DJI Zenmuse H20T
About the DJI Zenmuse H20T
The DJI Zenmuse H20T adds a radiometric 640×512 thermal camera to the H20's zoom, wide and laser-rangefinder sensors — a quad-sensor payload for Matrice 300 RTK; the current DJI Matrice 350 RTK specification also lists H20T as supported.

Common Failure Modes
Symptoms: The thermal view is missing, uneven or inconsistent with a known reference.
Likely areas: Lens/window condition, gain and palette settings, FFC/calibration state, environment and sensor path.
Check the exact model and DJI thermal test procedure before declaring the sensor defective.
Symptoms: A visible channel is unclear where fitted, or gimbal movement is unstable.
Likely areas: Lens, focus/zoom where fitted, gimbal, mount and firmware.
Keep visible and thermal channel symptoms separate in the service record.
Symptoms: The aircraft does not detect the payload or a channel/control is unavailable.
Likely areas: Supported aircraft/controller firmware, connector contacts, power and data link.
Power off before reseating; a firmware or pairing limit is not proof of board damage.
Symptoms: Wet contacts, damaged housing, scratched window or corrosion after exposure.
Likely areas: Seals, windows, contacts and internal power path.
Follow the exact model IP rating; no Zenmuse payload should be treated as submersible.
Repair Notes
Identify the exact thermal model and its visible/thermal channels before interpreting an image or temperature reading.
Record ambient conditions, gain, palette and calibration/FFC behavior using a controlled reference; do not infer sensor failure from one scene.
Power off before detaching the payload. Inspect connector contacts, housing and optical surfaces without forcing gimbal axes.
Retest the available channels, gimbal and temperature workflow against model-specific DJI guidance.
