4. Setup
To set up the Gimbal PTZ Flat Cable Test Tool:
- Connect the test tool to a power source using a USB cable. A red LED labeled "Power" should illuminate, indicating the tool is powered on.
- Carefully connect one end of the PTZ flat cable to the designated "Core Board" port on the test tool.
- Connect the other end of the PTZ flat cable to the corresponding ports for "Camera", "Roll M", or "Yaw M" on the test tool, depending on the section of the cable you wish to test.

5. Operation
The test tool is designed to check the continuity of the PTZ flat cable. Once the cable is properly connected to the test tool and powered on:
- Observe the series of small LEDs on the test tool.
- If the cable connections are good, the corresponding LEDs for the connected sections (Camera, Roll M, Yaw M) will illuminate green.
- If any LED remains off or shows an incorrect color, it indicates a potential issue with that specific line or connection within the cable.

6. Maintenance
To ensure the longevity and proper functioning of your test tool and PTZ cable:
- Keep the test tool and cables clean and free from dust and debris.
- Store in a dry, cool place away from direct sunlight and extreme temperatures.
- Avoid bending or creasing the PTZ flat cable excessively, as this can damage the internal conductors.
- When disconnecting cables from the test tool, always use tweezers or a similar delicate tool to gently release the connectors. Avoid pulling directly on the cable.
7. Troubleshooting
If you encounter issues while using the test tool:
- No LEDs light up: Ensure the USB power cable is securely connected to the test tool and a working power source. Check if the red "Power" LED is illuminated.
- Some LEDs are not green: This indicates a break or poor connection in the corresponding line of the PTZ cable. Re-seat the cable connectors firmly. If the issue persists, the PTZ cable may be faulty and require replacement.
- Difficulty connecting/disconnecting cables: Always use tweezers to carefully remove the cable. Violent disassembly can damage the delicate ports on the test tool or the cable itself.
8. User Tips
- When handling the PTZ cable, always be gentle. The flat design makes it susceptible to damage from sharp bends or excessive force.
- Before performing any repairs or replacements on your drone, ensure the drone's power is completely off and the battery is removed.
- Keep the test tool and cables in their original packaging or a protective case when not in use to prevent accidental damage.
