PPK2 measure input voltage

[Florian Zierer]

The PPK2 is able to generate a fixed output voltage in "source meter" mode.

When using it in ampere mode it would be nice if the applied voltage could also be measured.

Is it possible to extend the PPK2 to measure the voltage of the connected battery additionally to the current? It would be cool to see the voltage also in the line graph.

BTW. It's a great tool.

Hi, thanks for reaching out. I believe it should be possible with the current hardware at least. I can file a feature request with the PPK team and see if this can be added as part of a new software release. I can't promise anything though. I agree, it would be a cool feature!

Ok cool, thanks for writing a feature request.

I also support this feature request. It would be very helpful if you're trying to measure power directly in the battery path. Otherwise you need to use an external DAQ to measure the battery voltage in parallel to get an accurate power measurement (which, given a usable 3.7V LiPo battery voltage swing, can easily be >20% off if you're assuming the nominal voltage).

I would also find this feature useful! Please add my vote to this feature request!

And I agree the PPK2 is an awesome piece of equipment! I use it a lot, and I love it!
