ZENMUSE XT 2 User Manual
Infrared mode
Only displays the footage that infrared thermal camera captures.
MSX mode

Spot Meter and Area
Measurement Button
Fusion Degree Settings
Spot meter and Area measurement are available when using Infrared or MSX modes.
Spot Meter
The temperature of any position in an image can be measured with an accuracy of ±10°C.
Under ideal environmental conditions are ideal, the camera provides an accuracy of ±5°C.
Area Measurement
Enabling this function will display the average temperature, lowest temperature,
highest temperature, and the corresponding locations of each area in DJI Pilot.
The temperature measurement accuracy is affected by various factors:
1) Reflectivity of objects - shiny metals with high reflectivity will reflect more of the background
radiation and result in lower accuracy, whereas objects with matte surfaces will produce a
higher accuracy.
2) Temperature of background radiation - a sunny day without clouds will have less of an effect
on the accuracy than a cloudy day.
3) Air temperature and humidity - as temperature and humidity increases, accuracy decreases.
4) Distance between camera and object - as distance decreases, accuracy increases.
5) Emissivity of objects – emissivity and accuracy increase together.
When MSX is selected, adjust the accuracy of the MSX footage using MSX adjustment.
