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.
