This option seems to have been renamed "Enable Power Output"

I am facing the similar issue when I test current for our custom board. Please let me know how to enable DUT in the PPK2 app.

Did you enable "DUT" in the PPK2 app?

I used clip leads from my battery to the PPK2, I can see 3.2 V going to the PPK2 from the battery, but I don't see any voltage coming out.

Oh now I understand. I would need to make a special connector to do this.

With Ampere mode, you must attach the PPK2 in between the power source and the device, so it can "watch" all the current that goes through it. Did you do this?

I only added the brown VIN wire and the other ground. In source mode the PPK2 is providing the power. I want to see how much is being used when the battery is supplying power.

Do you change connections between source mode and ampere mode?

Could explain how you understand the difference between the two modes?

Thank you Sigurd. I was able to get it to run, but the levels a very low and not what I expect. Using the PPK2 as a power source I see a draw of about 20mA. With this set up in ampere mode with no power I see .17uA..

Hi,

Could you take a picture of your setup?
