Am I checking battery draw correctly?

I have a drain overnight....Trying to figure it out today.

Battery holds charge overnight when disconnected from the system. 12.68v held for over 10hours.
Engine running gets me 13.88v (battery was low during this test...not sure if that affects readings or not).

Load tested battery and looks OK right? :






Then I checked draw, but 9mA seems far too low...Maybe I am doing something wrong here?

I have my DMM set to COM and 20A. I'm relatively new to all this type of stuff.



Thanks,
Robert
