https://devzone.nordicsemi.com/f/nordic-q-a/26494/troubles-of-using-power-profiler-kit-1Dear friends, my current measuing instrument is Power Profiler Kit. I have some troubles when i use it. e.g. 1) how to completely stop an updating plot that a PPK draws? even i click the &quot;stop&quot; button on the desktop application, the plot it draws stillen-USTelligent Community 13Wed, 08 Nov 2017 01:33:00 GMThttps://devzone.nordicsemi.com/thread/104253?ContentTypeID=1Wed, 08 Nov 2017 01:33:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b893e442-58f2-48e4-9296-06216e135b30xvhongpeng<p>thank u very much.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104247?ContentTypeID=1Wed, 08 Nov 2017 01:31:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d89f52c4-3165-4760-a1e6-888efe3026d0xvhongpeng<p>thank u very much.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104246?ContentTypeID=1Tue, 07 Nov 2017 09:03:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:964607f1-79e6-436e-9742-ec1c71bfd87aStian R&#248;ed Hafskjold<p>And just to let you know. We are working on a completely new and better software for the PPK at the moment, which is not written in python.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104245?ContentTypeID=1Tue, 07 Nov 2017 08:48:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:82d45674-ddb3-4cdf-ab50-422179a94ad6Stian R&#248;ed Hafskjold<ol start="2"> <li> <p>You can have negative currents because of capacitance in the circuit. The PPK also uses algorithms to calculate the correct avarage current over the switching points, i.e. when the PPK switches measuring resistor value. This can lead to some negative spikes. The average current should be correct though.</p> </li> <li> <p>Seems like there are some problems with exporting picures. I will report it internally. Meanwhile you can use the snipping tool in windows, which should do pretty much the same thing. Sorry for the inconvenience.</p> </li> </ol><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104251?ContentTypeID=1Mon, 06 Nov 2017 08:08:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5db43d1-5989-4ba6-a26c-e743d09ee3a8erltot<p>Hi,</p> <p>Instead of bumping this question to get answer for issue 2) and 3), may i suggest you create two new questions and please consider accept my answer by clicking the grey circle with a check mark next to it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104250?ContentTypeID=1Wed, 01 Nov 2017 13:43:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fa1f9203-4169-4e4f-b115-acda20381723xvhongpeng<p>thank u all the same</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104249?ContentTypeID=1Wed, 01 Nov 2017 13:43:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0a65653f-102b-4d72-9fcf-0a1697ca8c06xvhongpeng<p>i cannot find &quot;plotter.start_log_thread()&#39; within ppk.py using &quot;find&quot;.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104252?ContentTypeID=1Wed, 01 Nov 2017 08:49:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a13e900-6b75-40de-855b-7af8e61df1a7xvhongpeng<p>thank u.it is stoped, while updating the data with a low speed.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104248?ContentTypeID=1Wed, 01 Nov 2017 08:40:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:06f4aa1c-76de-4c62-9ac4-476cf7f59c55erltot<ol> <li> <p>The reason your plot is not stopping may be because it is delayed, try commenting out line <code>196</code> in <code>ppk.py</code></p> <h1>plotter.start_log_thread()</h1> </li> </ol><div style="clear:both;"></div>
