power prfiler kit II maximum current error?

The maximum current of my measuring board should be 8ma, but the maximum value measured by kit II is 24ma, and the average current of 100ua is correct,and the minimum value is also correct,I don't know how to Set Kit II?

    As I said, these peaks are noise from the level shifters and/or the USB power source, to mitigate this you can use a "clean" power supply instead. Since these peaks are so narrow, they only get picked up from one of the data points in the 100 000 sampling which is why the top isn't picked up by the lower sampling values.
