Reading fluctuates

[adrianGM]

I agree that a negative number is normal, given the circumstances.
The problem is not this negative number.
The problem is that the reading fluctuates (goes up and down).
Currently, there is no current running through the clamp connected to the first port, and the port reports values between 0,07A and -0.03A.
The margin of fluctuation is abnormally high. That's incorrect.
Are there any settings that have an impact on this phenomenon? Or is this a defect?

I have the same isue with 50A-1v clamp on EPHome - Home assistant.
