 first I have to admit that I&amp;#39;m a total rookie in &amp;quot;electricity&amp;quot;. I know BLE software-side but just started to learn the hardware stuff.
I just received my PPK and connected it with the nrf52DK (as explained in the infocenter).
It shows a negative</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 06 Jun 2017 10:31:30 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/22195/nrf52-dk-ppk-negative-current" /><item><title>RE: nRF52 DK PPK Negative Current</title><link>https://devzone.nordicsemi.com/thread/87245?ContentTypeID=1</link><pubDate>Tue, 06 Jun 2017 10:31:30 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:12fd2b8e-3135-442f-81d4-4e6834db783d</guid><dc:creator>Ken Matsui</dc:creator><description>&lt;p&gt;Did you cut the SB9 on nRF5 DK?
Please refer the detail from PPK UserGuide.
&lt;a href="http://infocenter.nordicsemi.com/pdf/PPK_User_Guide_v1.0.pdf"&gt;infocenter.nordicsemi.com/.../PPK_User_Guide_v1.0.pdf&lt;/a&gt;&lt;/p&gt;
&lt;blockquote&gt;
&lt;h3&gt;I am only measuring noise&lt;/h3&gt;
&lt;p&gt;Make sure you have prepared the nRF5x DK for power measurements by cutting the SB9 as described in Step 1 in Quick start.&lt;/p&gt;

&lt;p&gt;The &lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.tools/dita/tools/power_profiler_kit/PPK_user_guide_Intro.html?cp=5_6"&gt;supported operating systems&lt;/a&gt; for the PPK software is Microsoft Windows 7/8/10.&lt;/p&gt;
&lt;p&gt;But, the PPK desktop application is developed using Python, which works on a number of platforms. However, it is recommended to use the PPK only with Microsoft Windows, as the tool has not been tested on other platforms. You can also test with Otti. &lt;a href="https://devzone.nordicsemi.com/blogs/1058/new-power-optimization-tool-called-otii-that-runs-/"&gt;Otii&lt;/a&gt; should support Windows, Linux, and macOS&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF52 DK PPK Negative Current</title><link>https://devzone.nordicsemi.com/thread/87244?ContentTypeID=1</link><pubDate>Fri, 19 May 2017 18:58:02 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:bd6c9cd8-84e2-42d1-b6c6-1e2a74521579</guid><dc:creator>Daniel Wang</dc:creator><description>&lt;p&gt;You could try Otii&lt;/p&gt;
