Watch out for the Heisenberg uncertainty principle (you change what 
you measure): sensitive ammeters work by introducing, and measuring a 
voltage drop.

This voltage drop will affect your measurement (reducing the device 
current). Either this voltage drop needs to be compensated for, or 
avoided by using clip-on type of ammeters that measure the magnetic 
field caused by the device-current flowing through a conductor wired 
across the power-jumpers. Extech makes very sensitive (0.1mA and 1mA 
resolution) clip on meters. Search for Extech modell No: EX-380942 
for example.
