uCurrent - Grounded output voltage
« on: February 19, 2015, 08:14:53 am »
uCurrent Gold provides to Voltage output "floating" relative to VGround (so -CurrentIn + mV/uA if I remember correctly).

So is there any means to normalize this versus my defined Ground for continuous measurements (with one of the new logicX that also can do analog measurements in parallel to the digital signal captures) and capture when doing "high-side" measurements?

Low-side seems feasible, but means that the logic analyzer still has a lower ground than my circuit...

High-side I could probably measure 2 channels (VGround/VOut- and VOut+) and calc the difference.

I guess that some extra circuit would be needed if I want to avoid doing that...

Any ideas/recommendations?

Thanks, Martin
