5.2 Changing Display Orientation
To change the display orientation, double-click the button located on the side of the device. This will rotate the display content by 180 degrees.
5.3 Interpreting Readings
The OLED display shows multiple parameters simultaneously:
- Voltage (V): Displays the current DC voltage.
- Current (A): Displays the current DC amperage.
- Power (W): Displays the real-time power consumption (Voltage x Current).
- Timing (H): Records the elapsed time of the measurement.
- Capacity (mAh): Accumulates the total charge transferred.
- Electrical Energy (Wh): Accumulates the total energy consumed.
6. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: The metal shell provides durability, but avoid dropping or subjecting the device to severe impacts.
7. Troubleshooting
7.1 No Display/No Readings
- Ensure the device is properly connected to both the power source and the load.
- Verify that the power source is active and providing voltage within the specified range (DC 4-30V).
- Check for any damage to the Type-C connectors or cables.
7.2 Inaccurate Readings
- Ensure all connections are secure and free from debris.
- Test with a different power source or load to isolate the issue.
- Readings may vary slightly depending on cable quality and device being charged.
