4. Setup and Installation
4.1 Attaching the Gimbal
- Ensure the drone is powered off and the battery is removed.
- Align the white dot on the gimbal with the red dot on the drone's gimbal port.
- Insert the gimbal into the port and rotate it clockwise until it locks securely into place.
- Verify that the gimbal is firmly attached and cannot be easily removed.
4.2 Powering On
- Insert the drone battery and power on the drone.
- Power on the remote controller.
- The gimbal will perform a self-check and calibrate automatically. Wait for the calibration to complete before operation.
5. Operation
The Zenmuse H20T is controlled via the DJI Pilot app on your remote controller.
5.1 Camera Modes
- Visual Camera (Zoom/Wide): Switch between zoom and wide-angle views for different perspectives. Use the zoom slider on the remote controller to adjust magnification.
- Thermal Camera: Access thermal imaging for temperature analysis. Various color palettes and isotherms are available in the app settings.
- Split View: Simultaneously display visual and thermal feeds for enhanced situational awareness.
5.2 Laser Rangefinder
Activate the laser rangefinder through the DJI Pilot app to measure distances to objects within the camera's field of view. The measured distance will be displayed on the screen.
5.3 Gimbal Control
Use the gimbal dial and buttons on the remote controller to adjust the gimbal's pitch, yaw, and roll. The gimbal can be stabilized or moved freely depending on the selected mode in the app.
6. Maintenance and Storage
- Cleaning: Use a soft, dry cloth to clean the gimbal and camera lenses. For stubborn dirt, use a lens cleaning solution specifically designed for optical equipment. Do not use harsh chemicals.
- Storage: Store the Zenmuse H20T in its original protective case or a similar secure container when not in use. Keep it in a cool, dry place away from direct sunlight and moisture.
- Firmware Updates: Regularly check for and install firmware updates for both the gimbal and the drone to ensure optimal performance and access to new features.
- Battery Care: If the gimbal has an internal battery (check product specifications), follow recommended charging and storage practices to prolong its lifespan.
7. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Gimbal not initializing | Improper installation, firmware issue, or obstruction. | Re-attach the gimbal, check for firmware updates, ensure no physical obstructions. |
| No video feed | Loose connection, app error, or signal interference. | Check gimbal connection, restart the DJI Pilot app, move to an area with less interference. |
| Thermal image appears abnormal | Incorrect palette settings, sensor obstruction, or calibration needed. | Adjust thermal palette in app, clean thermal lens, perform thermal calibration if available. |
| Laser rangefinder inaccurate | Obstruction, environmental factors (fog, rain), or target too far/close. | Ensure clear line of sight, check environmental conditions, verify target distance is within range. |
