Power Profile Kit PPK2 current not correct.

[WFKwok]

Hello,

i have one PPK2. Recently i find the current reading from PPK2 is relatively large compared with actual current value.

For example, actual current value vs PPK2 value:
4uA vs 35uA
3mA vs 6mA
300mA vs 500uA

So is the PPK already broken or defective?s

Is there any way i can work around like PPK2 calibration to fix the PPK2?

Or something like the current sensing resistors are broken and i can check and replace to get a good PPK2 back?

Thanks

Hello,

What do you base your "actual current values" on? And which ones are the lower of the numbers that you present? The PPK or the "actual current value"?
