 I&amp;#39;ve been trying to use the nordic power profiler v1.1 with my nRF52 development board to figure out how much current is consumed during operation. 
 I used the power profiler app in nRF connect PC (latest update) to view the output and got something</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 06 Jul 2018 13:39:15 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/36162/power-profiler-graph-is-in-negative-region-and-average-current-also-appears-to-be-negative" /><item><title>RE: power profiler graph is in negative region and average current also appears to be negative</title><link>https://devzone.nordicsemi.com/thread/139270?ContentTypeID=1</link><pubDate>Fri, 06 Jul 2018 13:39:15 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:48832de4-96c3-4d9d-a5c8-598fba4836ba</guid><dc:creator>haakonsh</dc:creator><description>&lt;p&gt;Hey Shankmukh,&lt;/p&gt;
&lt;p&gt;You need to cut SB9 on the DK to measure the current of the on-board nRF52832 with the PPK, but you do not need to solder SB12.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The USB supply is faulty on the PPK so you need to power the PPK through the DK, but I believe you can leave SB9 intact if you&amp;#39;re going to measure on an external board.&lt;/p&gt;
&lt;p&gt;-Edit:&lt;br /&gt;This issue is not present in newer PPK revisions.&lt;/p&gt;
&lt;p&gt;Cheers,&lt;/p&gt;
