mA??

my DMM has a current scale that ranges from (up to) 10A down to 200uA. 
sure, the resistance of the leads, the shunt, and also the inductance of 
the leads will all lead to an "impure" reading, but you're still applying 
battery voltage to the circuit, and the circuit will draw what it draws... 
and within a reasonable margin of error you can read that with a good DMM, 
down to a little less than 1uA. the 4-100uA range that you're trying to 
achieve shouldn't pose a problem, unless you're trying to use an analog 
meter, or a $5 special.
