I'm using the nordic ppk II to measure the power consumption of my device.
In order to validate the charge (current integral) displayed by the PPK2 i put two PPK2 daisy-chained into my current path. Both are configured as ampere meter and started at the same time.
Even after a short while the two devices report different Charge. e.g. after 13 minutes one reports 24 Coulomb and the other 26 Coulomb. Why is that? Can I somehow avoid this drift?
