Testing Tutorial

KM003C Fast Charging Protocol Test Tutorial and Instructions-3cgo

1. Long-press the right button (lightning icon on the rear) to enable the pulldown resistor and power up the device.

2. Enter the protocol test screen and verify the settings: the simulated cable icon (top right) should show 50V 5A EPR, and the bottom left should be on AUTO. This ensures accurate readings. Click "Ready" to continue.

5. You can also perform the test by connecting a cable to the tester's Type-C female socket. If a device doesn't fit the male connector, simply use a CC cable to complete the detection.

Additional Information

1. The simulated cable feature offers No E-marker (60W), 20V5A (100W), and 50V5A (240W, EPR) options. It sets the peak power ceiling for PD requests when using the male connector and supports lower tiers automatically. Setting it to 50V5A EPR by default is advised.

2. If only specific PD protocols need to be read, you can select the requested PD type as Auto, PD3.0 (SPR), PD3.1 (EPR), or prop.PPS based on your requirements.

3. To detect VOOC or MTK protocols, make sure to turn on the VOOC/MTK mode in the bottom right. For private protocol detection, the original manufacturer's cable for that protocol is required.

Precautions

When using the tester's Type-C female port, compliant cables that support the device's maximum power rating must be employed; for private protocol detection, original manufacturer cables are required to ensure proper conduction and accurate results.

When performing tests with a dual Type-C cable, the tester's female interface is orientation-sensitive; if the device fails to power on after a long-press, simply flip the cable connector.
