PPK reports different average current if trigger is running.

Question

Take a look at these screenshots. With the trigger enabled, the average current consumption is reported at 13.21uA. With the trigger disabled , the average current consumption is 5uA. 
 So which one is correct? 
 
 
 Average window with Trigger On 
 
 Average window with Trigger Off

This might be because the triggering is causing a lot of glitches. As stated in the user guide: 
 
 What it forgets to mention is that a lot of triggering can also cause glitches in the average plot, since the trigger window has the higher priority due to it's high accuracy. I also see that your max value is much lower on the second image, and will clearly be visible on the graphs. 
 Without looking at the actual plots you have, it is hard to say what exactly is causing this (since I haven't seen it before), but the avg: number is reporting the average for the full average window. Make sure the whole window is populated. You may also try to compare e.g sleep values by using the cursors, and see if the average number is different there with and without the trigger enabled. 
 I would assume the data without the trigger active is the correct number, but please edit you post with the plot screenshots so that we can be sure. Also, you should calibrate your resistor values, they doesn't seem correct to me. To do this, measure the output voltage of the External DUT, insert a resistor (one at a time) to draw 30µA, 1mA and 10mA. So for e.g Mid , the new value will be 
 1mA/measurement 28. I.e, if you measure 0.9mA, the new value will be 1/0.9 28=31.11.
