https://devzone.nordicsemi.com/f/nordic-q-a/117251/how-to-use-ppk2-measure-current-of-custom-boardHi, I just got a PPK2, I&#39;m going to measure the current of a nrf52 custom board, which is supply with Li-ion battery. Should I connect GND on PPK2 to battery(-) when I use Ampere meter mode? If not, how should I connect the wire to get power consumptionen-USTelligent Community 13Mon, 14 Apr 2025 05:34:09 GMThttps://devzone.nordicsemi.com/thread/531618?ContentTypeID=1Mon, 14 Apr 2025 05:34:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:09b2812b-a314-4588-a828-572f61beb8a1RohitSalavi<p>Hello,</p> <p>I have a custom nRF52820 board powered by a coin cell, and I want to measure its power consumption using the Nordic Power Profiler Kit 2 (PPK2).</p> <p>Could you please explain the correct connection setup for measuring the board&#39;s power consumption, and which mode the PPK2 should be set to during measurement?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/514887?ContentTypeID=1Fri, 13 Dec 2024 12:46:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2aadeece-6db1-4b34-b14e-e39af8945f77PaKa<p>The current measurement on the PPK2 must always be on the high side, you can&#39;t measure the current in the ground path. This can be seen as the voltage range is 0.8V to 5V.</p> <p>VIN should be battery plus, VOUT should be target input (nRF52 board) and GND should be connected to board GND.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/514864?ContentTypeID=1Fri, 13 Dec 2024 10:14:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3af71991-79d5-43b4-a7e3-bbd700cbfa36Charlie[deleted]<div style="clear:both;"></div>
