An alternative method is to put a low value R in series with the 
current and then connect the meter across the R as if it were a 
voltmeter, with the appropriate resistor in series with the meter. If 
you use a potentiometer as the voltmeter resistor you can calibrate 
it exactly very easily.

You may already know this but some others might find it useful.
