Can we use PPK to measure in both directionhttps://devzone.nordicsemi.com/f/nordic-q-a/112169/can-we-use-ppk-to-measure-in-both-directionHi , I would like to know if we can use 2 PPK&#39;s in such way to measure both direction. As you can see in the diagram , the current can flow to the battery or can flow from battery to the Keithly.

Just to be clear, you should test this up against using a single PPK for measurement to confirm the results are as expected.</p> <p>I assume there also is some device you would be measuring the current draw on here?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
