Frequently Asked Questions
Q: What fast charging protocols does the RK-C1 Power Meter support?
A: The RK-C1 USB Type-C fast charging tester includes a dedicated PD (Power Delivery) physical layer protocol chip that automatically detects and performs decoy testing of multiple fast charging protocols, including USB PD and various proprietary fast-charge standards. This makes it ideal for verifying charger compatibility and cable performance.
Q: Can the RK-C1 read E-Marker cable data?
A: Yes. The RK-C1 Type-C power meter supports E-Marker reading from most major chip manufacturers, allowing you to verify cable specifications such as current rating and supported data speeds directly from the cable's embedded chip.
Q: How accurate is the RK-C1 voltage and current measurement?
A: The RK-C1 features a 16-bit ADC sampling chip delivering a voltage measurement accuracy of less than 0.01V and a current measurement accuracy of ±0.5% of the measurement range — making it highly precise for monitoring DC charging circuits between 3.6V and 28V, and currents up to 8A (with short-time peak at 10A).
Q: What is the gravity-rotation feature on this tester?
A: The gravity-rotation feature automatically detects the orientation of the device and rotates the on-screen display accordingly. This ensures the 1.14-inch IPS color screen is always right-side up regardless of how the tester is connected, providing a more convenient viewing experience.
