I measure a couple of uA with a current clamp on a regular basis - Imon current on laser diodes. Just a pF of capacitance from a scope probe on these signals is more than enough to screw everything up. At this incredibly low level, the signal isn't terribly accurate, but its very repeatable and precise measurement to measurement. The current clamp I use is guaranteed accurate to 1% at anything over 10mA.
Agreed, I see that now. And yes, for measurements in the mA range, a shunt resistor is not a bad way to go - limited voltage drop at those levels.
Once again, really nice job on the review of the DMM. It really is a pretty nice unit for the cost.
