The scale of each meter manufacturer will be different. You'll need to refer to the owners manual to determine the proper setting.
Remember that an ammeter is used INLINE with the electrical device to determine current draw. Do NOT put the test leads of an ammeter across the two leads of the service voltage.

The setting for microamps on an amp meter is typically selected using a switch or dial on the meter itself. Look for a setting labeled "µA" or "microamps" on the meter and switch to that setting to measure current in microamps. Make sure to follow the instructions provided with the amp meter for accurate readings.
There are 1000 microamps in one milliamp. Each derived SI unit in each direction is three decimal places as in all engineering form.
Yes, 10000 microamps (µA) is smaller than 1 amp. 1 amp is equal to 1,000,000 microamps, so 10000 µA is equal to 0.01 amps.
Registering 2 amps on an electrical meter could indicate that there are two separate circuits drawing 1 amp each, or it could mean that there is a single circuit with a total load of 2 amps. The meter simply sums up the current flowing through each circuit it is measuring.
There is no direct conversion from amps to milliwatts because milliwatts measure power and amps measure current. The power in milliwatts would depend on the voltage as well. To calculate power in milliwatts when current in amps and voltage in volts are given, use the formula: Power (mW) = Current (A) x Voltage (V) x 1000.
The smallest size in breaker panels is 30 amps and the smallest breakers that can be installed into a 30 amp panel are15 amps. If more info is needed go to the discussion page tab and explain what you are trying to do.
