Artifact amplitude box settings

Hello!
I just wanted to ask whether the max voltage that we can set on this box has to be in millivolts (mV) or microvolts. I'm asking because this is not explicitly specified in the box description and mV can be interpreted both ways?
Thank you for helping me w this noob question,
Cheers
Isabel
