https://devzone.nordicsemi.com/f/nordic-q-a/8306/why-is-the-current-consumption-in-system-on-too-high-1maI downloaded the power consumption example code to a nRF51-DK to measure the current consumption during SYSTEM ON and SYSTEM OFF state. For the SYSTEM ON state, I used the &quot;system-on-wakeup-on-rtc&quot; code. The current consumption was 4.4 mA and 1.2 mAen-USTelligent Community 13Wed, 22 Jul 2015 11:25:48 GMThttps://devzone.nordicsemi.com/thread/30011?ContentTypeID=1Wed, 22 Jul 2015 11:25:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cadb40b2-587f-4345-a0d3-8b51db45b7a5Johnson<p>@Wojtek: I use UNI-T UT61E multimeter. It has A, mA and uA ranges.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30013?ContentTypeID=1Wed, 22 Jul 2015 11:24:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cb207225-2ef0-4ddc-8168-1bd0ea1497e0Johnson<p>Thank you!

After programming the chip will stay in debug mode and that may consume about 1mA. The example you used was very old. Please try with our example in the lastest SDK, v9.0.</p> <p>The rtc example in \examples\peripheral\rtc should only consume about 4-5uA when running (SYSTEMON mode).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30010?ContentTypeID=1Tue, 21 Jul 2015 13:29:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bbc9619b-bebd-498e-9928-2c4bd4b1bb40Wojtek<p>Sorry for no answer, but could You tell me what equipment do You use to measure that range of current?</p><div style="clear:both;"></div>
