Hello. I wonder why IMU 3 is not heated.
I use Pixhawk orange cube and arducopter latest version
Two of the IMUs are on the internal isolated IMU board that’s heated. The 3rd is on the main base FMU PCB that is not isolated or heated.
This is why you are seeing the difference.
Triple redundant system with 2 IMU isolated and heated on a separate internal board above the main PCB of the FC.
but the barometer is only one heated
Same as IMU one on the isolated and heated IMU board the other is not.
