Yeah, I realized that. I just thought I'd mention that, for a moment at least, I had seriously considered it. Luckily I came to my senses. Anyway, mine has apparently shipped. The tracking number shows it in transit with delivery next Wednesday.

Hehe, it's all good. Enjoy the meter!

I calibrated my AN8008's DC uA range today after finding it was way off - it read 89 uA when actual was 100 uA - the error may have been because a) I re-soldered the fuse holders and shunts on the PCB b) I may have messed it up by calibrating the other DC current ranges or c) both a and b. 

I used a 9V battery fed through a decade box and then my Keysight 34461A in series with the AN8008, I was able to set 90 uA with the 34461A reading 90.001 uA and then used my calibration process above to set 90 uA (it wouldn't do 100 uA) on the AN8008.  Comparison tests after doing this showed perfect alignment between the 2 meters, even at 2 uA DC.

I might be dumb and have just missed it reading through all the pages, but what is the burden voltage on this meter as far as a mV/mA estimate?

evava:
There are just two shunts, 100Ohm and 0.01Ohm (about 0.03Ohm across the terminals because of fuse), which meter uses for 99.99uA(lowest range) resp. 9999mA(highest range).
If I calculate it correctly, that means 10mV/0.1mA resp. 100mV/10000mA (300mV/10000mA across terminals) ;)

There are other ranges, but they use one of these two shunts.
