Dynamic visualization of data.
• Real-time Voltage, Current, and Power Display: Numerical values alongside the curves.

5.5 Protocol Testing (Automated)

This mode performs an automated test of fast charging protocols. It indicates the PD status, PDO maximum gear and power, PPS support, voltage supported by fixed gear, QC2.0/QC3.0 support, and protocol version.

• Status Indication: Wait for prompt after completion.
• PD Status Indication: Includes PD2.0-3.1 Fixed AVS EPR.
• PDO Maximum Gear and Power Display.
• PPS Support: Indicates whether PPS is supported and maximum adjustable PPS gear power.
• Fixed Gear Voltage: Displays supported voltage and adjustable PDO voltage groups.
• QC2.0 Fixed Slot Support Status.
• QC3.0 Adjustable Gear: Maximum trigger voltage, step 200mV.
• PD Protocol Version: Special protocols (e.g., Xiaomi private) will show specific information.

5.6 Protocol Testing (Single Decoy)

This interface allows for testing specific PD single decoy protocols. Note that the selected gear will not be triggered immediately; you must press the confirmation key again to confirm the enticement before the display synchronizes and the operation begins. Display colors (red + green) synchronize with the logic.

• Protocol Version and Stalls: Displays detailed protocol version and number of stalls (defaults to PDO, AVS EPR expansion part displayed if supported).
• Current Stall Display.
• Real-time Current.
• Current Direction.
• Supported Gear Enumeration: If more than the maximum number of display, intervals are merged to prevent data loss.
• Selected Gear Information.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: While the device features a durable metal case, avoid dropping it or subjecting it to strong impacts to prevent damage to internal components or the screen.
• Connectivity: Ensure Type-C connectors are clean and free of debris before plugging them in to prevent poor contact or damage.

7. Troubleshooting

• No Display/Power: Ensure the device is correctly plugged into a working power source. Check the cable connections.
• Inaccurate Readings: Verify that the cables used are in good condition and properly connected. Some cables may not support high power delivery, affecting readings.
• Protocol Detection Issues: If a protocol is not detected, ensure both the power source and the connected device support that specific protocol. Try different cables or power sources.
• Device Not Responding: If the device becomes unresponsive, disconnect it from all power sources and devices, wait a few seconds, and then reconnect.

8. User Tips

• Cable Quality Matters: For accurate high-power measurements and fast charging protocol detection, always use high-quality, certified USB-C cables that support the desired power levels (e.g., 240W for PD3.1).
• Monitor Charging Health: Regularly check the ripple measurement to ensure your power adapters are providing stable power, which can help prolong battery life of your devices.
• Experiment with Protocols: Use the protocol testing features to understand which fast charging standards your chargers and devices actually support, optimizing your charging setup.
• Portability: The compact size of the KWS-X1 makes it ideal for travel. Keep it in your bag or pocket to quickly check charging performance on the go.
