PPK2 wires connection with a custom board

[eleven-x_devteam]

Hi,

I just got a ppk2 and I am not sure which wire needs to be connected to where.

I am going to use this to measure current consumption but I've used only extarnal DUT + and  - connection between the old PPK and my custom board so I am confused with the new one.

Is it right to connect vout -> +,  vin -> - , GND -> GND? or just need vout and GND connected only?

Could someone clarify for me?

Thanks.

Try this for Ampere Meter mode supplying power from the DUT battery (disconnect battery from DUT first):

//                                      External Battery To VIN ->

//    |                                <- Supply to DUT From VOUT  |

If using Source Mode then just leave out the battery

Thank you for the answer.

Then if I don't want to connect the battery, I don't need to connet it to Vin and only use Vout and GND, right?

Verified Source mode worked well.
