https://devzone.nordicsemi.com/f/nordic-q-a/75649/current-measurement-thingy-91Hello, everyone, I got a Thingy91 and I would have liked to be able to measure the current that passes through the NB-IoT modem, for that, I followed this tutorial : https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/hw_power_current_measurementen-USTelligent Community 13Wed, 26 May 2021 14:03:36 GMThttps://devzone.nordicsemi.com/thread/311844?ContentTypeID=1Wed, 26 May 2021 14:03:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b87d61e-245a-489e-b29d-22127fbc0310ActiTAG<p>Thank you very much! I plug it into 20Amax and now it&#39;s working, I was on the &micro;A/mA.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/311836?ContentTypeID=1Wed, 26 May 2021 13:48:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:428acf41-117c-42f9-9ccb-361498fa7e09awneil<p>A multimeter isn&#39;t going to give you useful readings - the current is very &quot;bursty&quot;.</p> <p>You need something like this:</p> <p><a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/Power-Profiler-Kit-2">www.nordicsemi.com/.../Power-Profiler-Kit-2</a></p> <p>What range did you have the meter set to?</p> <p>A low current range will likely have too high a burden voltage:</p> <p><a href="https://zone.ni.com/reference/en-XX/help/370384V-01/dmm/burden_voltage/#:~:text=Burden%20voltage%20is%20the%20voltage,kept%20as%20low%20as%20possible">https://zone.ni.com/reference/en-XX/help/370384V-01/dmm/burden_voltage/#:~:text=Burden%20voltage%20is%20the%20voltage,kept%20as%20low%20as%20possible</a>.</p><div style="clear:both;"></div>
