Battery
-
Can the battery be carried on board?
The energy of a single battery is 82Wh. According to airline requirements, the battery can be carried on board.
-
Can the battery be used in a low temperature environment?
When using the battery in a low temperature environment, the battery life may be reduced, please be sure to fly timeously. For optimal performance, it is recommended to keep the battery temperature above 15 °C before flying.
-
How do I maintain the battery?
1. Do not expose the battery to temperatures below -10°C or above 40°C, which will shorten the battery life and may cause fire, explosion or other permanent damage;
2. Do not charge immediately after flight; it is recommended to charge the battery after it drops to room temperature;
3. The ideal charging environment temperature of the battery is 10 °C~30 °C;
4. The ideal storage environment temperature of the battery is 22 °C~28 °C. When storing the battery, the surroundings should be clear from water and moisture, and must avoid sunlight;
5. Recharge and discharge the battery every 3 months or so to keep the battery active.
-
How long does it take to fully charge the battery?
It takes approximately 90 minutes to fully charge each battery.
-
Can the batteries of the 640T and EVO II series be universal?
Yes.
Perception System
-
Does the aircraft support 2D and 3D modeling?
Yes, although this aircraft model is not specifically designed for surveying and mapping, it is functionally supported.
-
What factors affect the accuracy of temperature measurement?
A. Influence of the atmosphere: the higher the temperature and humidity of the atmosphere, the greater the temperature measurement error.
B. The distance between the camera and the measured object: the farther the distance, the greater the temperature measurement error.
C. The emissivity and background temperature of the object: When the surface emissivity of the measured object is low and the background temperature is high, it will cause a large temperature measurement error.
-
In what mode can the temperature alarm function be used?
Regional temperature measurement.
-
When to use FFC flat field calibration?
When noise appears on the screen, select FFC calibration to optimize image quality.
-
Does it support temperature post-processing?
Yes, we provide free temperature analysis tool IR PC TOOL.
