3.3 Fast Charging Protocol Triggering
The tester supports triggering various fast charging protocols for testing purposes.
- On Interface 4 (Protocol Trigger Display):
- Click the '+' key: To move the cursor and select the fast charging protocol to be triggered (e.g., PD, QC2.0, QC3.0).
- Click the '-' key: To trigger the fast charging protocol specified by the light label.
WARNING: When the fast charging protocol is triggered, the instrument may output a voltage greater than 5V. Do NOT connect other equipment externally to avoid burning the equipment by high voltage. The meter may restart several times during the triggering of the fast charging protocol.
3.4 Specific Protocol Operations
- PD Protocol Trigger Interface:
- Click '+' or '-': To switch the Fixed file of the PD protocol.
- Press and hold the '-' key: To enter the PPS voltage regulation interface.
- In PPS voltage regulation interface:
- Click '+' or '-': To adjust the step voltage specified by the cursor.
- Press and hold the '+' key: To switch the step voltage.
- If there are multiple PPS files, press and hold the '-' key: To switch the PPS file circularly.
- To quit protocol triggering: Click the 'M' key.
- QC 2.0 Protocol Interface:
- Click '+' or '-': To switch the voltage.
- To exit protocol trigger: Click the 'M' key.
- QC 3.0 Protocol Interface:
- Click the '+' key: To increase the voltage by 0.2V steps.
- Click the '-' key: To decrease the voltage by 0.2V steps.
- To exit protocol triggering: Click the 'M' key.
4. Device Settings
The tester allows for customization of certain operational parameters.
4.1 Accessing Settings
- Long press 'M' in any interface: To enter the setting menu.
- Long press 'M' in the setting interface: To exit the setting menu without saving changes.
4.2 Adjusting Sleep Time
- While in the setting menu, click '+' or '-': To move the cursor to "Sleep Time".
- Click 'M': To cycle through sleep time options. When the time is "Oo", the device will never sleep.
- Move the cursor to "Save" and click 'M' to save the settings.
4.3 Setting Display Direction
- While in the setting menu, click '+' or '-': To move the cursor to "Display Dir".
- Click 'M': To set the screen display direction (this can also be switched by long-pressing '-' in interfaces 1-4).
4.4 Viewing Software Version
- The "Version" option in the setting menu displays the current program version of the device.

6. Maintenance
To ensure the longevity and accurate performance of your OSS TEAM Fast Charging Tester, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the device. Avoid using liquid cleaners or solvents, as they may damage the display or internal components.
- Storage: Store the tester in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts, which could damage the internal circuitry or the screen.
- Environmental Conditions: Do not expose the tester to water, high humidity, or corrosive environments.
7. Troubleshooting
If you encounter issues with your Fast Charging Tester, try the following solutions:
- No Display/No Power:
- Ensure the tester is correctly connected to a working power source.
- Verify that the power source itself is functioning (e.g., try charging a device directly from it).
- Check for any visible damage to the tester's connectors.
- Inaccurate Readings:
- Ensure all connections are secure and free from debris.
- Try using different cables and power sources to rule out external factors.
- If the issue persists, the device may require professional inspection.
- Fast Charging Protocol Not Triggering:
- Ensure your power source and connected device both support the desired fast charging protocol.
- Follow the protocol triggering steps carefully as outlined in Section 3.3 and 3.4.
- Remember the warning about high voltage output during triggering; ensure no sensitive devices are connected to the output during this process.
8. User Tips
- Monitor Charging Efficiency: Use the energy (Wh) and capacity (Ah) statistics to track how much power your devices are actually receiving over time. This can help identify inefficient chargers or cables.
- Cable Testing: The tester is excellent for comparing different charging cables. A poor-quality cable can significantly reduce charging speed, even with a fast charger.
- Charger Compatibility: Use the protocol triggering feature to verify if your charger supports specific fast charging standards (PD, QC2.0, QC3.0) and at what voltage/current levels.
- Safety First: Always heed the warning about high voltage output when triggering fast charging protocols. Disconnect any sensitive devices from the tester's output before initiating a protocol trigger.
