You can do up to 1mA in the uA range, the mA range only has a 1000mA range with 0.1mA resolution, i.e. worst case mA is with one digit after the decimal point.

That doesn't sound too bad on paper but I often have things which wobble around the 1-2mA range, sometimes dipping below 1mA. That would be impossible to measure with this meter.

It's a good meter for the money but you better have another meter with better milliamp range, eg. AN8002.

That's one reason why I bought both.

what's the worst case? 999.9uA jumps to 001.0mA?

I don't have it handy and haven't used it much there yet.

You have to turn the range switch between uA and mA

More like 999.9uA jumps to 0L

What would you expect this meter to do when set to uA?

I agree the A range should be one decade lower, if that is what is required for this chipset.
